and

Bernard L. Feringa
University of Groningen, the Netherlands

“for the design and synthesis of molecular machines”

They developed the world’s smallest machines

A tiny lift, artificial muscles and miniscule motors. The Nobel Prize in Chemistry 2016 is awarded to Jean-Pierre Sauvage, Sir J. Fraser Stoddart and Bernard L. Feringa for their design and production of molecular machines. They have developed molecules with controllable movements, which can perform a task when energy is added.

The development of computing demonstrates how the miniaturisation of technology can lead to a revolution. The 2016 Nobel Laureates in Chemistry have miniaturised machines and taken chemistry to a new dimension.

The first step towards a molecular machine was taken by Jean-Pierre Sauvage in 1983, when he succeeded in linking two ring-shaped molecules together to form a chain, called a catenane. Normally, molecules are joined by strong covalent bonds in which the atoms share electrons, but in the chain they were instead linked by a freer mechanical bond. For a machine to be able to perform a task it must consist of parts that can move relative to each other. The two interlocked rings fulfilled exactly this requirement.

The second step was taken by Fraser Stoddart in 1991, when he developed arotaxane. He threaded a molecular ring onto a thin molecular axle and demonstrated that the ring was able to move along the axle. Among his developments based on rotaxanes are a molecular lift, a molecular muscle and a molecule-based computer chip.

Bernard Feringa was the first person to develop a molecular motor; in 1999 he got a molecular rotor blade to spin continually in the same direction. Using molecular motors, he has rotated a glass cylinder that is 10,000 times bigger than the motor and also designed a nanocar.

2016’s Nobel Laureates in Chemistry have taken molecular systems out of equilibrium’s stalemate and into energy-filled states in which their movements can be controlled. In terms of development, the molecular motor is at the same stage as the electric motor was in the 1830s, when scientists displayed various spinning cranks and wheels, unaware that they would lead to electric trains, washing machines, fans and food processors. Molecular machines will most likely be used in the development of things such as new materials, sensors and energy storage systems.

Hormone


Melatonin
 – Think of melatonin as your biological clock. This hormone is responsible for the way you feel throughout the day as far as alertness is concerned. All those drowsy feelings? Blame the melatonin.

Serotonin – This is the one you can blame for PMS and your moody teenager. Serotonin controls your mood, appetite, and your sleep cycles.

Thyroxin – A form of thyroid hormone, thyroxin increases the rate of your metabolism and also affects protein synthesis, which is the process that cells go through to build protein.

Epinephrine – This is one that you have most likely heard of; it’s also called adrenaline. Among a whole list of other things, epinephrine is responsible for what is known as the, “fight or flight” response. This is the hormone that tells you when to fight and when it’s best to run. Some of the bodily responses demonstrated when this hormone kicks in are dilated pupils, increased heart rate, and tensing of the muscles.

Norepinephrine – Also called noradrenaline, this hormone controls the heart and blood pressure. Norepinephrine also contributes to the control of sleep, arousal, and emotions. Obvious effects take place when there is too much or too little of this hormone. Too much gives you an anxious feeling while too little can leave you feeling depressed or sedated.

Dopamine – This controls the heart rate and also assists in perception; deciphering what is real and what is not.

Antimullerian Hormone – An inhibitor for the release of prolactin, the protein responsible mainly for lactation.

Adiponectin – This is a protein hormone, it regulates metabolic processes such as the regulation of glucose.

Adrenocorticotropic Hormone – This assists in synthesizing corticosteroids, which are responsible for stress response, blood electrolyte levels, and other physiologic systems.

Angiotensinogen – Responsible for the narrowing of blood vessels; a process known as vasoconstriction.

Antidiuretic Hormone – This hormone is also known by other names, but it is mainly responsible for retaining water within the kidneys.

Atrial Natriuretic Peptide – A peptide hormone secreted by the cells of the heart and other muscles, it’s mostly involved with the control of water, sodium, potassium, and fat within the body.

Calcitonin – Aids in constructing bone and reducing blood calcium.

Cholecystokinin – Aids in the release of digestive enzymes for the pancreas and acts as an appetite suppressant.

Corticotrophin-Releasing Hormone – Releases cortisol in response to stress.

Erythropoietin – Stimulates the production of erythrocytes, which are blood cells responsible for delivering oxygen.

Follicle-Stimulating Hormone – Stimulates the follicles within the sex organs of both males and females.

Gastrin – Secretes gastric acid.

Ghrelin – Hunger stimulant as well as aiding in the secretion of the growth hormone.

Glucagon – Helps to increase the blood glucose level.

Growth Hormone-Releasing Hormone – As its name clearly implies, this hormone releases the growth hormone.

Human Chorionic Gonadotropin – Keeps the immune system from attacking a forming embryo during pregnancy.

Growth Hormone – Helps to stimulate growth and the reproduction of cells.

Insulin – Responsible for several anabolic effects, primarily glucose intake.

Insulin-Like Growth Factor – Has the same effects as insulin while also regulating the growth and development of cells.

Leptin – Slows down the appetite while simultaneously speeding up metabolism.

Luteinizing Hormone – Aids ovulation in women and testosterone production in men.

Melanocyte Stimulating Hormone – Produce melanocytes, which are responsible for the pigment in skin and hair.

Orexin – Increases the appetite while also increasing your alertness and energy levels.

Oxytocin – A hormone that plays a major role in reproduction, it aids in orgasm and is also responsible for the release of breast milk.

Parathyroid Hormone – Among other functions, this hormone is mainly responsible for the activation of Vitamin D.

Prolactin – A major contributor in sexual satisfaction and the production of breast milk.

Secretin – Inhibits gastric acid production.

Aldosterone – Mainly responsible for absorbing sodium in the kidneys to increase the volume of blood within the body.

Testosterone – The major male hormone, testosterone is responsible for sex drive, development of the sex organs, and the changes that take place during puberty.

Androstenedione – Essentially estrogen.

Estradiol – In males, this hormone is responsible for preventing what is basically known as cell death of the germ cells. In females, this hormone is in overdrive. Among other things, estradiol accelerates height and metabolism, maintains the blood vessels and skin, aids in water retention, and even aids in hormone-sensitive cancers.

Progesterone – A major contributor to the body’s support of pregnancy.

Lipotropin – Stimulates the production of pigment by aiding in melanin production.

Brain natriuretic peptide – Aids in reducing blood pressure.

Histamine – A hormone based in the stomach, histamine aids in the secreting of gastric acid.

Endothelin – Controls muscle contractions within the stomach.

Enkephalin – Simply a pain regulator.

WATER PURIFICATION

There are twenty-five methods to purify water, divided into four categories: separation, filtration, chemicals, oxidation.
There are five types of contaminants that are found in water: particulates, bacteria, minerals, chemicals, and pharmaceuticals. Methods to remove these elements range from simple and inexpensive to elaborate and costly. Often to achieve purely potable water, several technologies must be combined in a particular sequence. Listed here are general brief descriptions of the twenty-five methods to purify water.

SEPARATION: HEAT, LIGHT & GRAVITY

SEDIMENTATION gravitationally settles heavy suspended material.
BOILING WATER for 15 to 20 minutes kills 99.9% of all living things and vaporizes most chemicals.  Minerals, metals, solids and the contamination from the cooking container become more concentrated.
DISTILLATION boils and recondenses the water, but many chemicals vaporize and recondense in concentration in the output water.  It is also expensive to boil & cool water.
ULTRAVIOLET LIGHT is a good bactericide, but has no residual kill, and works only in clearly filtered water.   Still in its infancy stage is a new technology involving super white light.


CHEMICALS

CHLORINE is common, cheap, but extremely toxic.  It does not decrease physical or chemical contamination, it does increase colesterol formations, is a carcinogen, and causes heart disease.
BROMINE, used in pools and spas, doesn’t smell or taste as bad and doesn’t kill bacteria very well.
IODINE is not practical, and is mostly used by campers.
HYDROGEN PEROXIDE kills bacteria with oxygen, is chemically made and is very toxic.  It is used in emergencies.
SILVER is an effective bactericide but a cumulative poison which concentrates and doesn’t evaporate.
NONTOXIC ORGANIC ACIDS should be used with caution in large water plants only.
LIME AND MILD ALKALINE AGENTS should also be used with caution only by large water plants, or only for laundry.
NEUTRALIZING CHEMICALS react with the unwanted chemicals and produce outgases and a sediment, but levels of need vary.
COAGULATION-FLOCCULATION adds chemicals which lump together suspended particles for filtration or separation.
ION EXCHANGE exchanges sodium from salt for calcium or magnesium, using either glauconite (greensand), precipitated synthetic organic resins, or gel zeolite, thus softening the water.  Minerals, metals, chemicals or odors are not affected, and the water is salty to drink.

FILTRATION

SLOW SAND of 1 cubic meter passes about 2 liters/min, and does a limited bacteria removal.
PRESSURE SAND of 1 cubic meter passes about 40gpm and must be backwashed daily.
DIATOMACEOUS EARTH removes small suspended particles at high  flow rates, must be daily backwashed and is expensive.
POROUS STONE/CERAMIC filters are small but expensive, and do not effect chemicals, bacteria or odors.
PAPER or CLOTH filters are disposable and filter to one micron, but do not have much capacity.
CHARCOAL:
-COMPRESSED CHARCOAL/CARBON BLOCK is the best type of charcoal  filter, can remove chemicals and lead, but is easily clogged,  so  should be used with a sediment prefilter.
-GRANULAR CHARCOAL is cheaper, but water can flow around the  granules without being treated.
-POWDERED CHARCOAL is a very fine dust useful for spot cleaning  larger bodies of water, but is messy and can pass through some filters and be consumed.
REVERSE OSMOSIS uses a membrane with microscopic holes that require 4 to 8 times the volume of water processed to wash it in order to remove minerals and salt, but not necessarily chemicals and bacteria.
ENZYMES &BACTERIA combined can remove contaminants, reduce sludge, and even digest oil. See recent article on enzymes & bacteria.
PLANTS There are numerous plants, animals and organisms that are quite effective in filtering water.

OXIDATION

AERATION sprays water into the air to raise the oxygen content, to break down odors, and to balance the dissolved gases.  However, it takes space, is expensive, and picks up contaminants from the air.
OZONE is a very good bactericide, using highly charged oxygen molecules to kill microorganisms on contact, and to ozidize and flocculate iron, manganese and other dissolved minerals for post-filtration and backwashing.
ELECTRONIC PURIFICATION and DISSOLVED OXYGEN GENERATION creates super oxygenated water in a dissolved state that lowers the surface tension of the water and effectively treats all three types of contamination: physical, chemical and biological.

ANTIBIOTICS RESISTANCE

Antimicrobial resistance happens when microorganisms (such as bacteria, fungi, viruses, and parasites) change when they are exposed to antimicrobial drugs (such as antibiotics, antifungals, antivirals, antimalarials, and anthelmintics). Microorganisms that develop antimicrobial resistance are sometimes referred to as “superbugs”.

As a result, the medicines become ineffective and infections persist in the body, increasing the risk of spread to others.

Why is antimicrobial resistance a global concern?

New resistance mechanisms are emerging and spreading globally, threatening our ability to treat common infectious diseases, resulting in prolonged illness, disability, and death.

Without effective antimicrobials for prevention and treatment of infections, medical procedures such as organ transplantation, cancer chemotherapy, diabetes management and major surgery (for example, caesarean sections or hip replacements) become very high risk.

Antimicrobial resistance increases the cost of health care with lengthier stays in hospitals and more intensive care required.

Antimicrobial resistance is putting the gains of the Millennium Development Goals at risk and endangers achievement of the Sustainable Development Goals.

What accelerates the emergence and spread of antimicrobial resistance?

Antimicrobial resistance occurs naturally over time, usually through genetic changes. However, the misuse and overuse of antimicrobials is accelerating this process. In many places, antibiotics are overused and misused in people and animals, and often given without professional oversight. Examples of misuse include when they are taken by people with viral infections like colds and flu, and when they are given as growth promoters in animals and fish.

Antimicrobial resistant-microbes are found in people, animals, food, and the environment (in water, soil and air). They can spread between people and animals, and from person to person. Poor infection control, inadequate sanitary conditions and inappropriate food-handling encourage the spread of antimicrobial resistance.

Present situation

Resistance in bacteria

Antibiotic resistance is present in every country.

Patients with infections caused by drug-resistant bacteria are at increased risk of worse clinical outcomes and death, and consume more health-care resources than patients infected with non-resistant strains of the same bacteria.

Resistance in Klebsiella pneumoniae – common intestinal bacteria that can cause life-threatening infections – to a last resort treatment (carbapenem antibiotics) has spread to all regions of the world. K. pneumoniae is a major cause of hospital-acquired infections such as pneumonia, bloodstream infections, and infections in newborns and intensive-care unit patients. In some countries, because of resistance, carbapenem antibiotics do not work in more than half of people treated for K. pneumoniae infections.

Resistance in E. coli to one of the most widely used medicines for the treatment of urinary tract infections (fluoroquinolone antibiotics) is very widespread. There are countries in many parts of the world where this treatment is now ineffective in more than half of patients.

Treatment failure to the last resort of medicine for gonorrhoea (third generation cephalosporin antibiotics) has been confirmed in at least 10 countries (Australia, Austria, Canada, France, Japan, Norway, Slovenia, South Africa, Sweden and the United Kingdom of Great Britain and Northern Ireland).

WHO recently updated the treatment guidelines for gonorrhoea to address emerging resistance. The new WHO guidelines do not recommend quinolones (a class of antibiotic) for the treatment of gonorrhoea due to widespread high levels of resistance. In addition, treatment guidelines for chlamydial infections and syphilis were also updated.

Resistance to first-line drugs to treat infections caused by Staphlylococcus aureus—a common cause of severe infections in health facilities and the community—is widespread. People with MRSA (methicillin-resistant Staphylococcus aureus) are estimated to be 64% more likely to die than people with a non-resistant form of the infection.

Colistin is the last resort treatment for life-threatening infections caused by Enterobacteriaceae which are resistant to carbapenems. Resistance to colistin has recently been detected in several countries and regions, making infections caused by such bacteria untreatable.

Resistance in tuberculosis (TB)

WHO estimates that, in 2014, there were about 480 000 new cases of multidrug-resistant tuberculosis (MDR-TB), a form of tuberculosis that is resistant to the 2 most powerful anti-TB drugs. Only about a quarter of these (123 000 cases) were detected and reported. MDR-TB requires treatment courses that are much longer and less effective than those for non-resistant TB. Globally, only half of MDR-TB patients were successfully treated in 2014.

Among new TB cases in 2014, an estimated 3.3% were multidrug-resistant. The proportion is higher among people previously treated for TB, at 20%.

Extensively drug-resistant tuberculosis (XDR-TB), a form of tuberculosis that is resistant to at least 4 of the core anti-TB drugs, has been identified in 105 countries. An estimated 9.7% of people with MDR-TB have XDR-TB.

Resistance in malaria

As of July 2016, resistance to the first-line treatment for P. falciparum malaria (artemisinin-based combination therapies, also known as ACTs) has been confirmed in 5 countries of the Greater Mekong subregion (Cambodia, the Lao People’s Democratic Republic, Myanmar, Thailand and Viet Nam). In most places, patients with artemisinin-resistant infections recover fully after treatment, provided that they are treated with an ACT containing an effective partner drug. However, along the Cambodia-Thailand border, P. falciparum has become resistant to almost all available antimalarial medicines, making treatment more challenging and requiring close monitoring. There is a real risk that multidrug resistance will soon emerge in other parts of the subregion as well.The spread of resistant strains to other parts of the world could pose a major public health challenge and jeopardize important recent gains in malaria control.

A “WHO Strategy for Malaria Elimination in the Greater Mekong subregion (2015-2030)” was endorsed by all 5 countries, as well as China.

Resistance in HIV

In 2010, an estimated 7% of people starting antiretroviral therapy (ART) in developing countries had drug-resistant HIV. In developed countries, the same figure was 10–20%. Some countries have recently reported levels at or above 15% amongst those starting HIV treatment, and up to 40% among people re-starting treatment. This requires urgent attention.

Increasing levels of resistance have important economic implications as second and third-line regimens are 3 times and 18 times more expensive, respectively, than first-line drugs.

Since September 2015, WHO has recommended that everyone living with HIV start on antiretroviral treatment . Greater use of ART is expected to further increase ART resistance in all regions of the world. To maximize the long-term effectiveness of first-line ART regimens, and to ensure that people are taking the most effective regimen, it is essential to continue monitoring resistance and to minimize its further emergence and spread. In consultation with countries, partners and stakeholders, WHO is currently developing a new “Global Action Plan for HIV Drug Resistance (2017-2021)“.

Resistance in influenza

Antiviral drugs are important for treatment of epidemic and pandemic influenza. So far, virtually all influenza A viruses circulating in humans were resistant to one category of antiviral drugs – M2 Inhibitors (amantadine and rimantadine). However, the frequency of resistance to the neuraminidase inhibitor oseltamivir remains low (1-2%). Antiviral susceptibility is constantly monitored through the WHO Global Influenza Surveillance and Response System.

Need for coordinated action

Antimicrobial resistance is a complex problem that affects all of society and is driven by many interconnected factors. Single, isolated interventions have limited impact. Coordinated action is required to minimize the emergence and spread of antimicrobial resistance.

All countries need national action plans on AMR.

Greater innovation and investment are required in research and development of new antimicrobial medicines, vaccines, and diagnostic tools.

WHO’s response

WHO is providing technical assistance to help countries develop their national action plans, and strengthen their health and surveillance systems so that they can prevent and manage antimicrobial resistance. It is collaborating with partners to strengthen the evidence base and develop new responses to this global threat.

WHO is working closely with the Food and Agriculture Organization of the United Nations (FAO) and the World Organisation for Animal Health (OIE) in a ‘One Health’ approach to promote best practices to avoid the emergence and spread of antibacterial resistance, including optimal use of antibiotics in both humans and animals.

A global action plan on antimicrobial resistance was adopted by Member States at the Sixty-eighth World Health Assembly and supported by the governing bodies of FAO and OIE in May and June 2015. The goal of the global action plan is to ensure, for as long as possible, continuity of successful treatment and prevention of infectious diseases with effective and safe medicines that are quality-assured, used in a responsible way, and accessible to all who need them.

Oats

Reduces Cholesterol:

A soluble fiber found in oats called beta-glucan has been found to work effectively in lowering LDL or “bad” cholesterol level in blood without affecting the HDL or “good” cholesterol level. Oats is also a rich source of Tocotrienols that affect cholesterol synthesis and reduces cholesterol in blood. Research shows that eating a bowl of oatmeal each day reduces the general cholesterol level in blood by nearly 20%.

blood cells blocked by triglycerides

Controls Blood Pressure:

Although, high blood pressure itself has no symptoms, but it can lead to serious damage of the heart, arteries and blood vessels and lead to various other serious complications. But a daily serving of oats rich in soluble and half soluble fibers helps reduce hypertension, high blood pressure and also the intake of anti-hypertensive medicines.

blood pressure

Protects against Heart Disease:

Study shows that oatmeal contains a unique antioxidant named Avenanthramides that prevents the harmful free radicals from affecting the HDL levels in blood, thereby reducing the risk ofcoronary heart disease. In addition, the helpful phytochemicals called Lignans present in oats keep the heart healthy.

High Blood Pressure and Heart Disease

Protects against Cancer:

Although, oats doesn’t have the capacity to prevent cancer, but including it in your daily diet can significantly lower the risk of certain cancers. The antioxidants found in oats blocks the harmful toxins also known as free radicals from mingling with the DNA cells that can lead to cancer. The high fiber content of oats helps cut the risk of colorectal cancer and the lignans-enterolactone in particular protects against hormone related cancers such as, prostate cancer, breast cancer and ovarian cancer.

 Helps Weight Loss:

For those who are trying to lose some pounds, oats is a healthy addition to their diet. Oats being very low in calories (147/cup) does not add extra fat to the body and the high fiber content in oats absorbs water and provides a high level of satiety helping stay full for a longer time and keeping hunger at bay. Research shows that a daily consumption of oatmeal also helps prevent obesity and issues of excess weight gain  in children.

Reduces Risk of Type 2 Diabetes:

Research shows that daily consumption of whole grains such as oats reduces the risk of diabetes by approximately 60%. It is also beneficial for those suffering with diabetes because oats help stabilize the level of glucose in blood. The beta-glucans present in oats slows down the digestion process and extends carbohydrate absorption, thereby controlling fluctuations in blood sugar level.

diabetes problems

Improves Defense of Immune System:

The soluble fibers called beta-glucan found in oats enhance the defense of immune system against bacteria, fungi, parasites and viruses.  It speeds up immune system’s response to infections. It not only helps the immune cell neutrophils to locate the infected site more swiftly, but also helps eliminate the bacteria and heal the infection more quickly.

Reduces Asthma in Children:

Asthma is one of the most common diseases among children and more than 200 million people suffer from it around the world.  A Finnish study of 1293 children has shown that early introduction of whole grains such as oats in children’s diet significantly reduces the chances of developing asthma.

Prevents cardiovascular disease: “The antioxidants present in oats are beneficial for heart disease and the dietary fibers help lower the bad cholesterol (LDL) without affecting the good cholesterol (HDL)”, says Dr. Manoj K. Ahuja. Oats also contain plant lignans, especially enterolactone, which protect against heart disease. Thus, oats help reduce your cholesterol levels and keep your heart healthy. He adds, “It is a key food item that has proven to be good for the heart”.

2. Prevents constipation: Oats are a rich source of fiber, both soluble and insoluble, which helps in regulating bowel movements and hence prevents constipation.

3. Controls blood sugar levels: Since oats help stabilise blood sugar and reduce risk of type-2 diabetes, diabetics should consume oats regularly. The high fiber and complex carbohydrates slow down the conversion of this whole food to simple sugars, and beta-glucan delays the fall in blood sugar levels before meals and slows the rise after a meal.

4. Reduces cancer risk: Lignan, the same compound which helps prevent cardiovascular disease also “helps reduce chances of hormone-related cancers like breast, prostate and ovarian cancer”, according to the American Cancer Society. Therefore, eating oats is good for both men and women.

5. Reduces hypertension: If you suffer from high blood pressure, a daily dose of oats will help combat this problem and in turn, lower risk of hypertension.

6. Rich source of magnesium:  Oats are also a rich source of magnesium, which is key to enzyme function and energy production, and helps prevent heart attacks and strokes by relaxing blood vessels, aiding the heart muscle, and regulating blood pressure. The high levels of magnesium nourish the body’s proper use of glucose and insulin secretion.

7. Supports weight loss: Oats is a low calorie food which slows digestion and makes you feel full longer. Thus, reducing your cravings and helping you shed a few pounds. Cholecystokinin, a hunger-fighting hormone, is increased with the oatmeal compound beta-glucan.

8.  Enhances immune response to disease: The unique fiber in oatmeal called beta-gluten has been shown to help neutrophils travel to the site of an infection more quickly and it also enhances their ability to eliminate the bacteria they find there.

9. Protects skin: Oats have been used as a soothing agent to relieve itch and irritation while also providing an array of benefits for the skin. According to The American Academy of Dermatology, “Oatmeal is able to normalise the skin’s pH. It also helps moisturise and soften the skin.”

Diamagnetic, Paramagnetic, and Ferromagnetic Materials

When a material is placed within a magnetic field, the magnetic forces of the material’s electrons will be affected. This effect is known as Faraday’s Law of Magnetic Induction. However, materials can react quite differently to the presence of an external magnetic field. This reaction is dependent on a number of factors, such as the atomic and molecular structure of the material, and the net magnetic field associated with the atoms. The magnetic moments associated with atoms have three origins. These are the electron motion, the change in motion caused by an external magnetic field, and the spin of the electrons.

In most atoms, electrons occur in pairs. Electrons in a pair spin in opposite directions. So, when electrons are paired together, their opposite spins cause their magnetic fields to cancel each other. Therefore, no net magnetic field exists. Alternately, materials with some unpaired electrons will have a net magnetic field and will react more to an external field. Most materials can be classified as diamagnetic, paramagnetic or ferromagnetic.

 

Diamagnetic materials have a weak, negative susceptibility to magnetic fields. Diamagnetic materials are slightly repelled by a magnetic field and the material does not retain the magnetic properties when the external field is removed. In diamagnetic materials all the electron are paired so there is no permanent net magnetic moment per atom. Diamagnetic properties arise from the realignment of the electron paths under the influence of an external magnetic field. Most elements in the periodic table, including copper, silver, and gold, are diamagnetic.

Paramagnetic materials have a small, positive susceptibility to magnetic fields. These materials are slightly attracted by a magnetic field and the material does not retain the magnetic properties when the external field is removed. Paramagnetic properties are due to the presence of some unpaired electrons, and from the realignment of the electron paths caused by the external magnetic field. Paramagnetic materials include magnesium, molybdenum, lithium, and tantalum.

Ferromagnetic materials have a large, positive susceptibility to an external magnetic field. They exhibit a strong attraction to magnetic fields and are able to retain their magnetic properties after the external field has been removed. Ferromagnetic materials have some unpaired electrons so their atoms have a net magnetic moment. They get their strong magnetic properties due to the presence of magnetic domains. In these domains, large numbers of atom’s moments (1012 to 1015) are aligned parallel so that the magnetic force within the domain is strong. When a ferromagnetic material is in the unmagnitized state, the domains are nearly randomly organized and the net magnetic field for the part as a whole is zero. When a magnetizing force is applied, the domains become aligned to produce a strong magnetic field within the part. Iron, nickel, and cobalt are examples of ferromagnetic materials. Components with these materials are commonly inspected using the magnetic particle method.

Master Tonic

This homemade tonic is made of natural, organic ingredients that destroy many bacteria when combined. It is also a potent antiviral and antifungal formula that fights candida. It increases circulation of both blood and lymph, fights inflammation and may actually knock out the common cold and flu — and it’s so easy to prepare. But, before you check out the recipe, take a closer look at what makes this tonic so potent.

Garlic

garlic

Garlic is a strong antibiotic in itself. Allicin, one of the active compounds of freshly crushed garlic, has a variety of antimicrobial activities with a wide range of health benefits. But unlike pharmaceutical antibiotics that kill millions of friendly bacteria in the gut, garlic increases the level of healthy bacteria.

Research conducted by the department of biological chemistry at the Weizmann Institute of Science in Israel found that garlic is effective on a wide range of Gram-negative and Gram-positive bacteria, including multidrug-resistant strains of E. coli. It’s also effective on candida and even parasitic activity, including some major human intestinal parasites such as Entamoeba histolytica and Giardia lamblia.

Turmeric

Turmeric’s active compound curcumin lowers the levels of two enzymes in the body that cause inflammation, according to University of Maryland Medical Center. Because of its ability to reduce inflammation, it may help relieve osteoarthritis pain. Turmeric is also effective for helping treat ulcerative colitis, stomach ulcers, heart disease and even cancer.

Ginger

ginger

Ginger has a variety of powerful therapeutic and preventive effects and has been used for thousands of years for the treatment of ailments ranging from colds to cancer. According to research published in The National Center for Biotechnology Information, ginger root has a high level of antioxidant activity. It also has anti-inflammatory properties and is an anti-nausea agent. Other benefits include cardiovascular and colon cancer-preventing benefits.

Onions

Onions are rich in sulfur-containing compounds that are responsible for their pungent odor and otherhealth-promoting benefits. Studies show that onions possess antibacterial, antiparasitic and antifungal properties. According to Whfoods, onions also provide protection for the heart and blood vessels and can help increase bone density, which may benefit women of menopausal age. In addition, onions provide important anti-inflammatory and antioxidant benefits, and have been shown to lower the risk of several cancers, even when consumed in only moderate amounts (meaning one to two times per week).

Red chilies

Chili peppers contain a substance called capsaicin, which give them their characteristic pungency. Capsaicin fights inflammation and offers natural pain relief for osteoarthritis. And the hotter the chili pepper, the more capsaicin it contains. The hottest varieties include habanero, Scotch bonnet peppers and jalapenos.

Notably, red chili peppers have been shown to reduce blood cholesterol, triglyceride levels and platelet aggregation, while increasing the body’s ability to dissolve fibrin, a substance that’s vital to the formation of blood clots. In fact, cultures that frequently eat hot peppers have a much lower rate of heart attack, stroke and pulmonary embolism. What also makes chili peppers a great addition to this tonic is their ability to clear congestion from the lungs and nose. They also boost immunity and help the body defend itself against invading pathogens.

Horseradish

horseradish

Horseradish is a powerful and pungent root vegetable that contains a wide variety of health benefits, including its ability to aid weight loss, lower blood pressure, alleviate respiratory conditions, build strong bones, improve immune system health, stimulate healthy digestion and promote heart health. Whether it’s fighting the flu and respiratory disorders or combating tonsillitis and urinary tract infections, horseradish can help keep you healthy.

Raw honey

Raw honey is pure, unfiltered and unpasteurized honey made by bees from the nectar of flowers. Apart from providing energy and antioxidants, raw honey is a natural antibacterial with wound-healing effects. In addition, raw honey reacts with the body’s fluids to make hydrogen peroxide, creating an inhospitable environment for bacteria.

Apple cider vinegar

Apple cider vinegar (ACV) is extremely useful as a food preservative because of its ability to inhibit bacteria — like E. coli — from growing in the food and spoiling it. But there are many more uses for ACV, including its many health benefits. ACV lowers blood sugar levels, helps fight diabetes, helps aid in weight loss, lowers cholesterol and reduces your risk of heart disease. Some studies show that it can kill cancer cells and shrink tumors.

CHEMISTRY IN DAILY LIFE

Image result for chemistry in everyday life

Chemistry is a branch of science, which deals with the study of the composition, structure, properties, reactions, and behavior of substances. Hence, chemistry is termed as the central science. It is the essence of our everyday lives and occurs in the food we eat, the air we breathe, the water we drink, everything is a result of chemical processes.

In fact, emotions like love and hatred are also driven by chemistry. For a better understanding of the chemistry that is virtually everywhere around us, we have provided day-to-day examples in two sections. Firstly, examples of chemistry within our body and secondly, examples of chemistry that exist outside our body or occur around us.
Chemistry Within Us
Chemistry plays a vital role in our survival, and life without chemicals can’t even be imagined. They participate in the primary functions of the body, control our emotions, oversee the metabolic processes and keep diseases at bay. The oxygen that we breathe, the essential nutrients that we require, the genetic make-up of our body – the DNA and RNA – are all made up of different elements and compounds. Let us take a look at few such instances that involve chemistry, and are an integral part of our existence.
Composition of the Human Body

Roughly 96% of our body mass is made up of just 4 elements:- Oxygen, Carbon, Hydrogen and Nitrogen. The remaining 4% consists of around 60 elements that include sodium, potassium, calcium, zinc, and the list goes on.
The elements that are required in larger amounts are called macro-nutrients and the others that are needed in minute quantities, usually in parts per million or less, are called micro-nutrients. Chemically, the human body is made up of water and organic compounds- carbohydrates, proteins, lipids, and nucleic acids.
Metabolism

The organic processes taking place in the human body are termed as metabolism, which involves huge number of chemical reactions. The enzymes that are secreted by different organs act as biocatalysts that speed up the rate of these reactions, whereas the hormones regulate their occurrence, time, and speed.
Our well-being, smooth functioning and normal health depends on these metabolic processes. The coordination and simultaneous occurrences of these life processes in an orderly manner is the reason we are fit, healthy, and alive.
Respiration

Breathing is the exchange of gases between an organism and its environment. Respiration is a chemical process, which is a reaction between glucose or sugars with oxygen, that release energy. It is the process in which inhalation of oxygen from the air causes inflation of the lungs, and then deflation occurs by exhaling carbon dioxide into the environment.
The reaction that takes place during breathing is :-
C6H12O6 + 6O2 ➜ 6CO2 + 6H2O + Energy
Composition of Water

Water is the elixir of life on Earth. Hydrogen – a highly-combustible gas and Oxygen – a gas without which combustion is impossible, form a covalent bond with each other to create the most effective fire extinguisher, which is water. The chemical formula of water is H2O.
Yes! We drink a chemical everyday. Water is important for all the metabolic processes that occur inside our body. As Leonardo da Vinci stated “Water is the driving force of all nature.”
Feeling Hungry

When you feel hungry the hormone Ghrelin is secreted by the stomach that triggers hunger. It stimulates the release of the growth hormone. It plays a role in the release of Insulin and protection of the cardiovascular organs. So, the next time your stomach growls grab a bite because if you fast or skip meals, more Ghrelin is produced thus increasing your craving for food.
Digestion

Gastric acid is composed of hydrochloric acid (HCl) and large quantities of potassium chloride(KCl) and sodium chloride(NaCl) that is secreted by the parietal cells lining the stomach.
This gastric acid helps convert pepsinogen to pepsin which is responsible for the denaturing of the proteins in the stomach. It also kills the micro-organisms in the food before they can make you sick. The HCl neutralizes the acid present in the foods you eat thereby maintaining your body’s acidic or alkaline levels to keep you healthy.
Tears and Crying

Sometimes, crying is a natural reflex. Studies have shown that emotional tears contain more manganese, an element that affects temperament and more prolactin. Prolactin is a hormone that regulates milk production. This elimination of manganese and prolactin is thought to ease out tension building up in the body and you feel energized and rejuvenated. So, the next time you feel low and need to vent your emotions, don’t hold back. Just cry! It will help you feel better.
Chemistry of LOVE

We fall in love or are attracted to someone and have a feeling of belonging due to an increase in the secretion of -Phenylethylamine (PEA, or the “love chemical”) and the hormones testosterone and estrogen which promote mating.
When we fall in love, our brain releases dopamine, norepinephrine and pheromones consistently, which evoke the pleasure center in the brain leading to side effects such as increased heart rate, insomnia, an intense feeling of excitement, elation, and focused attention.
Coffee and Sleep

Coffee keeps you awake due to the presence of caffeine in it. This caffeine increases dopamine levels in our bodies that stimulates the ‘pleasure areas’ in our brain making us feel good. It increases the adrenaline secretion in the body and speeds up activity in the brain that keeps us awake.
Body Odor

Perspiration is a way in which the body cools itself. Body odor mainly originates from the Apocrine glands, which are found in the armpits, ears, breasts, the genitals, and hair follicles that become active at the onset of puberty. The sweat that these glands release is slight yellow in color due to the presence of fatty acids and proteins in it. The bacteria that thrive on our skin break down the secretions of the Apocrine glands and create smelly odors.
These are some of the examples of chemistry inside our body. Let’s look at some examples of chemistry in day-to-day life that take place around us.
Chemistry Around Us
Chemical reactions influence the stuff around us, and there are numerous instances where chemicals and chemistry helps us live a better life. The cooking of food, the clothes we wear, fertilizers that we use for crops, cement used for building our houses, the power plants that generate electricity, and many other processes depend on chemistry. The human dependence on this natural science is increasing and to understand this, here are a few examples that highlight the importance of chemistry around us.
Photosynthesis

Photosynthesis involves energy transformation and is a chemical process wherein plants, algae, and some bacteria produce their own food. It is the synthesis of glucose using carbon dioxide and water in presence of sunlight trapped by chlorophyll present in the leaves. The reaction which occurs is depicted as:
6 CO2 + 6 H2O + Light Energy ➜ C6H12O6 + 6 O2
Photosynthesis is the reverse process of respiration. They both are inter-dependent. We get an uninterrupted supply of oxygen, and plants get the carbon dioxide they need. Thus, photosynthesis plays a significant role in our day-to-day life.
Color of Meat

There are two types of meat: red and white. Red meat contains a highly pigmented protein called myoglobin that stores oxygen in the muscle cells. More the myoglobin in the cells, the redder is the meat. However, as meat is heated, the proteins break down and shrink in size.
When the interior of the meat reaches 170° F, hemichrome (a tan colored compound) levels rise, and the myoglobin becomes metmyoglobin, which gives well-done meat its brown-gray shade. White meat contains glycogen, which has a translucent “glassy” quality when it is raw. When it’s cooked, the proteins recombine, or coagulate, and the meat becomes opaque and whitish.
Apples Turning Brown

Apples contain an enzyme called polyphenol oxidase (PPO), also known as tyrosinase. Cutting an apple exposes its cells to the atmospheric oxygen and oxidizes the phenolic compounds present in apples. This is called the enzymatic browning that turns a cut apple brown. In addition to apples, enzymatic browning is also evident in bananas, pears, avocados and even potatoes.
Crying and Onions

When you cut an onion you break the cells that form the layers in an onion, thus releasing an enzyme Alliinase that reacts with a sulfur-containing compound known as ‘prensco’, which is also released while cutting. This reaction results in the formation of 1-propenyl sulfenic acid.
1-propenyl sulfenic acid is further converted to Propanethiol S-oxide, a volatile sulfur compound, by the enzyme LF-synthase (meaning Lachrymatory Factor synthesizing enzyme). This gas, known as the Lachrymatory factor (crying factor), reacts with the water in our eyes to form sulfuric acid causing a burning sensation in your eyes and indicating the tear gland to secrete tears.
Stain Removers

Soap is formed by the reaction between an alkali and a fatty acid. This produces a molecule with one hydrophilic (water-loving) and one lipophilic (fat-loving) ends. The lipophilic ends stick to oil, grease, or dirt. These get engulfed in the soap and are washed away with a fresh stream of water, leaving a clean surface behind.
This is just a physical reaction that takes place. Soap and stain removers act as emulsifiers which allow oil and water to mix and so the oily mixtures and difficult stains on body and clothes can be removed after application of soap, stain removers, and water.
Ripening of Fruits

A simple hydrocarbon gas ethylene switches on the necessary genes that stimulate the secretion of the ripening enzymes which catalyze reactions to change the properties of the fruit. Ethylene channelizes the action of several other chemicals called hydrolase, amylase, kinase, and pectinase. These enzymes convert starch to sugar, alter the cell walls to make them softer, neutralize acids and cause the fruit to emit an aroma.
Fermentation

Fermentation is the conversion of complex substances to simpler ones under anaerobic conditions. The specific product from fermentation is driven by the type of micro-organisms acting on the substance in which the fermentation occurs. The products of fermentation are alcohols or acids and the release of carbon dioxide.
For example, wine produced from fruit juice is an alcohol as a result of fermentation by yeast, whereas beer is the result of yeast fermentation of grain. Antibiotics are obtained through fermentation by molds and some bacteria. Yogurt, cheese, and vinegar are products of bacterial fermentation. Leavened bread is obtained by yeast fermentation.
Sunscreens

Sunscreens are a combination of organic and inorganic compounds. Inorganic chemicals, like titanium dioxide or zinc oxide, form a physical barrier that reflects or scatters UV waves. Organic components like octyl methoxycinnamate (OMC) or oxybenzone absorb UV rays and release their energy as heat. This protects our skin from sunburns and detrimental effects like cancer.
Nail Paint Removers

Nail paint consists of three types of ingredients – organic solvents and drying agents, thickeners and hardening agents, and coloring agents. The remover is actually an organic solvent that is used as an ingredient in nail paint which may be acetone or ethyl acetate.
So when you apply the remover you are just bringing it back to its original state. The solvent molecules get in between the chains of polymers and separate them, making it easy to wipe it off with a ball of cotton.
Static Shocks

All materials are made up of electrical charges in the atoms of the material. There are equal quantities of electrons (negative charges) and protons (positive charges) that try to balance each other in the universe. Friction between two materials causes these charges to redistribute. The electrons from one atom are transferred to the other.
As we know, like charges repel each other and unlike charges attract each other. Whenever you touch anything that is a good conductor of electricity, the transfer of the extra electrons that have accumulated takes place, and it gives you the static shock. For example, generally in winters, you get a shock when you get out of the car or when you touch the door knob or filing cabinet.
Your body itself is a huge chemical factory wherein one or the other chemical reaction takes place every moment. Most people detest chemistry because of long reactions and difficult chemical names that we see in our books. However, taking a practical approach to understanding this science, that we come across in our everyday life, will help you appreciate it even more.
