Camphor is a ketone. In the experiment we also need to determine the purity of the product. Ketones can be oxidized from a secondary alcohol using a strong oxidizing agent such as chromic acid. However, there exists chromium compounds that are known to be corrosive and generally harmful and pose as a legal disposal issue due to their harmful nature. Chromic acid cleanly oxidizes secondary alcohols to ketones using acetones as solvent and the product isolation is simple.
Nearest example is automobile exhaust and emission from the factories. In meanwhile, the formation of nitrogen oxide gasses (NOx) and volatile organic compound (VOC) from the combustion of gasoline and coal is released into the air. In the sunny day, NOx and VOC are likely to combine with oxygen and formed ozone, O3. This level of ozone is high toxic and corrosive to living system. Some negative side effect with people who inhale ozone during highly exposed may result respiratory infection or lung damage.
Photochemical Oxidation: The photochemical technologies present the advantages to be simple, clean, relatively inexpensive, and generally more efficient than chemical AOPs. Also, they can disinfect waters, and destroy pollutants. Consequently, UV radiations have been coupled with powerful oxidants such as O3 and H2O2, including, in some cases, a catalysis with Fe3+ or TiO2, resulting in various kinds of important photochemical AOPs. These photochemical processes are able to degrade pollutants by means of three possible reactions, including photodecomposition, based on UV irradiation, excitation and degradation of pollutant molecules, oxidation by direct action of O3 and H2O2, and oxidation by photocatalysis (with Fe3+ or TiO2), inducing the
However, it can be very reactive when it is combined with other elements, such as hydrogen (H) in ammonia (NH3). This is done by the Haber process, in which nitrogen from the air is combined with hydrogen derived from natural gases into ammonia. It is known the be the most common chemical bond in the chemical industry. Nitrogen is part of many significant compounds, such as nitrous oxide, nitroglycerin, nitric acid and ammonia. The triple bond of nitrogen forms with other nitrogen atoms in which creates an extremely strong bond and releases a considerable amount of energy when the said bond is broken, which is why nitrogen is valuable when it comes to explosives.
Upgrading Your Steam Pot Steaming, one of the widely used parts of skincare routine hardly requires any efforts. All it literally need is water, a pot, and appropriate heat. And, if included some additional natural herbs, it becomes more special and highly beneficial. After all, what else can be better than natural methods with no side effects for treatment! “An herbal facial steam allows its special properties to treat all types of skin problems by cleaning the debris from pores,” says Rajesh Phaiju, Spa specialist at Tranquility Spa.
The chromium can form a passivation (oxide film) and obstruct the diffusion of the oxygen from surface to the internal structure. Also, the composition of Nickel (Ni) will corporate with chromium and increase the ability of corrosion resistant of stainless steel. For the physical properties of stainless steel, the strength of stainless steel is much higher than iron. The high strength of stainless steel is due to the low carbon content. The carbon atom can block the dislocation and prevent the deformation of the material.
Chlorine is able to kill pathogens and microorganisms by destroying their cellular structure. However, one disadvantage of this method is that residual chlorine in water is harmful to useful aquatic life. • Ozone In this method, ozone is produced by exposing oxygen to high voltages. Ozone is very effective when killing pathogens and it decomposes back to oxygen. However, one disadvantage of this method is that it uses a lot of energy which translates to a higher
Tea Tree essential oil: As potent as chemical compounds such as benzoyl peroxide and salicylic acid in controlling acne, tea tree essential oil is one of the most powerful natural astringents and purifying agents. It kills the microorganisms that cause acne and balances the secretion of sebum. Tamanu oil: Whether you are dealing with scars, signs of aging, hyper pigmentation, rash or sores, tamanu oil will prove to be the perfect solution for all your skin woes. This essential oil has long been used in skin care preparations because it promotes cellular growth and is a powerful antioxidant. So, it can be used to deal with age related skin issues as well as scars and skin
Cornu and Hatley first described the unique role of these molecules in absorption of ultraviolet light. In addition, the ozone layer was first discovered in 1913 by Charles Fabry and Henry Buisson (Solomon, 1999) however, the properties was first described by Dobson who invented a simple spectrophotometer that could measure the stratospheric ozone from the ground (Sivasakthivel, 2011). Ozone layer is very important for the earth in such it absorbs about 93% up to 99% of the high frequency radiations. In today’s condition, the earth is suffering a drastic depletion of this layer due to excessive release of pollutants containing chlorine and bromine gasses of chlorofluorocarbons (CFCs) and halons (Solomon, 1999). Recent studies states that these deteriorations let extra UV-B radiation to reach the earth’s surface that inhibits the reproduction of phytoplankton, organisms that make up the base of food chain.
Blog 1.Clean means healthy: Why is it important to keep your rear clean Nature has equipped us quite nicely with a smooth skin; only tender parts covered with hair to protect them from dirt, dust, and insects. It was working very well till the very moment when we invented clothes. Nowadays panties are giving our buttocks protection against external threats, and we don’t need hair any more. But it is still there, hampering our efforts to stay clean; that leads to an unpleasant smell, and, what is way more important, this can be a reason for an irritation, chafing, and itching. When we talk about the importance of maintaining intimate hygiene, we must remember to keep all our intimate parts clean during the day, no matter where we are: at home, in the office, or on the road.
