Carbon dioxide It reacts with alkali to produce carbonates and It is soluble in water and it is colourless gas. Carbon dioxide is used to produce soft drinks and soda water.Carbon dioxide is used for to prevent fungal also Carbon dioxide doesn’t react with acid…
At an A-Level Biology taster course I was introduced to genetic fingerprinting and partook in an experiment using gel electrophoresis. Watching different DNA fragments travel to the cathode at different distances, I saw the similarity with electrolysis, a concept I was familiar with from Chemistry….
Introduction Cosmetics and perfumes, sometimes viewed as the savior of women and recently men too. A person beautifying their outward appearance has been a tradition in the world since ancient times. Whether it may be a new hair dye, a newly bought fragrance, or a…
The use of hydrogen peroxide (H2O2) as an environmentally friendly oxidant for organic compounds has gained industrial importance since it offers the advantages of simple process, easy work-up, low cost and reduction in noxious waste materials. Hydrogen peroxide is a clean and effective oxidizing agent…
Theoretical Background Thousands of years ago, burying wastes have already been an effective way in helping the environment. However, because of the increase in population in the present time, digging a hole is not enough. With the larger number of human population, equates larger amount…
The somewhat enjoyable smell of recently purchased vehicles can be described as oddly satisfying for the majority of buyers, but where does this odour come from? With the production of vehicles, comes a wide variety of long, hard to pronounce chemicals that don’t appear to…
Everything from our plastic water bottles and cosmetics to our non-stick frying pans contains chemicals that accumulate in our bodies. From furniture to food containers, our lives are filled with chemicals, many of which may be hazardous to our health. Some of these substances can…
A hydrated iron(III) fluoride (FeF3. 0.33 H2O) and hydrated multi-walled carbon nanotubes- iron(III) fluoride (MWCNT-FeF3.0.33 H2O) composites were prepared by a simple two-step method. Firstly, a wet chemistry reaction between iron(III) nitrate nonahydrate (Fe(NO3)3*9H2O) and ammonium fluoride (NH4F). The thermal decomposition of the mixture in…
Cashew nut shell is a waste from cashew nut industry. It contains liquid known as Cashew Nut Shell Liquid (CNSL) which has similar molecule structure with synthetic phenol Phenol is a material for phenolic resin in preparation of varnish. The aims of this research are…
Recently, graphitic carbon nitride (g-CN), a metal-free polymeric semiconductor with visible light activated band gap (2.70 eV) has been proposed as photocatalyst in the applications involving water splitting and decomposition of organic pollutants for advantages of earth abundance, appropriate reduction potential, exceptional physical properties, unique…
An isotope is a form of a chemical element that contains the same number of protons but different amount of neutrons, which are located in the nucleus telling us that their atomic number and their chemical properties stays the same, but it affects their relative…
In this chapter a series of electrochemically oxidized CF samples are produced using a commercial grade PAN precursor fibre and characterized using SEM, XPS, FT-IR and Raman spectroscopy. The application of the Raman spectroscopic techniques developed and demonstrated through the previous chapters, namely mapping and…
Polyoxometalates (POMs) display a well explored area of inorganic metal oxide-derived materials, and they have shown potential for applications in the areas of electrochemistry, catalysis, magnetism, medicine, materials design(Jacks32). POMs, isopoly[MmOy]p- and heteropolyanions [XxMmOy]q- are inorganic metal‐oxide cluster materials with a large diversity in geometrical…
While it is for the most part concurred that ethanol has a higher-octane number than gas, the correct octane numbers for various mixes of gas and ethanol are conflicting in the writing. The trouble in deciding the genuine octane numbers is ascribed to the impediments…
