Essays on Chemical Reaction

Chemicals and Lipases All chemicals and solvents used were of analytical or chromatographic grade and purchased from SD Fine Chemicals (Mumbai, India). Lipozyme TL IM was obtained as gift from Novo Nordisk Ltd. (Bagsvaerd, Denmark). Soluble Thermomyces lanuginosus lipase [TLL] was purchased from DK Enzymes…

Antioxidants are quite common components that are essential for disease control. The main function of antioxidants is to reduce the free radical effect in body. Upon oxidation process in body, some natural products are formed known as free radicals that leads to damage of tissues,…

Introduction Water is a source of life and regarded as the most essential of natural resources. Increasing contamination of freshwater with thousands of industrial and natural chemicals is one of the key environmental problems in today’s world. Among other pollutants, the Persistent Organic Pollutants (POPs)…

The phenomenon of complex coacervation has been observed in a variety of complimentary polyelectrolyte systems [1-7]. Very often, associative interactions between oppositely charged polyelectrolytes lead to the formation of soluble interpolymer complexes which in turn coalesce to yield macroscopic coacervate droplets [8-12]. The coacervate material…

The effect of magnesium oxide (MgO) on the thermal conductivity reinforcement of silicone elastomers has not been extensively studied. Most of the previous works about thermal conductivity of MgO/polymer composites have focused on matrices with less viscosities like epoxy [1,2] and Poly methyl methacrylate (3)….

Introduction In surface chemistry, adsorption stands for the adhesion of chemical species onto the surface of particles. Adsorptions are usually done with the help of adsorbents. These adsorbent surface acts as an effective adsorptive sites that attracts pollutant ions to accommodate into the vacant sites….

This is a experiment to determine the identity of a unknown acid with a given base. To do this experiment an acid-base titration is required with the base being NaOH. This is a experiment that requires a burette to release allotted proportions of base into…

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…

Soil and groundwater contain a variety of chemical mixtures originating from the manufacturing industry of modern materials. Xenobiotics are defined as non-endogenous substances that can be found in an organism, for example, pesticides and environmental pollutions. The constant exposure to these xenobiotics poses a health…

In 1989, Robson introduced metal organic frameworks (MOFs) as a combination of transition metals and organic ligands cluster that are well-known for their highly porous structure, tunable architecture and high surface area. MOFs provide diverse applications in advanced chemistry such as catalysis, drug delivery, separation,…

Introduction Quantum dots are tiny particles or nanocrystals of a semiconducting materials with diameters in the range of 2-10 nanometer (10-50 atoms). As result of this phenomenon, quantum dots can emit any color of the light from the same materials simply by changing the dots…

PH meter is an electric contraption used to measure hydrogen-molecule development (sharpness or alkalinity) in course of action. On an exceptionally fundamental level, a pH meter contains a voltmeter associated with a pH-responsive cathode and a reference (unvarying) terminal. The pH-responsive terminal is for the…

INTRODUCTION There are various type of laundry detergent. Most older types of laundry detergent would use very strong soaps to wash away dirt, many of the more modern brands of detergent are trying ways that are more “green” for getting rid of stains. These detergents…

Getting recognized for awards has become a huge part of society and it has brought forth a huge cluster of academics, artists, scientists, humanitarians, and many more astounding individuals of invention and influence. The Nobel Peace Prize is a prime example of a prestigious award…

Recently, the researches and the applications of Crumb Rubber have shown a lot of benefits characteristic. The increased use of crumb rubber in flexible pavement requires a better understanding of its influence on the physical and rheological properties of rubber asphalt binder. According to Ibrahim…
