Chemistry Essay

Aluminum
There are many chemical reactions in which aluminum can be used as a catalyst due to its reactive nature. Moreover aluminum has found its applications in various chemical industries.Aluminum is classified as a metal which is very lightweight. The ductility of aluminum lies midway between irons and copper. It can be easily molded into different shapes. The physical appearance of aluminum is very pleasant, varying from shiny gray or silver to dull gray. This why well polished and sometimes

Analysis & Quality
Fifield & Kealy (2000,p524) point out that a typical analytical laboratory carries out development and day-to-day application of analytical methods in optimum conditions. According to them, the successful functioning of activities in an analytical laboratory necessitates simultaneous management of a number of related but different operations. Reproducibility, reliability and efficiency of operation of various instruments are as much necessary as are collation and interpretation of data which

Advanced Analytical Methodology Problem Solving Assessment
Mass spectrometers measure the mass/charge ratio (m/z) of analytes. Mass spectrometry and MS/MS is applied in protein study as it makes use of the large array of genome and protein data stored in databases. The lists of peak intensities and mass-to-charge (m/z) values produced by a mass spectrometer can be processed and compared with lists generated from the theoretical digestion of a protein or the theoretical fragmentation of a peptide.Mass spectroscopy makes use of the fact that many protein

Acid-Base Reactions &Water, Water Everywhere but Not a Drop to Drink
As such, a base is a substance, which in aqueous solution, becomes slippery, tastes bitter, and even changes color of litmus indicators. This is a suitable definition since it means a pH values ranging between 0 - 14, which for acidic solutions is pH < 7 while for basic solutions is pH > 7.The reason why today`s chemists use the term "base" as an alternative to "alkali" is that the alkali has a restricted meaning since all alkalies are bases while not all bases can be alkalies. Examples are

Antibacterial and biomedical applications of gold nanoparticles and graphene composite
(2010), Gold can be used in various fields of medicine, biotechnology, and catalysis. This makes it one of the most important subjects in the study of nanoscale materials. Gold nanoparticles are prepared using various processing routes like chemical, sonochemical and photochemical paths. However it is mainly made through the precipitation of the GNP in aqueous solution from dissolved gold precursors like HAuCL4 using reducing agents like sodium citrate, ascorbic acid, sodium boron hydride or

Care should be observed to avoid inhalation of the fumes during the collection and analysis process.Urine collection methods vary depending on the analyte being tested. Drugs differ in the way in which they are metabolized in the body, including the components that are excreted through the urine. Depending on the analyte being investigated, urine samples can be collected during different times to minimise interference. Analysis of urine samples is usually done using the high-performance liquid
