profits. A bare minimum wage plan was agreed upon in various companies so that the workers could be assured of at least a decent minimum pay. Workers were offered a better safety package so that they could be kept away from harmful chemicals and reagents. A medical plan was constituted to look into medical problems and the internal quality of the factories was made to suit internationally accepted health standards. This meant that the on-site hazards to the workers could be reduced to a great…

The following safety rules must be observed while performing any of the scheduled laboratory experiments in one of the Chemistry Laboratories. [1] Students who are found in violation of the safety rules will be given a warning for the first offense, will be dismissed from the lab room for the second offense, and will be withdrawn from the lab for the third offense. If a violation is observed at a particular lab table such as spilled liquid - water or hydrochloric acid and those working at that…

Abstract: We describe the successful synthesis of Polypyrrole-Gold nanocomposites (PPy-Au NCs) by the chemical oxidative polymerization of pyrrole with ferric chloride as an oxidizing agent, in the presence of a colloidal suspension of gold nanoparticles. Gold nanoparticles (Au NPs) were synthesized by standard citrate reduction method. Au NPs and PPy-Au NCs were characterized by Transmission Electron Microscopy (TEM), Atomic Forced Microscopy (AFM), Scanning Electron Microscopy (SEM), Fourier…

of the calibration curve (of the analyte) f) Ruggedness Method ruggedness is defined as the reproducibility of results when the method is performed under actual use includes different analysts, laboratories, columns, instruments, sources of reagents, chemicals, solvents and so on. Method ruggedness may not be known when a method is first developed, but insight is obtained during subsequent use of that method. Results and Discussion Chromatogram of DAPA and SAXA Got chromatogram at RT’s…

Dalise Atwell BIO 212 Dr. Boles Excelsior College Penicillin and its Impact on Microbiology Penicillin has saved many lives past and current. “Before the discovery and use of penicillin, infectious diseases had been the leading cause of death throughout history. Furthermore, the therapeutic tools available for treating infections were few and of limited use.”(Kardos 2011) Penicillin has been the drug of choice when treating many diseases. Even though there are people allergic to…

byproduct of this reaction are easily recyclable substances.5 This correlates to another major principle of green chemistry: the use of renewable raw materials. Rather than forming unusable waste products, both substances can potentially be used as reagents in future experiment or they can be easily converted into other practical substances. Results Clay-catalyzed dehydration of cyclohexanol The product collected from the first experiment was a colorless low viscosity liquid. The…

Mystery Creek Resources, Inc. (MCRI), a wholly-owned subsidiary of Fire River Gold Corporation, proposes to continue to operate, reclaim, and close an underground precious metal mine and associated mill known as the Nixon Fork Mine Project (Project). The Project is located approximately 32 miles northeast of McGrath and eight miles north of Medfra in west-central Alaska (Figure 1; see Appendix A for report figures). The Project is not connected with the Alaska road system; therefore site access…

Genetically modified organisms also known as GMOs have been an area of hot debate over the last few years. In this article we will explore the arguments for and against GMOs and at the end dispel the fear-mongering and show that humanity has been modified organisms since the beginning of recorded human history; we are just much better and faster at it now than in the past 1,000s years. The goal in GMOs is to modify organisms (generally food stock such as livestock and extensive agriculture,…

phase synthetic routes to semiconductor materials, such as chemical vapour deposition (CVD), molecular beam epitaxy (MBE) and spray pyrolysis. Factors such as control of film thickness and deposition rate by varying the solution pH, temperature and reagent concentration are allied with the ability of chemical bath deposition to coat large areas, in a reproducible and low cost process. The chemical bath deposition process uses a controlled chemical reaction to effect the deposition of a thin film…
