ABSTRACT Solubility is the phenomenon of dissolution of solid in liquid phase to give a homogenous system.Solubility is one of the important parameter to achieve desired concentration of drug in systemic circulation for pharmacological response to be shown. Poor watersolubledrugs often require high doses in order to reach therapeutic plasma concentrations after oral administration. Low aqueoussolubility is the major problem encountered with formulation development of new chemical entities. Any…

With the improvements in recycling techniques, energy-efficient appliances, and cars it would be a selfish act to not get involved in this movement. Consumers are consistently trying to find new and improved ways to lessen the effects of pollution through automobiles, and the preservation of energy through more effect energy appliances. It is our responsibility as a society to improve our environment and eliminate as many harmful wastes as we can. “Americans generate about 250 million tons…

The goal of this experiment was to use the technique of thin layer chromatography (TLC) to identify the active analgesic ingredient of Advil and monitor the transesterification of methyl salicylate from acetylsalicylic acid. The synthesized methyl salicylate was then purified using acid-base chemistry and analyzed using H NMR spectroscopy. Identification of a proper mobile phase to separate common analgesics used in over-the-counter pain relievers was essential in being able to determine the…

CHEM 8 A Stereochemistry Report Scaffold Introduction The purpose of this experiment was to find out the absolute configuration of 1-phenylethanol. This was accomplished by using the method of competitive enantioselective conversion (CEC), where 1-phenylethanol reacts with one enantiomer of the chiral catalyst homobenzotetramisole (HBTM). The technique that was applied was thin-layer chromatography (TLC), which will determine the HBTM enantiomer that will react faster. Theory The difference…

Localization of Antidiabetic Potential of Cassia Tora Linn. Seeds Abstract Cassia tora Linn. is the wild medicinal plant and grows in most parts of India as weeds. In traditional literature, it is found that seeds of Cassia tora Linn. were used as folk medicine for the treatment of Diabetes in different parts of the world. In preliminary phytochemical investigations methanolic extract showed positive tests to sterols, carbohydrates, flavanoids, phenolic compounds, saponins and anthraquinine…

4.2.1. Material: Lead zirconate titanate (PZT) PZT is a short for lead zirconate titanate inorganic compound that has a chemical formula of Pb [ZrxTi1-x] O3 (0 ≤ x ≤ 1). PZT is made and composed of the two chemical elements lead and zirconium combined with the chemical compound titanate while formed under extremely high temperatures. The dielectric constant of PZT can range from 300 to 3850, depending upon orientation and doping. PZT possesses piezoelectric effect meaning that it changes shape…

To clean the wells, we used diluted 7X detergent, we rinsed them with high purity water and methanol, blotted them dry with lens paper. The wells were then assembled by sticking and removing a piece of scotch tape from each face of the well and then sticking the well to glass coverslips. While the wells were being cleaned and assembled the dilution…

Agree or disagree with the proposition that our national water supply is safe. Use one short quote from Joy Horowitz's "Parkinson's Alley" as one means of development and support in your essay. Your name Professor 23 April 2016 Water is a vital element in the life of every human being. Not only is it essential to our health, but also for use in numerous household tasks. Everyday water is used for cooking, bathing, cleaning, and drinking. It is therefore necessary to consider the safety of…

Question 5 Apex Healthcare Berhad The sustainability disclosure made on the company’s website is disclosed the same information with the disclosure made in the annual report 2014. While, there are something difference between the sustainability disclosures made on the company’s website and the annual report 2013. In the annual report 2013, Apex Healthcare Berhad does not organized the “gotong- royong” sessions in schools, which will help and support them to fight against dengue menace. They…

their higher viscosity, acidity levels that influences the structural integrity of the engine and low density which results in low calorific value and leading to incomplete combustion. In this process, in the presence of Sodium hydroxide catalyst and methanol batch transesterfication is applied to sunflower oil for the production of biodiesel. The biodiesel was characterized and then conducted using Nuclear Magnetic Resonance (NMR), bomb calorimetry, sulphur content tests and Gas Chromatography…
