The band gap value of the DBAP molecule was calculated as 5.60 eV‚ which indicates that the DBAP molecule has stable molecular structure and the value is comparable with the band gap energy value of the reported bio-active molecules [16]. The higher hardness and lower softness value indicates the stability of the DBAP molecule. The obtained lower chemical potential and electrophilicity index values are comparable with the potential bioactive molecules [14‚ 16]. DOS spectrum was also simulated by

Pregnant women that smoke cigarettes on a daily basis can greatly harm their fetus. The Tobacco smoke in cigarettes greatly reduces fetal growth through the presence of nicotine‚ carbon monoxide‚ hydrogen cyanide‚ cadmium and various other aromatic hydrocarbons‚ but the two most dangerous chemicals that are found in cigarettes are nicotine and carbon monoxide. Nicotine causes the babies heart rate to speed up‚ reduces placental vascularisation‚ constricts the placental arteries‚ and thickens the

SUBJECT: CLINICAL CHEMISTRY TITLE: TOTAL BILIRUBIN & DIRECT BILIRUBIN LABORATORY: 19 & 20 INTENDED USE: 1. For the quantitative determination of total bilirubin in serum 2. For the quantitative determination of direct bilirubin in serum INTRODUCTION: One part of bile is a yellow (or brownish) substance called bilirubin. Bilirubin starts out as a product of the breakdown of red blood cells. When red blood cells break down‚ the heme molecule is converted into bilirubin

long as the difference of their pKa or pKb constants is large enough. In this experiment‚ we would like to carry out the extraction to extract out the benzoic acid p-dichlorobenzene. Benzoic acid is a colourless crystalline solid and the simplest aromatic carboxylic acid. While‚ the d-dichlorobenzene is an organic compound which is colourless. Its melting point is in the range of 52-54 °C Experimental procedure 1. 40ml of dichloromethane with contain 1g of p-dichlorobenzene and 1g of benzoic acid

Preparation of an Alkene by dehydration of an alcohol in the presence of a catalyst. Calculate the percentage recovery of products. Test for purity and identification of products. Abstract Cyclohexene and cyclohexanol are both colourless aromatic compounds. The major difference between the two is the presence of the hydroxyl group present in cyclohexanol. This hydroxyl group can be removed by a process known as dehydration which results in the production of cyclohexene at the end of the dehydration
