TOTAL ENERGY CALCULATION OF AlAs AND InAs BINARY SEMICONDUCTORS USING THE PROJECTOR AUGMENTED WAVE METHOD

The total energy of an element is the basic energy value from which other properties of the element can be calculated. Aluminum Arsenide (AlAs) and Indium Arsenide (InAs) are III – Arsenic binary semiconductors with indirect and direct energy band gap respectively. The total energy of each of them was calculated using the Projector Augmented Wave (PAW) method with the PBE-GGA for the exchange-correlation functional. The total energy were calculated and from the results gotten, the la...

Synthesis, Characterization of Acid Orange 7 Dye on Cellulose Acetate Biopolymer

ABSTRACTThe present paper describes the synthesis of Acid Orange(7)dye which can be used as dyes for cellulose acetate biopolymer. They were obtained by the diazotization of a monoazo component of the mono-azobenzene type, followed by coupling. The monoazo components were obtained by the diazotization of sulphanilic acid and coupling with 2-naphthol. The synthesized dye was later analyzed by GC-MS, IR and UV-Vis spectrometry. The dyeing performance of the dye was evaluated on cellulose acetat...

Evaluation of four baking temperature regimes and their effects on shelf stability of bread loaves

The work was done to determine the effects of baking temperature on the proximate, micronutrient, microbial and sensory properties of bread. The breads were baked at four different temperatures of 190, 200, 210 and 220 0C for BT1, BT2, BT3 and BT4 respectively. The protein ranged from 10.53% to 12.42% and a significant (p < 0.05) difference existed between the samples. The crude fibre ranged from 1.50% to 1.70% and a significant difference existed between samples BT1, BT2, BT3 and BT4. The fa...

Antimicrobial screening , nutrients profile and Pyhtochemical analysis of the leaf extracts of Tetrapluera tetraptera

ABSTRACTPhytochemical and Antimicrobial activity of the leaves of Tetrapluera tetraptera using aqueous and ethanolic extract was studied. The leave was observed to be highly rich in polyphenols, flavonoid, reducing compounds and alkaloids. Glycosides, saponins and tanins were present in small amount, there was absence of Phlobotanins, anthraquinones and hydroxyl methyl anthraquinones. In order to confirm the exact concentration of the Phytochemicals present in the leave of T. tetraptera, a GC...
