Comparative Study of Dextrose Production from Locally Sourced Cassava, Tigernut and Yam
Abstract: Starch was extracted after sedimentation from seven samples, TME 419, TMS 30572, Provitamin, Tigernut, Boko, Mumuyi and Onitsha. The first three samples were cassava varieties while the last three samples were species of yam variety Dioscorea rotundata. The extracted starch were gelatinized and hydrolyzed enzymatically to produce 250ml of dextrose from each sample. From spectrometer analysis it showed that Mumuyi dextrose has the highest glucose concentration of 0.72mg/ml when compared …

DFT studies of the structural, electronic and optical properties of armchair CaONT, Oxygen incorporated CaO2NT and CaO3NT and zigzag SWCaONT for Optoelectronics Applications
Abstract: In this research, the structural, electronic and optical properties of the nanotubes of CaO, CaO2 and CaO3 were studied using the DFT quantum computational approach. Although studies of electronic and optical properties were done for 2D CaO nano sheets with oxygen incorporation, there are no available data to show similar studies on the nanotubes forms of this metal oxide. This research therefore tried to explore more about the structural, electronic …
