The structural properties of 4-substituted phenols capable of proton-coupled electron transfer (PCET) to superoxide (O2 ) were investigated on the basis of electrochemical and electron spin resonance (ESR) spectral measurements and supported by density functional theory calculations. Although the proton and electron donating abilities of phenols are considered to be important factors in PCET re...
Naturally occurring selenium compounds like selenite and selenodiglutathione are metabolized to selenide in plants and animals. This highly reactive form of selenium can undergo methylation and form monomethylated and multimethylated species. These redox active selenium metabolites are of particular biological and pharmacological interest since they are potent inducers of apoptosis in cancer ce...
Students’ performance in chemistry examinations Nigerian secondary schools is consistently low. Factors attributed to students' low include interest the subject, abstract and complex nature of concepts, dominant use teacher-centered methods. Thus, need for a novel strategy that has potential improve present concepts more explicitly. This study aimed examine method incorporated advance organizer...
The conversion of pentoses to ethanol is one of the major barriers of industrializing lignocellulosic ethanol processes. As the most promising native strain for pentoses fermentation, Pichia stipitis has been widely studied for its xylose fermentation. In spite of the abundant experimental evidence regarding ethanol and by-products production under various aeration conditions, the mathematical ...
