Discovery and Characterization of Novel Esterases with Ethyl Carbamate-Hydrolyzing Activity by LIU Qingtao, ZHU Sibao, WANG Tianwen, LI Chuang, QIAN Senhe, ZHANG Wenqing, CHENG Fan, TIAN Shufang

“…Structural analysis indicated that the narrow substrate channel of ES9 might affect the entry of EC, thus affecting its maximum reaction rate (Vmax) toward EC; the relatively high affinity of ES9 for EC might be attributed to the strong hydrogen bonding between them. The EC-degrading esterases had good ethanol tolerance, which not only enrich the EC-hydrolyzing enzyme library, but also provide a new method for controlling the EC content in traditional fermented foods with low alcohol content.…”

Determination of the degree of sulfonation in cross-linked and non-cross-linked Poly(ether ether ketone) using different analytical techniques by Abdul G. Al Lafi, Mohammed S. Rihawy, Abdul W. Allaf, Ali Alzier, Reem Hasan

“…Classical approaches, such as titration and back titration are suitable for all sulfonated samples; however, they are limited by challenges like the extended time required for neutralization reaction due to hydrogen bonding between sulfonic acid groups. In contrast, molecular spectroscopic methods particularly UV and 1H NMR spectroscopy, are more efficient for soluble samples. 1H NMR spectroscopy is especially accurate, though it necessities additional steps, such as determining T1 relaxation times to ensure complete magnetization recovery. …”
