Requirement of Zn to demonstrate HCO3-stimulated ATPase activity of rat small intestinal brush border. [PDF]

open access: yes, 1979
The existence of a membrane-bound HCO3-stimulated ATPase in intestinal mucosa is controversial. A crude brush border fraction of rat small intestinal homogenates contained HCO3-ATPase activity which was inhibited by preincubation with 3 mM EDTA. Alkaline

Nano‐Oil‐Barrier‐Based Fluttering Triboelectric Nanogenerator

open access: yesAdvanced Science, EarlyView.
This work proposes a wind‐driven nano‐oil‐barrier‐based fluttering triboelectric nanogenerator (NF‐TENG). A nano‐oil barrier is a simple and innovative strategy to maintain a thin lubricant layer for long‐term cycling based on commercial oil‐absorbing sheets and oil‐infusion steps, which can improve both mechanical and electrical stability of TENGs ...

High‐Sensitivity Perovskite γ‐Ray Detectors Enhanced by Device Engineering Toward Energy Spectroscopy Imaging

open access: yesAdvanced Science, EarlyView.
Optimized electrode configuration in perovskite γ‐ray detectors achieves enhanced energy resolution from 7% to 1.9% by reshaping bias electric fields and reducing noise. A novel spectral‐enhanced imaging strategy is developed, utilizing spectral dimensions to improve image contrast and quality.
