Portable electrochemical synthesis of H2O2, which is widely used for disinfection, sterilization, and waste treatment, has attracted increasing attention. However, low atomic utilization efficiency by-product disposal during the electrocatalysts are inevitable. Based on advantages single-atom catalysts (SACs) towards H2O2 via a 2e− transfer oxygen reduction reaction, this work presents ZnNC SAC...

Singe-atom catalysts (SACs), as heterogeneous catalysts, have attracted increasing attention in recent years owing to their numerous advantages the field of electrocatalysis, such a high atom-utilization rate and unique structural characteristics. In this review, we introduce various preparation methods for obtaining SACs based on top-down bottom-up synthesis strategies corresponding research p...

The acoustic properties of natural fiber-reinforced composites should be identified before using these materials in various engineering applications including sound and vibration isolation. This study investigates the effects sample thickness fiber/resin ratio on performance jute luffa biocomposites. For this purpose, composite samples with different thicknesses fiber/epoxy ratios are manufactu...

This perspective outlines recent advances, future opportunities and challenges in the research field of single-atom-based catalysts (SACs) photoelectrocatalytic (PEC) system.

Background and Aims Apomixis, or asexual seed formation, in polyploid Hieracium subgenus Pilosella species results in clonal progeny with a maternal genotype. An aposporous embryo sac forms mitotically from a somatic cell, without prior meiosis, while embryo and endosperm formation is fertilization independent (autonomous). The latter two developmental components are tightly linked in Hieracium...

Stretch-activated channels (SACs) have been found in smooth muscle and are thought to be involved in myogenic responses. Although SACs have been shown to be Ca(2+) permeable when Ca(2+) is the only charge carrier, it has not been clearly demonstrated that significant Ca(2+) passes through SACs in physiological solutions. By imaging at high temporal and spatial resolution the single-channel Ca(2...

Stretch-activated channels (SACs) have been considered as one of the possible modulators on the mechanisms of mechano-electrical feedback (MEF) in the heart. With the abilities to modulate action potential duration (APD) during the systolic period and to trigger action potentials directly by diastolic stretch, SACs could play an important role on stretch-induced arrhythmias. The objective of th...

Neural circuits rely upon a precise wiring of their component neurons to perform meaningful computations. To compute the direction of motion in the visual scene, the direction selective circuit in the mouse retina depends on an asymmetry in the inhibitory neurotransmission from starburst amacrine cells (SACs) to direction selective ganglion cells (DSGCs). Specifically, depolarization of a SAC o...

Sanarelli (1891) is believed to have been the first to employ collodion sacs in animal experimentation. Subsequently, sacs of different types have been used in various in vivo experiments by a number of investigators (see bibliography). Alcohol-ether collodion was employed in each case for the preparation of the semipermeable membranes. In order to withstand the distorting effect of the intesti...
