Transition metal carbides and nitrides are interesting non-precious materials that have been shown to replace or reduce the loading of precious metals for catalyzing several important electrochemical reactions. The purpose of this review is to summarize density functional theory (DFT) studies, describe reaction pathways, identify activity and selectivity descriptors, and present a future outlook in designing carbide and nitride catalysts for the hydrogen evolution reaction (HER), oxygen evolution reaction (OER), oxygen reduction reaction (ORR), nitrogen reduction reaction (NRR), CO reduction reaction (CORR) and alcohol oxidation reactions. This topic is of high interest to scientific communities working in the field of electrocatalysis and this review should provide theoretical guidance for the rational design of improved carbide and nitride electrocatalysts.

Iodine staining with distance countdown improving the safety for reduction of adverse events: a randomized controlled trial.

Background: Lugol's chromoendoscopy (LCE) is valuable, cost-effective, and widely used in early esophageal cancer (EEC) screening, yet it suffers from low compliance due to adverse events after LCE. In addition, the reflux of iodine during iodine staining in the upper esophagus brings the risk of bucking and aspiration. We introduced a new model called distance countdown (DC) aimed to reduce reflux during iodine staining in upper esophageal LCE.

Unlabelled: Despite the prevalence and severity of enterococcal bacteremia (EcB), the mechanisms underlying systemic host responses to the disease remain unclear. Here, we present an extensive study that profiles molecular differences in plasma from EcB patients using an unbiased multi-omics approach. We performed shotgun proteomics and metabolomics on 105 plasma samples, including those from EcB patients and healthy volunteers.

Despite the first examples being isolated more than two decades ago, little is known about the redox chemistry of stable phosphacyclic biradicaloids. Here, we demonstrate that a biradicaloid featuring a diphosphaindenyl backbone is able to undergo both oxidation and reduction reactions. One-electron oxidation results in the formation of a dicationic cage compound structurally related to an isomer of hypostrophene (CH).

Objective: Anorexia nervosa (AN) is an eating disorder characterized by severe weight loss and associated with hyperactivity and circadian rhythm disruption. However, the cellular basis of circadian rhythm disruption is poorly understood. Glial cells in the suprachiasmatic nucleus (SCN), the principal circadian pacemaker, are involved in regulating circadian rhythms.

Fe-N-C catalyst is the most promising alternative to platinum catalyst for proton-exchange membrane fuel cells (PEMFCs), however its high performance cannot be maintained for a long enough time in device. The construction of a new Fe coordination environment that is different from the square-planar Fe-N 4 configuration in Fe-N-C catalyst is expected to break current stability limits, which however remains unexplored. Here, we report the conversion of Fe-N-C to a new FeNxSey catalyst, where the Fe sites are three-dimensionally (3D) co-coordinated by N and Se atoms.
