A Nanostructured Ru‐Mn‐Nb Alloy with Oxygen‐Enriched Boundaries for Ampere‐Level Hydrogen Evolution

open access: yesAdvanced Science, EarlyView.
Ru62Mn12Nb21O5 medium‐entropy alloy with a crystal‐crystal dual‐phase structure is deposited on a carbon cloth substrate by the magnetron sputtering method. The oxygen‐rich interface induced by the rich Mn phase and the poor Mn phase optimized the electronic structure of the catalyst, adjusted the adsorption and desorption processes of intermediates ...

Reductive Supramolecular In Situ Construction of Nano‐Platinum Effectively Couples Cathodic Hydrogen Evolution and Anodic Alcohol Oxidation

open access: yesAdvanced Science, EarlyView.
The supramolecular framework reductant is developed to realize the in situ construction of highly dispersed ultrafine nano‐Pt. The nano‐Pt supported on the BCN carrier realizes multi‐scenario electrocatalytic water hydrogen production, and establish a high‐performance cathode hydrogen evolution‐anode methanol oxidation coupling system, presenting a low‐

CCDC80 Protects against Aortic Dissection and Rupture by Maintaining the Contractile Smooth Muscle Cell Phenotype

open access: yesAdvanced Science, EarlyView.
Aortic dissection (AD) is accompanied by a decrease in CCDC80 in vascular smooth muscle cells (VSMCs). CCDC80 can interact with JAK2, and VSMC‐specific CCDC80 deficiency accelerates the progression of AD by activating the JAK2/STAT3 pathway involved in regulating the phenotype switching and function of VSMCs.
