Interfacial Acid Sites‐Mediated ZnO‐Based Electrocatalysts for Sustainable Dual‐Pathway H2O2 Production and Rechargeable Zn‐H2O2 Electrochemical Cell

open access: yesAdvanced Materials, EarlyView.
In this work, a synergistic strategy introduces interfacial acid sites, oxygen vacancies, and built‐in electric field into ZnSe/ZnO heterojunction to optimize its electronic structure and electrode micro‐environment. This overcomes sluggish oxygen reduction reaction kinetics and low H2O2 selectivity, achieving record H2O2 productivity (754.4 M gcat−1 ...

Archaeological Data Concerning the History of the Evangelical Church in Dealu Frumos, Sibiu County

open access: yesMateriale și Cercetări Arheologice, 2011
Most historians agree that the original planimetry of the church in Dealu Frumos consisted of a hall church with nave and two aisles, a square choir, a semicircular apse and a western tower. All these were built during the 13th century, before the Tartar

High Center‐of‐Mass, Multi‐Legged Soft Robots Powered by Geometrically Encoded Liquid Crystal Elastomer Arc Appendages

open access: yesAdvanced Materials, EarlyView.
Inspired by the octopus and the golden wheel spider, soft robots with liquid crystal elastomer arc fibers as appendages are fabricated to transcend surface constraints through an elevated center of mass and minimal contact footprints. By leveraging curvature‐encoded deformation‐recovery cycles, these robots exhibit contractile, torsional, and flexural ...

From Behavior to Dynamics: Decoding Carrier Roles in Cu‐based Photocathodes for Solar‐Driven CO2 Reduction

open access: yesAdvanced Materials, EarlyView.
The performance of Cu‐based photocathodes in photoelectrochemical CO2 reduction is not governed by catalytic sites alone, but by the dynamic journey of photogenerated carriers. This review decodes how carrier generation, recombination, transport, accumulation, extraction, and electrolyte coupling shape catalytic activity, selectivity, and stability ...

The Mummy Trappings in the National Museum in Belgrade: A Reconstruction and Typological Assessment

open access: yesEtnoantropološki Problemi, 2019
In July 2009 the National Museum in Belgrade received – as a donation – two elements of a funerary assemblage: a fragmented mask and a conjoined collar-breast covering.

Reliable and Reusable All‐Solid‐State Contact‐Type Pre‐Lithiation Platform for High‐Performance All‐Solid‐State Batteries

open access: yesAdvanced Materials, EarlyView.
A reusable contact‐type pre‐lithiation platform enables uniform, precisely controllable pre‐lithiation at low stack pressure, suppressing interfacial degradation and thereby markedly improving initial Coulombic efficiency and cycling performance in all‐solid‐state batteries.

THE SURGICAL TREATMENT EFFECTIVENESS OF PATIENTS WITH MIDDLE EAR CANCER

open access: yesЮжно-Российский онкологический журнал, 2020
Among human malignant tumors, middle ear cancer is rare: up to 0.06%, and among ear tumors — up to 5%. Due to the late detection of the tumor, patients turn to a specialist with advanced, nearly or completely unresectable disease, and it limits the ...

Organic–Inorganic Hybrid Hole‐Selective Layer Interface Engineering for Enhanced Photoelectrochemical Water Oxidation on Bismuth Vanadate Photoanodes

open access: yesAdvanced Materials, EarlyView.
In this research the [4‐(3,6‐dimethyl‐9H‐carbazol‐9‐yl)butyl] phosphonic acid (Me‐4PACz) self‐assembled monolayers (SAMs) to bond with NiOx is first designed to be the organic‐inorganic hybrid hole‐selective layers, which promotes the BiVO4 photoanodes photoelectrochemical water splitting performance with 6.9 mA cm−2 photocurrent at 1.23 VRHE and at ...
