A Hybrid Solid‐State Battery with a Panoramic‐Scale Stack of Bulk Electrodes and a Thin‐Film Electrolyte

Small, EarlyView.
A hybrid all‐solid‐state battery (ASSB) is implemented by integrating a thin‐film electrolyte on a bulk anode, and a thick cathode sheet. A densified anode substrate with suppressed porosity is prepared by cold pressing. Thin‐film electrolyte is fabricated onto the bulk substrate via co‐sputtering and infrared‐based rapid annealing.

Suppress Ru Over‐Oxidation Through Oxygen Vacancy Engineering – Showcase With Ni‐Modified RuO2 via Molten‐Salt Synthesis

Small, EarlyView.
Competitive OER catalyst for H2O splitting without using Ir is a luxury wish; Ru is an active element to do the job but often does not hold long. See how those scientists managed the task with Ni modified RuO2 suppressing Ru over‐oxidation through Oxygen Vacancy Engineering.

Oxophilic Yb2O3 nanoparticles as radical scavengers to enhance the durability of Fe–N–C oxygen reduction catalysts

Smart Molecules, EarlyView.
Fe–N–C catalysts suffer from radical attack during oxygen reduction. By immobilizing oxophilic Yb2O3 nanoparticles near Fe–N4 sites as efficient radical scavengers, the catalyst achieves enhanced activity and stability. Abstract The practical application of Fe–N–C catalysts in proton exchange membrane fuel cells is substantially limited by their ...

High‐Resolution Mapping of Discharge Product in Li─O2 Batteries

Small Methods, EarlyView.
Li─O2 batteries promise exceptional energy density, but have several factors limiting performance, such as poor rate performance. To understand rate limitations, scanning electron microscopy with energy dispersive X‐ray spectroscopy and X‐ray nano‐computed tomography were employed to map the distribution of discharge products in discharged air ...

Attenuated selective attention during visual perspective taking in autism: A combined behavior, ERP, and pupillometry study

Journal of Child Psychology and Psychiatry, EarlyView.
Background Altered social cognition in autism may be influenced by difficulties in domain‐general functions, such as selective attention. Here, we manipulated the requirement for selective attention during a visual perspective taking (VPT) task and used neurophysiological indices to delineate underlying mechanisms.

High‐Concentration Hydrogen Peroxide Gels Containing Calcium Polyphosphate Associated With Violet Led Light: Bleaching Efficacy and Effects on Enamel Properties

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objectives To evaluate the effect of violet LED light (VL) and hydrogen peroxide (HP) in‐office bleaching gels supplemented with calcium polyphosphate (CaPP) or calcium gluconate (GU): Materials and Methods Bovine enamel blocks (n = 10) were randomly assigned: commercial HP gel, commercial HP gel with GU, or experimental 35% HP with or without
