Synthesis of Bulk Superconducting LiNbO2 Crystals Through CaH2 Reduction

open access: yesAdvanced Materials, EarlyView.
CaH2 reduction reconstructively transforms insulating LiNbO3 single crystals into superconducting bulk LiNbO2 with a critical temperature of Tc = 14.4 K. Scanning electron microscopy reveals large‐volume, high‐yield phase conversion. Magnetization measurements demonstrate a robust ∼ 77% Meissner shielding fraction, establishing bulk superconductivity ...

ZrCo3B2 and HfCo3B2 Electrodes Go on Stage for Oxygen Evolution Reaction

open access: yesAdvanced Science, EarlyView.
The intermetallic compounds ZrCo3B2 and HfCo3B2 with distinctive chemical bonding features are excellent OER precursors, restructuring into OER‐active electrocatalysts delivering significantly high OER activities compared to the elemental Co, which is obvious from their lower onset potentials and increased obtained current densities.

Rapid Cooling After Device Annealing Suppresses Interface Losses in Cu2ZnSnS4 Solar Cells Enabling High Efficiency and Stability

open access: yesAdvanced Science, EarlyView.
Rapid cooling after device annealing regulates the CdS/CZTS heterojunction and Mo/CZTS back contact, suppressing interfacial recombination and modifying the interfacial MoS2 layer, thereby enabling a 15.9% indoor PCE in pure‐sulfide CZTS solar cells.

Terahertz Channel Modeling, Estimation and Localization in RIS‐Assisted Systems

open access: yesAdvanced Electronic Materials, EarlyView.
Reconfigurable intelligent surfaces have become a recent intensive research focus. Based on practical applications, channel strategies for RIS‐assisted terahertz wireless communication systems are categorized into three different types: channel modeling, channel estimation, and channel localization.

Beyond Charge: Field‐Effect Transistors in Multimodal Biosensing Platforms for Biomolecular Interaction Studies

open access: yesAdvanced Electronic Materials, EarlyView.
This review summarizes the developments in field‐effect transistor (FET)‐based dual‐mode sensor platforms and what can be learned from them. It identifies charge as a crucial factor in biomolecular interactions at interfaces, outlines the challenges of hybrid systems, and highlights their benefits.

Extended prone positioning for intubated ARDS: a review

open access: yesCritical Care, 2023
During the COVID-19 pandemic, several centers had independently reported extending prone positioning beyond 24 h. Most of these centers reported maintaining patients in prone position until significant clinical improvement was achieved.

Histological description and bone compactness analysis of fossil (Aldabrachelys sp.) and extant Aldabra giant tortoise (Aldabrachelys gigantea) shell bone fragments

open access: yesThe Anatomical Record, EarlyView.
Abstract Aldabra Atoll, north of Madagascar and part of the Seychelles Outer Islands, is home to the Aldabra giant tortoise, Aldabrachelys gigantea, the only survivor of several species of giant tortoises that were once widespread on islands across the Western Indian Ocean.
