Reactivity of Oxidized Porous Silicon with Calcium Ion in Aqueous Media: Stability, pH Behavior, and Host‐Guest Strategies

open access: yesSmall, EarlyView.
Oxidized porous silicon, composed of an elemental silicon porous skeleton coated with a silica shell, reacts with aqueous Ca2+ to generate a mixed silica–calcium silicate matrix that is remarkably efficient at trapping small molecules. With an emphasis on the engineering of controlled‐release drug delivery systems, this study identifies the factors ...

A Bilayer Rare‐Earth/High‐κ Oxide Memristor for Energy‐Efficient Neuromorphic Intelligence

open access: yesSmall, EarlyView.
Interface‐engineered Gd2O3/HfO2 bilayer memristors demonstrate controlled filament formation, ultralow switching energy (∼13.56 pJ), and fast operation (∼350 ns) with a high ON/OFF ratio (∼107). The devices exhibit stable analog synaptic behavior and enable pattern recognition on Fashion‐MNIST, underscoring their promise for energy‐efficient ...

MOF‐Derived Bi2WO6/MXene Ternary Heterojunction as a Highly Efficient Piezocatalyst for Ultrasound‐Driven Hydrogen Evolution and Oxygen Evolution Reaction

open access: yesSmall, EarlyView.
A Bi‐MOF‐derived Bi‐rich Bi2WO6/Bi3.84W0.16O6.24 ternary heterojunction with Ti2C MXene is developed as a highly efficient piezocatalyst. Ultrasound‐driven charge separation via a dual‐phase oxide and conductive MXene electron highway achieves an H2 evolution rate of 1450.1 µmol g−1h−1 through an unconventional •OH‐mediated pathway, with concurrent ...

Temporal Association Between COVID‐19 Vaccination and HBsAg Loss in Chronic Hepatitis B Infection: An Interrupted Time Series Analysis

open access: yesAlimentary Pharmacology &Therapeutics, EarlyView.
In 59,946 chronic hepatitis B patients followed over 23 years, COVID‐19 vaccination rollout was temporally associated with a 56% increase in HBsAg loss rates (peak 1.27 per 100 person‐years in 2022), followed by gradual waning. Negative control outcomes showed no similar pattern, supporting biological specificity. ABSTRACT Background and Aims Hepatitis
