Critical Review of Brazil Disk Techniques for Tensile Strength Characterization With an Emphasis on High Explosive Materials

Propellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT Mechanical properties are a critical performance metric for many high explosive (HE) materials and tensile strength properties are particularly important. Direct tensile measurements using dogbone shaped samples are the gold standard but they have the disadvantage that they are fairly large and require samples machined from billets.

Sex‐based differences in outcomes between male and female patients with bicuspid aortic stenosis following transcatheter aortic valve replacement: A meta‐analysis

Precision Medical Sciences, EarlyView.
Central illustration: Sex‐based differences in outcomes between male and female patients with bicuspid aortic stenosis following transcatheter aortic valve replacement. Abstract Bicuspid aortic valve (BAV) is a common congenital anomaly leading to early aortic stenosis.

Engaging the Complexities of Energy Transitions: Sociotechnical and Dualistic Insights From Crossdisciplinary Undergraduates

Science Education, EarlyView.
ABSTRACT Discourses of energy and energy transition have become increasingly prevalent in informal and formal learning spaces. Energy transitions differ across regions, contexts, and technologies. The contextual nature of energy is an opportunity for a sociotechnical approach to its study.

Single‐Particle Insights Into the Electronic Structure and Enhanced Stability of CsPbBr3/FAPbBr3 Core/Crown Nanoplatelets at the Nanometer Scale

Small, EarlyView.
Single‐particle‐level investigation using scanning tunneling spectroscopy reveals electronic structure and type‐I band alignment of individual CsPbBr3@FAPbBr3 core‐crown nanoplatelet. Crown passivation suppresses deep trap states by 47% and markedly improves electrical stability under repeated bias sweeps.

Generative AI—the Transgression of Technology

Systems Research and Behavioral Science, EarlyView.
ABSTRACT This article offers a systems‐theoretical analysis of generative artificial intelligence (GenAI) grounded in Niklas Luhmann's sociology of technology. It addresses a central conceptual problem: How GenAI can be understood within a theoretical framework that has traditionally defined technology as a means of stabilising action through causal ...

Strategic Spatial Segregation in Silicon Photoelectrodes: Decoupling Catalytic and Optical Functions for High‐Efficiency Solar Water Splitting

Small Structures, Volume 6, Issue 5, May 2025.
A novel spatial segregation strategy for silicon photoelectrodes is demonstrated, where catalyst wires surrounded by tapered microwires effectively decouple competing optical and catalytic requirements. This architectural innovation enables optimal light absorption and catalytic activity while maintaining efficient charge transport, achieving 96.5 ...
