A Stopped‐Flow Instrument for Millisecond Timescale Reaction Monitoring on a Standard NMR Spectrometer

open access: yesMagnetic Resonance in Chemistry, Volume 64, Issue 8, Page 711-728, August 2026.
A new stopped‐flow instrument allows kinetic measurements of reactions 10 milliseconds after initiating them by mixing in a flow cell inserted into a standard NMR probe and spectrometer. High‐speed video, pressure and NMR line‐shape data are used to characterise mixing and stopping, and a protodeboronation reaction with a 5‐millisecond half‐life used ...

The Evolution of Semiconductor Devices: From Transistors to Quantum and Neuromorphic Computing

open access: yesphysica status solidi (RRL) – Rapid Research Letters, Volume 20, Issue 8, August 2026.
This review presents the evolution of semiconductor devices from BJTs to fin field‐effect transistors (FinFETs), nanowire, and carbon nanotube transistors. It highlights emerging materials, including SiC and GaN, and examines neuromorphic and quantum computing, industry applications, performance benchmarks, challenges, and future directions.

Decoding Superconductivity in La3Ni2O7−δ Thin Films via Ozone‐Driven Structure and Oxidation Tuning

open access: yesSmall Structures, Volume 7, Issue 8, August 2026.
We demonstrate that superconductivity in La3Ni2O7‐δ thin films correlate with the LNO‐2222 polytype, which must extend coherently across the layer. Conversely, the LNO‐1313 phase disrupts superconductivity, as confirmed by recent studies. Our work highlights the need to stabilize the 2222 phase through optimized growth to achieve robust and ...

Basins of Attraction and Escape in Pendulum‐Type Potentials with Quadratic Air Drag

open access: yesZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 106, Issue 8, August 2026.
ABSTRACT Quadratic air drag is a common dissipative mechanism at moderate to high velocities, yet in nonlinear one‐degree‐of‐freedom systems, it typically blocks closed‐form solutions and energy‐based phase‐plane partitions. We study the autonomous class ẍ+α(x)|ẋ|ẋ+β(x)sgn(ẋ)+V′(x)=0,$$\begin{equation*} \ddot{x}+\alpha (x)\,|\dot{x}|\,\dot{x}+\beta

Automated Mineral Identification and Rock‐Type Classification of Lunar Mare Basalts Using SEM Images

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract We present an automated system for identifying minerals and classifying rock types in Apollo lunar mare basalts using scanning electron microscopy (SEM) imagery. Mineral segmentation is based on a U‐Net architecture, supplemented by two scale‐aware models designed to incorporate pixel size information.
