Reconfigurable Giant Nonreciprocity at Near‐Normal Incidence via Phase‐Change Magneto‐Optical Metagratings

open access: yesLaser &Photonics Reviews, EarlyView.
A phase‐change magneto‐optical metagrating combines GST switching with InAs guided‐mode resonances to achieve strong nonreciprocal absorption contrast near normal incidence. A static magnetic bias creates direction‐dependent resonant splitting, while GST crystallization quenches and latches the response.

Multi‐Responsive PAA/PNIPAM Semi‐IPN Hydrogel Properties Controlled by PAA Topology

open access: yesMacromolecular Rapid Communications, EarlyView.
Polymer topology governs hydrogel behavior in semi‐interpenetrating networks. Cyclic poly(acrylic acid) enables controlled pH‐responsive swelling, improved stability, and enhanced deformability compared to linear analogues, while linear systems show higher strength during thermal de‐swelling.

First 20 Years of Orbitrap Mass Spectrometry as the Mainstream Analytical Technique

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT This review traces the first 20 years of Orbitrap mass spectrometry as a mainstream high‑resolution and accurate‑mass (HR/AM) technology. It outlines the historical development of the Orbitrap analyzer, the evolution of major instrument families, and the key technological innovations that enabled its widespread adoption. Particular emphasis is

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

open access: yesMagnetic Resonance in Chemistry, EarlyView.
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 ...

A Modified Balanced Steady State Free Precession Sequence for Overhauser Magnetic Resonance Imaging

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Low‐ and ultralow‐field magnetic resonance imaging (ULF MRI) have inherently low signal‐to‐noise ratio (SNR) by design. Overhauser dynamic nuclear polarization (ODNP) stands out as an effective solution for continuous signal enhancement.
