Anomalous Valley Zeeman Splitting Induced by In‐plane Magnetic Fields in a Mo0.7W0.3Se2 Monolayer

Advanced Quantum Technologies, Volume 9, Issue 4, April 2026.
In‐plane magnetic fields produce an anomalous valley Zeeman splitting in a Mo0.7W0.3Se2${\rm Mo}_{0.7}{\rm W}_{0.3}{\rm Se}_2$ monolayer – a response forbidden in binary transition‐metal dichalcogenides. Photoluminescence g‐factors of ‐6 to ‐7 exceed resonant scattering values by a factor of four, revealing a many‐body origin.

Conundrums of Localized Surface Plasmon Resonance Biosensors

Small, Volume 22, Issue 19, 1 April 2026.
Localized surface plasmon resonance (LSPR) biosensing faces fundamental conundrums arising from finite field decay lengths, environmental cross‐sensitivities, and batch variability. Competing surface, bulk, and electrostatic effects can induce red or blue spectral shifts, complicating quantification, reproducibility, and interpretation in complex or ...

Cationic Lattice Coupling Enables Efficient FAPbI3 Perovskite Solar Cells

Small Structures, Volume 7, Issue 4, April 2026.
TPPI with a rigid, asymmetric phosphonium framework orient stably at the grain boundaries and interfaces of PSCs. It polarizes FA+, reinforces hydrogen bonds, restricts FA+ rotation to stabilize the α‐phase, and enhances cation–lattice coupling to form large polarons for defect screening, thereby boosting the power conversion efficiency (PCE) and ...

Weibull‐Neural Network Framework for Wind Turbine Lifetime Monitoring and Disturbance Identification

Wind Energy, Volume 29, Issue 4, April 2026.
ABSTRACT Wind turbines are vital for sustainable energy, yet their reliability under diverse operational and environmental conditions remains a challenge, often leading to costly failures. This study presents a novel Weibull‐Neural Network Framework to enhance wind turbine lifetime monitoring by estimating reliability (R(t)) and mean residual life (MRL)

Detection of an Antagonist Bound to the Neurokinin a Receptor in Styrene–Maleic Acid Lipid Particles by 19F Ultrafast Magic‐Angle Spinning Nuclear Magnetic Resonance Spectroscopy

ChemBioChem, Volume 27, Issue 6, 27 March 2026.
The detection of a fluorinated antagonist bound to the neurokinin A receptor by 19F ultrafast MAS NMR is demonstrated. Therefore, the receptor is purified by detergent‐free extraction by styrene maleic acid copolymer encapsulation and subsequently characterised.

Collecting Large Datasets of Unambiguous Structural Restraints for Protein Structure Determination by 4D Proton‐Detected Solid‐State NMR

ChemPhysChem, Volume 27, Issue 6, 27 March 2026.
Proton detection, nonuniform sampling in 4D spectra, multiplexing, deuteration, and stereospecific labeling of methyl groups allowed for the collection of several hundred unambiguous long‐range distance restraints by solid‐state NMR for the rigid core of the bactofilin BacA.

An Inkjet‐Printed Platinum‐Based Temperature Sensing Element on Polyimide Substrates

Advanced Engineering Materials, Volume 28, Issue 6, 18 March 2026.
An inkjet‐printed, meander‐structured, nanoparticle platinum‐based resistive temperature sensors on polyimide substrates are demonstrated as proof‐of‐concept. Optimized sintering at 250°C enables stable conductive structures. The Pt100‐ and Pt1000‐type sensors exhibit linear resistance–temperature characteristics with stable TCR in the 20°C–80°C range,

Merging van der Waals Materials and Optical Metasurfaces for Cavity Quantum Electrodynamics

Nanophotonics, Volume 15, Issue 5, 16 March 2026.
Flat optical metasurfaces supporting quasi‐bound states in the continuum (qBIC) enable cavity‐like, high‐Q resonances in ultrathin nanostructures. This perspective explores the emergence of cavity quantum electrodynamics in qBIC metasurfaces, specifically those made from ultrathin van der Waals nanostructures, where cavities and emitters are seamlessly
