Spectrally Tunable 2D Material‐Based Infrared Photodetectors for Intelligent Optoelectronics

Advanced Functional Materials, Volume 36, Issue 27, 2 April 2026.
Intelligent optoelectronics through spectral engineering of 2D material‐based infrared photodetectors. Abstract The evolution of intelligent optoelectronic systems is driven by artificial intelligence (AI). However, their practical realization hinges on the ability to dynamically capture and process optical signals across a broad infrared (IR) spectrum.

Triggered Ferroelectricity in HfO2 From Hybrid Phonons and Higher‐Order Dynamical Charges

Advanced Materials, Volume 38, Issue 19, 1 April 2026.
We combine first‐principles calculations, LGD theory and group theory to demonstrate the mechanism of hybrid‐triggered ferroelectricity in HfO2${\rm HfO}_2$, enabled by trilinear and quadlinear couplings between stable polar and nonpolar modes. HfO2${\rm HfO}_2$ hosts unconventional interplay between structure modes where substantial contribution to ...

Real‐time energy measurement of clinical carbon ion beams using a cross‐correlation time‐of‐flight method with parallel‐plate chambers

Medical Physics, Volume 53, Issue 4, April 2026.
Abstract Background In carbon‐ion radiotherapy (CIRT), the beam energy determines both the particle range and the overall dosimetric quality. Range‐verification QA devices such as Zebra and Giraffe, which are based on multilayer ionization chambers (MLICs), can verify the range but only under dedicated QA conditions, leaving any energy deviations ...

Toxic mechanisms of amyloid oligomers and therapeutic strategies

Protein Science, Volume 35, Issue 4, April 2026.
Abstract Amyloid oligomers are increasingly recognized as the major toxic contributors across protein‐misfolding disorders. In this review, we cover mechanistic evidence showing how these transient and structurally heterogeneous oligomers disrupt cellular homeostasis by: (i) permeabilizing lipid membranes and forming ion‐conducting pores; (ii ...
