Atomically Modulating Competing Exchange Interactions in Centrosymmetric Skyrmion Hosts GdRu2X2 (X = Si and Ge)

Advanced Electronic Materials, EarlyView.
Our work bridges the gap between skyrmion discovery and material design by demonstrating how atomic‐scale control of exchange interactions enables tunable skyrmion phase transitions in centrosymmetric magnetic metals. ABSTRACT Magnetic skyrmions are topologically protected spin states that hold promise for shaping the future of electronics.

Photolyzable Polymer Brushes: Subtractive 3D Structuring of Surfaces Using Water and Light

Angewandte Chemie, EarlyView.
Facile structuring of polymer brushes is achieved by flipping the process from controlled growth to controlled brush photolysis. Using surface‐initiated radical ring‐opening polymerization of cyclic monomers with photocleavable cyclobutane rings, photodegradable targets are embedded into the polymer chains. The enabled continuous subtractive patterning

RRAM Variability Harvesting for CIM‐Integrated TRNG

Advanced Electronic Materials, EarlyView.
This work demonstrates a compute‐in‐memory‐compatible true random number generator that harvests intrinsic cycle‐to‐cycle variability from a 1T1R RRAM array. Parallel entropy extraction enables high‐throughput bit generation without dedicated circuits. This approach achieves NIST‐compliant randomness and low per‐bit energy, offering a scalable hardware

Probing Steady‐State Carrier Properties and Charge Transport in Covalent Organic Framework by Frequency‐Domain Terahertz Spectroscopy

Angewandte Chemie, EarlyView.
This work reports a combined frequency‐domain and time‐domain terahertz (THz) spectroscopic approach to elucidate intrinsic carrier properties and transport mechanisms in framework materials over the extended 0.5–20 THz region. Subtle structural and chemical variations are shown to strongly influence THz charge‐transport behavior across the far ...

Finite element joint simulation model applied to fast mechanical switching of controlled resonance combination circuit breakers

High Voltage
Fast mechanical switches (FMSs) are critical components of DC circuit breakers (DCCBs), which require the switch action time to break to a sufficient distance within 3 ms in the DC line breaking scenario, while ensuring a long service life.

A Deep‐Red‐Absorbing Osmium(II) Complex as a Photosensitizer for Photodynamic Therapy Inducing Immunogenic Cell Death

Angewandte Chemie, EarlyView.
A deep‐red‐excited osmium(II) photosensitizer (Os2) induces immunogenic cell death (ICD) under 740 nm irradiation and triggers robust anti‐tumor immune responses both in vitro and in vivo. ABSTRACT Immunogenic cell death (ICD), which converts tumor cells into their own vaccine, plays a pivotal role in the development of novel anticancer therapies. Here,

Inversion of the Impedance Response Towards Physical Parameter Extraction Using Interpretable Machine Learning

Advanced Energy Materials, EarlyView.
ABSTRACT Interpreting the impedance response of perovskite solar cells (PSCs) is challenging due to the complex coupling of ionic and electronic motion. While drift‐diffusion (DD) modelling is a reliable method, its mathematical complexity makes directly extracting physical parameters from experimental data infeasible.
