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.

Programmable Flocks: Hierarchical Swarm Control via Dynamic Parameter Injection

Advanced Intelligent Systems, EarlyView.
We present a method for the control of robot swarms which allows the shaping and the translation of patterns of simple robots (“smart particles”), using two types of devices. These two types represent a hierarchy: a larger group of simple, oblivious robots (which we call the workers) that is governed by simple local attraction forces and a smaller ...

Omnidirectional Shape Proprioception for Untethered Shape Memory Alloy‐Driven Soft Robotic Arms

Advanced Intelligent Systems, EarlyView.
A lightweight, modular soft robotic arm employs SMA actuation and a multi‐Hall‐magnet sensing system to achieve accurate omnidirectional shape proprioception. Each 35 g segment enables scalable assembly, while robust proprioception supports versatile navigation and manipulation in complex, unstructured environments.

Exploration of Physical Properties of Sodium‐Based Perovskite Hydrides ANaH3 (A = Hf, Nb, Pd, Ru) for Hydrogen Storage Applications: First Principles Study

Advanced Physics Research, EarlyView.
First‐principles calculations reveal that ANaH3 (where A = Hf, Nb, Pd, Ru) perovskite hydrides combine structural stability, favorable electronic properties, and low hydrogen desorption temperatures (280–369 K). Strong metal–hydrogen interactions and reversible hydrogen storage characteristics identify these materials as promising candidates for ...
