Cation Diffusion‐Mediated Displaced Reaction‐Transformation in Green Steelmaking

Advanced Science, Volume 13, Issue 56, 9 October 2026.
The removal of O lattice atoms by environmental H2 at the surface of Fe3O4 results in Fe enrichment, driving the inward diffusion of Fe cations into the bulk. Through hopping between unoccupied and initially occupied sites, cation diffusion triggers a spatially displaced reaction‐transformation and drives subsequent dynamic phase transformations and ...

Simulation and Analysis of Stiffened Auxetic Honeycombs Having Enhanced High Impact Velocity Response

Applied Research, Volume 5, Issue 5, October 2026.
The ballistic resistance of auxetic re‐entrant honeycomb structures can be significantly improved through geometric tailoring and structural reinforcement. Vertical and horizontal stiffening ribs enhanced the ballistic performance, increasing the energy absorption efficiency by 119.45% and the projectile velocity reduction by 281.36%, ultimately ...

A Hybrid Physics‐Informed Computational Framework for Adaptive Microrobotic Navigation and Causal Structure Discovery in Simulated Non‐Newtonian Environments

Applied Research, Volume 5, Issue 5, October 2026.
This study presents a hybrid AI framework that enables autonomous magnetic microrobots to navigate complex, non‐Newtonian tumor microenvironments. By integrating physics‐informed recurrent reinforcement learning with active persistent excitation, the system successfully infers hidden fluid rheology for precise targeted navigation and structural causal ...
