Numerical analysis of ballistic impact performance of two ceramic-based armor structures
Composites Part C: Open Access, 2020 This paper investigates ballistic performance of two different ceramic-based armor designs using finite element analysis. The first design is a bi-layer armor consists of a ceramic front layer and a Kevlar-29 composite backing layer.

Cation Diffusion‐Mediated Displaced Reaction‐Transformation in Green Steelmaking
Advanced Science, EarlyView.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 ...

Advanced Electronic Materials, EarlyView.Monolayer PtTe2 enables dopant‐free Schottky FETs through its thickness‐dependent electronic transition. Quantum transport simulations show that crystallographic orientation strongly influences device performance, with Γ–M transport delivering higher drive current, lower leakage, and improved switching behavior.

Controllable Ge Hut Wires With Mobilities Exceeding 20 000 cm2 V−1 s−1
Advanced Electronic Materials, EarlyView.The controlled growth of germanium hut wires on patterned SiGe/Si(001) substrates is reported. These self‐assembled nanowires achieve a record hole mobility of 22 900 cm2 V−1 s−1 at 4.2 K. Remarkably, conductance quantization is observed at a channel length of 1.9 µm, highlighting their exceptionally low disorder and paving the way for scalable, high ...
