Defect-induced displacement of topological surface state in quantum magnet MnBi2_2Te4_4

This study demonstrates that high concentrations of intrinsic antisite defects in the topological magnet MnBi2_2Te4_4 displace the topological surface states deep into the crystal bulk, thereby suppressing the surface gap and resolving the long-standing discrepancy between experimental observations and theoretical predictions.

Quantifying Local Point-Group-Symmetry Order in Complex Particle Systems

This paper introduces Point Group Order Parameters (PGOPs) as a new set of metrics to directly quantify local point-group symmetry in complex particle systems, demonstrating their superior utility in detecting crystalline order compared to traditional bond-orientational parameters and providing their implementation in the open-source SPATULA software package.

High Uniformity GaN Micro-pyramids and Platelets by Selective Area Growth

This study addresses the issue of morphological non-uniformity in GaN micro-pyramids and platelets grown via MOCVD by identifying the limitations of one-step growth and demonstrating that a controlled multi-step strategy combining sequential growth and thermal treatment significantly enhances structural regularity for advanced optoelectronic applications.

Multiscale Analysis of Plasma-Modified Silk Fibroin and Chitosan Films

This study demonstrates that biological interactions with plasma-modified silk fibroin and chitosan surfaces are scale-dependent, revealing that bacteria respond to fine-scale topographic features while macrophages correlate with larger-scale features, thereby suggesting that tailoring surface topography to specific biological length scales is a promising strategy for developing antibacterial wound-healing materials.

Stress Asymmetry in Hard Magnetic Soft Materials

This paper demonstrates that while continuum magnetomechanical formulations for hard magnetic soft materials yield different Cauchy stress symmetries depending on whether the magnetization is described in the referential or current configuration, both formulations converge to symmetric stresses with identical equilibrium behavior when the magnetization field is at its energy-minimizing state.
