Advanced Functional Materials, EarlyView.From a database of 170 pentagonal 2D materials, 4 candidates exhibiting altermagnetic ordering are screened. Furthermore, the spin‐splitting and unconventional boundary states in the pentagonal 2D altermagnetic monolayer MnS2 are investigated. A MnS2‐based altermagnetic tunneling junction is designed and, through ab initio quantum transport simulations,

Advanced Functional Materials, EarlyView.This work utilizes poly(heptazine imides) as a model system to demonstrate how fine‐tuning the crystal structure influences the photocatalytic properties of layered carbon nitrides in the hydrogen evolution reaction. In particular, the nature of rotational defects and the hydration shell of cations are key contributors to enhanced hydrogen evolution ...

Cell Surface Thiol Engineering Mechanoregulates Myogenic Differentiation via the FAK–PI3K–AKT Axis
Advanced Healthcare Materials, EarlyView.Schematic diagram illustrating how cell surface modification of skeletal muscle progenitor cells through TCEP treatment reveals enhanced cell adhesion, intracellular tension, and myogenesis at 19.66 kPa stiffness, leading to optimal cell fusion. In contrast, no significant changes are observed in the softer (10.61 kPa) or stiffer (49.4 kPa) matrices ...

Factor analysis of correlation matrices when the number of random variables exceeds the sample size
Statistical Theory and Related Fields, 2017 Factor analysis which studies correlation matrices is an effective means of data reduction whose inference on the correlation matrix typically requires the number of random variables, p, to be relatively small and the sample size, n, to be approaching ...
