Finite groups whose coprime graphs are AT-free

open access: yesElectronic Research Archive
Assume that $ G $ is a finite group. The coprime graph of $ G $, denoted by $ \Gamma(G) $, is an undirected graph whose vertex set is $ G $ and two distinct vertices $ x $ and $ y $ of $ \Gamma(G) $ are adjacent if and only if $ (o(x), o(y)) = 1 $, where

Buckling‐Resistant and Trace‐Stacked (BRATS) Design Enables Aid‐Free Implantation of Flexible Multielectrode Array with Minimized Inflammatory Tissue Response

open access: yesAdvanced Functional Materials, EarlyView.
Buckling‐resistant and trace‐stacked (BRATS) intracortical microelectrode arrays (MEAs) eliminate the need for insertion aid and complex surgical setup, resulting in minimal inflammatory tissue response, compared to conventional flexible MEAs inserted with aid. Trace stacking effectively doubled the channel count without increasing the MEA shank width,

Microfluidic Synthesis of Channel‐Rich Pd‐Cu Alloy Nanodendrites for Efficient Electrocatalytic CO2 Reduction to Formate

open access: yesAdvanced Functional Materials, EarlyView.
A microfluidic system enables the rapid, room‐temperature fabrication of channel‐rich Pd‐Cu alloy nanodendrites with tunable composition, uniform morphology, and finely branched internal structures. The resulting catalysts exhibit over 90% formate selectivity across a broad potential window, along with excellent CO tolerance and enhanced long‐term ...

Microscale Tin–Bismuth Alloy Prepared via Cooling Rate Control as Anode Material for High‐Performance Lithium‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
To investigate the mechanisms about the enhanced buffering effect and morphological retention in fully lithiated Sn–Bi alloys, this study introduces a new bulk bimetallic Sn–Bi alloy with fine grains of uniformly distributed Sn and Bi alloys (≈50 nm) via cooling rate control. This design effectively relieves internal energy buildup and suppresses crack

Engineering Highly Cellularized Living Materials via Mechanical Agitation

open access: yesAdvanced Functional Materials, EarlyView.
A mechanical agitation strategy is developed to engineer highly cellularized living materials, achieving cell densities of up to 1 billion cells per milliliter. By precisely tuning properties such as stiffness and toughness in blood clots, the approach is validated in both in vitro and in vivo studies.
