Woven Eutectic Lamellar Structures Lead to Ultrahigh Strength and Energy Absorption Capacity in Additively Manufactured Lattice Structures

Small Structures, Volume 6, Issue 5, May 2025.
Herein, AlCoCrFeNi2.1 is selected to produce lattice structures by selective laser melting. The as‐printed lattice structures consist of numerous colonies of nanosized eutectic lamellar structures which are bent and interwind with each other to form a woven microstructure. The unique microstructure leads to unprecedented effective metal strength, yield

High‐Entropy Interfacial Optimized 3D Nano‐Collector Enables Dendrite‐Free and Ultra‐Stable Lithium Metal Batteries

SusMat, EarlyView.
By integrating a MnNiVCrFe HEA interphase with a 3D NF scaffold, this 3D current collector homogenizes the interfacial electric field and Li+ distribution. This synergistic interphase–structure modification strategy enables uniform lithium nucleation and deposition, thereby suppressing dendrite formation and boosting interfacial stability. Consequently,

Lobbying and Political Risk Disclosure: Do Socially Responsible Firms Voluntarily Disclose More?

British Journal of Management, EarlyView.
Abstract Drawing on theories of strategic communication, legitimacy, impression management and moral capital, this study investigates whether firms use political risk disclosure to offset negative perceptions associated with corporate lobbying. Using a sample of 10,120 observations from 1362 US firms between 2002 and 2018, we find that firms with ...
