Engineering Flow‐Through Hollow Fiber Gas‐Diffusion Electrodes for Unlocking High‐Rate Gas‐Phase Electrochemical Conversion

open access: yesAdvanced Materials, EarlyView.
Advancing gas‐phase electrolysis toward industrial‐scale applications requires not only the development of advanced electrocatalysts but also the design of the electrodes to optimize gas‐electrode‐electrolyte interfaces and facilitate efficient mass transport, thereby reinforcing gas win the electrons to promote reaction kinetics and suppress side ...

Round barrows and dykes as landscape metaphors [PDF]

open access: yes, 2004
This article outlines the results of phenomenological research on the significance of landscape features, in particular ridges and coombe (dry valley) systems, in relation to the locations of Bronze Age round barrows and late Bronze Age/early Iron Age ...

Designing Maximal Strength in Nanolamellar Eutectic High‐Entropy Alloys

open access: yesAdvanced Materials, EarlyView.
This study uses molecular dynamics simulations to guide the design of EHEAs with superior mechanical performance. The simulations reveal a peak tensile strength at a critical interphase boundary spacing. Below this spacing, the governing mechanism shifts from the Hall–Petch strengthening to dislocation multiplication–mediated softening. Guided by these

Ultrahigh Conductive MXene Films for Broadband Electromagnetic Interference Shielding

open access: yesAdvanced Materials, EarlyView.
A new series of nitrogen‐substituted MXene films, spanning the full composition range, achieves record‐high conductivity (35 000 S cm⁻¹) and outstanding electromagnetic interference (EMI) shielding across X, Ka, and W bands, even in ultrathin layers.
