Turning Microstructure in Block Copolymer Membranes: A Facile Strategy to Improve CO2 Separation Performance

Advanced Science, EarlyView.
A simple and effective non‐solvent‐induced microstructure rearrangement (MSR) technique is proposed to enhance the gas separation performance of Pebax 2533 membranes. By immersing Pebax 2533 membranes in amino acid salt solutions to induce MSR, the CO2 permeability of the Pebax 2533‐GlyK 10 wt.% membrane reached 1180 Barrer.

Sinter‐ and Water‐Resistant Pt Enabled by High Entropy of Porous Oxide Nanofibers

Advanced Science, EarlyView.
The high‐entropy effect thermodynamically favors a unique distribution of multiple constituent elements within the crystalline lattice with low Gibbs free energy. This special configuration endows the material with exceptional stability, depressing the growth of Pt species at elevated temperatures.

Advanced Temperature Design for Dynamic Performance Enhancement of PEMFCs Under High Current Density (HCD)

Advanced Science, EarlyView.
This study presents an innovative temperature difference (TD) design with an in‐plane gradient to optimize cooling channels in proton exchange membrane fuel cells (PEMFCs) under high current density (HCD) loading. The positive temperature difference (PTD) design improves dynamic response by enhancing hydration upstream and mitigating flooding ...
