recommendations! Published in 2024 at "Advanced Materials"

DOI: 10.1002/adma.202313096

Abstract: Despite the increasing effort in advancing oxygen electrocatalysts for zinc‐air batteries (ZABs), the performance development gradually reaches a plateau via only ameliorating the electrocatalyst materials. Herein, a new class of external field‐responsive electrocatalyst comprising Ni0.5Mn0.5Fe2O4… read more here.

DOI: 10.1017/s0022377820000045

Abstract: When two collisionless plasma shells collide, they interpenetrate and the overlapping region may turn Weibel unstable for some values of the collision parameters. This instability grows magnetic filaments which, at saturation, have to block the… read more here.

DOI: 10.1021/acs.jctc.4c01342

Abstract: Colloidal particles with anisotropic geometries and interactions display rich phase behavior and hence have the potential to serve as the basis of functional materials, which can tunably and reversibly self-assemble into different configurations. External fields… read more here.

DOI: 10.1038/srep39996

Abstract: We investigate the electrostatic charging of an agitated bed of identical grains using simulations, mathematical modeling, and experiments. We simulate charging with a discrete-element model including electrical multipoles and find that infinitesimally small initial charges… read more here.
