Proton Acceleration with Relativistic Electromagnetic Shock
Advanced Science, EarlyView.New Ion Acceleration Mechanism! A novel cosmic‐ray proton acceleration mechanism is proposed, where relativistic electromagnetic shocks accelerate protons transversely. Hamiltonian analysis yields a scaling law linking the proton energy to the minimum longitudinal thickness of the shock.

Advanced Energy Materials, EarlyView.Herein, by employing a reference electrode, the durability of anion exchange membrane water electrolyzer (AEMWE) under intermittent condition is demonstrated to be governed by the stability of the cathode catalyst. By encapsulating NiMo catalyst with carbon shells, the oxidation‐induced irreversible transformation to inactive hydroxide is prevented ...

Metal Sulfides as Potential Materials for Next Generation Lithium Ion Batteries: A Review
Advanced Energy and Sustainability Research, EarlyView.The flame spray pyrolysis (FSP) method demonstrates its superiority in fabricating metal sulfide‐based electrodes without inactive materials like organic binders or solvents. The particles are directly deposited and compressed onto the electrode surface, integrating into continuous production.
