A Multifunctional Mesoporous Janus Separator With Optimized Mass Transport Regulation Enabling 800‐Cycle Lithium‐Oxygen Batteries

Advanced Science, EarlyView.
To resolve the fundamental cycling decay of lithium‐oxygen batteries arising from lithium dendrite propagation, anode corrosion, and cathode passivation, we fabricate a mesoporous silica/polyurethane Janus separator integrating interfacial protection and mass transport modulation, which markedly enhances battery cycling stability and cycle life ...

Probing the Energy Landscape of α‐Synuclein Amyloid Fibril Formation by Systematic K‐to‐Q Mutagenesis

Advanced Science, EarlyView.
We use lysine‐to‐glutamine mutations to study the effect of electrostatics on the kinetics and thermodynamics of alpha‐synuclein amyloid fibril formation. We find that mutational effects map on their structural context within fibrils and identify residues that modulate the energy landscape of alpha‐synuclein self‐assembly. Our work outlines a scalable,
