ZrO2 Aerogel‐Supported Pd Nanoparticles for Photothermal CO2 Reduction

open access: yesAdvanced Science, EarlyView.
Nanoparticle‐based aerogels are promising catalysts for photothermal reactions due to optical transparency, high surface area, and low thermal conductivity. Here, we present deposition of Pd nanoparticles on ZrO2 aerogel granules by a wet‐impregnation approach.

Sustainable Carbon Fibers Enable Stable Long‐Term Lithium Metal Deposition for Prospective Zero‐Excess Lithium Metal Batteries

open access: yesAdvanced Energy Materials, EarlyView.
This work presents lightweight, lignin‐derived carbon fiber current collectors that enable controlled lithium deposition. Structural defects and intermediate‐sized pores stabilize pre‐nucleation quasi‐metallic lithium clusters, promoting uniform lithium plating and stripping.

THE EYE AND AVIATION [PDF]

open access: yesArchives of Neurology And Psychiatry, 1919
Samuel Johnson (1759), in his "Rasselas, Prince of Abyssinia," sets forth very graphically the principles of flying. He says: He that can swim needs not despair to fly; to swim is to fly in a grosser fluid, and to fly is to swim in a subtler. We have only to proportion our power of resistance to the different density of matter through which we are to ...

Current‐Driven Li2O Formation in Catalyst‐Free Solid‐State Li‐O2 Batteries Enabling Simultaneous High Energy and High Power

open access: yesAdvanced Energy Materials, EarlyView.
A catalyst‐free solid‐state Li‐O2 battery achieves current‐driven four‐electron Li2O formation, delivering simultaneous high‐energy and high‐power operation with 1032 Wh·kg−1 and 374 W·kg−1 in a single cell. ABSTRACT Li‐O2 batteries offer a compelling pathway toward next‐generation energy storage owing to their ultrahigh theoretical energy density ...
