Z‐Scheme Water Splitting Systems Based on Solid‐State Electron Conductors
Advanced Functional Materials, EarlyView.This review examines the latest advances in Z‐scheme overall water splitting (OWS) systems for solar hydrogen production. These systems consist of suspended or immobilized hydrogen evolution photocatalysts (HEPs) and oxygen evolution photocatalysts (OEPs).

Numerical calculation of the parameters of the efflux from a helium dewar used for cooling of heat shields in a satellite [PDF]
The parameters of the efflux from a helium dewar in space were numerically calculated. The flow was modeled as a one dimensional compressible ideal gas with variable properties.

Volume-reflecting dielectric heat shield [PDF]
, 1974 White, volume-reflecting dielectric material absorbs essentially none of the incident radiant energy, and continues to reflect even though in severe environment its surface is melted and is being vaporized.

Advanced Functional Materials, EarlyView.Wood‐based broadband blackbody is achieved by reconfiguration of wood with lignin nanoparticles prior carbonization. Neglectable reflectivity from the visible to infrared wavelengths is obtained by combining thin nanostructures originated from the wood cell walls with long‐range microcavities in the wood lumina.

Space nuclear reactor shields for manned and unmanned applications [PDF]
Missions which use nuclear reactor power systems require radiation shielding of payload and/or crew areas to predetermined dose rates. Since shielding can become a significant fraction of the total mass of the system, it is of interest to show the effect
