Abstract AlB2 and SiB4 are used as active particles to design model SiO2‐20 vol.% active particles composites for high‐temperature applications. The oxidation of AlB2 and SiB4 particles in air at T = 1000°C–1050°C rapidly leads to the formation of an important quantity of liquid that can heal cracks.

Helicosphaera carteri (Prymnesiophyceae) under high carbon dioxide: An experimental study
Abstract The coccolithophore Helicosphaera carteri is an understudied, yet ecologically and biogeochemically important, marine calcifier. Hence, its response to ocean acidification has implications for ecosystem function and the marine carbon cycle. Here we employed dilute batch cultures featuring a coupled C‐system manipulation (295, 444, and 600 μatm

A Perspective on Pathways Toward Commercial Sodium‐Ion Batteries
Comprehensive analysis of the existing and prospective sodium‐ion battery (SIB) systems unveils that a wider application of SIBs should primarily focus on i) regulating the composition, morphology, surface chemistry, safety performance, and production feasibility of mainstream cathodes, ii) enhancing the high‐voltage stability, film formation ability ...
