recommendations! Published in 2020 at "Advanced Functional Materials"

DOI: 10.1002/adfm.202005956

Abstract: Silicon has attracted considerable interest as a high‐capacity anode material for next‐generation lithium‐ion batteries. However, Si‐based anodes suffer extreme volume change (≈380%) upon lithiation and delithiation, which results in rapid capacity fading due to mechanical… read more here.

DOI: 10.1002/aoc.3978

Abstract: We report a simple process for the synthesis of Fe3O4@SiO2/APTMS (APTMS = 3-aminopropyltrimethoxysilane) core–shell nanocatalyst support. The new nanocatalyst was prepared by stabilization of Pd(cdha)2 (cdha = bis(2-chloro-3,4-dihydroxyacetophenone)) on the surface of the Fe3O4@SiO2/APTMS support. The structure and composition… read more here.
