Unraveling diverse survival strategies of microorganisms to vanadium stress in aquatic environments.
TL;DR: In this paper , the authors investigated the potential survival strategies of microbial communities and associated pathways in aquatic environments based on geochemistry and molecular biology and revealed three survival strategies including denitrification pathway, electron transfer, and metal resistance in innate microbes under the vanadium stress.
Journal ArticleDOI
Dissection of the antibacterial mechanism of zinc oxide nanoparticles with manipulable nanoscale morphologies.
TL;DR: In this article , a controllable thermal decomposition of ZnO nanoparticles of different morphologies was facilely prepared, and the surface PEGylation was conducted to obtain the nanoparticles with low biotoxicity, in which the ultra-small ones (~5 nm) showed the best performance.
