The videos on my channel will be mainly aimed at the Scottish National 5, Higher and Advanced Higher qualifications, however they will be general enough to be used by anyone interested in revising for chemistry exams. Youtube Channel youtube.com/channel/UCU32.. Subscribe YouTube Subscribers ...
Those numbers for chemists don’t look all that big to me (and others have said so on Twitter too). And if the sample identified in this paper is representative of Twitter as a whole, it means that there are something like 10-20 times more physicists on Twitter than there are chemists....

The ability of metal nanostructures to precisely control size, shape, charge, and surface modifications makes higher-density metal nanostructures more amenable to cell replacement than similarly sized nonmetal nanopreparations, providing benefits for tumor vaccination strategies. The unique optical properties ...
and 128.6 LMH bar−1for the PES/PSBAE membrane, respectively. These values were still much higher (2 to 3 fold) than for many PDA modified/coated LNF membranes reported for similar applications in the filtration of synthetic textile wastewater (Zhu et al., 2016;Wang et al., 2019;Li et...
