This is a diagram of an adsorption device with 2 adsorption columns, the input air is to the far left and the product is on the top right corner. Can someone tell me its working principle?
I read a paper, that said they had dissolved PS by putting 7.5wt% PS in 46.25wt% HFIP and 46.25wt% DMF, stirring overnight. Is that true? How can I dissolve PS for electrospinning?
