However,in time,no reaction of any of the lipid moieties could be observed,indicating the absence of the same,using various histochemical techniques.The results are discussed in light of the mechanistic understanding of detergent action.1989 Academic Press,Inc.展开更多

Herein, we described a facile route for synthesizing graphene-Cu and graphene-Cu2 O nanocomposites using graphene oxide-Cu O as a precursor. Remarkably, the different nanocomposites could be formed just by varying the reaction temperature and time. This work provides a feasible route for the preparation of graphene-based nanocomposites with various constituents.展开更多
