·6H2O as raw material. The mechanism for the formation of amorphous Co-P nanoparticles on BP nanosheets is proposed as follow (Fig.1a). Layered red phosphorus is formed initially via the conversion of white phosphorus at room temperature with the assistance of ethylenediamine, which is revealed...

Because most of the factors measured have endogenous binding partners, probing the structural accessibility of the nuclear interior independent of their specific interactions was not feasible. Although in other reports GFP§§ was used as an inert tracer protein to probe the nuclear interior, no ...
