Non-graphitized carbon/Cu2O/Cu0 nanohybrids with improved stability and enhanced photocatalytic H2 production
Synthesis of nGC/Cu2O/Cu0 heterojunctions by anoxic-flame spray pyrolysis The anoxic-FSP synthesis of Cu NPs was carried out within an enclosed-flame FSP reactor, with a dispersion feed consisting of {oxygen (O2)–methane (CH4)} mixture that allows creation of a strongly reducing atmosphere in the flame (Fig. 1b i–ii)39. N2 sheath gas was used to further maintain the anoxic…

Visualizing single-molecule conformational transition and binding dynamics of intrinsically disordered proteins
Device fabrication and real-time electrical monitoring The SiNW-FET-based single-molecule device was fabricated through point modification and a confinement reaction on the side wall of a SiNW48,53,54. Briefly, after the fabrication of the SiNW-FET array, a gap-opening process was performed using electron beam lithography to create a nanogap on the side wall of the SiNW and…
