Frame-by-frame observations of structure fluctuations in single mass-selected Au clusters using aberration-corrected electron microscopy
Changes in cluster structure have been observed via dynamic imaging in the scanning transmission electron microscope. This opens up the possibility of measuring the potential energy surface of metal clusters of different sizes.
Giant enhancement of the initial SERS activity for plasmonic nanostructures via pyroelectric PMN-PT
This paper presents a pyroelectric PMN-PT composite plasmonic Ag NP SERS substrate, whose initial SERS signal is further greatly enhanced under the action of a pyroelectric potential, with a dominant chemical mechanism.
Transition metal single atom-optimized g-C3N4 for the highly selective electrosynthesis of H2O2 under neutral electrolytes
TM SAs-optimized CNNS have been synthesized for the neutral electrosynthesis of H2O2. Compared with CNNS, the selectivity of Ni0.10 SA/CNNS for H2O2 increased from 61% to 98%. The H2O2 production rate of Ni0.10 SA/CNNS is 503 mmol gcat−1 h−1.
