A simultaneous optical and electrochemical recording method was proposed to study dynamic electrochemical reactions during single nanoparticle collisions; this method enables an effective bottom-up strategy of elucidating the structure (optical signal)-activity (electrochemical signal) relationship at a single nanoparticle level.

Carbon nanoflakes with an unparalleled combination of a large surface area,mesoporosity, and oxygen and nitrogen content are created through the single-step carbonization activation of (2-benzimidazolyl) acetonitrile. When used in supercapacitor electrodes, these carbons exhibit an excellent specific capacitance and a high rate capability in both basic and neutral aqueous electrolytes.

A porous Sb/Sb2O3 nanocomposite has been synthesized by the mild oxidation of highly aggregated Sb nanocrystals. A low charge voltage inhibits the formation of Sb2O3 and reduces the volume change upon cycling, improving the capacity at 10 A·g-1 to 412 mAh·g-1, which is ~71.6% of the capacity at 0.066 A·g-1.

Scanning electron microscopy (SEM) images of single-walled carbon nanotubes (SWCNTs) on substrates are produced by the combination of signals from the topography, material, and surface charge. Modulating these factors yields m- and s-SWCNTs with various appearances.

Co-vacancy-rich Co1-xS nanosheets were anchored on reduced graphene oxide (rGO) via a successive two-step hydrothermal reaction. The ultrathin nanosheets increased the quantity of cobalt vacancies (V'Co) and exposed them on the surface. Experimental results and density functional theory calculations indicated that the V'Co derived from the non-stoichiometric and sheet-like structure enhanced the oxygen evolution reaction activity of the Co1-xS/rGO hybrid.

A deposited Co2 cluster dissociates on ultrathin NaCl films grown on an Au (111) substrate, whereas a larger Co13 cluster does not fragment and remains stable atop the NaCl film.
