We demonstrate a new approach to synthesize several unique nanostructures by tuning the selective reactivities on individual symmetry-breaking segmented selenium nanorods (SBS-SeNRs). The segment-selective reactions from thiolated silane endowed the formation of float-like SBS-SeNR@SiO2 with a silica coating on the t-Se segment. Several other unique nanostructures were further synthesized by applying other selective reactions, such as Se chemical removal and nanogold deposition. Such a segmented nanomaterial of SBS-SeNRs acts as a new chemical template for preparing various segmented nanocomposites. [ABSTRACT FROM AUTHOR]

A novel ternary hybrid of carbon nanotubes/graphitic carbon nitride nanosheets/gold nanoparticles was prepared and used as robust substrate electrodes for fabricating membrane-less glucose/O2 enzyme biofuel cells (EBFCs), and a remarkably improved power output was observed for the prepared EBFC.

A noncovalent macrocycle-within-noncovalent macrocycle assembly is formed from twelve molecules of (±)-1and twelve molecules of MeOH in the solid state. The H-bonded (MeOH)12cyclododecamer assumes a crown-shaped geometry that has not previously been predicted theoretically or found experimentally. [ABSTRACT FROM AUTHOR]
