A series of phase-separated porous, raspberry-, flower-like, core–shell, anomalous nanoparticles and nanocapsules are prepared by a facile one-step 1,1-diphenylethene controlled soap-free emulsion copolymerization, where the unpolymerized monomer resulted from low conversion due to 1,1-diphenylethene functions as an in situ porogen to produce porous particles and nanocapsules. The drug loading and release behaviors of the porous particles and nanocapsules are investigated.

A sandwich-structured nanocomposite of N-doped graphene and nearly monodisperse Fe3O4 nanoparticles were developed as Li-ion battery anode. With N-doped graphene as the framework that controls Fe3O4 nucleation, it exhibits good electron conductivity and Li-ion accessibility and can accommodate a large volume change, thereby delivering a capacity of ~1,227 mA·h·g–1 and 96.8% retention over 1,000 cycles.

A three-dimensional plasmonic double-stacked nanocone nanostructure is controllably fabricated via mask reconfiguration. This multiscale nanostructure exhibits significant plasmonic properties of active light modulation on the nanoscale and the ability to position the hottest spots on the top surface, along with good performance in surface-enhanced Raman scattering.

The average catalytic activities of the carboxyl groups attached to the carbocatalysts differed. These differences were attributed to variations in the pKa values of the carboxyl groups induced by the electronic effects of the nitro groups.

A versatile strategy involving the careful sulfuration of as-prepared cavity-free core/shell nanocrystals (NCs) or metal-oxide NCs followed by phosphine-initialized cation-exchange reactions was demonstrated for preparing novel metal@semiconductor and metal oxide@semiconductor (II-VI) yolk/shell (Y–S) NCs. The geometry, size, and conformations of the core and shell were independently considered. These new Y–S NCs may have unforeseen applications in confined nanoreactors, heterogeneous catalysis, and energy conversion and storage technologies.

Atomic-thickness two-dimensional (2D) multi-metallic single crystalline alloy nanosheets with highly tunable metallic compositions could be synthesized through in situ topotactic reduction of layered double hydroxides (LDHs). The as-obtained alloy nanosheets not only maintained the ultrathin 2D structure, but also inherited the atomic dispersion of the metallic compositions of the LDH precursors.

An enzyme electrode with a solid/liquid/air triphase interface allows sufficient oxygen to diffuse directly from the air phase to the oxidase reaction zone, which means that the oxidase kinetics is no longer limited by the oxygen level and ensures that large amounts of H2O2 are produced for analyte level measurements. The achieved linear detection upper limit is about 25 times higher than that obtained using traditional enzyme electrodes with a solid/liquid diphase interface.

A three-dimensional porous hierarchical carbon quantum dots (CQDs)/Ni(OH)2 nanocomposite was synthesized via the CQD-induced assembly of two-dimensional ultrathin Ni(OH)2 nanosheets. The CQDs functioned as a new type of structure-directing agent. The as-achieved micro-nanostructured CQDs/Ni(OH)2 exhibited excellent electrochemical performance with a high energy density of 57.4 Wh·kg−1 owing to its multilevel hierarchical structures.
