Shape-controlled CuCl crystallites exposing different proportions of {111} and {110} crystal planes have distinctive catalytic properties for aniline coupling, which serves as evidence that {111} crystal planes have better catalytic activity than {110} planes.

In the aqueous-phase synthesis of Pd nanobars, nanocrystal growth at early stages of the reaction is dominated by particle coalescence, followed by shape focusing via recrystallization. The as-synthesized Pd nanobars contain several types of surface defects such as an adatom island, a vacancy pit, and steps.

The band gap of graphene nanoribbons can be engineered by strain, especially in the case of uniaxial strain applied to an armchair graphene nanoribbon. The band gap is roughly inversely proportional to the width of ribbon, and increasing the strain modulates the band gap in a periodic fashion.

The topotactic transformation from NiFe-layered double hydroxide precursors to NiFe2O4/NiO nanocomposites through high-temperature treatment leads to an interfacial nanosystem with greatly enhanced magnetic stability. The blocking temperature of the final system is 380 K, about 100 K higher than a similar system prepared by calcination of a precursor prepared by a traditional coprecipitation method.

Magnetic Fe2P nanowires and Fe2P@C core@shell nanocables, exhibiting interesting ferromagnetic–paramagnetic transition behaviors with high blocking temperatures, have been synthesized from separate reactions of triphenylphosphine (PPh3) with iron powder and a molecular precursor, ferrocene (Fe(C5H5)2), respectively, in vacuum-sealed ampoules at temperatures of 380–400 °C.

Isotopically-modified single-walled carbon nanotubes have been synthesized and employed for biomedical Raman imaging. The five intense labels allow facile multiplexing in the near-infrared region, with minimal background interference.
