We present ultrathin high-aspect ratio platinum nanowires, which have been electrochemically fabricated from dilute H2PtCl6 solution. The electric field in the vicinity of the growing nanowires was found to be responsible for their straightness.

A commercially amenable synthetic methodology is revealed for developing luminescent carbon nanoparticles from food grade honey with rapid clearance properties for real-time high-resolution photoacoustic imaging.

We provide theoretical predictions of the electronic structure and transport properties in highly defective graphene (HDG). Simulations reveal mean free paths as low as 1 nm and strong Anderson localization phenomena, suggesting HDG as a remarkable prototype of a two-dimensional Anderson insulator.

Low-energy electron microscopy (LEEM) was used to characterize the growth of hexagonal boron nitride (h-BN) on heteroepitaxial cobalt (shown as two opposite triangles). LEEM proves to be a powerful tool in identifying h-BN in the presence of the substrate as well as the determination of the number of h-BN layers.

Self-supported ZnCo2O4 and ZnO/ZnCo2O4 submicron rod arrays have been grown on Ni foil current collectors via an ammoniaevaporation-induced method by controlling the ratio of Zn to Co.The nanostructures are composed of one-dimensional ZnCo2O4 rods and two-dimensional ZnO nanosheet bands perpendicular to the each rod. The hierarchical nano-architecturing strategy demonstrates highly enhanced Li storage capability for Li ion battery electrodes.

We describe a solvent-shift method for the synthesis of water-soluble tri-arm polyethylene glycol chain-coated polyaniline nanoparticles which are able recognize redox activity in tumor cells.

One-dimensional Ag–Li4Ti5O12 nanofibers show enhanced specific capacity, rate capability, and cycling stability compared to bare Li4Ti5O12 nanofibers, due to the Ag nanoparticles (<5 nm), which are mainly distributed at interfaces between Li4Ti5O12 primary particles.

We report manifest spin valve effects from room temperature to 10 K in junctions comprising NiFe electrodes and an interlayer made of double-layer or single-layer graphene grown by chemical vapor deposition. It has been found that a graphene interlayer works not as a tunnel barrier but rather as a conducting thin film between the two NiFe electrodes.
