We show that inorganic systems can possess remarkable repair and reconfiguring capabilities under extreme confinement even while in solid state, by studying repair and reconfiguration phenomena in inorganic nanowires encapsulated within single-walled carbon nanotubes. Such processes involve atomic rearrangements in the nanowire to fit changes to their confining template, and are consistent with atomic migration at fractured, ionic ends of the nanowires encouraged by long-range force fields, as well as release-blocking mechanisms where nanowire atoms bind to nanotube walls to stabilize the ruptured nanotube and allow the nanowire to reform.

A binder-free silicon nanoparticle/graphene electrode has been successfully prepared via a facile solution-based procedure, the spincoating technique, by using a stable suspension of Si nanoparticles and graphene oxide in ethanol. By virtue of its unique nanostructure, the as-obtained electrode exhibits a high capacity, a superior rate capability, and an excellent cycle life.

Reversible change in the D to G mode Raman intensity ratio (ID/IG) indicates that the emergence of the D band arises from the reversible and elastic symmetry-lowering of the sp2 bond structure, instead of defect formation.

An appropriately designed dielectric shell boosts drastically the absorption of light in semiconductor nanowire arrays. This lightmanagement strategy has the potential of boosting the performance of nanowire arrays in optoelectronic applications.

A novel one-step aqueous liquid-phase exfoliation method for the preparation of electrochemically functional graphene nanocomposites using natural flake graphite and the polynuclear aromatic electroactive molecule methylene blue with the aid of sonication has been developed. The graphene–methylene blue nanocomposite prepared is exfoliated into single-layer or bilayer states, and sheet or ribbon shapes, and exhibits not only excellent electrochemical conductivity and activity and stability, but also excellent electrocatalytic activity toward hydrogen peroxide (H2O2) and β-nicotinamide adenine dinucleotide (NADH).

We have developed a flexible thermoelectric nanogenerator (TENG) that is based on a Te-nanowire/ poly(3-hexyl thiophene) (P3HT) polymer composite as the thermoelectric material with a positive Seebeck coefficient of 285 μV/K, which can be used as a wearable energy harvester by using human body temperature as the energy source, and can be used a self-powered temperature sensor with a response time of 17 s and a reset time of 9 s.

By tuning the co-adsorption conditions of perylene-3,4,9,10-tetracarboxylic diimide (PTCDI) molecules and Ni atoms, three distinct self-assembled nanostructures from zero-dimensional nanodots over one-dimensional chains to a two-dimensional porous network have been synthesized on the inert Au(111) surface, and investigated using high-resolution scanning tunneling microscopy combined with molecular mechanics and quantum chemical calculations, revealing that the Ni adatoms acquire a negative partial charge through interaction with the substrate and the Ni–PTCDI interaction is entirely electrostatic.
