Nanostructured materials have received tremendous attention as potential Li-ion electrodes due to their unique size-dependent properties. In this review, we highlight a number of significant recent examples of nanostructured architectures as potential drivers of next-generation Li-ion batteries.

Half-metallicity of AlN nanoribbons can be tuned by both external applied electric fields and uniaxial strain in a spin-selective and self-doping process.

A false electrocatalytic effect is manifested when an inert electrode surface is modified with nano- or micro-particles so that the total electroactive surface area of the particles is greater than the geometric area of the electrode.

Manganese phthalocyanine (MnPc) molecules anchored on an Au(111) surface are used to efficiently collect and pin hydrogen molecules. The hydrogen molecules self-assemble into ordered two- dimensional (2D) clusters, exhibiting bias-dependent topography and spatial-dependent conductance spectra. The 2D H2 clusters are in an interfacial phase between 2D solid and 2D fluid.

Hierarchical 3D mesoporous C@Si@graphene foam (C@Si@GF) nanocomposites have been successfully synthesized by a thermal bubble ejection assisted chemical-vapor-deposition and magnesiothermic reduction method. When employed as anode materials for lithium ion batteries, C@Si@GF nanocomposites exhibited superior electrochemical performance including a high specific capacity of 1,200 mAh/g at the current density of 1 A/g, excellent high rate capabilities and an outstanding cyclability.

Large arrays of chemical vapor sensors based on chemical vapor deposition (CVD) graphene field effect transistors functionalized with single-stranded DNA are demonstrated down to parts-perbillion concentrations. Chemically similar analytes, including a series of carboxylic acids, and structural isomers of pinene are distinguished and evidence is shown for the important role of electrostatic chemical gating as a sensing mechanism.

Vertically aligned anatase TiO2 nanotubes with hexagonally shaped open-ends can be fabricated using a hydrothermally grown ZnO nanorod template and a chemical capping material that allows for easy peeling of the TiO2 top cover during the selective wet-etching of the ZnO core, as shown above taken in sequential time order.

We report on the non-aqueous synthesis of Th1–xUxO2 nanocrystals by the controlled hot co-injection of thorium acetylacetonate and uranyl acetate in a highly coordinating organic medium. The synthesis, structure and magnetic properties of the as-prepared nanocrystals are investigated.
