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.

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.

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.

Anomalous moir¨¦ patterns composed of well-defined linear periodic modulations have been observed on graphene grown on (111) copper. The explanation is that graphene grows on the oxygeninduced reconstructed copper surface and not on the oriented (111) copper as expected.
