The electrochemical properties of hollow AuAg alloy nanoshells (NSs) with finely tunable morphology, composition, and size are studied. Through their controlled corrosion the generation of a reproducible and tunable electrochemical signal is achieved. Remarkably, the underpotential deposition of Ag+ onto AuAg NSs surfaces is observed and its dependence on nanoparticle morphology, size, and elemental composition is studied, revealing a strong correlation with the relative amount of the two metals.

Oxidation tunes various properties of graphene by changing carbon from sp2 to sp3 type. Such a change is detectable with Raman spectroscopy. Tip-enhanced Raman scattering – a method that combines Raman spectroscopy with scanning probe microscopy can detect localized oxidation and induce oxidation sites on graphene with subnanometer spatial precision.

Polymerization via plasmon-excited hot electrons enables controllable polymer growth with nanoscale precision. The polarization-dependent near-field profile around gold nanoparticles guides the polymer growth into anisotropic features with local selectivity, which significantly advances the control of polymer growth at nanoscale.

Boron and Fe co-doped SrTiO3 (B, F-STO) as a novel photocatalyst has been successfully synthesized for the first time via a single-step sol-hydrothermal process; it exhibits exceptional co-catalyst free photocatalytic activities for CO2 conversion to CH4 and CO and H2O splitting to evolve H2 under UV–vis irradiation.

In this study, we present freestanding nanoporous magnesium as a novel lightweight material with high potential for structural and functional applications. Our synthesis approach is very flexible and we demonstrate that versatile microstructures of the nanoporous magnesium—e.g., nanoscale bicontinuous network, hierarchical, and plate-like structures—can be designed upon the given needs.
