Optical Properties of Individual Nano-Sized Gold Particle Pairs
… affects the SCS even in such a way that a two-particle system may show both a blue- and redshifted SCS, depending only on the distance between the two MNPs. The maximum distance for this effect is the coherence length of the illumination source – a fact of importance for SCS-based experiments …

The Diversity and Function of Bacteria Enriched from Gold Particles: Understanding Bacterial Contribution to Biogeochemical Cycling of Gold
In natural environments, gold is dissolved (oxidized), dispersed, and reconcentrated (reduced and aggregated). Collectively, these processes constitute the biogeochemical cycle of gold, which can be catalysed by bacteria, and have been interpreted from the characterisation of gold particles that …

Electronica Devices and Interface Strategies for Nanotechnology
… Next, electrical characterization of gold nanocrystal capacitors showed significant increases in the flat band voltage shift as the gold particle density increased. The density scaling of gold and palladium films was investigated revealing a linear dependence of gold on decreasing …

Static and ultrafast optical properties of nanolayered composites : gold nanoparticles embedded in polyelectrolytes
In the course of this thesis gold nanoparticle/polyelectrolyte multilayer structures were prepared, characterized, and investigated according to their static and ultrafast optical properties. Using the dip-coating or spin-coating layer-by-layer deposition method, gold-nanoparticle layers were …

Gold(I) complexes and co oxidation catalysts
Isonitrile gold(I) nitrates, (RNC)AuNO₃ (R = Buᵗ, Et or Xy) have been prepared and fully characterised. These join the rare set of gold(I) species exhibiting ligation to oxygen and are the first examples of gold(I) bonded to both carbon and oxygen. Molecular aggregations of the monomeric units were …
