A thermodynamic model for the shape and stability of twinned nanostructures
Article Abstract:
A thermodynamic general analytical model is presented for the investigation of nanomaterials of arbitrary shape and with any configuration of planar defects. This model is tested for the case of twinning in unsupported gold nanocrystals and nanorods, and the results are found to be in excellent agreement with experimental observations and explicit computational studies.

Equilibrium morphology of face-centered gold nanoparticles >3nm and the shape changes induced by temperature
Article Abstract:
The first principle calculations and a thermodynamic model are used to investigate the morphology of gold nanoparticles in the range 3-100nm. Results show that the equilibrium shape of gold nanoparticles is a modified truncated octahedron and the (size dependent) melting of such particles is preceded by a significant change in the nanoparticle's morphology.

Ultrafast photosynthetic reduction of elemental sulfur by Au nanoparticle-loaded Ti[O.sub.2]
Article Abstract:
An ultrafast Au/Ti[O.sub.2] photosynthetic reduction of elemental sulfur [[S.sub.8]] to [H.sub.2]S in ethanol solutions is reported. A kinetic analysis has shown that the increase in the rate of reaction with decreasing nanoparticles (d) results from the improvement of the charge separation efficiency.
