Cadmium selenide nanocrystals were coated with a gold shell which could be transformed to small clusters by additional reducing agents reports Christian Klinke and co-workers from Germany and Spain in this Communication. By varying the conditions of gold deposition they were able to tune the gold domain size and gain important information on the role of surface chemistry in heteronanoparticle synthesis and seed reactivity, both of which are crucial points regarding the chemical design of new materials for photocatalysis and optoelectronic applications.

DOI: 10.1039/C0JM02606A, Paper
In this paper a team from Inha University in South Korea report the successful application of submicron-sized monodispersed TiO2 spheres (SPs) with high porosity as the light scattering layer of dye-sensitized solar cells. This resulted in an increase of the photovoltaic conversion efficiency from 6.92 to 9.04% when using the SP which gave the highest light scattering efficiency.
