Sub-micrometer meatball-like Au particles provide a very interesting mesoscopic regime in which their optical responses are determined by both the mesoscopic size and the particle's nanoscale surface roughness. The unique optical properties of these mesoscopic particles and particle arrays hold great potential in chem…

Periodic mesoporous organosilica magnetic hollow spheres (PMO–MHS) are synthesized. The particle size, shell wall thickness and saturation magnetization value of PMO–MHS are tunable by varying the ratio of templating agent to magnetic nanoparticles. The high saturation magnetization ensures that these functional mesop…

The use of an ion gel as the gate insulator in polymer TFTs is described. The ion gel is composed of an ionic liquid and a triblock copolymer, and provides a very large specific capacitance, which allows both low voltage operation and high transconductance. Ion-gel-gated TFTs can be switched at a rate of 1 kHz and the…

An investigation of the synthesis of the Sm5(Fe1−xCox)17 (x=0–0.3) phase and its magnetic properties is presented. The Curie temperature of the amorphous Sm5(Fe,Co)17 melt-spun ribbon phase increases with increasing cobalt content of the Sm5(Fe,Co)17 melt-spun ribbon. Heat treatment of amorphous Sm5(Fe,Co)17 melt-spun…

We present our studies of femtosecond photoluminescence of colloidal solutions of CdSe and PbSe nanocrystals, using polychromatic fluorescence upconversion. Ultrafast relaxation processes are observed in both cases upon excitation at 400 nm and 800 nm respectively. Under moderately high excitation densities we studied…

We report a simple technique for the visual determination of a laser light polarization state. The technique is based on a phenomenon occurring when laser light impinges on a particular photopolymerizable mixture sandwiched between two glass plates. After a brief irradiation, some polarization dependent patterns are o…

The wave character of an F-type color center in sodium chloride has been investigated using ab initio band structure calculations in the super-cell approach. Although the F-center, consisting of a zero-charge nucleus and an electron, can be regarded as the most delocalized 'atom', calculations show a localized charact…
