Directed Assembly of Anisotropic Particles - Fundamentals and Energy-related Applications

submitted by: RASEIBoulder
Summary: Spherical colloids with isotropic properties have been used as building blocks to assemble a variety of 2D and 3D structures in past, such as FCC, HCP, and BCT crystals. Anisotropic particles are, however, more faithful mimics of molecules and atoms because of the anisotropic interactions. Current synthetic methods are versatile and accurate enough to create and tune the anisotropic properties in geometry, chemical composition, surface functionality, and physical properties. In the...

Jean-Claude Bradley présente a la nuit de la liberté au musée de la civilisation a l'université Laval le 8 novembre 2012. Cette présentation de 10 minutes discute des façons de partager la Science Ouverte en général et la Science par Cahier de Laboratoire Ouvert en particulier.

Dietary Selenium Deficiency Partially Rescues Type 2 Diabetes–Like Phenotypes of Glutathione Peroxidase-1–Overexpressing Male Mice

submitted by: xlei
This study was conducted to determine whether dietary Se deficiency precluded overproduction of glutathione peroxidase-1 (GPX1) activity in mice overexpressing (OE) this gene and thus rescued their type 2 diabetes–like phenotypes. A total of 20 male OE and wild-type (WT) mice were fed an Se-deficient (<0.02 mg/kg) diet or an Se-supplemented (0.3 mg/kg as sodium selenite) diet from 1 to 5 mo of age. Dietary Se deficiency eliminated or attenuated (P < 0.05) genotype differences in...

Batteries for Hybridization and Electrification of Vehicles

submitted by: RASEIBoulder
Summary: More than 30% of US energy and 90% of oil consumption are used for roadway transportation. Hybridization and electrification of vehicles on roadways are considered as major strategies for reducing dependence on oil and greenhouse gas and meeting the aggressive fuel economy standards. Hybridization of conventional internal combustion engine vehicles with motors run on electricity from batteries can significantly improve fuel efficiency while electrocution allows switch of the fuel to...

Excitons and Plasmons in Nanoscale Systems

submitted by: RASEIBoulder
Summary: Due to growing populace and standard of living, many terawatts of energy will be needed in the near future. The sun is the largest source of carbon-neutral and renewable energy that we have available and it is the only source that can provide terawatts of energy without depleting rapidly or causing major environmental and climate concerns. To fulfill this role, revolutionary approaches to solar energy conversion are needed that provide energy at very high efficiency at very low...
