The development of high capacity and long-life lithium-ion batteries is a long-term pursuing and under a close scrutiny. Most of the researches have been focused on exploring electrode materials and structures with high store capability of lithium ions and at the same time with a good electrical conductivity. Thermal conductivity of an electrode material will also have significant impacts on bo...

The design of optimized nanoparticles offers a promising strategy to enable DNA vaccines to cross various physiological barriers for eliciting a specific and protective mucosal immunity via intranasal administration. Here, we reported a new designed nanoparticle system through incorporating anionic liposomes (AL) into chitosan/DNA (CS/DNA) complexes. With enhanced cellular uptake, the construct...

Dear Editors: WE NOTED that nowhere in the issue of Health Physics, March 2009, devoted to “The Capstone Depleted Uranium (DU) Aerosol Characterization and Risk Assessment Study” (Parkhurst and Guilmette 2009) were nanoparticles considered or even mentioned. The smallest particles considered were approximately 0.7 m in diameter (Holmes et al. 2009). Perhaps DU atoms may have entered the brain v...

Implementation of controlled/living radical polymerization in miniemulsion (typically with oil droplet diameter of 20-500 nm) for synthesis of well-defined, polymeric nanoparticles is of particular interest as miniemulsions possess the inherent advantage that ideally each monomer droplet is transformed into a polymer particles(Zetterlund et al., 2008). However, the high energy requirement for m...

Nanomaterials with a characteristic dimension in the range of 1-100 nanometers (nm) are at the leading edge of nanoscience and nanotechnology. In recent years nanomaterials, and specifically metal nanoparticles, have received particular interest in diverse field ranging from material science to biotechnology (Guo et al. 2005, Daniel and Astruc 2004, Huang et al. 2007). Although widespread inter...

Mo carbide nanoparticles supported on ZSM-5 zeolites are promising catalysts for methane dehydroaromatization. For this and other applications, it is important to identify the structure and anchoring sites of Mo carbide nanoparticles. In this work, structures of Mo2Cx (x = 1, 2, 3, 4, and 6) and Mo4Cx (x = 2, 4, 6, and 8) nanoparticles are identified using a genetic algorithm with density funct...

Fungi are important pathogens of vegetables, fruits, cereals, pulses, and other crops. Several management strategies have been used for the control of pathogenenic fungi. Each of these methods has one or other limitations. Due to hazardous effects caused by excessive use of pesticides, scientists in the agricultural field are searching for alternative measures against pesticides. As an alternat...

The behavior and effects of nanoparticles in the environment have up to now been a field where the research was done based on a precautionary approach: what would happen if nanoparticles get into the environment? What would they do there and how would they affect organisms? The occurrence of engineered nanoparticles in the environment has been assumed because ‘‘given the increasing production o...

fluids for various industrial applications because of their excellent thermal performance. This study analytically and experimentally examines the effects of nanoparticle dispersion on the entropy generation of EG–Al2O3 ...
