Uniformly Distributed Metal Nano-particles in Various Sized Porous Catalytic Supports by NPP Process

Lee C., Lee J-H., Lee C., Lee J-H., Kang B.K., Kaji H., Hayashi M., Koh S.K., GL Materials, KR

2~10 nm sized metal nano-particles were uniformly loaded in porous activated carbon (AC) support and 10~100 nm sized metal nano-particles were completely covered on the surfaces of air flow channels of porous ceramic monolith. Metal [...]

Single-walled carbon nanotubes induce fibrogenic response by promoting fibroblast-to-myofibroblast transition: An in vitro molecular toxicity pathway based risk assessment

He X., Wang L., Rojanasakul Y., West Virginia University, US

Several reports have shown that single-walled carbon nano tubes (SWCNT) caused lung fibrosis in rodents. The molecular mechanisms that govern SWCNT lung toxicity remain largely unaddressed. Our results indicate that SWCNTs induced ROS and mitochondrial [...]

Carbon Combustion Synthesis of Lithium Cobaltate

Hobosyan M., Mamyrbaeva Y., Martirosyan K.S., University of Texas at Brownsville, US

We recently developed a novel process Carbon Combustion Synthesis of Oxides (CCSO) to rapidly produce high purity, submicron, porous powders of complex oxides. The crystalline LiCoO2 nanoparticles were synthesized by carbon combustion synthesis, and characterized [...]

Methods of colloid vibration imaging for characterisation of nano-particle suspensions

Wang M., Hosseini M., Bramson L., Khan J.I., University of Leeds, UK

This paper addresses various aspects in the development of the new imaging technique, colloid vibration potential imaging. Two theoretical models are introduced, including an extended (2D) slab model and a 3D electric dipole model. These [...]

Spherically symmetric oxidation model of aluminum nanoparticles

Ramazanova Z., Zyskin M., Martirosyan K.S., University of Texas at Brownsville, US

Kinetics of oxidation of metal nanoparticles acquired practical importance with rapidly developing nanoenergetic systems and materials. Nanoenergetic thermites include mixtures of Al and metal oxides in nanoscale. Our research focuses on modeling aluminum combustion in [...]

Innovative Use of Ultrasound in the Production of High-Performance Coatings

Hielscher K., Hielscher Ultrasonics GmbH, DE

The metal oxide nanoparticles include nano-sized zinc oxide, titanium oxide, iron oxide, zirconium oxide and cerium oxide, as well as mixed metal compounds, such as indium tin oxide, zirconium and titanium. For the color, paint [...]

Modulating the Near Infrared Reflective Properties of Metal Oxides for Surface Coating Applications

Nidhin M., Sangeetha S., Radhika S., Sreeram K.J., Nair B.U., Central Leather Research Institute (CSIR), IN

A colorant which is able to reflect a major portion of the near infrared radiation is today known as cool colorant. These colorants when coated on roof tops, automobiles, leather etc. reduce the demand for [...]
