Are Emerging Applications of Carbon Nanotubes Safe?

Sharma R., Shetty K., Liang R., Chen C-J., Florida State University, US

Carbon nanotubes are emerging as potential tools in drug delivery nanocarriers to target specific cell types and carbon cages filled with metal molecules may improve MRI microimaging. The present paper reviews the current state of [...]

Adsorption/Desorption of Cd by Titanium Dioxide Nanoparticles and Sediment Particles as well as Their Facilitated Bioaccumulation of Cd into Carp

Zhang X., Chen Y., Sun H., Crittenden J.C., Arizona State University, US

There are increasing concerns about the health and environmental impact of nanomaterials. The study of Sun et. al 2006 provided the evidence of facilitated bioaccumulation of As(V) in carp in the presence of titanium dioxide [...]

Detection, Measurement and Toxicology of Semiconductor Nanocrystals in Ceriodapnia dubia

Ingle T., Hannigan R., Buchanan R., Bouldin J., Arkansas State University, US

Engineered nanomaterials differing in size, shape, surface area and composition are used in research, industrial, and consumer applications. Because of their unique structure and size the need exists for toxicological profiles of nanoparticles as a [...]

Methods for the Prediction of Nanoparticle Fate, Transport and Receptor Exposure in an Aqueous Environment

Mackay C.E., Gray M.N., Reinert K., Sellers K., AMEC, US

The development and applications of nanomaterials have presented a unique problem to environmental scientists and risk assessors. Until now, the models and paradigms used to predict the behavior of chemicals in the environment and thereby [...]

Theoretical Study of the Reaction between OH Radicals and Formaldehyde adsorbed on Small Silica Clusters

Iuga C., Vivier-Bunge A., Universidad Autónoma Metropolitana, MX

Heterogeneous reactions of atmospheric gases on aerosol particles may play an important role in atmospheric chemistry. However, the kinetics and mechanisms of adsorption and reaction of atmospheric gases on aerosol surfaces are not well understood. [...]

Characterization on Dioxin Emission of TiO2 Nanoparticle-Encapsulating Poly(vinyl chloride) (TEPVC) compared to conventional PVC

Yoo H., Kim S-H, Lee A.R., Kwak S-Y, Seoul National University, KR

In our previous study, we first prepared TiO2 nanoparticle-encapsulating poly(vinyl chloride) (TEPVC) aiming at breakthrough to enhance the dispersibility of TiO2 nanoparticles in PVC matrix to maximize catalytic activities of TiO2 nanoparticles. The present study [...]

A Line Force Model to Measure the Strength of Polydimethylsiloxane (PDMS)-to-PDMS Bonding in Blister Tests

Lin P-T, Lu Y-W, Rutgers University, US

Bonding is an important technique in microelectronics and Microelectromechanical Systems (MEMS). Especially, bonding two pieces of polydimethylsiloxane (PDMS) to make micro devices was widely used in micro actuators and BioMEMS. The PDMS bonding, however, lacked [...]

Effects of interface on the physical properties of nanoparticle-filled composites

Jang K.H., Kim B.C., Hanyang University, KR

The effects of interface affinity on the rheological responses of nanoparticle suspended polymer solutions were investigated. The polarity on rheological properties of zinc oxide (ZnO) nanoparticle filled-polymer solution was investigated for polyacrylonitrile (PAN) and polystyrene [...]
