Monitoring Strategy for Characterization of Airborne Nanoparticles

Niu J., Rasmussen P., Magee R., Nilsson G., Health Canada, CA

A major challenge in monitoring indoor exposures to nanoparticles is the selection and effective use of suitable instrumentation. Comparability, portability, response time, and reliability are important selection criteria in addition to reasonable cost. Amongst these [...]

Pulsed laser generation of clean colloidal metal nanoparticles

Bärsch N., Bartke D., Barcikowski S., Particular GmbH, DE

In contrast to colloidal chemistry, pulsed laser ablation in liquids is a physical process that generates nanoparticles e.g. from precious metals or alloys directly in water or organic solvents. Zeta potential values up to -80 [...]

California’s Efforts to Safe and Responsible Nanotechnologies: Information Call-in from Manufacturers of Nanometals and Oxides

Kang H.Y., California Environmental Protection Agency, US

The nanotechnologies and their applications encompass many areas. However, because of their unique properties, nanomaterials might have the potential to adversely effects to human health and the environment. The potential risks of nanomaterials such as [...]

Effects of Steering in Metal Epitaxial Growth

Amar J., Yu J., University of Toledo, US

Recent experiments on metal epitaxial growth indicate that a high-angle of incidence the long-range attraction of the surface to incoming atoms can lead to steering effects near step-edges which significantly modify the growth and contribute [...]

Atomistic Simulations of Wetting and Spreading in Metal Systems

Webb III E.B., Grest G.S., Sandia National Laboratories, US

Using molecular dynamics (MD) simulations, we examine wetting and spreading in metallic systems as described by the embedded atom method (EAM). We first discuss a common shortcoming of EAM potentials for describing metal surfaces and [...]
