Characterization of a Vortex Shaking Method for Producing Airborne Glass Fibers for Toxicology Studies

Ku B.K., Deye G., Turkevich L.A., National Institute for Occupational Safety and Health (NIOSH), US

Current fiber measurement techniques arose primarily due to health concerns over asbestos exposure. Fiber toxicity appears to be mostly a function of fiber concentration, dimensions (diameter and length) and durability in the lungs. A fiber [...]

Separating Single-Walled Carbon Nanotubes by Length

Rauwald U., Schmidt D.J., Hauge R.H., Smalley R.E., Ziegler K.J., University of Florida, US

Single-walled carbon nanotubes (SWNTs) have received great attention because of their unique electronic and mechanical properties combined with their chemical stability. Typically, SWNTs are microns in length; however, intermediate lengths between small spheroidal fullerenes and [...]
