NIOSH – TechConnect Briefs

Comparison of carbon nanotube data collected using two microscopy methods: dark-field hyperspectral imaging and electron microscopy

Currently, the National Institute for Occupational Safety and Health (NIOSH) Nanotechnology Research Center uses a modified version of the NIOSH Manual of Analytical Method 7303 (Elements by ICP) and electron microscopy (either scanning or transmission) [...]

Prevention through Design Concepts for Sustainable Development of Nanomaterials

Hodson L.L., Geraci C.L., NIOSH, US

Nanotechnology has the potential to provide great benefit to society, but it must be developed responsibly. This responsibility involves addressing any adverse human and environmental impacts of the technology associated with engineered nanomaterials. Workers are [...]

Characterization of Screen-Penetrating Aerosol Fibers and Their Alignment in an Electric Field

Ku B.K., Deye G., Turkevich L.A., NIOSH, US

Length classification of airborne fibers, including carbon nanotubes/nanofibers, is a fundamental technology important for toxicology studies of these materials. Fiber toxicity appears to depend on fiber concentration, dimensions (diameter and length) and durability in the [...]

Evaluating nanomaterial exposures in the workplace: A description of the approach used by NIOSH and a summary of findings from 12 site visits

Hodson L.L., Methner M.M., Geraci C.L., NIOSH, US

Health, safety, and environmental issues continue to be a high priority area to be addressed during the commercialization of nanomaterials or nanomaterial-enabled products (Lux 2008). Facilities engaged in the production or use of engineered nanomaterials, [...]
