Carbon nanotubes (CNTs) are being researched worldwide to create countless new technologies [1,2], including transistors , solar cells, biomaterials, and hybrid advanced composites [3–7]. Concerns exist about the possibility of nanoscale particle release, notably release of CNTs and catalyst particles , during CNT growth and subsequent handling and(More)
This study investigated airborne exposures to nanoscale particles and fibers generated during dry and wet abrasive machining of two three-phase advanced composite systems containing carbon nanotubes (CNTs), micron-diameter continuous fibers (carbon or alumina), and thermoset polymer matrices. Exposures were evaluated with a suite of complementary(More)
BACKGROUND Source reduction, defined as chemical, equipment and process changes that intervene in an industrial process to eliminate or reduce hazards, has not figured as a front-line strategy for the protection of workers' health. Such initiatives are popular for environmental protection, but their feasibility and effectiveness as an industrial hygiene(More)
