Environmental Life Cycle Assessment for a Carbon Nanotube-Based Printed Electronic Sensor Platform

Chappell M.A., Shih W-S, Bledsoe J.K., Cox C., Janzen D., Gibbons S., Patel R., Kennedy A.J., Brame J., Brondum M., Diamond S.A., Coleman J., Edwards D., Steevens J.A., U.S. Army Engineer Research & Development Center, US

Here, we describe efforts to characterize the potential environmental impact associated with the manufacture of a newly developed printed electronic temperature sensor using environmental life cycle assessment (Eco-LCA). The sensor is composed of a specialized [...]

Advancements in Microelectronics-Grade Carbon Nanotube Materials for NRAM® Device Manufacture and Analysis of Carbon Nanotube Mass in End User Devices

Lamb J.E., Gibbons S., Trichur R., Jiang Y., Mangelson K., Kremer K., Janzen D., Brewer Science, Inc, US

Providing materials for use in semiconductor manufacturing is challenging due to the extreme quality levels required for low metal ion and defect levels. This challenge is much greater for suppliers of materials containing long, high-aspect-ratio [...]

Outwitting the uncertainty of nanotechnology risks through environmental life cycle assessment

Steevens J., Chappell M., Janzen D., Edwards D., Shih W., US Army Engineer Research and Development Center, US

The goal of this study was to evaluate a carbon nanotube (CNT) product in terms of life cycle phases representing points where resources are expended and emissions are created. The study described here is important [...]
