2001 NASA SBIR & STTR Abstract Archives
Glassy carbon grids will be investigated because it offers low sputter-yield, low-CTE, and potentially low machining costs. Phase 1 shall investigate materials and processing of sandwich grid stacks made with carbon facings. Methods for mounting sandwich grids into composite ion engine bodies and for tiling large area grids shall be assessed.

2018-10-22 · Carbon Nanotubes (CNTs) aerosols may appear in occupational environments where they could be inhaled by the workers causing potential health problems. Therefore, investigating the deposition of CNTs in the human airway is important and necessary to assess the health risk posed by the occupational exposure to these particles.
2001 Phase 2 NASA SBIR & STTR Abstract Archives
The motivation for the Phase I effort to use carbon nanotubes for appliion to magnets in space was based on published reports that their current carrying capacity was 10,000 times that of other superconductors and that their mechanical strength was 100 times that of steel on a mass basis.

Because the carbon emitted when plants are burned is equal to that absorbed during growing, it seems self-evident that biomass is a zero carbon (or carbon neutral) fuel. The thinking goes like this: Plants are busy converting CO2 to stored (“sequestered”) carbon in their branches, roots, stems and leaves – so when that plant is burned
