... CHALLENGES FOR NANOSCALE MANUFACTURING Terry Lowe stressed that manufacturing is likely to be the biggest challenge in commercializing nanodevices and must be embraced, along with R&D, in a comprehensive systems approach. The semiconductor industry is already facing nanoscale issues as complementary metal oxide silicon (CMOS)

From page 16...
... A 300-fold increase in strength can be attained by changing the current density during deposition, which results in the formation of nanocrystals. IIowever, the grain boundaries of nanostructures will increase with extended exposure to elevated temperatures, increasing flaw sizes and thereby reducing strength The increased surface area of nanomaterials means increased reactivity and susceptibility to environmental conditions.
