Standard on Nanomanufacturing Terms and Definitions Published by ISO

National Nanomanufacturing Network - April 25, 2014 - 3:46am
The International Organization for Standardization (ISO) standard on Nanomanufacturing Terms and Definitions was published in December 2013. The concept database for ISO/TS 80004-8:2013 “Nanotechnologies—Vocabulary—Part 8: Nanomanufacturing Processes (Published December 15, 2013) can be accessed at https://www.iso.org/obp/ui/#iso:std:iso:ts:80004:-8:ed-1:v1:en:term:3.13 (https://www.iso.org/obp/ui/#iso:std:iso:ts:80004:-8:ed-1:v1:en:term:3.13). This Technical Specification gives terms and definitions related to nanomanufacturing processes, forming one part of multi-part terminology and definitions documentation covering the different aspects of nanotechnologies.The NNN has participated in this standards activity, with the InterNano taxonomy (http://www.internano.org/component/option,com_internanotaxonomy/Itemid,177/) database contributing nanomanufacturing process terminology towards this standard. The NNN continues to contribute to similar activities supporting the necessary infrastructure for a sustainable nanomanufacturing roadmap.

Making graphene work for real-world devices

National Nanomanufacturing Network - April 24, 2014 - 9:07am
Graphene, a one-atom-thick form of the carbon material graphite, has been hailed as a wonder material--strong, light, nearly transparent and an excellent conductor of electricity and heat--and it very well may be. But a number of practical challenges must be overcome before it can emerge as a replacement for silicon and other materials in microprocessors and next-generation energy devices.One particular challenge concerns the question of how graphene sheets can be utilized in real devices. When you fabricate devices using graphene, you have to support the graphene on a substrate and doing so actually suppresses the high thermal conductivity of graphene, said Li Shi, a professor of mechanical engineering at The University of Texas at Austin, whose work is partially funded by the National Science Foundation (NSF).
