4. History

5. History What is Meso/Nano technology? Technology on the scale of atoms -100 pm- up to bio molecular systems as large as cells -10’s mm “Top-down” - achieving increased miniaturization through extension of existing micro fabrication schemes “Bottom-up” - capability to construct functional components, devices, and systems from building blocks of atoms and molecules

6. History During past 9 months, MEL has explored measurements and standards needs of meso and micro-scale manufacturing. Visited 20 companies Conducted and participated in three workshops jointly sponsored with DARPA and NSF Organized informal NIST-wide co-ordinating group for meso/micro/nano scale activities All feedback from these efforts points toward an explodinggrowth of nanotechnology We see a continuum of needs for NIST efforts from the macro-scale to the maso-scale

7. Meso/Nano technology is important! We’ve got to learn how to build materials, devices and machines with the ultimate finesse that life has always used. “… with Meso/nano devices, … you could put all the information needed for some major fraction of your life (the equivalent of 1000 CDs) on your wristwatch. “Mesootechnology has given us the tools to make contact with the world of the molecule and the atom. … The possibilities to create new things appear limitless.

8. Why meso/nano/micro? Exciting diversity of new physical, chemical, mechanical, magnetic, and electronic phenomena Opportunities for dramatically new materials, products, and manufacturing processes Global competitive pressures and the ever increasing demand for faster, smaller, less expensive products

17. Needs Long term: basic science for mesotechnology and nanomaterials, measurements, standards, enabling technology. Short term: critical needs at mesoscale and microscale in metrology, in assembly and packaging, in process science and particularly materials testing and materials data.

18. Conclusion Mesotechnologists are currently studying the dynamics, structure and performance of such mesocatalysts. In the future, mesolasers may replace conventional lasers.
