About Walt

I have been involved in various aspects of nanotechnology since the late 1970s. My interest in promoting nano-safety began in 2006 and produced a white paper in 2007 explaining the four pillars of nano-safety. I am a technology futurist and is currently focused on nanoelectronics, single digit nanomaterials, and 3D printing at the nanoscale. My experience includes three startups, two of which I founded, 13 years at SEMATECH, where I was a Senior Fellow of the technical staff when I left, and 12 years at General Electric with nine of them on corporate staff. I have a Ph.D. from the University of Texas at Austin, an MBA from James Madison University, and a B.S. in Physics from the Illinois Institute of Technology.

New Developments in the World of Nano

Tools: In previous blogs I have mentioned that to truly work at a small scale, one needs to be able to measure to at least a dimension that is one-tenth the size of what you are measuring.  Ideally, the capabilities … Continue reading

Is that all there is?

With apologies for using the title of a Peggy Lee song from the 70s, this reference is to nanotechnology.  There are continually more interesting findings as researchers move into smaller and smaller particle sizes.  The question really is what happens … Continue reading
