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.

Nanotechnology is spreading its wings

Nanotechnology has been around for a while.  There have been lots of promises resulting in a few solid applications, a number of promising medical advances, and a number of possibilities, which are still in the research stage.  What is often … Continue reading

Move over “Nano”, “Pico” is coming.

Nothing remains on top (or at the bottom) forever.  “Pico” is three orders of magnitude smaller than “nano”.  A rule-of-thumb is that to be able to manufacture or produce something, one must be able to measure to at least an … Continue reading

The Challenges of Reproducible Research

Twice last year, April and November, this blog addressed fake science.  That challenge has not gone away based on recent news articles.  But if one assumes the research is accurately reported and the independent research has differing results, the question … Continue reading

Challenging times ahead thanks to technology

Last month’s blog was about the challenges in determining real scientific research and reports that include falsified or erroneous conclusions.  It is difficult enough to understand results that are presented without complete coverage of the underlying premises.  There are professionals … Continue reading

Faking Science

A portion of this topic was covered in the April 2018 blog, but enough additional material has surfaced that this information needs to be covered again.  The reproducibility issue covered in April is one thing.  The ability to slant results … Continue reading

Nanotechnology and Electronics

The competition for nanotechnology applications in electronic circuitry is meeting manufacturing volume challenges, reliability, and cost.  Until the manufacturing volume can be demonstrated, the reliability can not be evaluated.  Cost will be a function of developing means of high-volume manufacturing.  … Continue reading

Augmented Reality

Previously, I have mentioned how Augmented Reality (AR) could be employed to evaluate nanomaterial properties through being able to switch from 3-D images containing three different parameters to a different view with one or more of the parameters changed.  The … Continue reading

Modeling and Nanotechnology

Modeling is the development of a mathematical representation of an actual or proposed set (group) of interactions that can be employed to predict the functioning of the set (group) under possible conditions.  Interest in modeling has grown since the late … Continue reading

Semiconductor Nanotechnology

What is the state of nanotechnology in creating semiconductors?  As the size of the individual semiconductor components shrink, the current material employed starts to create concerns.  Projections have been made for incorporating nanomaterials, like conductive carbon nanotubes, for interconnects between … Continue reading
