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.

Two-dimensional materials’ research opening new opportunities

There have been some interesting reports in the last year that indicate there is a growth in interest and a branching out in nanomaterials research.  In the pursuit of increasing the capability of better batteries, researchers are investigating many different … 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

Technology Roadmaps

The term “roadmap” implies something (a document, a pictorial representation, etc.) that provides the guidance to get from one point to another.  Due to the lack of a direction in developing large scale nanotechnology applications (author’s opinion), there is a … Continue reading

Structured Materials

There is more reporting of “structured” materials.  The terminology employed to define “structured” overlaps with “metamaterials”.   First metamaterials are typically an engineered assembly of various elements that are constructed in specific atomic structure arrangements to create non-natural occurring combinations and … Continue reading

Current Challenges in Science – Scientific Rigor

The accuracy of “scientific” research has recently reappeared in the press.  A previous blog (February 25, 2015) addressed the implication of erroneous published medical research results.  An earlier blog (July 17, 2014) discussed falsifying peer review processes.  The concern is … Continue reading
