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.

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

Changes in Nanotechnology Perspectives

There are announcements about new findings or new concepts in nanotechnology that may not appear a “big” changes.  Typically, the definition of nanomaterials is: For a material to be called nanomaterial, its size must be smaller than 100 nm in … Continue reading

Medical Nano

The development of nanotechnology in medicine is a longer-term process than nanotechnology in general.  The reason is that the application of any technology, device, or medicine to humans has an involved process with many steps that require a long time … Continue reading

Coming Attractions?

It is always a challenge to write an end-of-year blog.  The question is what to focus on. Highlights of 2017? Or possible coming items in 2018?  Or maybe some of both.  There has been some expansion of graphene manufacturing capabilities … Continue reading

Semiconductors and Nanotechnology

There is a rule developed by Gordon Moore that projected the increase of density of semiconductors.  For many years the path “Moore’s Law” predicted (a doubling of density roughly every 18 months) has been followed.   The driver for this pattern … Continue reading
