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.

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

Nano Material Properties and the need for multi-dimensional representations

Material properties are “well” defined.  If one goes to a reference source, the various properties of a pure material can be found.  For example, the atomic number of Lithium is 3.  It has an atomic weight of 6.941.  Its specific … Continue reading

Are we missing the important capability of nanomaterials?

Particles with a dimension that is 100nm or less in size are considered nanomaterials.  But, size is not what provides the unique nanomaterial properties that are being observed. Consider the following:  80nm aluminum particles are dangerous as a possible inhalant.  … Continue reading

Two-dimensional materials and moving them into production

There has been more work reporter on 2-D materials, also called atomic level materials.  Typically, this term refers to a sheet of material that is only atom thick with the other two dimensions that extend as far as can be … Continue reading

A Key Nano Device Manufacturing Challenge

The use of “nano” has become commonplace.  Projections are made about creating individual items/molecules/devices at the nano-scale.  There are examples of nano clocks, vehicles, etc.  Given enough effort, funding, and time, it is possible to create a large variety of … Continue reading
