In the June 2018 blog both the International Technology Roadmap for Semiconductors and the current International Roadmap for Devices and Systems were mentioned in a discussion of the need for roadmaps [Ref. 1].   As the semiconductor industry moves into the … Continue reading →

Nanotechnology is interesting.  When one starts to think that we have a reasonable knowledge of particle behavior, someone finds something new and interesting.  A basic assumption in thermodynamics is that objects change temperature (warming up or cooling down) at the … Continue reading →

Last blog mentioned metallic hydrogen at a very small level.  As the computational power increases, we are able to examine (theoretically at least) the behavior of various materials.  There is a significant amount of effort being directed at the investigation … Continue reading →

A couple thoughts on Hydrogen.  This might be old news to some, but two Harvard scientists have created metallic hydrogen [Ref. 1] by employing extreme pressures. This material is predicted to be metastable.  This implies that when the pressure is … Continue reading →

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 →

In doing research for an upcoming published paper, I ran across an interesting article.  In September 2019, a research article was published that postulated the worst case situation for a worldwide pandemic, of unknown origins, might have a devastating impact … Continue reading →

As the world starts to come out of the Covid–19 shutdown, there are many things that will be required for research organizations to address prior to beginning their research again. Businesses have a similar but different process that needs to … Continue reading →

I’ve written about validating scientific findings previously.  With the current COVID-19 (coronavirus) situation, there have been numerous published claims of various “facts”, which are based on models.  It was only a couple of months ago that the news carried projections … Continue reading →

As this month’s blog is being written, the US has a “shelter-in-place” directive that has been extended through the end of April.  There are many reports of possible medical treatments that may mitigate the current Covid-19 virus.  Most of the … Continue reading →
