In previous blogs, two dimensional semiconductors have been discussed.  Work at Singapore University of Technology and Design has developed a different approach to solving the issues of very small transistors that will be required for future generations of semiconductors [Ref. … Continue reading →

With the emphasis on nanotechnologies and the emphasis on two-dimensional materials, other areas that are pushing boundaries are often overlooked.  A recent article [Ref. 1] summarizes work done at King’s College London on relieving pain.  Their treatment employs a ultra-low … Continue reading →

Last month, this blog covered some of the challenges of continually shrinking semiconductor geometries and the related difficulties with traditional transistor designs.  This month’s blog explores transistor geometry.  In May 2021, IBM announced a 2nm nanosheet semiconductor technology. [Ref. 1]  … Continue reading →

As semiconductor manufacturing continues the dimensional shrinking process, novel ideas are required to achieve the ability to continue shrinking the dimensions while increasing the performance.  There are some thoughts that this potion of the Moore’s law curve will provide some … Continue reading →

Just prior to the end of June, there were two articles on cement/concrete.  “How to Make a ‘Smarter’ Cement” [Ref. 1] covers reports from Northwestern University’s team that introduced nanoparticles into ordinary cement.  They investigated two types of nanoparticles and … Continue reading →

It has been an interesting month as the country starts coming back to “normal”.  I was fortunate to have the opportunity to “attend” (virtually) a presentation by a University of Texas at Austin professor.  Professor Hugh Daigle provided a very … Continue reading →

The recent past few months have seen a few published articles on 2D materials and their applications.  The pace is picking up. One of the challenges of 2D materials is that the materials need to be incorporated into some other … Continue reading →

Recently, the term “Cost of Ownership” has been appearing in various papers about a number of topics, including wind power and electric vehicles among others.  The Wall Street Journal had an article comparing the emissions cost of a gasoline car … Continue reading →

Fifteen years ago (2006) there was a white paper published [Ref. 1] that addressed the need to create a structured approach to the handling and usage of nanomaterials.  As stated in the September 2013 blog on Nano-Safety, the primary issues … Continue reading →
