Ranjith retired from 3M Canada as a Senior Physicist/Specialist after leading
research in multiple areas for 27+ yrs. He has conducted R&D in many diverse
areas such as digital x-ray imaging, electrically conducting adhesives, UV
photocatalysis for air purification, force sensors, water purification, sensors for
contaminants in water, Li ion battery materials, and nano scale coatings in a
variety of commercial applications. He is the inventor of 3M graphene-likecarbon
(GLC) coatings. His work has resulted in 190 invention submissions at
3M Company, and 21 issued US patents, and 35 peer-reviewed journal
articles. He has won multiple 3M Corporate Circle of Excellence and
Innovation awards, and won the best paper of session in 36th International
Symposium on Microelectronics (IMAPS), Boston in 2003. A common thread of
his research interest and experience in industry and academia has been on
applications of two dimensional (2D) materials. Now he is fully engaged in R&D
on graphene related applications with HydroGraph Clean Power Inc, an
innovative graphene company in Canada.
Two-dimensional materials and applications
I will describe my industrial experience in developing applications of twodimensional
nano materials leading to both new processes and product
development. I will then describe a new, bottom-up, commercial method of
producing graphene in bulk powder form, called Synthetic Detonated
Graphene (SDG). SDG is a new form of nano material discovered at the
Physics Department of Kansas State University. HydroGraph has
commercialized SDG for multiple applications. The process of making SDG
is a very versatile: it is a gas-phase, clean, energy efficient and green
process. Hydrogen gas can also be manufactured economically with the
same detonation process and with a low carbon foot-print compared to all
other existing manufacturing processes. Both graphene and hydrogen will
become very important materials that drive the transition from fossil-fuel
based economy to a sustainable, clean, green economy. Our goal is to help
that transition by commercializing materials manufactured with
environmentally friendly sustainable processes.
