Angstron Materials

Breakthroughs In Nano Graphene Technology

Angstron Materials and Nanotek Instruments’ co-founders Dr. Bor Jang and Dr. Aruna Zhamu are ranked among the top five in the world for their development of intellectual property publications for graphene. Gridlogics, a patent analytics solutions specialist that publishes Patent iNSIGHT Pro, ranked Siemens AG with the highest total (89) for graphene-based IP publications followed by Jang with 42 and Zhamu with 39.  Filings by Jang and Zhamu cover a range of new technologies including new compositions, processes, and applications of both single-layer and multi-layer graphene, collectively referred to as nano graphene platelets.  Angstron Materials is the world’s largest producer of nano graphene platelets.
