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. The two sister companies hold over 150 issued or pending patents related to graphene production, optimization, and utilization. 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.
