The Current State of the Global Semiconductor Market

The global semiconductor market has entered an exciting period. Demand for chip technology is both driving the industry as well as hindering it, with current chip shortages predicted to last for some time. Current trends will likely shape the future of the industry, which is set to continue to show

How are Graphene Batteries Made?

How are Graphene Batteries Made?

The primary distinction between graphene-based batteries and solid-state batteries lies in the composition of either electrode. Although the cathode is commonly changed, carbon allotropes can also be employed in fabricating anodes.
