Transistors inside modern computer chips are several nanometers across, and switch on and off at hundreds of gigahertz. Organic electrochemical transistors, made for biodegradable applications, are milimeters in size and switch at kilohertz rates. Then, the remaining cellulose-based structure was coated with a conducting polymer.

ARPA-E awards $175M to 68 novel clean energy OPEN 2021 projects

Green Car Congress

The MIT will develop a new generation of power electronics based on vertical gallium nitride (GaN) superjunction diodes and transistors that can vastly exceed the performance of today’s GaN power devices. The system takes three main inputs: ambient air, water, and a sustainable energy source, and produces butanol with high selectivity.
