Better microelectronics from coal

https://techxplore.com/news/2024-01-microelectronics-coal.html

"converts coal char into carbon dots connected forming membranes for 2D transistors and memristors... amorphous, so without boundaries between different crystalline regions (less power leakage)... store and represent data by modulating conductive memristor filament formed by electrochemical reactions between pair of electrodes with insulator sandwiched between... low energy consumption enabling high device operating speed  (>2X faster) with low power.... enhanced data storage fidelity and reliability, AI"
