In the past century, fossil fuels like petrol and diesel have powered our vehicles, machines and in fact, our world! But the era of these fuels is coming to an end; all our petroleum reserves are soon ending, and the increasing pollution due to these fuels is making the world sick. Now, our hope lies in biofuels—fuels produced by organic wastes that are renewable and eco-friendly, unlike fossil fuels.
Researchers have built two-dimensional materials-based transistors and used them to design ultra-low power artificial neuron circuits for autonomous robots.
