This material absorbs more than 99% of the light that strikes it, making it useful in applications ranging from solar energy to astronomy.
Caffeine coating gives fuel cells a boost
Modifying hydrogen fuel cells with caffeine helped protect them from degradation, resulting in up to 11-fold increase in activity.
Photoacids capture and release carbon with the flick of a switch
Scientists develop a light-driven carbon capture system using photoacids, creating an energy-efficient method to remove atmospheric carbon dioxide.
A “methane cleaner” to slash emissions
The new device pulls methane out of the air and could help tackle emissions from low-concentration sources, like livestock farms.
Fitness trackers powered by sweat
The generator harnesses energy from water and is built with a fiberform material derived from the straps of disposable medical masks.
Scientists harvest electricity from the movement of molecules
A new frontier in clean energy may be on the horizon with nanoscale generators that capture electricity from molecules.
Self-powered nanosensor to transform vehicle safety
Drawing power from the electrical fields of nearby objects, this nanosensor enhances vehicle safety and slashes energy consumption.
Turning plastic waste into low-cost hydrogen fuels
A flash heating technique breaks down plastic waste and converts it to pure hydrogen and graphene with significantly less emissions and at a low cost.
Thin film improves “usable light” needed to grow microalgae on industrial scales
A textured film maximizes sunlight by generating an increased amount of red light, reducing the costs of algae production on a significant scale.
Making ammonia from thin air
A one-step synthesis of ammonia without thermal, electrical, or solar input could help replace energy-intensive Haber Bosch.
