Electrified charcoal ‘sponge’ can soak up CO2 directly from the air
Researchers have developed a low-cost, energy-efficient method for making materials that can capture carbon dioxide directly from the air.
Mess is best: disordered structure of battery-like devices improves performance
The energy density of supercapacitors – battery-like devices that can charge in seconds or a few minutes – can be improved by increasing the ‘messiness’ of their internal structure.
Low-cost battery-like device absorbs CO2 emissions while it charges
Researchers have developed a low-cost device that can selectively capture carbon dioxide gas while it charges. Then, when it discharges, the CO2 can be released in a controlled way and collected to be reused or disposed of responsibly.
