Researchers have developed a way to wrest the carbon from carbon dioxide and affix it to hydrogen atoms, forming methane - a valuable fuel and industrial feedstock. The method relies on electrolysis and catalysts developed by grafting isolated copper atoms on two-dimensional polymer templates.

Researchers use 3D printed mushroom-like structures to achieve unprecedented control over the speed, path and patterning of bouncing water droplets. This new surface offers advances in self-cleaning, water harvesting and green energy technologies.
