Building better catalysts to close the carbon dioxide loop

The best way to stave off the worst effects of climate change is to reduce CO2 emissions around the world. And one way to do that, says Zhongwei Chen, a professor in the Department of Chemical Engineering at the University ...

Cubes outperform spheres as catalyst particles

To date, nanoparticles as catalysts for green hydrogen have been like rowers in an eight: researchers could only measure their average performance, but couldn't determine which one was the best. This has now changed following ...

The Donnan potential, revealed at last

The Donnan electric potential arises from an imbalance of charges at the interface of a charged membrane and a liquid, and for more than a century it has stubbornly eluded direct measurement. Many researchers have even written ...

Earth's inner core may be oxygen-rich

Oxygen is the key substance for life and one of the most abundant elements in the Earth. However, it's still unknown whether oxygen is present (and in which form it may exist) in the inner core, which is composed of almost ...
