Giant planets can have very different atmospheres, according to NASA’s Webb telescope

April 3, 2023

A planet called Smertrios, or HD 149026b, is about three times hotter than the rocky surface of Venus, the hottest planet in our solar system.

Distant planet called Smertrios is very different from Jupiter and Saturn, UChicago-led study finds. It is about three times hotter than the rocky surface of Venus, the hottest planet in our solar system.

UChicago scientists discover easy way to make atomically thin metal layers for new technology

March 24, 2023

A scanning electron microscopy image reveals the beautiful shapes of tiny structures known as MXenes, which are of interest to scientists for new devices and electronics but were previously hard to create. These were grown with a new easier and less toxic

A new breakthrough by UChicago scientists shows how to make MXenes far more quickly and easily, with fewer toxic byproducts. Researchers hope the discovery, published March 24 in Science, will spur new innovation and pave the way towards using MXenes in everyday electronics and devices.
