What to know about Ultrafast flash Joule heating significantly reduces MXene manufacturing time

Researchers at Rice University have developed a new method for synthesizing MXenes using ultrafast flash Joule heating and gas-phase etching. This process reduces manufacturing time from several hours or days to under 30 seconds while potentially reducing toxic waste compared to traditional liquid-phase chemical etching.

What happened

Ultrafast flash Joule heating significantly reduces MXene manufacturing time Robert Egan Senior Editor MXenes are two-dimensional materials made of very thin layers of metals, measured on the atomic scale.

Why it matters

They conduct electricity well and have surfaces that can easily interact with other materials, making them excellent candidates for advanced electronic devices, computers and aerospace coatings.

Common ground

The only problem is that, until a recent innovation by James Tour's lab at Rice University, building them required a lengthy, acid-filled process called liquid-phase chemical etching.
