Wrinkles and crumples boost metal oxides

Researchers at Brown University, Providence, R.I., found a new method for making ultrathin metal-oxide sheets containing intricate wrinkle and crumple patterns. The textured metal-oxide films have better performance when used as photocatalysts and as battery electrodes.

Predicting how bonds break

Scientists at the University of Chicago, New York University, and Leiden University could eventually help create materials that resist breaking or crack in a predictable fashion.

Scooters take you for a ride (with video)

In the spring, more than 100 visitors took rides on an autonomous mobility scooter in a trial of software designed by researchers from MIT and colleagues in Singapore.
