Rose-Inspired Device Collects and Purifies Water

A new device, inspired by a rose, inexpensively collects and purifies water. The device is a new approach to solar steaming for water production — a technique that uses energy from sunlight...

Question of the Week : Power
Does Snow Have Power Potential?

A 2019 Tech Briefs story demonstrated a plastic-like, flexible nanongenerator that creates electricity from falling snow.

Briefs : Energy
Low-Cost Thermoelectric Material Works at Room Temperature

The widespread adoption of thermoelectric devices that can directly convert electricity into thermal energy for cooling and heating has been hindered, in part, by the lack of materials that are both inexpensive and highly efficient at room temperature. A new material was developed that...
