Anyone using standard, coated paper in conventional printers.

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...

A novel system developed by MIT researchers automatically “learns” how to schedule data-processing operations across thousands of servers — a task...

Question of the Week : Energy
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...
