A fluid-magnetic solution for sorting plastic waste

With the ever-increasing worldwide mass production of plastic, the inefficiency of current plastic recycling strategies has raised several environmental, societal, and economic concerns. Magnetic density separation (MDS) ...

NASA to begin high-voltage ground testing on all-electric X-57

NASA is set to start high-voltage functional ground testing of the agency's first all-electric X-plane, the X-57 Maxwell, which will perform flights to help develop certification standards for emerging electric aircraft. ...

Image: Greener way to get satellites moving

A sustained test firing of a 'green' satellite thruster at Poland's Institute of Aviation, intended as a future alternative to today's hydrazine-based apogee engines, typically used by telecommunication satellites to maneuver ...

The perfect recipe for efficient perovskite solar cells

They have improved a process for vertically depositing a solution made from an inexpensive perovskite solute onto a moving substrate below. Not only have they discovered the crucial role played by one of the solvents used, ...

Attachable skin monitors that wick the sweat away

A new preparation technique fabricates thin, silicone-based patches that rapidly wick water away from the skin. The technique could reduce the redness and itching caused by wearable biosensors that trap sweat beneath them. ...

Scientists use smartphone gyroscopes to sync time across devices

Skoltech researchers have designed a software-based algorithm for synchronizing time across smartphones that can be used in practical tasks requiring simultaneous measurements. This algorithm can essentially help turn several ...

Less-wasteful laser-cutting

Laser-cutting is an essential part of many industries, from car manufacturing to construction. However, the process isn't always easy or efficient: Cutting huge sheets of metal requires time and expertise, and even the most ...
