Engineers discover new physics principle to break sound absorption barriers in ventilated spaces

In everyday life, designing spaces that both let air flow and absorb sound can be a tricky balancing act. Usually, materials that allow air to pass through—like vents—also let sound escape, making it hard to reduce noise ...

Physics-aware AI algorithm uses Newton's third law to keep simulations stable

A team of EPFL researchers has developed an AI algorithm that can model complex dynamical processes while taking into account the laws of physics—using Newton's third law. Their research is published in the journal Nature ...

New gel electrolyte points to stronger, safer anode-free lithium batteries

Researchers at Columbia Engineering have developed a new gel electrolyte that both improves the lifetime and safety of anode-free lithium batteries, an emerging battery architecture that could dramatically boost energy density ...

Resilient nylon-11 film generates electricity from pressure and survives repeated runovers

RMIT University researchers have developed a flexible nylon-film device that generates electricity from compression and keeps working even after being run over by a car multiple times, opening the door to self-powered sensors ...

3D printing platform rapidly produces complex electric machines

A broken motor in an automated machine can bring production on a busy factory floor to a halt. If engineers can't find a replacement part, they may have to order one from a distributor hundreds of miles away, leading to costly ...

The giant fire tornado that could save our oceans

In the frantic hours following an offshore oil spill, emergency responders face a destructive decision: let the oil spread or ignite it. Once ignited, it creates an "in-situ" fire pool that stops the oil from spreading and ...

Producing bio-methane and CO₂ directly from moist biogas

Thanks to novel flat membranes, biogas can be processed directly and energy-efficiently—even in small plants. In the Bio4Value project, the Fraunhofer Institute for Applied Polymer Research IAP in the Potsdam Science Park, ...

Morphing 3D-printed structures from flat to curved—in space

Because it's costly and cumbersome to transport large structures such as satellite dishes into space, aerospace Ph.D. student Ivan Wu and his advisor, Jeff Baur, at The Grainger College of Engineering, University of Illinois ...

Spray 3D concrete printing simulator boosts strength and design

Concrete 3D printing reduces both time and cost by eliminating traditional formwork, the temporary mold for casting. Yet most of today's systems rely on extrusion-based methods, which deposit material very close to a nozzle ...
