Rise of the rice robots—creating active smart materials

Rice becomes weaker when compressed quickly, while staying stronger under slow pressure—a discovery enabling scientists to design a new material that could be used to build "soft" robots that change stiffness automatically ...

Sodium-ion batteries lean heavily on lithium-ion expertise, patent analysis suggests

Researchers from the University of Münster, ETH Zurich, Stanford University, and the Fraunhofer Research Institution for Battery Cell Production (FFB) used AI-supported patent analysis to show how strongly battery technologies ...

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 ...

A heatshield for 'never-wet' surfaces: Engineers repel even near-boiling water with low-cost, scalable coating

Superhydrophobic surfaces—those famously "never-wet" materials that make water bead up and roll away—have a stubborn weakness: hot water. Once temperatures climb above roughly 40 degrees Celsius, many superhydrophobic ...

A new way to study how cannabis use impacts safe driving

As marijuana legalization expands across the U.S., it is outpacing research on the impact of cannabis use behind the wheel. Researchers at the Virginia Tech Transportation Institute (VTTI) recently spent two years collecting ...

Engineering

Tackling uplift resistance in tall infrastructure sustainably

Tall structures like radio towers experience high wind loads that generate uplift forces at their foundations, a challenge that is increasing burden, as natural occurrences like typhoons and tornadoes become more frequent ...

Engineering

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 ...

Engineering

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 ...

3D-printed steel capsules endure nuclear reactor testing

The Department of Energy's Oak Ridge National Laboratory set a new milestone in nuclear component innovation, successfully testing two 3D-printed stainless steel experimental capsules at the lab's High Flux Isotope Reactor, ...

Elephant robot demonstrates bioinspired 3D printing technology

A cheetah's powerful sprint, a snake's lithe slither, or a human's deft grasp: Each is made possible by the seamless interplay between soft and rigid tissues. Muscles, tendons, ligaments, and bones work together to provide ...
