June 7, 2022 —Recent efforts have sought to make low-boom supersonic aircraft, but noise issues due to sonic booms may become more pronounced in cities, where buildings form canyons that distort the booms. ...
Jan. 11, 2021 —A multi-institution collaboration has been studying turbulence's influence on galaxy formation. The team recently revealed the so-called 'sonic scale' of astrophysical turbulence -- ...
July 7, 2021 —By 2050, faster adoption of electric vehicles (EVs) and faster generation of renewable energy will result in 99% less fossil fuel consumed and 93% less CO2 emissions from passenger and freight ...
July 19, 2021 —Research has identified a new material that may lead to lightweight armor, protective coatings, blast shields and other impact-resistant ...
Nov. 30, 2022 —Extreme pressures come with high-speed flight. The resulting aerodynamic forces can bring significant risk to deforming the components of the vehicle in motion -- even to the point of aeroelastic ...
Nov. 10, 2020 —Forget glue, screws, heat or other traditional bonding methods. Engineers have now developed a 3D printing technique that creates cellular metallic materials by smashing together powder particles at ...
May 3, 2021 —The human world is, increasingly, an urban one -- and that means elevators. Two physicists saw this as an opportunity to explore the factors that determine elevator transport capabilities in a new ...
Jan. 25, 2023 —Allocating passenger aircraft emissions using airfares rather than travel class would give a more accurate idea of individual contributions, finds a new study. Including airfares in calculations ...
June 24, 2021 —Engineers find 'nanoarchitected' materials designed from precisely patterned nanoscale structures may be a promising route to lightweight armor, protective coatings, blast shields, and ...
Mar. 18, 2021 —Researchers have developed a world-first flow model that could cut public transport commuter times on busy roads by identifying and removing bottlenecks. Case studies have shown commuters saved close ...
