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 ...
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 ...
Apr. 20, 2021 To search for answers about how blood droplets from a gunshot wound can reverse direction while in flight, researchers explored the influence of propellant gases on blood backspatter. They report ...
