An international research team led by scientists from City University of Hong Kong (CityU) has recently discovered that high-entropy alloys (HEAs) exhibit exceptional mechanical properties at ultra-low temperatures due to the coexistence of multiple deformation mechanisms. Their discovery may hold the key to design new structural materials for applications at low temperatures.
Scientists at The University of Tokyo developed a new computer simulation model that includes microbubble nucleation to explain the flow slippage of fluids inside pipes. This work may help improve the flow rate of viscous fluids in commercial applications, as in the energy industry.
Researchers find that a motorized device that attaches around the ankle and foot can drastically reduce the energy cost of running.
Song Zhang, a professor of mechanical engineering in Purdue University's College of Engineering, led a team to create technologies to help compress 3D camera files and automate focus and exposure settings.
NIST researchers spent months meticulously recreating the long concrete floors supported by steel beams commonly found in high-rise office buildings, only to set the structures ablaze. These experiments indicate that structures built to code are not always equipped to survive the forces induced by extreme shifts in temperature, but the data gained here could help researchers develop and validate new design tools and building codes that bolster fire safety.
A simulation system invented at MIT to train driverless cars creates a photorealistic world with infinite steering possibilities, helping the cars learn to navigate a host of worse-case scenarios before cruising down real streets.
A study conducted by the Politecnico di Torino (Italy), in collaboration with the National Metrological Research Institute (INRiM) and recently published on Science Advances, proposes a new technology for space cooling. No electricity is needed, but rather salty water possibly produced exploiting solar radiation
KAIST researchers have developed a novel wearable strain sensor based on the modulation of optical transmittance of a carbon nanotube (CNT)-embedded elastomer. The sensor is capable of sensitive, stable, and continuous measurement of physical signals. This technology, featured in the March 4th issue of ACS Applied Materials & Interfaces as a front cover article, shows great potential for the detection of subtle human motions and the real-time monitoring of body postures for healthcare applications.
Fears that electric cars could actually increase carbon emissions are unfounded in almost all parts of the world, new research shows.
A research group coordinated by physicists of the University of Trento was able to probe internal stress in colloidal glasses, a crucial step to control the mechanical properties of glasses. Their work opens the way to new types of glass for new applications. The study was published in the US journal Science Advances.
