researchers from the National Institute of Standards and Technology (NIST) have been developing a laser power sensor that could be built into manufacturing devices for real-time measurements in many manufacturing processes, from welding car parts to crafting engine components with 3D printers.
A research group led by Assistant Professor Yosuke Ishii at Toyohashi University of Technology has unraveled the phenomenon of a new 'third ultrasonic wave' being generated when two ultrasonic waves intersect within a plate. This wave exhibits varying intensity in response to material damage and can therefore be used for nondestructively testing thin plate structures. This new technology surpasses conventional technology, enabling precise and nondestructive detection of fatigue and early damage.
Gilding is the process of coating intricate artifacts with precious metals. Ancient Egyptians and Chinese coated their sculptures with thin metal films using gilding -- and these golden sculptures have resisted corrosion, wear, and environmental degradation for thousands of years. In a new study, University of Illinois researcher Sameh Tawfick, inspired by this ancient process, has added a single layer of carbon atoms, known as graphene, on top of metal leaves -- doubling the protective quality of gilding against wear and tear.
Researchers at Carnegie Mellon University have devised a way to automatically transform the content of one video into the style of another, making it possible to transfer the facial expressions of comedian John Oliver to those of a cartoon character, or to make a daffodil bloom in much the same way a hibiscus would.
A new U of T Engineering study reveals large diesel trucks to be the greatest contributors to harmful black carbon emissions close to major roadways, indicating that vehicle types matter more than traffic volume for near-road air pollution.
Scientists developed a model for predicting hand movement trajectories. The predictions relies on lineal model, not neural networks. It has the same accuracy of predictions, requires less memory and fewer computations, so the sensor keeps patient's brain cool. This technology could drive exoskeletons that would allow patients with impaired mobility to regain movement.
Tel Aviv University researchers have invented a 'Robat,' a fully autonomous terrestrial robot with bat-like qualities that uses echolocation to move through novel environments while mapping them based only on sound.
Southwest Research Institute engineers are developing a cooled, radial gas turbine for a small generator that provides thousands of hours of electricity to an unmanned aerial vehicle (UAV), a significant improvement to current UAV turbines that only operate a few hundred hours before wearing out.
Research published in the journal Materials Today demonstrates a new approach to 3D printing to fuse metallic filaments made from metallic glass into metallic objects.
MIT researchers led by Kripa Varanasi found a way to prevent icing of powerlines, airplanes, wind turbines, and other surfaces with a special coating and the power of sunlight -- no heating or harsh chemicals needed.
