Professor Junsuk Rho of the departments of mechanical engineering and chemical engineering and doctoral student in mechanical engineering Gwanho Yoon at POSTECH with the research team at Korea University have jointly developed moldable nanomaterials and a printing technology using metamaterials, allowing the commercialization of inexpensive and thin VR and AR devices.
Connected and automated vehicles use technology such as sensors, cameras and advanced control algorithms to adjust their operation to changing conditions with little or no input from drivers. A research group at the University of Delaware optimized vehicle dynamics and powertrain operation using connectivity and automation, while developing and testing a control framework that reduced travel time and energy use in a connected and automated vehicle.
Researchers from MIT and Brigham and Women's Hospital have developed a new way to share ventilators between patients, which they believe could be used as a last resort to treat Covid-19 patients in acute respiratory distress.
Using exhaust gas measurements taken from the roadside, a team from the University of York and Empa was able to prove the "Dieselgate" scandal has led to positive results. The forced retrofitting of thousands of VW diesel engines saves the environment throughout Europe considerable amounts of Nitrogen oxide (NOx).
Solid state batteries are of great interest to the electric vehicle industry. Scientists at Chalmers University of Technology, Sweden, and Xi'an Jiaotong University, China now present a new way of bringing this promising concept closer to application. An interlayer, made of a spreadable, 'butter-like' material helps improve the current density tenfold, while also increasing performance and safety.
A new way of creating carbon fibers -- which are typically expensive to make -- could one day lead to using these lightweight, high-strength materials to improve safety and reduce the cost of producing cars, according to a team of researchers. Using a mix of computer simulations and laboratory experiments, the team found that adding small amounts of the 2D graphene to the production process both reduces the production cost and strengthens the fibers.
Imagine a self-repairing rubber, or super-adhesive made entirely from waste materials. It sounds like science fiction, but researchers have discovered a new kind of rubber and catalyst that together can be used with low energy consumption to make flexible, repairable, sustainable objects.
Robots can be made from soft materials, but the flexibility of such robots is limited by the inclusion of rigid sensors necessary for their control. Researchers created embedded sensors, to replace rigid sensors, that offer the same functionality but afford the robot greater flexibility. Soft robots can be more adaptable and resilient than more traditional rigid designs. The team used cutting-edge machine learning techniques to create their design.
Miniature devices, notably those that bulge out from 2D surfaces like pop-up greeting cards, have seamlessly found their way into pressure-sensing and energy-harvesting technologies because of their ability to be frequently stretched, compressed or twisted. Despite their force-bearing abilities, it is still unclear if repeated physical stress can damage the working of these miniature devices, particularly if there is already a defect in their construction.
Research from the LAMP Lab at the University of Pittsburgh Swanson School of Engineering has created a textile coating that can not only repel liquids like blood and saliva but can also prevent viruses from adhering to the surface. The work was recently published in the journal ACS Applied Materials and Interfaces.
