ETH Zurich researchers have developed multifunctional origami structures, which they then fabricated into 4-D printed objects. The design principle mimics the structure of an earwig's wing.
Researchers have now demonstrated the ability to create amorphous metal, or metallic glass, alloys using 3-D printing technology, opening the door to a variety of applications -- such as more efficient electric motors, better wear-resistant materials, higher strength materials, and lighter weight structures.
You really can extract clean drinking water right from the air, even in the driest of deserts, MIT researchers have found. They've demonstrated a real-world version of a water-harvesting system based on metal organic frameworks, or MOFs, that they first described last year.
In a study that holds promise for self-driving cars, MIT researchers have developed a system that can image and gauge the distance of objects shrouded by fog so thick that human vision can't penetrate it.
Technology developed at the University of Waterloo reliably and affordably increases the efficiency of internal combustion engines by more than 10 per cent.
Developers from Bosch and scientists at the Technical University of Munich (TUM) are using neutrons to analyze the filling of lithium ion batteries for hybrid cars with electrolytes. Their experiments show that electrodes are wetted twice as fast in a vacuum as under normal pressure.
Researchers have taken a key step toward helping wildlife coexist more safely with wind power generation by demonstrating the success of an impact detection system that uses vibration sensors mounted to turbine blades.
Lithium and cobalt are fundamental components of present lithium-ion batteries. Analysis by researchers at the Helmholtz Institute Ulm (HIU) of the Karlsruhe Institute of Technology (KIT) shows that the availability of both elements could become seriously critical. Cobalt-free battery technologies, including post-lithium technologies based on non-critical elements such as sodium, but also magnesium, zinc, calcium and aluminum, represent possibilities to avoid this criticality in the long term. These results are presented in Nature Reviews Materials.
A team of researchers led by Cleveland Clinic has published first-of-its-kind findings in Science Translational Medicine on a new method of restoring natural movement sensation in patients with prosthetic arms. Led by Paul Marasco, Ph.D., the research team has successfully engineered a sense of complex hand movement in patients with upper limb amputations. This breakthrough may enhance the ability to control their prostheses, independently manage activities of daily living and improve quality of life.
'It only took 30 minutes to find passwords for most of the devices and some of them were found only through a Google search of the brand,' says Omer Shwartz, a Ph.D. student and member of Dr. Oren's lab. 'Once hackers can access an IoT device, like a camera, they can create an entire network of these camera models controlled remotely.'
