Researchers have demonstrated a technique that allows them to track microscopic changes in metals or other materials in real time even when the materials are exposed to extreme heat and loads for an extended period of time -- a phenomenon known as 'creep.' The technique will expedite efforts to develop and characterize materials for use in extreme environments, such as nuclear reactors.
The general public knows the chemical compound of carbon dioxide as a greenhouse gas in the atmosphere and because of its global-warming effect. However, carbon dioxide can also be a useful raw material for chemical reactions. A working group at Karlsruhe Institute of Technology (KIT) has now reported on this unusual application in the ChemSusChem journal. They are using carbon dioxide as a raw material to produce graphene, a technological material which is currently the subject of intense study. (DOI: 10.1002/cssc.201901404)
Passenger and pedestrian confidence are key to future development of autonomous vehicles so researchers at WMG at the University of Warwick have conducted and reported an experiment to see which driving style engendered the highest levels of confidence among autonomous vehicles passengers - driving with full machine efficiency, or driving in a way that emulates average human driving. The surprising result was that neither was optimal but that a blend of both might be best.
Automatic landings have long been standard procedure for commercial aircraft. While major airports have the infrastructure necessary to ensure the safe navigation of the aircraft, this is usually not the case at smaller airports. Researchers at the Technical University of Munich (TUM) and TU Braunschweig have now demonstrated a completely automatic landing with vision assisted navigation that functions properly without the need for ground-based systems.
New study highlights the delay and deterioration in driving when older drivers have to 'take-back' control of their vehicle in difficult conditions.
An interdisciplinary research team at the Technical University of Munich (TUM) has built platinum nanoparticles for catalysis in fuel cells: The new size-optimized catalysts are twice as good as the best process commercially available today.
MIT researchers have assembled microrobots from a small set of standardized components, as a step toward self-replicating systems.
Micro mechanical elements are indispensable components of modern electrical devices but the actuation of them requires electrical current. It becomes harder to wire the element as further downscaling of device is pursued. As a way out of this issue, researchers demonstrated a new way to deliver a force to drive micro mechanics by spin current.
To meet internationally agreed-upon climate targets, the world's industrial nations will need to retire fossil fuel-burning energy infrastructure ahead of schedule, according to a new study in Nature from the University of California, Irvine and other institutions.
On a working wind farm, Stanford researchers have shown that angling turbines slightly away from the wind can boost energy produced overall and even out the otherwise variable supply.
