A proposed hybrid-electric plane could "eliminate aviation's air pollution problem," say MIT engineers. Their design could reduce global nitrogen oxide (NOx) emissions by 95 percent, they report in a study.
Cities are responsible for 60-70% of energy-related CO2 emissions. As the world is increasingly urbanized, it is crucial to identify cost-effective pathways to decarbonize. Here, we propose a "SolarEV City" concept, in which integrated systems of cities' roof-top PVs with EVs as batteries can supply affordable and dispatchable CO2-free electricity for citie's dwerllers, which can reduce CO2 emission by 54-95% with 26-41% of potential cost savings by 2030.
ORNL story tips: Nanoscale commuting, easy driver and defect detection.
Assembling tiny chips into unique programmable surfaces, Princeton researchers have created a key component toward unlocking a communications band that promises to dramatically increase the amount data wireless systems can transmit.
Fuel cells based on methanol oxidation have a huge potential in the motor and technical industries. To increase their energy performance, scientists suggest using electrodes made of thin palladium-based metallic glass films. A group of researchers from Far Eastern Federal University (FEFU), Austria, Turkey, Switzerland, and the UK has developed a new metallic glass for this application. The results were reported in the Nanoscale journal.
A new material developed by a team led by Berkeley Lab will help to make hydrogen a viable energy source for a wide range of applications.
In the quest for advanced vehicles with higher energy efficiency and ultra-low emissions, Oak Ridge National Laboratory researchers are accelerating a research engine that gives scientists and engineers an unprecedented view inside the atomic-level workings of combustion engines in real time.
Researchers believe a new hinge is the key to get load-bearing, large, Army quadrotors to climb a few dozen feet in seconds
Scientists have improved a promising battery technology, creating a single-crystal, nickel-rich cathode that is hardier and more efficient than before. It's one step toward improved lithium-ion batteries that are common in electric vehicles today. Increasing nickel content in the cathode is on the drawing board of lithium-ion battery makers largely because of its relatively low cost, wide availability and low toxicity compared to other key battery materials, such as cobalt.
Additive manufacturing (AM) machinery has advanced over time, however, the necessary software for new machines often lags behind. To help mitigate this issue, Penn State researchers designed an automated process planning software to save money, time and design resources.
