19/02/2019Researchers at the University of Maryland have engineered a new fabric from synthetic yarn with a carbon nanotube coating that is activated by temperature and humidity, releasing heat in warm humid conditions and trapping heat when conditions are cool and dry.
18/02/2019While the polyester leisure suit was a 1970s mistake, polyester and other synthetic fibers like nylon are still around and are a major contributor to the microplastics load in the environment, according to a Penn State materials scientist, who suggests switching to biosynthetic fibers to solve this problem.
18/02/2019Researchers at Aalto University have developed new metasurfaces for the arbitrary manipulation of reflected waves, essentially breaking classical reflection law to engineer it at will.
15/02/2019Researchers at Duke University have discovered that a perfect absorber of electromagnetic waves they described in a 2017 paper can easily be tweaked into a sort of 'time-reversed laser' known as a coherent perfect absorber (CPA).
15/02/2019A research team from University of Science and Technology of China develops a simple and economical process to fabricate large-scale flexible smart windows.
14/02/2019Organic semiconductors are lightweight, flexible and easy to manufacture. But they often fail to meet expectations regarding efficiency and stability. Researchers at the Technical University of Munich (TUM) are now deploying data mining approaches to identify promising organic compounds for the electronics of the future.
14/02/2019A layer of red phosphorus in rechargeable lithium metal batteries can signal when damaging dendrites threaten to create a short circuit. The strategy, which does not require a third electrode, could help bring more powerful lithium metal batteries to market.
13/02/2019A novel ruthenium-based catalyst developed at UC Santa Cruz has shown markedly better performance than commercial platinum catalysts in alkaline water electrolysis for hydrogen production. The catalyst is a nanostructured composite material composed of carbon nanowires with ruthenium atoms bonded to nitrogen and carbon to form active sites within the carbon matrix.
13/02/2019Researchers from Georgia Institute of Technology, University of California San Diego and Massachusetts Institute of Technology have reported new findings about perovskite solar cells that could lead the way to devices that perform better.
12/02/2019Constant question: nanolaser or just simple LED? Physicists from MIPT have developed a method that will help you to find at what circumstances nanolasers qualify as true lasers bypassing technically challenging direct coherence measurements.
