3d-photonic-crystal-ledPrevious attempts at making 3D photonic crystals have resulted in devices that are only optically active (they can’t turn electricity to light or vice versa). A group of researchers, led by researchers from the University of Illinois, have managed to develop the first optoelectronically active 3D photonic crystal. The development could enable new advancements for… »

ua-blackledge-sahni-dhinojawala-spider-silk-glueA team of researchers from the University of Akron (UA) has observed two species of spiders in order to develop stimuli-resistant and stimuli-sensitive materials. The research shows that the sticky glue that coats the silk threads orb-weaving spiders spin has a different structure, property makeup and response to humidity than glues produced by their evolutionary… »

sotzing-instant-color-change-lensesA team of researchers from University of Connecticut (UConn) perfected a method for creating quick-changing, variable colors in films and displays. They managed to make them less expensive and less wasteful to manufacture compared to any previous method. The technology could be used for displays, solar cells, OLEDs, transistors, vanity glasses, or glasses used by… »

mit-paper-printed-solar-cells-1Almost as cheaply and easily as printing a photo on your inkjet, an inexpensive, simple solar cell can be created by special “inks” deposited on the paper. The researchers from MIT came with a process essentially the same as the one used to make the silvery lining on packages you see in everyday groceries –… »
