Researchers at the Vienna University of Technology (TU Vienna) made a major breakthrough in speeding up the “two-photon lithography” 3D printing technique that enables their high-precision-3D-printer to print object in orders of magnitude faster compared to similar devices. Since dramatically increased speed of printing enables creation of much larger objects, the technique could find its… »

Almost 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 –… »
