Research Bits: Nov. 26


Hydrogel NAND gate Researchers from McMaster University and the University of Pittsburgh created a functionally complete NAND gate in a soft material using only beams of visible light. The NAND logic operation was completed by shining three self-trapped light beams into a photoresponsive merocyanine-functionalized hydrogel that is capable of performing compute tasks in the material itself w... » read more
