In a recent study, materials scientists Guojin Liang and his coworkers at the Department of Materials Science and Engineering, City University of Hong Kong, have developed a self-healing, electroluminescent (EL) device that can repair or heal itself after damage.  A team of researchers based at The University of Manchester have found a low cost method for producing graphene printed electronics, which significantly speeds up and reduces the cost of conductive graphene inks.  Graphene-based computer components that can deal in terahertz “could be used, not in a normal Macintosh or PC, but perhaps in very advanced computers with high processing rates,” Ozaki says. This 2-D material could also be used to make extremely high-speed nanodevices, he adds.  Printed electronics use standard printing techniques to manufacture electronic devices on different substrates like glass, plastic films, and paper.  A tiny laser comprising an array of nanoscale semiconductor cylinders (see image) has been made by an all-A*STAR team.  A new instrument lets researchers use multiple laser beams and a microscope to trap and move cells and then analyze them in real-time with a sensitive analysis technique known as Raman spectroscopy.
