In a new paper published in Light Science & Application, a team of European scientists and engineers from ICFO and IRIS in Spain, Ipsumio B.V. in the Netherlands, the Technical University of Denmark, the Technische Universität Dresden in Germany and the University of Leeds in the UK, has developed a new micro-particle size analyser by combining consumer electronics products and artificial intelligence. [50] Researchers in Australia have found a way to manipulate laser light at a fraction of the cost of current technology. [49] The proposed design breaks the current bandwidth limit in the transmission-type coding metasurfaces, indicating wide application potentials in radar and wireless communication systems. [48] In a similar vein, scientists are working to create twisting helical electromagnetic waves whose curvature allows more accurate imaging of the magnetic properties of different materials at the atomic level and could possibly lead to the development of future devices. [47] 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. [46] 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. [45] 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. [44] Printed electronics use standard printing techniques to manufacture electronic devices on different substrates like glass, plastic films, and paper. [43] A tiny laser comprising an array of nanoscale semiconductor cylinders (see image) has been made by an all-A*STAR team. [42]
