Scientists from the University of Bristol, in collaboration with the Technical University of Denmark (DTU), have successfully developed chip-scale devices that are able to harness the applications of quantum physics by generating and manipulating single particles of light within programmable nanoscale circuits.  Physicists in China and Austria have shown for the first time they can teleport multi-dimensional states of photons.  A workshop on exploring extreme-field QED and the physics phenomena it creates will be held at SLAC in late summer.  University of Toronto Engineering researchers have combined two emerging technologies for next-generation solar power-and discovered that each one helps stabilize the other.  Photoresponsive flash memories made from organic field-effect transistors (OFETs) that can be quickly erased using just light might find use in a host of applications, including flexible imaging circuits, infra-red sensing memories and multibit-storage memory cells.  Recent research from Kumamoto University in Japan has revealed that polyoxometalates (POMs), typically used for catalysis, electrochemistry, and photochemistry, may also be used in a technique for analyzing quantum dot (QD) photoluminescence (PL) emission mechanisms.  Researchers have designed a new type of laser called a quantum dot ring laser that emits red, orange, and green light.  The world of nanosensors may be physically small, but the demand is large and growing, with little sign of slowing.  In a joint research project, scientists from the Max Born Institute for Nonlinear Optics and Short Pulse Spectroscopy (MBI), the Technische Universität Berlin (TU) and the University of Rostock have managed for the first time to image free nanoparticles in a laboratory experiment using a highintensity laser source.  For the first time, researchers have built a nanolaser that uses only a single molecular layer, placed on a thin silicon beam, which operates at room temperature.  A team of engineers at Caltech has discovered how to use computer-chip manufacturing technologies to create the kind of reflective materials that make safety vests, running shoes, and road signs appear shiny in the dark.
