    Until quite recently, creating a hologram of a single photon was believed to be impossible due to fundamental laws of physics. However, scientists at the Faculty of Physics, University of Warsaw, have successfully applied concepts of classical holography to the world of quantum phenomena. A new measurement technique has enabled them to register the first ever hologram of a single light particle, thereby shedding new light on the foundations of quantum mechanics. “We performed a relatively simple experiment to measure and view something incredibly difficult to observe: the shape of wavefronts of a single photon,” says Dr. Chrapkiewicz.

    For years, materials have been made at the nanoscale level to take advantage of their mechanical, optical, and energy properties, but efforts to scale these materials to larger sizes have resulted in diminished performance and structural integrity. Now, researchers describe a new process to create lightweight, strong and super elastic 3D printed metallic nanostructured materials with unprecedented scalability, 7 orders of magnitude control of arbitrary 3D architectures.

    Strikingly, these multiscale metallic materials have displayed super elasticity because of their design...

    Tiny Transformers: Chemists create Microscopic and Malleable Building Blocks

    July 18, 2016, Categories  Physics, Technology/Electronics

    A team of NYU chemists has created malleable and microscopic self-assembling particles that can serve as the next generation of building blocks in the creation of synthetic materials. The research focused on engineering particles a micrometer in width -- about 1/200th the width of a strand of human hair (on which the particles [pink and blue] are placed in the above image).

    Scientists found a Molecule that will help to make organic electronic devices. A derivative of [3]-radialene, a molecule known to the science for nearly 30 years, can be used to create organic semiconductors. Dmitry Ivanov, Moscow State University, believes the achievement will greatly contribute to the development of organic electronics and, in particular, to fabrication of organic LEDs and new classes of organic solar cells.

    Organic or “plastic” electronics is a relatively young scientific field, which came to life about 15-20 years ago...
