    Transparent, Conductive Films promising for developing Flexible Screens

    June 7, 2018, Categories  Physics, Technology/Electronics, Chemistry/Nanotechnology

    The researchers used an approach called colloidal lithography to create a silver nanopattern that conducts electricity while letting light through the holes. The new transparent electrode films could be useful for solar cells as well as flexible displays and touch screens. Credit: Jes Linnet, University of Southern Denmark

    Silver-based electrode films could be used for flexible touch displays, televisions and solar cells. Researchers have demonstrated large-scale fabrication of a new type of transparent conductive electrode film based on nanopatterned silver. Smartphone touch screens and flat panel televisions use transparent electrodes to detect touch and to quickly switch the color of each pixel...

    How can quantum information be transferred from one atom to another? Quantum physics is on the brink of a technological breakthrough: new types of sensors, secure data transmission methods and maybe even computers could be made possible thanks to quantum technologies. However, the main obstacle here is finding the right way to couple and precisely control a sufficient number of quantum systems (for example, individual atoms).

    A team of researchers from TU Wien and Harvard University has found a new way to transfer the necessary quantum information. They propose using tiny mechanical vibrations...

    A Rutgers-led team of physicists has demonstrated a way to conduct electricity between transistors without energy loss, opening the door to low-power electronics and, potentially, quantum computing that would be far faster than today’s computers. Their findings, which involved using a special mix of materials with magnetic and insulator properties, are published online in Nature Physics.
     
    “This material, although it’s much diluted in terms of magnetic properties, can still behave like a magnet and conducts elec...

    XENON1T experimental data establishes most stringent Limit on Dark Matter

    May 31, 2018, Categories  Physics, Astronomy/Space

    Experimental results from the XENON1T dark matter detector limit the effective size of dark matter particles to 4.1X10-47 square centimeters--one-trillionth of one-trillionth of a centimeter squared--the most stringent limit yet determined for dark matter as established by the world's most sensitive detector.

    Analysis scours 276 days of data from world’s most sensitive detector. Experimental results from the XENON1T dark matter detector limit the effective size of dark matter particles to 4.1 x 10-47 square centimeters – one-trillionth of one-trillionth of a centimeter squared – the most stringent limit yet determined for dark matter as established by the world’s most sensitive detector.

    The results, presented Monday in a seminar in Italy at the Gran Sasso Undergr...
