  • Controlling ice formation ۱۳۹۶/۱/۴

    (Phys.org)—Researchers have demonstrated that ice crystals will grow along straight lines in a controlled way on microgrooved surfaces. Compared to the random formation of ice crystals on smooth surfaces, the ice on the microgrooved surfaces forms more slowly and melts more quickly, which could lead to improved anti-icing and deicing methods. Ice formation is currently a major problem in a wide variety of areas, including solar panels, refrigeration systems, power transmission systems, and aircraft, and the new surface may help reduce ice build-up in these systems.

  • Multi-parameter microscopy aids design of improved optoelectronic devices ۱۳۹۶/۱/۴

    The National Physical Laboratory (NPL) has developed a novel measurement method, providing simultaneous topographical, electrical, chemical and optical microscopy (STEOM) at the nanoscale for the first time. The new method can be used to optimise the performance of optoelectronic devices such as organic solar cells, sensors and transistors.

  • The world's first international race for molecular cars, the Nanocar Race ۱۳۹۶/۱/۴

    Nanocars will compete for the first time ever during an international molecule-car race on April 28-29, 2017 in Toulouse (south-western France). The vehicles, which consist of a few hundred atoms, will be powered by minute electrical pulses during the 36 hours of the race, in which they must navigate a racecourse made of gold atoms, and measuring a maximum of a 100 nanometers in length. They will square off beneath the four tips of a unique microscope located at the CNRS's Centre d'élaboration de matériaux et d'études structurales (CEMES) in Toulouse. The race, which was organized by the CNRS, is first and foremost a scientific and technological challenge, and will be broadcast live on the YouTube Nanocar Race channel. Beyond the competition, the overarching objective is to advance research in the observation and control of molecule-machines.

  • Artificial photosynthesis steps into the light ۱۳۹۶/۱/۳

    Rice University scientists have created an efficient, simple-to-manufacture oxygen-evolution catalyst that pairs well with semiconductors for solar water splitting, the conversion of solar energy to chemical energy in the form of hydrogen and oxygen.

  • Insights pave way for solar cells and photodetectors based on tunable nanoparticles ۱۳۹۶/۱/۲

    Solar cells and photodetectors could soon be made from new types of materials based on semiconductor quantum dots, thanks to new insights based on ultrafast measurements capturing real-time photoconversion processes.

  • Biophysicists construct complex hybrid structures using DNA and proteins ۱۳۹۶/۱/۳

    Florian Praetorius and Prof. Hendrik Dietz of the Technical University of Munich (TUM) have developed a new method that can be used to construct custom hybrid structures using DNA and proteins. The method opens new opportunities for fundamental research in cell biology and for applications in biotechnology and medicine.
