  • EnergyNovel nanosized antenna arrays key to effective harvesting of solar energy

    For years, scientists have studied the potential benefits of a new branch of solar energy technology that relies on incredibly small nanosized antenna arrays that are theoretically capable of harvesting more than 70 percent of the sun’s electromagnetic radiation and simultaneously converting it into usable electric power. A novel fabrication technique could provide the breakthrough technology scientists have been looking for to improve today’s solar energy systems.

  • Invisibility cloaksNew invisibility cloak conceals objects from human view

    For the first time, scientists have devised an invisibility cloak material that hides objects from detection using light that is visible to humans; the new “carpet cloak” works by concealing an object under layers of silicon oxide and silicon nitride etched in a special pattern, and bending light waves away from the bump that the object makes, so that the cloak appears flat and smooth like a normal mirror

  • China syndromeChina establishes itself as a physics powerhouse

    Published journal articles in nanoscience, with at least one co-author based in China, have seen a 10-fold increase since the beginning of the millennium, rising to more than 10,500 in 2007; China has already overtaken the United Kingdom and Germany in the number of physics papers published and is beginning to nip at the heels of the United States; the verdict on the quality of many of these papers is still out

  • Reasons for optimism over US particle physics

    A panel of experts advising the U.S. Department of Energy says that recent cuts in funding for particle physics research may not do as much harm to U.S. basic research as scientists initially thought

  • On the water frontBacteria and nanofilters -- the future of clean water technology

    University of Nottingham researchers combine contaminant-eating bacteria with nanoscale filtration membranes to purify fouled water; additional side benefit: The waste products created by purifying water have a very high calorific value, and can be used as fuel

  • On the water frontCleaner water through nanotechnology

    As global warming causes more and more countries to have less and less fresh water for human consumption and irrigation, the purification and re-use of contaminated water becomes more urgent; Aussie researchers offer a nanotechnology-based method to purify water which is more effective and cheaper than conventional water purification methods
