» 5 Dec 2013 Successful Determination of Silicene Structure Using Reflection High-Energy Positron Diffracion (RHEPD)  The groups of Prof. Toshio Hyodo, Institute of Materials Structure Science, KEK; Dr. Atsuo Kawasuso, Principal Researcher, Advanced Science Research Center, Japan Atomic Energy Agency; and Associate Prof. Iwao Matsuda, The Institute for Solid State Physics, The University of Tokyo studied the structure of silicene, which consists of a single layer of silicon deposited on a single-crystal silver (Ag) surface, using reflection high-energy positron diffraction (RHEPD). This technique can accurately determine atomic positions on the top surface of a crystal. These groups experimentally confirmed for the first time that silicene has an buckling structure unlike planar graphene, which consists of a flat single layer of carbon atoms.
» 25 Oct 2013 Successful development of a 500-m-long laser-based fiducial line for high precision alignment of long-distance linear accelerators  A research group led by Tsuyoshi Suwada, an associate professor at the High Energy Accelerator Research Organization (KEK), and Souichi Telada, a head researcher at the National Institute of Advanced Industrial Science and Technology (AIST) of Japan, has succeeded for the first time in developing a laser-based alignment system that allows a high precision alignment of a linear accelerator along a 500-m-long fiducial line.
» 22 Jul 2013 Mechanism of insulation degradation in ceramic capacitors due to hydrogen impurities  A joint research group comprising researchers from the Advanced Science Research Center at the Japan Atomic Energy Agency, Institute of Materials Structure Science at KEK, and J-PARC Center has elucidated the mechanism of insulation degradation due to trace amounts of hydrogen impurities in barium titanate (BaTiO3), a representative ferroelectric material used in ceramic capacitors.
» 19 Jul 2013 New results from T2K conclusively show muon neutrinos transform to electron neutrinos  Today at the European Physical Society meeting in Stockholm, the international T2K collaboration announced definitive observation of muon neutrino to electron neutrino transformation.
» 21 Mar 2013 J-PARC won world record of neutron beam intensity!  The neutron beams were examined and analyzed in detail and the number of neutrons turned out to be 6.5 X 1013 per pulse. We proudly announce that J-PARC provide the strongest pulsed neutron beams in the world.
» 8 Feb 2013 A Cheaper Way to Get Energy from Hydrogen
- Inspired by Nature, Developed by Chemists
  Scientists at Kyushu University, Japan, have invented a new catalyst that can release electrons from hydrogen gas. The catalyst is a molecule that relies on cheap iron and nickel and works at room temperature and atmospheric pressure. This development is a crucial step in replacing fossil fuels with renewable energy sources.
» 30 Jan 2013 Suppressing Pressure Waves with Micro-Bubbles
- The technology that helped realize the world's most intense source of pulsed neutrons -
  One major technological barrier to the realization of higher power spallation neutron sources is the damage caused by high-pressure waves that are generated within the mercury vessel due to rapid thermal expansion of mercury. This damage - known as pitting - scales with proton beam power and can seriously limit the lifetime and reliability of the target assembly. Accordingly, R&D work aimed at suppressing, or mitigating the effect of, these pressure waves is a major research theme at facilities that currently use liquid mercury targets or propose to do so in future designs.
» 10 Jan 2013 Development of a purely organic single-component conductor in a metallic state
The team led by Professor Hatsumi Mori at the Institute for Solid State Physics, the University of Tokyo, developed a new type of purely organic single-component conductor.
