Latest developments on the science of chiral materials discussed at ChiMag2016 Symposium

The ChiMag 2016 Symposium is to be held from Sunday, Feb. 21 to Wednesday, Feb. 24 at Oriental Hotel Hiroshima in Hiroshima, Japan. The purpose of the symposium is to offer a good opportunity for researchers worldwide pursuing the nature of chiral magnets to discuss and exchange ideas. The main topics for the symposium are as follows: Nonlinear and topological spin textures in chiral magnets Probing spin chirality and crystallographic chirality by electron, neutron, X-ray, muon, and ultrasound beams Dzyaloshinskii-Moriya interaction in crystals with broken chiral symmetry Systematic synthesis of chiral magnetic crystals, including molecular-based, transition-metal, and rare-earth-based crystals Physics of helical and chiral superconductivity The online registration form is… Read more

A clue to generate electric current without energy consumption at room temperature

A clue to generate electric current without energy consumption at room temperature

  A group of researchers in Japan and China identified the requirements for the development of new types of extremely low power consumption electric devices by studying Cr-doped (Sb, Bi)2Te3 thin films. This study has been reported in┬áNature Communications. At extremely low temperatures, an electric current flows around the edge of the film without energy loss, and under no external magnetic field. This attractive phenomenon is due to the material’s ferromagnetic properties; however, so far, it has been unclear how the material gains this property. For the first time, researchers have revealed the mechanism by which this occurs. “Hopefully, this achievement will lead to the creation of novel materials that… Read more

Draw out of the predicted interatomic force

Draw out of the predicted interatomic force

  Grant-in-Aid for Scientific Research, the Ministry of Education, Culture, Sports, Science and Technology, Japan. Liquid Bi shows a peculiar dispersion of the acoustic mode, which is related to the Peierls distortion in the crystalline state. These results will provide valuable inspiration to researchers developing new materials in the nanotechnology field. Studies of the atomic dynamics in liquid Bi have been revisited more recently. The previous inelastic neutron scattering (INS) results for liquid Bi showed inconsistency for the inelastic excitation of the acoustic mode. These results were also different from the ab initio molecular dynamics (AIMD) prediction that indicated that the peculiar atomic dynamics arose from an anisotropic interatomic force… Read more

Protein machines make fluctuating flows unconsciously

Protein machines make fluctuating flows unconsciously

An international research group has demonstrated that protein machines, regardless of their specific functions, can collectively induce fluctuating hydrodynamic flows and substantially enhance the diffusive motions of particles in the cell. Biological cells contain large numbers of active proteins that repeatedly change their conformations. These protein machines have a variety of specific functions, acting as motors, ion pumps, or enzymes, and they need a supply of ATP or other substrates to maintain their cyclic operation. Professor Alexander S. Mikhailov (Department of Physical Chemistry, Fritz Haber Institute of the Max Planck Society, and Research Center for the Mathematics on Chromatin Live Dynamics [RcMcD] at Hiroshima University) and Professor Raymond Kapral (Department… Read more
