SciTech News:

Green Science Alliance announced that they made graphite-like Carbon Nitride C3N4 available in mass-production. Unlike TiO2 which utilizes only UV region of light, EM radiation, Carbon Nitride utilizes visible region of light. Thereby, it is expected to be used in production of hydrogen gas, and in efficient artificial photosysnthesis, etc.

Researchers at Kyoto Univ. and Mie Univ. found that a nanometer-thin film of metalic Pt (Platinum) formed on YIG (Yttrium-Iron-Garnet) substrate showed semi-conductor characteristics reducing its resistance by half. Furthermore, it showed even the modulation of spin flow to current by as much as 280%. They say that this result might be applied to a new kind of memory devices in spintronics.

It was published in Scienctific Reports that a vast amount of mud containing rare-earth elements, such as 39Y (Ytrrium), 65Tb (Terbium), 66Dy (Dysprosium), was found at Minami-Torishima Island in the south of Japan. The research was conducted by the University of Tokyo, Waseda Univ., and others.
Note: rare-earth elements are defined in IUPAC: 21Sc, 39Y, and 14 Lanthanides: 57La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, plus 71Lu.

National Institute of Advanced Industrial Science and Technology (AIST) announced that they developed one-electron modulation and generated a pulse of square wave consisting of any number of electrons. It will make it possible to measure femto or atto Ampere on a nano-scale structure and to contribute to the development of future spintronics.

University of Kyushu, Japan, announced that the research team has developed the molecule for generating hydrogen utilizing near infrared region of light spectra. As a result of using the longer wave length, the efficacy of utilizing light energy is shown to increase about two-fold.

Showa Shell Sekiyu announced that they developed Artificial Photosysnthesis to produce CH4 at the rate of 0.61% and C2H4 0.1%, respectively. They say that they further make efforts in increasing the rate of conversion in order to contribute to sustainable society in the future.

Hitachi announced that they developed a 'lens-less' camera, which utilizes special films to gather information on light. It can adjust a focus to make the image clearer even after the image has been recorded.

NICT (National Institute of Information and Communications Technology) announced that they developed a projection-type see-through holographic 3D display, which currently shows only in green color. Holographic 3D image is first created by use of 3D Holographic printer on a film, then the reconstructed holographic 3D image was projected onto a target observation area.

A research group of JAEA, Tohoku Univ., and Material Institute announced that they developed transparent material that shows ferromagnetism.

According to a research group at the Department of Polymer Science and Engineering of KYOTO INSTITUTE OF TECHNOLOGY, it was discovered that a bacillus resolves PET (Polyethylene Telephtalate) into CO2 and H2 as the final form.

According to the research group of Tokyo Univ. and Tokyo Institute of Technology, they found that the improvement in piezoelectric crystal is made through the rotation of the polarization axis. This may be used to create a new piezoelectric material without the use of Pb.

It was announced that there seems to be an indication of CP violation in nutrino oscillation through the high-energy experiment. It is known that although CPT is invariant, parity is violated in the weak interaction - beta-decay, and CP (Charge-Parity) is violated in K meson decay. If CP is found to be violated in nutrino oscillation, imbalanced existence of matter - antimatter may be explained.

According to the international research team, it was announced that there seems to be few younger stars found around the center of our galaxy. They found 29 relatively young Cepheid variable stars, by which the distance is measured, but no such younger stars found upto 8000 ly (light year) from the center.

Honda Motor and Daido Steel Co., Ltd. announced that they developed the world first neodymium magnet that contains no heavy rare earth (e.g., dysprosium, terbium, etc.). The resultant high performance magnet can be used in Hybrid and Electric Vehicles.
