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… Read more

New membrane may solve fresh water shortages

New membrane may solve fresh water shortages

  Researchers at Hiroshima University have developed a technology that improves the removal of salt from seawater, a breakthrough that may alleviate the increasing demand for fresh water in some countries. “A global shortage of fresh water is a long-term challenge that mankind faces in this century,” said the director of the ROBUST membrane project,… 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… Read more

Ultra-thin, all-inorganic molecular nanowires successfully compounded

Ultra-thin, all-inorganic molecular nanowires successfully compounded

  Nanowires are wired-shaped materials with diameters that are tens of nanometers or less. There are many types of nanowires, including semiconducting composite nanowires, metal oxide composite nanowires, and organic polymer nanowires, and they are typically used in functional materials and devices used as sensors, transistors, semiconductors, photonics devices, and solar cells. Molecular wires composed… Read more
