Copper fiber sheet commercialized by Good Eye

Good Eye (Kiryu City, Gunma Prefecture) will release GUD Sheet, a copper fiber sheet with antibacterial and antiviral effects, in June. The company commercialized four types of masks, including one priced at 4,980 yen (excluding consumption tax). The GUD sheet is a polymer fiber covered with copper foil and coated with a visible light responsive photocatalyst. In an experiment on bacteriophage, a virus that infects bacteria, it was confirmed that rubbing a finger covered with the virus on the sheet for 30 seconds reduced the number of the virus to less than 1/1000.Professor Hideyuki Itabashi of the Graduate School of Science and Engineering, Gunma University, who also serves as the company's chairman, said, "We hope to start experiments in July. The photo shows copper fiber sheets commercialized as masks and chiefs. (Photo taken on May 19, 2020, location unknown, credit: Nikkan Kogyo Shimbun / Kyodo News Images)

Professor Inoue of University of Tokyo, announce the identification of a new coronavirus drug candidate

Professor Junichiro Inoue and his colleagues at the University of Tokyo's Institute of Medical Science held a press conference on April 18 and announced that they had identified nafamostat. Nafamostat has been used for more than 30 years in Japan, and early clinical trials are expected to be conducted. The clinical research is expected to start by the beginning of April in cooperation with the National Center for Global Health and Medicine and others. When the new corona infects humans, proteins on the surface of the virus and proteins on the surface of human cells bind to each other, causing the outer membrane of the virus to fuse with the membrane of human cells. As a result, ribonucleic acid (RNA), which is the genetic information of the new corona, enters the human cell, and the virus multiplies.

Osaka University's compact and lightweight flexible thermoelectric conversion device

Associate Professor Toru Sugawara of the Institute of Scientific and Industrial Research, Osaka University, and Assistant Professor Kenzo Iwayano of the Graduate School of Engineering, Osaka University, and their colleagues have succeeded in reducing the size and weight of a flexible thermoelectric conversion device in which semiconductor chips are mountedon a flexible substrate. The new device converts the temperature difference between the two ends of the semiconductor into electrical information, and is equipped with a high density of about 200 ultra-small semiconductor chips per square centimeter, achieving high heat recovery efficiency and operational reliability. The flexible device, which was developed in 2018, has been improved. The new device uses semiconductor chips that are precisely aligned in size through ultra-fine processing that exceeds conventional methods.

Prof. Yotsuyanagi and Prof. Kawaoka of the University of Tokyo announcing the phase I clinical trial of iEvac-Z

Professor Hiroshi Yotsuyanagi, Professor Yoshihiro Kawaoka and their colleagues at the Institute of Medical Science, the University of Tokyo announced on April 5 that they will start Phase I clinical trials of the Ebola vaccine "iEvac-Z" at the hospital affiliated with the Institute this month. iEvac-Z is an inactivated vaccine made from mutant Ebola virus that lacks some of its genes. iEvac-Z is an inactivated vaccine produced from a mutant Ebola virus that lacks some of its genes, and is expected to be highly safe. The research team created a mutant virus that lacks the gene that makes VP30, a protein essential for the multiplication of the Ebola virus. Professor Yotsuyanagi said, "We can assume that there are side effects such as serious allergic symptoms that may occur in general, but nothing specific to iEvac-Z has been reported yet. We are planning to use it on people who are at high risk of infection" he explained. (= December 5, 2019, photo credit: Nikkan Kogyo Shimbun / Kyodo News Images)

Drainage ditch inspection robot for muddy water

Sanritsu Automation (Machida City, Tokyo), Aichi Institute of Technology, Tokyo Metropolitan Industrial Technology Research Institute, and others have developed an inspection robot that can operate in water and mud. Any distortions or deformations, such as pipes collapsing vertically, will be detected and reflected in the maintenance plan. The aircraft is 39 cm wide, 72 cm long, and 40 cm high, and the angle sensor on the aircraft can measure the inclination of water pipes in 1 degree increments. The angle of the concrete structure of the waterway and the angle of the joints will be measured to check the drainage performance. Drainage ditches of less than 60 cm in width were difficult for humans to enter, and it was necessary to check the amount of oxygen and whether gas was stagnant. After confirming its running and survey performance, the company will proceed with commercialization. (= November 14, 2019, photo credit: Nikkan Kogyo Shimbun / Kyodo News Images)

Graduate School of Engineering Science, Osaka University

The Graduate School of Engineering Science, Osaka University, and Toabo Corporation have developed a smart clothing (photo) that can be worn in extremely cold environments by combining natural fabric and electrodes for heart rate measurement. A research group led by the university succeeded in measuring biological data such as heart rate in an experiment conducted in the Arctic Circle over a period of about a month. It was confirmed that the garment is effective in measuring biological data and protecting against cold in extremely cold environments. This is the industry's first development of smart clothing made of natural materials. The measurement data will be used for the commercialization of smart clothing for mountain climbing and for research on the prevention of hypothermia.

Car developed jointly by Mitsuoka Motor, Isetan on sale

TOKYO, Japan - Mitsuoka Motor Co. unveils "Himiko Crazy Timer," a new model developed jointly with Isetan Mitsukoshi Holdings Ltd., at Isetan's flagship department store in Shinjuku, Tokyo, on Sept. 10, 2014. Only 20 cars will be produced and orders accepted at the store. (Kyodo)

Tora-fugu now can be raised in a tank of fresh water

OKAYAMA, Japan - The Japanese delicacy tora-fugu is a species of puffer fish that lives in sea water. Now, a research team at Okayama University of Science Professional Training College in Okayama Prefecture has succeeded breeding them in fresh water. The trick, the researchers there say, is to add a small amount of electrolytes into the water. The taste of fresh water-raised tora-fugu, the students involved in the project say, is ''really tasty.''

Researchers develop crystal material offering brighter red light

NAGOYA, Japan - A Japanese research group said April 2 it has developed a material from tin oxide micro crystals that can emit red light (R) at four times the brightness of current materials (L), and can be used to improve plasma TVs and fluorescent lights. The group is led by Masayuki Nogami, an engineering professor at the Nagoya Institute of Technology. Photo was provided by the institute. (Kyodo)

Experts hold int'l symposium on prevention of carp herpes

YOKOHAMA, Japan - Ronald Hedrick, a professor at California State University, delivers a keynote address at a symposium held in Yokohama on March 13 to discuss preventive measures on carp herpes, which hit carp farmers in Japan late in 2003. Hedrick said despite the common belief that the virus is not active in cold water temperatures, research showed that even at a water temperature of 13 C, the virus survived for two months. (Kyodo)
