Equipment used in experiments at Kochi University of Technology

Professor Tetsuya Yamamoto and his colleagues at Kochi University of Technology and the Technical Research Institute of Sumitomo Heavy Industries, Ltd. have developed a technology that can change the characteristics and add functions to oxide semiconductors in the same equipment after stabilizing them using negative oxygen ions in the deposition process. The process is a highly efficient way to create negative ions of oxygen in a plasma thin film deposition system and attract them to the substrate side by applying a voltage. Prof. Yamamoto is also scheduled to deliver a keynote speech on this theme at an international conference on film formation technology hosted by a German film formation equipment manufacturer in March 2008.

    Technology to etch Kai semiconductor with fluoroplastic instead of CFC gas

    Technology to etch Kai semiconductor with fluoroplastic instead of CFC gas

    The established technology will be used for dry etching, thin film formation and cleaning of silicon. Easy-to-handle gases such as argon and nitrogen are irradiated onto solid fluoropolymers to generate fluorine-containing gas. The gas is then used for plasma treatment. Using a proto device with electrodes developed for special equipment, the company irradiated nitrogen gas and etched a glass substrate, and was able to etch 40 nanometers in one minute. The company plans to achieve an etching speed of 200 nanometers for commercialization. Plasma is an unstable state in which electrons have been removed from molecules, and it modifies the surface of materials, improving adhesion and cleaning effects.

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

      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

        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)

            Perovskite solar cell device developed by Yamagata University

            Professor Kenshi Sano and his team at Yamagata University have developed a perovskite solar cell with a structure called "reverse type" fabricated by a low-temperature formation process of 150 degrees C or lower. So far, the conversion efficiency of the low-temperature formation and inverse-type structure has been 17-19%, but using Yamagata University's organic EL manufacturing technology, they have confirmed a conversion efficiency of over 20%. Conventionally, solar cells have been fabricated using a high-temperature formation method called the "forward type," in which an electron transport layer (titania) is baked on top of a special transparent conductive film using a high-temperature process (approximately 500 degrees C). The research team at Yamagata University has been working on the inverse type device structure, which can reduce the process temperature.
