- Professor Park Moon-soo and Park Sung-soo of the Mechanical Engineering, Development of Ozone Gas Technology for Mask
- Professor Park Moon-soo and Professor Park Sung-soo of the Mechanical Engineering Department, Mask Surface Coronavirus Development of Immediate Sterilization Ozone Gas Technology - Instant sterilization of coronavirus in 1 minute without compromising mask performance - Expected immediate use in countries with insufficient masks and medical sites requiring frequent replacement A research team led by Professor Park Moon-soo and Professor Park Sung-soo of the Department of Mechanical Engineering (Professor Lee Jin-yeop and Bong Chul-woo) announced that they have developed a technology that can apply the virus to a medical site that can process high concentrations of ozone gas produced by plasma generators in masks contaminated with coronavirus in one minute without compromising the performance of the mask at all. The researchers recognized that many countries suffered from a lack of supply of N95 (Korea KF94) masks equipped with electrostatic filters after the Corona 19 outbreak, and that the long-term use of contaminated masks has also increased the infection of medical staff. The researchers successfully suppressed 100 percent of the infection by exposing the surface of the mask contaminated with coronavirus for one minute at the level of 120 ppm of ozone gas, a disinfectant. It is expected to easily prevent mask contamination by other viruses and germs at medical sites as it can quickly kill not only coronavirus but also flu viruses and germs. The research team conducted heavy-duty tests on KF94 masks (five times per minute, exposure to 120 ppm ozone gas) and was verified by two national certification agencies for mask performance that maintains 98% of dust collection efficiency, which is the main performance of masks. It was also confirmed that the electrostatic filter structure of the mask was not damaged at all using the scanning electron microscopy. This means that masks can be recycled at least five times. Ozone generators on the market are designed to sterilize space in the form of air purifiers. However, low-concentration ozone gases do not make it effective against high-concentration viruses or bacterial sterilization. On the other hand, the team's treatment method uses a low-temperature upper-pressure plasma to generate 120 ppm of high-concentration ozone gas in the space where the mask is located to conduct sterilization. Since ozone is generated for a short time of one minute, the absolute amount is insignificant, either by opening windows after mask treatment or by using plasma generators in air circulationable hoods to prevent ozone-induced harmfulness problems. In addition, this technology is an on-site technology that can be easily applied to mask sterilization by domestic companies that produce plasma generators, and it is expected that it will be able to pioneer the market for overseas exports through the process of optimizing ozone gas exposure to masks. This study was conducted with the support of the Ministry of Science and ICT's Global Frontier Project (Director Shin Yong-beom, Director of Bio-Nano Healthguard Research Group) and BICS (Sunggyun Institute of Bio-Convergence Science and Technology) and KS (Gangbuk Samsung Hospital) Future Convergence Program. The results of this study were pre-published on the Internet site MedRxiv, which distributes undisclosed manuscripts on health science for the rapid dissemination of technology, and the paper is currently under review for formal publication. ※ Name of paper: Fast and easy disconnection of coronavirus-contaminated face masks using ozone gas supplied by a dielectric barrier desparage plasma generator. https://medrxiv.org/cgi/content/short/2020.04.26.20080317v1 Source of the thesis: https://medrxiv.org/cgi/content/short/2020.04.26.20080317v1.

- Lee Ki-ra, a co-research team of professors of chemical engineering, has developed sunscreen materials
- Lee Ki-ra, a co-research team of professors of chemical engineering, has developed sunscreen materials without white casts. A joint research team led by Professor Igira Iggyra of the Department of Chemical Engineering and Polymer Engineering announced on the 24th that it has developed a "porous micro-weapon material platform technology" that effectively reflects ultraviolet rays without white casts that make the face white when applied with sunscreen. The research was conducted as a joint project between Dr. Lee Yeon of Amorepacific Institute of Technology and Professor Igira Lee of Sungkyunkwan University's Department of Chemical Engineering. The joint research team has uniformly synthesized and assembled "silica spherical particles" in fine size and empty in the middle, and found that the film made of the particles strongly reflects ultraviolet light, but appears transparent in the visible light area. Using the new technology, the team explained, it can overcome the disadvantages of whitening the face or lumping the texture when applying sunscreen. "It is meaningful in that we have secured platform technology to develop materials for UV protection," said Amorepacific's Institute of Technology. "We will verify the possibility of utilization through skin clinical tests." The study was published in the online edition of the March issue of Particle & Particle Systems Characterization, an international academic journal in the field of materials, and was also selected as the cover of the April issue. https://news.joins.com/article/23762293

- Our University to Expand Online Lecture Servers... pre-emptive response brilliant university
- While major universities have extended the operation period of online lectures by one to two weeks, college students are increasingly interested in some schools, including Sungkyunkwan University, KAIST and Unist, which announced the operation of online lectures until the Corona 19 crisis stabilizes. If concerns over the coronal 19 group infection are not resolved, online classes at each university will have to be prolonged, which is why these school systems are believed to have presented some kind of guidelines. Sungkyunkwan University is operating online lectures stably more than other universities because it was preparing a step ahead. Previously, Sungkyunkwan University decided to introduce 'challenge semester' and planned to open its first semester of this year in February, reduce the number of weeks of classes from 16 weeks to 15 weeks, and increase its summer vacation to three months. Also included in the plan is the provision of all lectures online for the first and second weeks after the opening of the classes, increasing students' choice of classes. In preparation for this, the government had prepared infrastructure such as expanding servers and lines, considering that all students were simultaneously accessing online lectures depending on class time. It was only after such measures were taken that concerns over the Corona 19 infection spread. Sungkyunkwan University recently announced the period of operation of online lectures as 'Until Corona 19 situation is resolved' and announced additional supplementary measures to students and professors. Sungkyunkwan University proposed a plan to give undergraduate students three more credits each, and to increase the number of classes by up to 20 percent. It is also considering expanding the ratio of A+ to B grades from 65 percent of the existing number of students to 80 percent, considering when the academic schedule is centered on online lectures even after the midterm exam. An official from Sungkyunkwan University said on the 26th, "In order to improve the quality of online lectures, we will recruit 200 undergraduate students as 'technical assistants' to support professors who have difficulty in producing lectures. We are planning to provide scholarships worth 1.5 million won each to students participating here." Technical assistant students check in advance whether the program is working properly and if there is no problem with the server before the professor starts an online lecture. According to the school, the plan is aimed at helping professors focus only on producing lectures. In addition, Sungkyunkwan University frequently checks the current status of 4,000 lectures in schools according to the ministry's previous guidelines that they should be composed of "at least 25 minutes per credit" when producing online. It was found that 90 percent of the lectures in the second week of the semester and 91 percent in the third week met the criteria. However, some students at Sungkyunkwan University complain about the school's plan to run online lectures. "The tuition fee for a semester is over 12 million won, and networking in the school is an important course, and my colleagues are furious at the unilateral notification that I should only give online lectures throughout the semester," said a graduate student A. "There are talks about taking a semester off by taking a collective leave of absence." [Reporter Moon Kwang-min] [c Maeil Economy & mk.co.kr, Prohibit unauthorized transmission and redistribution]

- Park Jae-hyung, a professor of Chemical Engineering, increases the effectiveness of cancer treatment with nano bubbles
-
Park Jae-hyung, a professor in the Department of Chemical Engineering, increases the effectiveness of cancer treatment with cancer-causing nano bubbles. The Korea Research Foundation announced on September 9 that a research team led by Professor Park Jae-hyung of Sungkyunkwan University has developed a technology that can cause rupture of cancer cell membranes using nano bubbles that radiate ultrasonic waves. The "necroptosis" reaction, in which cancer cells destroy cell membranes and kill themselves, does not need to involve decomposing enzymes, which can reduce damage to immunogenic substances to a minimum. However, there is a limit to the development of treatments for most cancer cells due to low levels of protein that causes necrotosis. The research team succeeded in inducing similar necrotosis reactions by using physical stimuli, not proteins. The principle is to design a polymer that explodes cancer cells using bubbles and then warm up the ultrasound, and the liquid inside the polymer turns into a gas and causes the volume to expand and destroy cell membranes. The team observed that the structure of cancer cells collapses by nano bubbles once ultrasonic waves are warmed through a focal microscope. In particular, it has been confirmed that treatment of nanofluids in colon cancer cells does not damage immune-induced substances unlike treatment of active oxygen. According to the research team's research on mice that caused lung cancer, the weight of tumors decreased by 97 percent compared to when immuno-tube inhibitors were administered alone. The findings were published in the online edition of the international journal Advanced Materials on Thursday.

- The research team of Kim Tae-sung, mechanical engineering professor, At room temperature and pressure using nanofunction
- The research team of Kim Tae-sung, a mechanical engineering professor, At room temperature and pressure using nanofunction Development of Composite Technology for Isulfurized Tungsten in octave - by using plasma chemical weather deposition method to synthesize cold, face-to-face areas Identify the possibility of alternative catalysts of platinum for mass production and water transfer - 2.13 Selected as 'Small' Back Cover, an international journal of nanoscience and microscience The research team led by Professor Kim Tae-sung of the Department of Mechanical Engineering (Joint 1st author Kim Hyung-woo, Vinit Kanade, and Kim Man-soo) jointly developed the technology called "Iranium Tungsten (1T-WS2) Thin Film Growth and Efficient and Reliable Hydrogen Occurrence Response" with the research team of Professor Lee Jae-hyun of Ajou University. Transition Metal Dichalcogenides is a compound of several metastatic metals on the periodic table and of the 16 calcongen elements except oxygen, sulphur (S), selenium (Se), and telenium (Te), which have multiple structures, and are expected to change by conductors, semiconductors, and materials, unlike graphenes, which have a single structure. In particular, unlike the transfer metal calcogen compound (2H), which is stable under conditions of room temperature and pressure, the transfer metal calcogen compound (1T) has the properties of conductors, which is highlighted as an energy electrochemical catalyst material that can replace expensive platinum catalyst with high catalyst reactivity and low resistance unique to transfer metals. The research team utilized plasma technology to secure stability and productivity, which was a major obstacle to commercialization of isulfurized tungsten materials with octave structure (quasi-anal features). In 2015, the plasma chemical weather deposition method (PECVD) was used to successfully synthesize diulfide molybdenum in a face-to-face manner at low temperatures, drawing great attention from academia and industry. Subsequently, through collaboration with Ajou University's research team, it synthesized a dissulfurized molybdenum-graphenic interconnection structure and implemented a metal-forming octane tungsten on a face-to-face board for the first time in the world. The research team successfully improved catalyzed reactivity by inducing high surface energy by making the size of the composed dioxide tungsten crystals in nanoscale so that the structure of the octave, which is quasi-normal at room temperature and pressure, can be maintained continuously after more than 1,000 electrochemical reactions, and by inducing high density crystallization. This research is expected to be applied to various metastatic metallic calcogen compounds (1TH) in the future, with the results of research by mid-sized research (NRF-2017R1A2A2B3011222), individual basic research support projects (NRF-2018R1A1A1B07040292), and President Post-Doctor Fellowship (NRF- 2014R1A6A4A4A0404A040404019). The study was published in a February 13 issue of Small, an international journal of nanoscience and microscience (IF:10.856, top 10 percent of JCRs).

- Research team led by Professor Bang Chang-hyeon Developed Energy Devices that are charged by wind alone
- Research team led by Professor Bang Chang-hyun of the Department of Chemical Engineering, Development of Energy Devices that are charged by wind alone The Korea Research Foundation said Wednesday that a research team led by Cho Seong-beom, a doctor at the Korea Ceramic Technology Institute, and Bang Chang-hyun, a professor at Sungkyunkwan University, have developed an energy device that can greatly enhance the efficiency of friction electricity. There has been a growing interest in the "Energy Harvesting" industry recently, which harvests and uses the discarded magnetic energy as a power source in everyday life, such as vibrations, heat and wind, like smart watches that charge with body heat and vehicle vibrations. In particular, low-power electronic devices are key technologies in IoT and wearable healthcare. Among them, nanogenerators using friction electricity generated by contact with objects are being actively researched, but only when two objects make contact vertically can they react to increase efficiency. The research team came up with a nanometer-thick structure that resembles hair that can harvest energy from all directions. The hair-shaped structure is attached to the friction electric device, allowing it to detect horizontal movements as well as vertical movements by switching to vibrations. When the device was attached to the fabric, it was found that it responded to a very small horizontal force of less than 0.2Pa (pascal) or less, which is only about a fifth of the force needed to open the crumpled bill. In addition, even the small wind that shook the collar caused friction electricity. The team explained that the hair mimicked the principle of inducing friction electricity by vibrating even in non-contact movements such as wind without direct contact with objects. It will contribute to the development of devices that supply power to ultra-small Internet of Things devices and biometric devices, said Dr. Cho Seong-beom. The research results were published in the cover article of the international journal Advanced Materials on Wednesday. sources : https://www.yna.co.kr/view/AKR20200213086600063?input=1195m
