Jung Sung-Chul | Paper on Journal of RSC

PKNU researchers have found a way to improve the efficiency of lithium-sulfur batteriesProfessor Jung Sung-Chul    A research team led by Professor Jung Sung-Chul (Dept. of Physics) at Pukyong National University succeeded in discovering the ion transport mechanism of a metal organic framework that can increase the efficiency of lithium-sulfur secondary batteries. Professor Jung and researcher Jeon Tae -Gon (Department of Physics · Research Center for Nano Science and Technology) have identified the mechanism at the atomic-level by which the HKUST-1 metal-organic framework-based separator blocks the movement of lithium polysulfide while effectively allowing only lithium ions to pass through. The metal-organic framework is a microporous material used in the fields of secondary batteries, hydrogen storage, catalysts, sensors, and drug delivery. Lithium-sulfur secondary batteries have a chronic shuttle phenomenon in which lithium polysulfide passes through the separator and repeatedly reciprocates between the positive and negative electrodes.Professor Jung's research team identified the fact that not only the size of the pores of the metal-organic framework, but also the solvation structure of ions or molecules passing through the metal-organic framework are important factors that can pass through the separation membrane through the first principle calculation simulation study. The presence or absence of chemical bonds between active sites and ions or molecules of the metal-organic framework was also found to be an important factor. Professor Jung said, "The results of this study can be very useful information not only to solve the shuttle phenomenon of lithium polysulfide, but also to design a metal-organic framework separator for a general liquid electrolyte-based metal-ion battery," he added, "I expect that it will also be helpful in the process of controlling the selective movement and blocking of only the target material in general microporous materials." This research was conducted with the support of the Ministry of Science and ICT (middle-level research), and has been recently published online by the Royal Society of Chemistry, (Citation Index = 12.732).

Lee Song-Yi | Paper on an international journal

PKNU, published a review paper 'Recent Strategies to Develop Innovative Photosensitizers for Enhanced Photodynamic Therapy' in this journalProfessor Lee Song-Yi A research team led by Professor Lee Song-Yi of Pukyong National University (Dept. of Chemistry, Dept. of Industry 4.0 Convergence Bionics Engineering) is attracting public attention by publishing a review paper in 'Chemical Reviews (IF=60.62)', the top international academic journal in the field of basic science. Professor Lee, Thanh Chung Pham (completed doctoral), and Choi Young-Hwan (2 years in master's program), and other research teams recently published a review paper 'Recent Strategies to Develop Innovative Photosensitizers for Enhanced Photodynamic Therapy' in this journal. ‘Chemical Reviews’ published by the Journal of the American Chemical Society (ACS Publications) is an academic journal that summarizes research trends and prospects in the field of chemistry, and is recognized as having the greatest influence among researchers in this field. In this paper, Professor Lee's research team presented a strategy to develop photosensitizers, a photoactive chemical used in photodynamic therapy, which is one of the photochemical-based treatments for diseases such as cancer and infectious diseases.The research team gained attraction by unvailing research strategy and development and application research trends and research strategies for photosensitizers, which are currently being actively conducted in relation to photodynamic therapy, which removes target tissues with light of a specific wavelength after injection of a photosensitizer for non-invasive treatment of diseases such as cancer. The research team pointed out that most of the existing papers on the development of photosensitizers focus only on nanomaterials and nanotechnology. Instead, they presented intuitive and specific insights for the development of innovative organic photosensitizers by presenting research results related to the structural design and development of organic photosensitizers for effective and improved photodynamic therapy. Professor Lee is actively conducting research on the development of Polydiacetylenes, PDAs, CDr (Continuous Depolymerization after a Reaction-based detection) and research on the design and synthesis of organic functional materials under the theme of ‘research on intelligent functional materials for signal amplification’.

Kwak Min-Seok | Found a way to eliminate the HIV virus beyond suppressing

PKNU found a way to eliminate the HIV virus beyond suppressingProfessor Kwak Min-Seok    For the treatment of human immunodeficiency virus (HIV), research results showing that the virus can be removed beyond the existing treatment that suppresses the virus is drawing attention from the public. The National Research Foundation of Korea (NRF) announced that a research team led by Professor Kwak Min-Seok (Department of Chemistry) of Pukyong National University and Professor Jin Jun-O (Department of Medical Biotechnology) of Yeungnam University has developed nucleic acid nanoparticles that induce immune activity. The core of the research is to activate the immune cells and remove the infected cells by making synthetic nucleic acid molecules that the immune cells of HIV-infected patients will recognize as antigen. When infected with HIV, the immune system gets damaged, making it vulnerable to pathogen entry, so it is most important to remove the virus and restore the damaged immune system. However, current antiviral therapy has limitations in suppressing the virus and restoring and maintaining immune function. The research team planned and synthesized immune-enhancing nucleic acid nanoparticles with a diameter of about 14 nm (nanometer, one billionth of a meter) based on the principle of aggregation of lipid DNA molecules with immune-enhancing sequences bound to lipid nucleic acid groups that can be self-assembled in a spherical shape.These nucleic acid nanoparticles can effectively pass through the cell membrane of the lipid bilayer structure by adding an artificial lipid structure to the nucleic acid having the CpG sequence that stimulates immune cells. In addition, since it has self-assembly properties, it does not require a drug carrier and is characterized by uniformly made small nanostructures in which various lipid nucleic acids are aggregated in a spherical shape. The research team proved the immune cell activation ability and antiviral effect of these nucleic acid nanoparticles through experiments using the blood of HIV-infected patients. As a result, it was shown that the nucleic acid nanoparticles induce the activity of white blood cells in the patient's blood, stimulate the specialized dendritic cells to fight the virus, and secrete a large amount of cytokine protein that can fight the virus. Professor Kwak Min-Seok of Pukyong National University said, "As the nucleic acid nanoparticles developed this time have been confirmed to induce various immune activities for virus treatment, we expect that it can be used as effective treatment for not only HIV but also coronavirus."

Chae Su-Jong | Developed high-capacity silicon (Si)/carbon nanocomposite anode materials that are '5 times stronger than graphite'

PKNU developed high-capacity silicon (Si)/carbon nanocomposite anode materials that are '5 times stronger than graphite'Professor Chae Su-Jong  A silicon/carbon composite anode material with a capacity that is five times higher than that of graphite, which is the existing anode material for next-generation secondary batteries, has been developed and is attracting academia's attention. Pukyong National University announced that a research team led by Professor Chae Su-Jong (Dept. of Industrial Chemistry) has recently developed a high-capacity porous silicon/carbon composite anode material. Professor Chae's research team developed porous silicon with a large specific surface area (surface area per unit volume) of 972 m2/g by forming micrometer (μm)-sized particles of silicon primary particles smaller than 4 nanometers (nm). Porous silicon has a structural advantage in that it can effectively control depletion due to the volume expansion that occurs when lithium is stored. However, when the size of silicon is reduced to a few nanometers or less, there was a problem in that the size of the silicon primary particles easily increases due to the sintering phenomenon (A process in which particles undergo depleting activation and become one united body) or there was a problem of lost in the internal pore (gaps between the particles).Professor Chae's research team went through this problem by making pitch extracted from crude oil (black grounds left after distilling crude oil or coal tar) uniformly soak into the porous silicon. As a result of analysis by the research team with a real-time transmission electron microscope, the pitch existing inside the porous silicon was carbonized and suppressed the sintering of silicon at high temperatures. In addition, this carbonized pitch was found to prevent extreme volume change and depletion of silicon during battery operation. It was confirmed that the developed porous silicon/carbon composite anode material has about five times the capacity of graphite anode material. Especially, in the evaluation of the full cell, it maintained 80% of its initial capacity even after 450 charging and discharging, showing 10 times of the lifespan compared to the porous silicon/carbon composite, which did not overcome the sintering phenomenon. Professor Chae conducted research jointly with Dr. Jason Zhang's research team at Pacific Northwest National Laboratory (PNNL) in the US, and the results of this research have been published online in the latest issue of , an international journal in the field of materials science.    연구진  채수종 schae@pknu.ac.kr  공과대학 에너지소재 및 시스템 연구실

Hwang Geon-Tae | Develops a device that generates and stores electricity by itself in the human body

PKNU develops a device that generates and stores electricity by itself in the human bodyProfessor Hwang Geon-Tae A ‘self-chargeable flexible energy harvesting and storage device’ that can be planted in the human body to generate and store electrical energy with only small movements of muscles has been developed and is attracting public attention.Pukyong National University announced that a research team led by Professor Hwang Geon-Tae (Dept. of Materials Engineering) at Pukyong National University has developed a new concept of energy harvesting & storage integrated device that can produce and store electrical energy by itself in collaboration with a team of Professor Yoon Woon-Ha of Korea Institute of Materials Science, Professor Lee Keon-Jae of KAIST, a team of Professor Ryu Jung-Ho of Yeungnam University, and Professor Park Jung-Hwan of Kumoh National Institute of Technology. Energy harvesting, which has recently built up public attention, is a renewable energy technology that collects wasted energy around us and converts it into useful electrical energy. In this study, his research team implemented a ceramic-based flexible self-charging energy storage system that can efficiently store electrical energy by producing electrical energy with small movements of muscles. The research team improved energy storage efficiency by making nanometer (nm) grains of Pb(Mg1/3Nb2/3)O3·PbTiO3(PMN-PT), a ferroelectric ceramic, for effective energy storage and succeeded in allowing the release of stored energy to generate in several hundred nanoseconds. As the system developed this time achieves a much higher energy output density compared to conventional batteries, it is expected that it can be applied to bio-implantable cardiac defibrillators that require a large amount of instantaneous energy. In particular, wearable devices represented by smartwatches are expected to advance into body-attachable and bio-implantable technologies in the future, if the technology developed by the research team is well utilized, smart healthcare that monitors basic health conditions such as heart rate in real-time is expected to be possible. Batteries widely used to power wearable devices have limitations in requiring repeated charging or replacement due to capacity problems. On the contrary, the self-charging energy storage system developed by the research team this time is thin and easily bendable, so it is easy to apply to wearable devices, and it can generate and store electric energy by itself, making it possible to replace or supplement existing batteries. The research was carried out with support from the National Research Foundation of Korea, and the paper 'Flexible Self-Charging, Ultrafast, High-Power Density Ceramic Capacitor System' containing the research results was published in (IF: 23.1), a global energy-related journal recently. Meanwhile, Professor Hwang Geon-Tae is actively conducting research in the field of energy harvesting by publishing his thesis as a corresponding author in the international academic journal (IF: 38.5).    연구진  황건태 gthwang@pknu.ac.kr  공과대학 기능성 세라믹 소재 및 소자 연구실

PKNU develops a ‘Korean hydrogen supply chain designing platform’Professor Jay Liu    Pukyong National University is attracting public attention for participating in the development of a Korean hydrogen supply chain designing platform based on artificial intelligence (AI). Pukyong National University announced that the university was selected as a home for a new task, the Basic Research Laboratory in the year 2021, by the Ministry of Science and ICT under the supervision of Professor Jay Liu's (Dept. of Chemical Engineering) research team. Pukyong National University, in collaboration with Kyunghee University, Ewha Womans University, Ulsan Technopark, and the Korea Hydrogen Industry Association (KHIA), will receive 1.1 billion won by 2024 to promote the development of a 'Sustainable AI-based Real-Time Dynamic Korean Hydrogen Supply Chain Designing platform'. The goal of this study is to develop a platform that designs an optimization model for the entire hydrogen supply chain, including production, storage, transportation, and supply management in real-time, which has been attracting attention as a next-generation fuel.If this platform is developed, we can derive optimal results online (web) in real-time, it will use data from the entire hydrogen supply chain to determine where to produce and at what scale, how to build a hydrogen production base, how to produce it, what method and route it should be transported, and where the hydrogen charging station should be located. Above all, the development of a web-based platform that utilizes a real-time artificial intelligence-based dynamic hydrogen supply chain design and analyzes supply chain business models is the first research attempted in Korea as well as in the world. In this study, the Pukyong National University's research team plans to develop a Korean hydrogen supply network platform with high-level accuracy to the eup, myeon and dong (neighborhood administrative areas) regions using GIS (Geographical Information System) as a research target in South and North Gyeongsang Province. Jay Liu, the chief professor responsible for the research said, "From the point of view of the revitalization of the hydrogen economy and national energy transition, I think that supply chain design, such as securing and operating the infrastructure for the entire hydrogen supply process, is very important," he added, "I expect that this research will be able to develop an efficient hydrogen technology nurturing policy and investment strategy, and ultimately contribute to the establishment of cost-effective energy conversion policies."    연구진  유준 jayliu@pknu.ac.kr  공과대학 지능시스템연구실

Hwang Jae-Yeol | Develops a high-performance 2D thermoelectric thin-film that 'sticks to plastics and glass'

PKNU develops a high-performance 2D thermoelectric thin-film that 'sticks to plastics and glass'Professor Hwang Jae-Yeol    A technology that can transfer a high-performance two-dimensional thermoelectric Membrane to semiconductor substrates (wafer), as well as plastic or glass, which is attracting attention as a next-generation energy conversion device, has been developed. Professor Hwang Jae-Yeol (Dept. of Physics) at Pukyong National University, together with Professor Kim Sung-Wng (Department of Energy Science) at SungKyunKwan University, developed a technology that can separate and apply a high-performance two-dimensional thermoelectric thin film from a substrate, and recently published their findings in the world-renowned scientific journal (ACS Energy Letters, IF 23.101)>. A Thermoelectric Membrane is a thin film made of thermoelectric material that converts heat into electrical energy. It is a next-generation device that can be applied to wearable devices, the Internet of Things, and smart sensors. Research related to this has been increasing since the recent discovery of excellent properties in 2D thin films. Professor Hwang's research team has developed a technology that can achieve exceptional thermoelectric energy conversion efficiency by growing (forming) a thin film through an epitaxial process (vdWE: spontaneous van der Waals epitaxy), then separating the epitaxial thin-film from the growth substrate without damage and transferring it onto a curved surface or a flat surface.The research team succeeded in transforming a pseudo-morphic Te (tellurium) monolayer on the surface of a sapphire substrate and grown as a BST membrane. At the same time, they made the substrate and the film weakly bond through an epitaxy process using the van der Waals force, an interaction between atoms, and selectively removed this bond using a solvent to maintain the crystal structure while minimizing the loss of physical properties. Professor Hwang said, "Through this research, high-performance two-dimensional thermoelectric thin-films, which could only be grown on limited substrates, can be transferred and utilized not only on the substrates but also on various types of materials such as plastics and glass. In this regard, this study suggested the development of a new concept device and the possibility of the new application of the 2D thin-film." "As this research is based on the surface properties of sapphire substrates widely used in semiconductor and electronic fields, I am expecting that various applications of this technology can be applied in the future, and high-performance thin-film energy devices that can be used in wearable devices can be developed," he added.   연구진  황재열 jaeyeol@gmail.com  자연과학대학 스마트소재물성연구실

Jung Sung-Chul | Paper on Journal of RSC

PKNU researchers have found a way to improve the efficiency of lithium-sulfur batteriesProfessor Jung Sung-Chul    A research team led by Professor Jung Sung-Chul (Dept. of Physics) at Pukyong National University succeeded in discovering the ion transport mechanism of a metal organic framework that can increase the efficiency of lithium-sulfur secondary batteries. Professor Jung and researcher Jeon Tae -Gon (Department of Physics · Research Center for Nano Science and Technology) have identified the mechanism at the atomic-level by which the HKUST-1 metal-organic framework-based separator blocks the movement of lithium polysulfide while effectively allowing only lithium ions to pass through. The metal-organic framework is a microporous material used in the fields of secondary batteries, hydrogen storage, catalysts, sensors, and drug delivery. Lithium-sulfur secondary batteries have a chronic shuttle phenomenon in which lithium polysulfide passes through the separator and repeatedly reciprocates between the positive and negative electrodes.Professor Jung's research team identified the fact that not only the size of the pores of the metal-organic framework, but also the solvation structure of ions or molecules passing through the metal-organic framework are important factors that can pass through the separation membrane through the first principle calculation simulation study. The presence or absence of chemical bonds between active sites and ions or molecules of the metal-organic framework was also found to be an important factor. Professor Jung said, "The results of this study can be very useful information not only to solve the shuttle phenomenon of lithium polysulfide, but also to design a metal-organic framework separator for a general liquid electrolyte-based metal-ion battery," he added, "I expect that it will also be helpful in the process of controlling the selective movement and blocking of only the target material in general microporous materials." This research was conducted with the support of the Ministry of Science and ICT (middle-level research), and has been recently published online by the Royal Society of Chemistry, (Citation Index = 12.732).

Lee Song-Yi | Paper on an international journal

Professor Lee, Thanh Chung Pham (completed doctoral), and Choi Young-Hwan (2 years in master's program), and other research teams recently published a review paper 'Recent Strategies to Develop Innovative Photosensitizers for Enhanced Photodynamic Therapy' in this journal. ‘Chemical Reviews’ published by the Journal of the American Chemical Society (ACS Publications) is an academic journal that summarizes research trends and prospects in the field of chemistry, and is recognized as having the greatest influence among researchers in this field. In this paper, Professor Lee's research team presented a strategy to develop photosensitizers, a photoactive chemical used in photodynamic therapy, which is one of the photochemical-based treatments for diseases such as cancer and infectious diseases.The research team gained attraction by unvailing research strategy and development and application research trends and research strategies for photosensitizers, which are currently being actively conducted in relation to photodynamic therapy, which removes target tissues with light of a specific wavelength after injection of a photosensitizer for non-invasive treatment of diseases such as cancer. The research team pointed out that most of the existing papers on the development of photosensitizers focus only on nanomaterials and nanotechnology. Instead, they presented intuitive and specific insights for the development of innovative organic photosensitizers by presenting research results related to the structural design and development of organic photosensitizers for effective and improved photodynamic therapy. Professor Lee is actively conducting research on the development of Polydiacetylenes, PDAs, CDr (Continuous Depolymerization after a Reaction-based detection) and research on the design and synthesis of organic functional materials under the theme of ‘research on intelligent functional materials for signal amplification’.

The core of the research is to activate the immune cells and remove the infected cells by making synthetic nucleic acid molecules that the immune cells of HIV-infected patients will recognize as antigen. When infected with HIV, the immune system gets damaged, making it vulnerable to pathogen entry, so it is most important to remove the virus and restore the damaged immune system. However, current antiviral therapy has limitations in suppressing the virus and restoring and maintaining immune function. The research team planned and synthesized immune-enhancing nucleic acid nanoparticles with a diameter of about 14 nm (nanometer, one billionth of a meter) based on the principle of aggregation of lipid DNA molecules with immune-enhancing sequences bound to lipid nucleic acid groups that can be self-assembled in a spherical shape.These nucleic acid nanoparticles can effectively pass through the cell membrane of the lipid bilayer structure by adding an artificial lipid structure to the nucleic acid having the CpG sequence that stimulates immune cells. In addition, since it has self-assembly properties, it does not require a drug carrier and is characterized by uniformly made small nanostructures in which various lipid nucleic acids are aggregated in a spherical shape. The research team proved the immune cell activation ability and antiviral effect of these nucleic acid nanoparticles through experiments using the blood of HIV-infected patients. As a result, it was shown that the nucleic acid nanoparticles induce the activity of white blood cells in the patient's blood, stimulate the specialized dendritic cells to fight the virus, and secrete a large amount of cytokine protein that can fight the virus. Professor Kwak Min-Seok of Pukyong National University said, "As the nucleic acid nanoparticles developed this time have been confirmed to induce various immune activities for virus treatment, we expect that it can be used as effective treatment for not only HIV but also coronavirus." The research was conducted with support from the mid-level research support project promoted by the Ministry of Science and ICT and the National Research Foundation of Korea, and was published (online) on August 27th in , which is an international academic journal of biomaterials.    연구진  곽민석 mkwak@pukyong.ac.kr  자연과학대학 나노화학혼성재료연구실

Chae Su-Jong | Developed high-capacity silicon (Si)/carbon nanocomposite anode materials that are '5 times stronger than graphite'

PKNU developed high-capacity silicon (Si)/carbon nanocomposite anode materials that are '5 times stronger than graphite'Professor Chae Su-Jong  A silicon/carbon composite anode material with a capacity that is five times higher than that of graphite, which is the existing anode material for next-generation secondary batteries, has been developed and is attracting academia's attention. Pukyong National University announced that a research team led by Professor Chae Su-Jong (Dept. of Industrial Chemistry) has recently developed a high-capacity porous silicon/carbon composite anode material. Professor Chae's research team developed porous silicon with a large specific surface area (surface area per unit volume) of 972 m2/g by forming micrometer (μm)-sized particles of silicon primary particles smaller than 4 nanometers (nm). Porous silicon has a structural advantage in that it can effectively control depletion due to the volume expansion that occurs when lithium is stored. However, when the size of silicon is reduced to a few nanometers or less, there was a problem in that the size of the silicon primary particles easily increases due to the sintering phenomenon (A process in which particles undergo depleting activation and become one united body) or there was a problem of lost in the internal pore (gaps between the particles).Professor Chae's research team went through this problem by making pitch extracted from crude oil (black grounds left after distilling crude oil or coal tar) uniformly soak into the porous silicon. As a result of analysis by the research team with a real-time transmission electron microscope, the pitch existing inside the porous silicon was carbonized and suppressed the sintering of silicon at high temperatures. In addition, this carbonized pitch was found to prevent extreme volume change and depletion of silicon during battery operation. It was confirmed that the developed porous silicon/carbon composite anode material has about five times the capacity of graphite anode material. Especially, in the evaluation of the full cell, it maintained 80% of its initial capacity even after 450 charging and discharging, showing 10 times of the lifespan compared to the porous silicon/carbon composite, which did not overcome the sintering phenomenon. Professor Chae conducted research jointly with Dr. Jason Zhang's research team at Pacific Northwest National Laboratory (PNNL) in the US, and the results of this research have been published online in the latest issue of , an international journal in the field of materials science.    연구진  채수종 schae@pknu.ac.kr  공과대학 에너지소재 및 시스템 연구실

Hwang Geon-Tae | Develops a device that generates and stores electricity by itself in the human body

PKNU develops a device that generates and stores electricity by itself in the human bodyProfessor Hwang Geon-Tae A ‘self-chargeable flexible energy harvesting and storage device’ that can be planted in the human body to generate and store electrical energy with only small movements of muscles has been developed and is attracting public attention.Pukyong National University announced that a research team led by Professor Hwang Geon-Tae (Dept. of Materials Engineering) at Pukyong National University has developed a new concept of energy harvesting & storage integrated device that can produce and store electrical energy by itself in collaboration with a team of Professor Yoon Woon-Ha of Korea Institute of Materials Science, Professor Lee Keon-Jae of KAIST, a team of Professor Ryu Jung-Ho of Yeungnam University, and Professor Park Jung-Hwan of Kumoh National Institute of Technology. Energy harvesting, which has recently built up public attention, is a renewable energy technology that collects wasted energy around us and converts it into useful electrical energy. In this study, his research team implemented a ceramic-based flexible self-charging energy storage system that can efficiently store electrical energy by producing electrical energy with small movements of muscles. The research team improved energy storage efficiency by making nanometer (nm) grains of Pb(Mg1/3Nb2/3)O3·PbTiO3(PMN-PT), a ferroelectric ceramic, for effective energy storage and succeeded in allowing the release of stored energy to generate in several hundred nanoseconds. As the system developed this time achieves a much higher energy output density compared to conventional batteries, it is expected that it can be applied to bio-implantable cardiac defibrillators that require a large amount of instantaneous energy. In particular, wearable devices represented by smartwatches are expected to advance into body-attachable and bio-implantable technologies in the future, if the technology developed by the research team is well utilized, smart healthcare that monitors basic health conditions such as heart rate in real-time is expected to be possible. Batteries widely used to power wearable devices have limitations in requiring repeated charging or replacement due to capacity problems. On the contrary, the self-charging energy storage system developed by the research team this time is thin and easily bendable, so it is easy to apply to wearable devices, and it can generate and store electric energy by itself, making it possible to replace or supplement existing batteries. The research was carried out with support from the National Research Foundation of Korea, and the paper 'Flexible Self-Charging, Ultrafast, High-Power Density Ceramic Capacitor System' containing the research results was published in (IF: 23.1), a global energy-related journal recently. Meanwhile, Professor Hwang Geon-Tae is actively conducting research in the field of energy harvesting by publishing his thesis as a corresponding author in the international academic journal (IF: 38.5).    연구진  황건태 gthwang@pknu.ac.kr  공과대학 기능성 세라믹 소재 및 소자 연구실

Hwang Jae-Yeol | Develops a high-performance 2D thermoelectric thin-film that 'sticks to plastics and glass'

PKNU develops a high-performance 2D thermoelectric thin-film that 'sticks to plastics and glass'Professor Hwang Jae-Yeol    A technology that can transfer a high-performance two-dimensional thermoelectric Membrane to semiconductor substrates (wafer), as well as plastic or glass, which is attracting attention as a next-generation energy conversion device, has been developed. Professor Hwang Jae-Yeol (Dept. of Physics) at Pukyong National University, together with Professor Kim Sung-Wng (Department of Energy Science) at SungKyunKwan University, developed a technology that can separate and apply a high-performance two-dimensional thermoelectric thin film from a substrate, and recently published their findings in the world-renowned scientific journal (ACS Energy Letters, IF 23.101)>. A Thermoelectric Membrane is a thin film made of thermoelectric material that converts heat into electrical energy. It is a next-generation device that can be applied to wearable devices, the Internet of Things, and smart sensors. Research related to this has been increasing since the recent discovery of excellent properties in 2D thin films. Professor Hwang's research team has developed a technology that can achieve exceptional thermoelectric energy conversion efficiency by growing (forming) a thin film through an epitaxial process (vdWE: spontaneous van der Waals epitaxy), then separating the epitaxial thin-film from the growth substrate without damage and transferring it onto a curved surface or a flat surface.The research team succeeded in transforming a pseudo-morphic Te (tellurium) monolayer on the surface of a sapphire substrate and grown as a BST membrane. At the same time, they made the substrate and the film weakly bond through an epitaxy process using the van der Waals force, an interaction between atoms, and selectively removed this bond using a solvent to maintain the crystal structure while minimizing the loss of physical properties. Professor Hwang said, "Through this research, high-performance two-dimensional thermoelectric thin-films, which could only be grown on limited substrates, can be transferred and utilized not only on the substrates but also on various types of materials such as plastics and glass. In this regard, this study suggested the development of a new concept device and the possibility of the new application of the 2D thin-film." "As this research is based on the surface properties of sapphire substrates widely used in semiconductor and electronic fields, I am expecting that various applications of this technology can be applied in the future, and high-performance thin-film energy devices that can be used in wearable devices can be developed," he added.   연구진  황재열 jaeyeol@gmail.com  자연과학대학 스마트소재물성연구실
