HIV 치료법 개발 '주목'

HIV 치료, 바이러스 억제 넘어 ‘제거’ 방법 찾았다- 부경대 곽민석·영남대 진준오 교수팀 성과 … 코로나바이러스에도 활용 가능△ 면역증강 핵산나노입자의 HIV 대항 면역활성 전략 모식도. 인체면역결핍바이러스(HIV) 치료를 위해 바이러스를 억제하는 현재의 치료법을 넘어 바이러스를 제거할 수 있다는 연구결과가 나와 주목받고 있다. 한국연구재단은 부경대학교 곽민석 교수(화학과)와 영남대학교 진준오 교수(의생명공학과) 연구팀이 면역활성 유도 핵산나노입자를 개발했다고 밝혔다. HIV 감염환자의 면역세포가 외부 침입물로 인식할 합성 핵산분자를 제작해 면역세포를 활성화하고 감염된 세포를 제거하는 것이 연구의 핵심이다. HIV에 감염되면 면역체계가 손상돼 병원균 침입에 취약해지기 때문에 바이러스를 제거해 손상된 면역체계를 회복하는 것이 가장 중요하지만, 현재의 항바이러스 치료법은 바이러스를 억제하고 면역기능을 회복 유지하는 데 그치는 한계가 있다. 연구팀은 구(球)형으로 자가조립 될 수 있는 지질핵산염기에 면역증강 서열이 결합된 지질 DNA 분자들이 뭉치는 원리로 직경 약 14nm(나노미터·10억분의 1미터)의 면역증강 핵산나노입자를 설계, 합성했다. 이 핵산나노입자는 면역세포를 자극하는 CpG 염기서열을 가진 핵산에 인공 지질구조를 더해 설계돼 지질이중막 구조의 세포막을 효과적으로 통과할 수 있는 것은 물론, 자가조립 성질을 가져 약물 전달체가 필요 없는데다 여러 지질 핵산이 구형으로 응집한 작은 나노구조로 균일하게 만들어진 것이 특징이다. 연구팀은 HIV 감염 환자의 혈액을 이용한 실험을 통해 이 핵산나노입자의 면역세포 활성화 능력과 항바이러스 효과를 확인했다. 핵산나노입자가 환자 혈액에 있는 백혈구의 활성을 유도하고, 바이러스에 대항하는 특화된 수지상세포를 자극해 바이러스와 싸울 수 있는 사이토카인 단백질을 대량으로 분비시키는 것으로 나타났다. 부경대 곽민석 교수는 “이번에 개발한 핵산나노입자는 바이러스 치료를 위한 다양한 면역활성을 유도하는 것으로 확인돼 HIV뿐만 아니라 코로나바이러스에도 효과적인 치료제로 활용할 수 있을 것으로 기대한다.”라고 밝혔다. 한편 이번 연구는 과학기술정보통신부와 한국연구재단이 추진하는 중견연구지원사업 등의 지원으로 수행됐으며, 바이오 소재 분야 국제학술지 <바이오머티리얼스(Biomaterials)>에 8월 27일 게재(온라인)됐다. <부경투데이> △ 지질 DNA 면역활성 분자의 세포막 상호작용 분자 동역학 연구. △ 핵산나노입자의 면역세포 활성화 및 HIV 제거와 잠복기 전환 효과.

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

Jay Liu | Develops a ‘Korean hydrogen supply chain designing platform’

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

Materials Today is a world authority on academic journals with an Impact factor (IF) of 26.416, which ranks in the top 2.8% of the journal ranking index (JCR). Professor Kwak published his thesis 'Dynamic DNA-based biomaterials interacting with external, macroscopic, and molecular stimuli' in the latest issue of the journal. His thesis has been recognized by academia for its outstanding research achievements as a general thesis covering research on dynamic DNA-based biomaterials, introducing basic principles related to medicine and science, and reviews on recent developments in the field. In this paper, Professor Kwak suggested that nucleic acids enzymes compounded by chemical reactions, such as oligonucleotides (oligo), can be mass-produced and can be applied by freely changing the chemical structure and giving new physical properties. As an example, he presented fluorescent DNA and primers, which are essential raw materials for the COVID-19 diagnostic kit. Subsequently, he observed that substances such as oligonucleotides are programmed by nucleic sequence and dynamically interact in response to various stimuli, such as chemical and enzymatic reactions, systemic pH and temperature, complementary sequence and nucleic acid fuel, ligand-receptor and RNA aptamer, and external energy (light and magnetic fields). "I expect that the results of this research, conducted in collaboration with researchers in Germany and China, will provide a vast source of comprehensive information to researchers in related fields," professor Kwak said.

Wang Je-Pil | Developing domestic own production technology for ‘magnesium oxide’, an import-dependent new material

Developing domestic own production technology for ‘magnesium oxide’, an import-dependent new materialProfessor Wang Je-Pil    As the development of an independent technology for domestic production of Magnesium oxide (MgO), a new ceramic material that relies on imports for most of the domestic demand, is being promoted and it is attracting public attention. The research team (Chief Prof. Wang Je-Pil · Metallurgical Engineering) supervised by Pukyong National University in Busan has been selected for the 'Pilot project of domestic production for magnesium-based ceramic raw materials', which is an industrial technology innovative project by the Ministry of Trade, Industry and Energy for 2021, and the team will be provided 5.2 billion won for technology development by 2025 and plan forward for developing technology. In addition to the leading institution Pukyong National University, researchers such as Korea Institute of Geoscience and Mineral Resources, JPS Co., Ltd., Orient Ceramic Co., and Silla University, as well as technological innovation actors such as corporations and universities, jointly participate in the project. The goal of this project is to research ‘manufacturing technology for magnesium oxide using waste refractory materials containing magnesium and technology development for applied products using it’. This is to build a domestic production base for magnesium-based ceramic raw materials to strengthen the global competitiveness of materials supply and demand industries.Magnesium oxide is a new ceramic material widely used in refractory materials (materials that can withstand high temperatures) in furnaces that manufacture steel, catalysts, adsorbents, glass, and medical supplies, however, more than 90% of domestic demand depends on imports, and even that amount is far below the supply. Under such conditions, the research team presented the idea of recycling magnesium oxide from waste refractory materials. According to the team's idea, magnesium oxide is recovered from waste refractory materials and re-created as a high-value material through processing. Based on the research results, screening, grinding, and iron removal processes of magnesium oxide-based refractories are reviewed, and powder manufacturing processes such as magnesium compounds are developed through physical and chemical treatment of the separated magnesium oxide powder. The powder processed in this way can be used as a refractory material or an auxiliary raw material for iron making. In addition, the research team will develop a high-functional ceramic filter manufacturing technology using magnesium oxide. It plans to develop a ceramic filter for removing impurities from aluminum molten metal mixed with magnesium oxide and a ceramic membrane technology for water treatment.  연구진  왕제필 교수 jpwang@pknu.ac.kr  공과대학 화학야금 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

His thesis has been recognized by academia for its outstanding research achievements as a general thesis covering research on dynamic DNA-based biomaterials, introducing basic principles related to medicine and science, and reviews on recent developments in the field. In this paper, Professor Kwak suggested that nucleic acids enzymes compounded by chemical reactions, such as oligonucleotides (oligo), can be mass-produced and can be applied by freely changing the chemical structure and giving new physical properties. As an example, he presented fluorescent DNA and primers, which are essential raw materials for the COVID-19 diagnostic kit. Subsequently, he observed that substances such as oligonucleotides are programmed by nucleic sequence and dynamically interact in response to various stimuli, such as chemical and enzymatic reactions, systemic pH and temperature, complementary sequence and nucleic acid fuel, ligand-receptor and RNA aptamer, and external energy (light and magnetic fields). "I expect that the results of this research, conducted in collaboration with researchers in Germany and China, will provide a vast source of comprehensive information to researchers in related fields," professor Kwak said. Professor Kwak specializes in DNA synthesis and materials science and is actively researching DNA-based gene therapy for cancer, infectious diseases, and immunotherapy.    연구진  곽민석 mkwak@pukyong.ac.kr  자연과학대학 나노화학혼성재료연구실

Wang Je-Pil | Developing domestic own production technology for ‘magnesium oxide’, an import-dependent new material

Developing domestic own production technology for ‘magnesium oxide’, an import-dependent new materialProfessor Wang Je-Pil    As the development of an independent technology for domestic production of Magnesium oxide (MgO), a new ceramic material that relies on imports for most of the domestic demand, is being promoted and it is attracting public attention. The research team (Chief Prof. Wang Je-Pil · Metallurgical Engineering) supervised by Pukyong National University in Busan has been selected for the 'Pilot project of domestic production for magnesium-based ceramic raw materials', which is an industrial technology innovative project by the Ministry of Trade, Industry and Energy for 2021, and the team will be provided 5.2 billion won for technology development by 2025 and plan forward for developing technology. In addition to the leading institution Pukyong National University, researchers such as Korea Institute of Geoscience and Mineral Resources, JPS Co., Ltd., Orient Ceramic Co., and Silla University, as well as technological innovation actors such as corporations and universities, jointly participate in the project. The goal of this project is to research ‘manufacturing technology for magnesium oxide using waste refractory materials containing magnesium and technology development for applied products using it’. This is to build a domestic production base for magnesium-based ceramic raw materials to strengthen the global competitiveness of materials supply and demand industries.Magnesium oxide is a new ceramic material widely used in refractory materials (materials that can withstand high temperatures) in furnaces that manufacture steel, catalysts, adsorbents, glass, and medical supplies, however, more than 90% of domestic demand depends on imports, and even that amount is far below the supply. Under such conditions, the research team presented the idea of recycling magnesium oxide from waste refractory materials. According to the team's idea, magnesium oxide is recovered from waste refractory materials and re-created as a high-value material through processing. Based on the research results, screening, grinding, and iron removal processes of magnesium oxide-based refractories are reviewed, and powder manufacturing processes such as magnesium compounds are developed through physical and chemical treatment of the separated magnesium oxide powder. The powder processed in this way can be used as a refractory material or an auxiliary raw material for iron making. In addition, the research team will develop a high-functional ceramic filter manufacturing technology using magnesium oxide. It plans to develop a ceramic filter for removing impurities from aluminum molten metal mixed with magnesium oxide and a ceramic membrane technology for water treatment.  연구진  왕제필 교수 jpwang@pknu.ac.kr  공과대학 화학야금 연구실
