Title of Speech: Development of hollow fiber membrane modules with a thin-film composite structure for CO2 capture and the gas separation performance
Abstract: Global warming and climate change are serious global problems that we are facing today, and urgent action is required. Carbon Capture, Utilization and Storage (CCUS) technology has been internationally recognized as the most effective method, along with the development of energy-saving technologies and the promotion of the use of renewable resources. CCUS is a range of technologies designed to capture CO2 from large sources of CO2 emissions, such as thermal power plants and steelworks, before it is released into the atmosphere and use it effectively as a valuable resource, or transport it by pipeline etc. to a storage site and inject it into underground or sub-seabed aquifers. Demonstration tests of CCS are currently underway at around 80 sites around the world, and 40 Mt of CO2 was stored by 2020. However, to achieve the Paris Agreement's goal of keeping the average global temperature increase at the end of this century to less than 1.5 °C above pre-industrial levels, 5 Gt of CO2 will need to be stored by 2050, which is a very high hurdle. This is due in part to the high cost of CO2 capture (around 40% of the cost of CCS, Fig. 1) as well as the social acceptance of the project .

Title of Speech: Upcycling of waste plastic into porous carbon materials and their application to greenhouse gas capture
Abstract: Because of the development of industry and the increase in the use of fossil fuels, the concentration of CO2, a greenhouse gas considered to be the main cause of global warming, is steadily increasing. Among various CO2 reduction efforts, carbon dioxide capture and storage (CCS) technologies are being developed and applied in various forms. Analyzing the CCS technology, it takes 70% or more of the cost in the capture stage, so it is necessary to develop an efficient capture technology for an applicable CCS technology. Among various CO2 capture methods, adsorption has the advantages of low energy consumption, flexible process operation, and easy scale-up. Materials such as zeolite, activated carbon, and metal organic framework are being considered adsorbents for capturing CO2. Porous carbon materials have the advantages of being inexpensive, having excellent thermal/chemical stability, and being able to control the pore structure by varying treatment conditions. This talk will introduce research on synthesizing porous carbon materials with micropores through carbonization and activation of waste plastic discarded after use and applying them to CO2 adsorption. In addition, research on the application of waste plastic-based porous carbons to the capture of other greenhouse gases will be discussed.

Title of Speech: Plasmonic tungsten oxide nanocrystal thin films for next-generation electrochromic windows
Abstract: Indoor thermal regulation is highly important in the building and transportation sectors, as it can reduce heating and cooling energy consumption. Classical electrochromic windows can modulate light transmittance by applying electrochemical potential, which primarily alters visible light modulation through polaronic absorption behavior. However, near-infrared modulation is limited in classical materials. In this presentation, plasmonic tungsten oxide nanocrystals, which exhibit near-infrared modulation due to localized surface plasmon resonance, will be discussed for electrochromic applications. To enhance electrochromic modulation, the crystalline structure and shape anisotropy of tungsten oxide nanocrystals have been studied in detail. First, different crystalline sites exhibit distinct optical activity, leading to the conclusion that different electrolytes produce varying modulation effects. Second, the impact of crystalline anisotropy in hexagonal cesium-doped tungsten oxide nanorods and nanoplatelets on key electrochromic metrics will be explored. Lastly, synthetic approaches to maximize the electrochromic modulation of tungsten oxide nanocrystals will be presented.

Title of Speech: Functional Carbon Composites with High Mechanical Strength
Abstract: Carbonaceous materials (graphite, CNT, graphene) were modified by Ion Assisted reaction (IAR) in which Ar+ Ion beam is irradiated on the bare carbon powders with reactive gas environments in order to add new hydrophilic functional groups (-OH, - COOH, -CO, NH2, etc.). And metal nanoparticles (Cu, Ag, Ni, Zn, Cu/Zn alloy etc.) on the powders (NPP) are synthesized in physical vapor deposition system to add new metallic functions (antimicrobial, magnetic, electrical conductivity, etc.) in which the metal are deposited on the rotating the powders. The modified carbon powders by IAR and NPP were easily dispersed in water, organic solvent, and any polymer matrices. The carbon composites were synthesized by conventional hot melting process with mixing of the polymer and the modified carbonaceous powders. and their characteristics with various concentrations of powder addition were investigated. Mechanical properties of the polymer composite were not changed much until addition of 40wt.% of graphite, in which graphite polymer composite by conventional chemical surface modification of carbon possesses rapid drops of mechanical properties. Control of the electrical conductivity and thermal conductivity of the composite were successfully carried out by Ni magnetic metal nanoparticles on carbon fiber addition. Physical properties of the composites especially thermal and electrical conductivity, and mechanical properties were explained comparing with the data fabricated by conventional chemical process. Applications of the carbon added composite were presented in terms of fuel cell bipolar plate, LED heat sink, electronic enclosure, etc. and R&D directions of the carbon addition into metal, ceramic and polymer matrices were suggested what we want to cooperate.
