The KSLV-II (Korea Space Launch Vehicle-II) Nuri launched on June 21st, 2022. The Nuri vehicle used kerosene as fuel and the cryogenic liquid oxygen as oxidant. The management cryogenic liquid oxygen is required during the development of the NURI. Such as leveling the liquid oxygen tank, natural circulation...
Discovery of new molecules and materials with desired properties is a practical goal of chemical research. A promising way to significantly accelerate the latter process is to incorporate all available knowledge and data to plan the synthesis of the next materials. In this talk, I...
In this talk, I will present nanoscale transport phenomena driven by solute or temperature difference. Firstly, I will demonstrate that the liquid flow can be generated by various types of solutes within nanochannels. The underlying mechanism for interfacially driven flow is closely associated with the molecular interactions between...
To limit global warming to well below 2°C within this century, we must reach net-zero carbon emissions by 2050. Merely curbing fossil fuel consumption will not suffice, given the anticipated surge in global energy demand. While nuclear and renewable energy sources like photovoltaics are considered...
Interfacial engineering for advanced electrochemical devices Hee-Tak Kim Department of Chemical and Biomolecular Engineering, KAIST In recent decades, electrochemical devices, including batteries, fuel cells, and electrolysis, have made significant strides. However, their progress is often hindered by various interfacial problems that are challenging to identify and address. Space charges, double layer charges, charge transfer, and mass transport intricately influence the performance and durability of electrochemical devices. The complexity of interfaces and the limited means available for characterizing interface structures often result in unresolved or overlooked interfacial issues. This seminar emphasizes the importance of interfacial engineering and provides a fundamental understanding of electrode/electrode, electrolyte/electrolyte, and electrode/electrolyte interfaces. Based on this understanding, case studies are presented to demonstrate how to leverage this knowledge and control interface structures for designing advanced electrochemical devices....
