研究室紹介
Professor Myungsoo Kim's research lab specializes in advanced nanomaterials and 2D materials for next-generation electronic and energy applications. The lab focuses on developing atomically thin, non-volatile resistive switches using transition metal dichalcogenides (TMDs) and hexagonal boron nitride (hBN), emphasizing ultra-low power RF and mm-wave switching for 5G and beyond communications. Additional research directions include nanocomposite materials for fuel cell bipolar plates, carbon black catalysts for hydrogen production, and polymer membrane transport phenomena with elastic coupling effects.

15The present study reports the influence of pre-carbonization on the properties of KOH-activated coal tar pitch (CTP). The change of crystallinity and pore structure of pre-carbonized CTPs as well as their activated carbons (ACs) as function of pre-carbonization temperature are investigated. The crystallinity of pre-carbonized CTPs increases with increasing the carbonization temperature up to 600 °C, but a disorder occurs during the carbonization around 700 °C and an order happens gradually with
Abstract There are two types of anomalous diffusion of vapors in solid polymers which are held to be due to swelling. If the latter is seen as strain, then there must be an accompanying stress which can affect the nature and magnitude of diffusion. The theories of diffusion in polymers are examined in light of the network theory of Larché and Cahn. Their formalism is used to solve permeation and sorption in polymer membranes to illustrate the general features of the elastic effects, particularly
Carbon blacks were used as catalysts for hydrogen production through hydrocarbon decomposition under different operation conditions such as temperature, residence time, and hydrocarbon precursor. Those modified carbon blacks were used as reinforcement fillers in both NBR and SBR rubbers. The specific surface area of carbon black increased with low weight gain in decomposition of methane and mixture gas of meth- ane-propane caused by the protruded carbon deposits on the surface of carbon black ag
We report a study on manufacturing and characterization of a platform material for high‐performance lightweight bipolar plates for fuel cells based on nanocomposites consisting of carbon nanotubes (CNTs) and exfoliated graphite nanoplatelets (xGnPs). The experiments were designed and performed in three steps. In the preexperimental stage, xGnP‐epoxy composite samples were prepared at various xGnP weight percentages to determine the maximum processable nanofiller concentration. The main part of t
This research aims to optimize the mechanical properties of woven fabric composites, especially the elastic modulus. A micromechanics model of woven fabric composites was used to obtain the mechanical properties of the fiber composite, and a genetic algorithm (GA) was employed for the optimization tool. The structure of the fabric fiber was expressed using the width, thickness, and wave pattern of the fiber strands in the woven fabric composites. In the GA, the chromosome string consisted of the
