研究室紹介
Professor Jeong Jin Hong's research lab specializes in advanced materials synthesis and surface engineering, with a strong focus on nanomaterials for energy and environmental applications. Key research directions include the development of functional nanomaterials such as indium tin oxide nanoparticles for transparent conductive films, and the application of atomic layer deposition (ALD) to enhance the performance and stability of lithium-ion battery cathodes. The lab also investigates membrane-based separation processes, particularly micellar-enhanced ultrafiltration for phenol removal from aqueous streams. These efforts reflect a multidisciplinary approach combining materials science, chemical engineering, and sustainable technology.

11Micellar-enhanced ultrafiltration has been carried out to investigate the separation of phenol from an aqueous stream via hollow fiber membranes. First, phenol is solubilized into the micelles of cationic surfactant such as hexadecyltrimethylammonium chloride (CTAC) and hexadecylpyridinium chloride (CPC), and then the micellar solution is treated continuously through an ultrafiltration membrane module. In the present study we examine the effects of retentate concentration, molecular weight cut-o
Stable dispersion of colloidal indium tin oxide nanoparticles was prepared by using indium tin oxide nanopowder, organic solvent, and suitable dispersants through attrition process. Various comminution parameters during the attrition step were studied to optimize the process for the stable dispersion of indium tin oxide sol. The transparent and conductive films were fabricated on glass substrate using the indium tin oxide sol by spin coating process. To obtain antireflective function, partially
Abstract The growing demand for energy storage systems and electric vehicles has intensified research on Li-ion batteries, in which the cathode significantly influences both cost and performance. This review focuses on recent advances in atomic layer deposition (ALD) as a strategy to enhance cathode materials through surface modification and doping. Originally developed for the semiconductor industry, ALD enables conformal and precisely controlled coating on substrates with high-aspect-ratio str
