研究室紹介
Professor Jong In Han's research lab specializes in advanced materials chemistry with a focus on sustainable surface engineering and environmental remediation. The lab develops eco-friendly electroplating processes, such as non-cyanide gold plating for electronic packaging, and investigates metal-thiol complexes for selective nitric oxide capture in flue gas. Key research directions include the kinetics and stability of metal complexes under oxidative conditions, particularly Fe(II)–thiol systems that resist oxygen interference. The lab also explores fundamental electrokinetics and reaction mechanisms in non-aqueous and complexed environments for industrial applications.

2Gold electroless plating for surface finishing of electronic circuits, named electroless nickel immersion gold (ENIG), is widely practiced in the electronics packaging industry. Noncyanide substitutions of the current cyanide bath for immersion gold are being sought for environmental and safety reasons. Herein, as a promising option, a bath using a noncyanide gold complex, Au(I)–thiourea, was developed. The kinetics of gold deposition were estimated with respect to gold concentration, thiourea c
Iron(II) thiochelates, especially iron(II) 2,3-bis(sulfanyl)propane-1-sulfonate (Fe(II)(DMPS)2), have received particular attention as nitric oxide (NO) absorbents because they maintain high NO removal efficiency even in the presence of O2 in flue gases. Herein, we explored the O2-inducing oxidation kinetics of Fe(II) and thiol groups (R–SH) in Fe(II)(DMPS)2 and analyzed the resultant products to understand the resistive behavior toward O2. Quantitative analysis revealed that 4 mM of Fe(II) in 1
