研究室紹介
Professor Chan-Hwa Jung's research lab specializes in the design and application of advanced nanomaterials for environmental monitoring, energy storage, and biomedical sensing. The lab focuses on developing functional 2D materials such as MXenes and graphene-based systems for enhanced surface-enhanced Raman spectroscopy (SERS) and electrochemical sensing, as well as exploring nanostructured metal alloys like Au-Cu and Pd foams for catalytic and electrochemical applications. A key research direction involves understanding the structure-property relationships of surface-functionalized nanomaterials to optimize their performance in real-world applications.

15Surface-enhanced Raman spectroscopy is a powerful and sensitive analytical tool that has found application in chemical and biomolecule analysis and environmental monitoring. Since its discovery in the early 1970s, a variety of materials ranging from noble metals to nanostructured materials have been employed as surface enhanced Raman scattering (SERS) substrates. In recent years, 2D inorganic materials have found wide use in the development of SERS-based chemical sensors owing to their unique th
Abstract Functional groups in two‐dimensional (2D) Ti 3 C 2 T x MXene are an important factor influencing electrochemical performance in many applications involving energy storage, electrochemical sensors, and water purification. However, after dimethyl sulfoxide (DMSO) delamination, the effect of surface functionalities in Ti 3 C 2 T x is still unclear and there are no systematic reports on its capacitive behavior. Experiments and theoretical calculations confirm the relationship between differ
The product of the lon gene in Escherichia coli is an ATP-dependent protease, protease La, that also binds strongly to DNA. Addition of double-stranded or single-stranded DNA to the protease in the presence of ATP was found to stimulate the hydrolysis of casein or globin 2- to 7-fold, depending on the DNA concentration. Native DNA from several sources (plasmid pBR322, phage T7, or calf thymus) had similar effects, but after denaturation the DNA was 20-100% more effective than the native form. Al
Abstract Functional materials with attractive electronic and photoelectronic properties show great promise in various fields. In recent decades, tremendous research efforts have been devoted to the design of photoactive and electroactive materials for qualitative and quantitative analysis of environmental pollutants. This review gives a concise overview on the fundamentals and recent research progress of functional material‐based electrochemical and photoelectrochemical technology for environmen
Electrodeposition of high-surface-area nanoporous Au-Cu foams under conditions of hydrogen codeposition is studied. The honeycomb-like Au(x)Cu(100-x) foams with 0 ≤ x ≤ 100 are electrodeposited by controlling the amount of corresponding ions in the solution. The amount of metal ions in deposited films follows that in used electrolytes. Compared to monometallic foams, the Au(x)Cu(100-x) structures are characterized by smaller ligament or particle sizes (less than 10 nm) and improved stability. Th
