Crystal Growth and Characterization

Making a high quality crystalline sample is a first step to successfully observe novel and exotic properties in various materials including unconventional superconductors and magnets. Our goals are to grow high quality crystalline samples via solid state reaction, flux method, etc., and to characterize the as-grown crystals by XRD, SEM/EDX, etc.

Metal Nanoparticles and Photocatalysis

Metal nanoparticles exhibit fascinating physical and chemical properties and have wide applications in optics, sensing, diagnostics, and catalysis. To have metal nanoparticles with well-controlled sizes, shapes, architectures and compositions is essential for studying their properties and developing their various applications. We are making great effort on the development of effective methods for the synthesis of new metal nanoparticles as well as for improving the quality and scale of different metal nanoparticles. We are also intensively studying the use of their plasmons to drive different chemical reactions.
