报告内容:

Tip-enhanced Raman scattering (TERS) has received significant interest as a new nano-vibrational spectroscopy technique, which can be used to obtain site-specific molecular information. TERS instruments have made remarkable progress, and the application of TERS has been expanding to nanomaterials, liquid samples, biological materials, and electrochemistry. Furthermore, molecular structures with imaging can be explored even at sub-nanometer resolution. My talk consists of two parts: basic studies on the reproducibility of TERS and novel applications of TERS. In the former part, I report the basic principle and characterization of TERS In the latter part, we introduce two examples of TERS applications to nanomaterials, epitaxial graphene, and graphene oxide and two examples of liquid TERS that use chemically modified tips: nanoscale pH measurement and enantiomeric discrimination using TERS. Finally, we discuss the perspective of TERS.

报告人简介:

Yusuke Morisawa was born in 1975 in Kyoto, Japan. He obtained his Bachelor's degree in 1998 from Kwansei Gakuin University, followed by Master's (2000) and Doctoral (2005) degrees in Science from Kyoto University. He held the position of Postdoctoral fellow at Kwansei Gakuin University. Subsequently, he served as a Lecturer (2012–2016) and is currently an Associate Professor (2016–) at Kindai University in Osaka, Japan. He received the Japan Society for Analytical Chemistry Award for Advanced Analytical Technology (JAIMA Award) in 2011, the Spectroscopic Society of Japan Award for Young Scientist in 2013, and NIR Advanced award in 2020. His ongoing research focuses on the field of molecular spectroscopy.

报告内容:

FUV spectroscopy constitutes a potent methodology for molecule identification and exploration of intermolecular interactions. Nevertheless, challenges persist in the unambiguous assignment of overlapping bands and the comprehensive investigation of molecular structure and associated interactions. Conversely, while ultraviolet resonance Raman (UVRR) spectra have hitherto served as a valuable tool for protein structural analysis, intriguing prospects lie ahead by extending the excitation wavelength towards shorter wavelengths. By harnessing the complementary nature of FUV and UVRR, novel avenues emerge for the comprehensive examination of the electronic state and structural intricacies of molecules This talk consists of four parts: (1) introduction to FUV spectroscopy, (2) development of FUV spectrometers, (3) study of electronic states using FUV spectroscopy (4) FUV and UVRR study studies of N-acetylamide saccharides.
