2019/10/23
The annual NSRRC Users' Meeting and Workshops convened September 17 to 20, 2019. Co-hosted by the UEC Chair, Prof. Hong-Cheu Lin (Natl. Chiao Tung Univ.) and the NSRRC scientist, Dr. Ching-Shun Ku, 498 people attended the meeting, including 62 invited speakers. Besides two workshops, this year’s meeting featured NSRRC Run, and a scientific photography competition to celebrate its 25th anniversary.

The first day began with opening remarks from the UEC Chair, followed by an overview of the Center’s status and prospects by Director Gwo-Huei Luo. Prof. Masaki Takata (Tohoku Univ.) delivered the keynote speech, titled “Building a New Range of 3GeV Facility – Challenge of Super Lightsource for Industry Technology in Japan (SLIT-J) Project.” Later Dr. Ming-Chyuan Lin and Dr. Yu-Shan Huang updated the audience on recent progress within Light Source Division and Experimental Facility Division, respectively, before the Users’ Town Meeting was held.

On the second day, parallel sessions of poster oral presentations preceded after NSRRC Run, including Materials Science, Physics/Chemistry, and Life Sciences. In the afternoon, Distinguished Professor of McMaster Univ., Bruce D. Gaulin was invited to a special session, “Sow-Hsin Chen Neutron Technology and Application Honorary Lecture.” He spoke about his study on “Spin and Charge Correlations in High Tc Superconductors and Related Quantum Magnets.” The scientific program of the day concluded with five breakout interest group meetings covering Protein X-ray Crystallography, Powder X-ray Diffraction, SR-based Microscopy, X-ray Absorption Spectroscopy, and X-ray and Neutron Scattering.

This year the Users’ Meeting lasted for two days so as to highlight more research results from the user community. Over the two days, 12 outstanding users were invited to talk about their latest research; two poster sessions covered 243 presentations, including 148 posters and 9 oral presentations entering competitions. The winners (see the table below) were given awards before the banquet. Prof. Tsan-Yao Chen (Natl. Tsing Hua Univ.) succeeded Prof. Lin as the UEC chair at the banquet which was held in the evening.

Two topic-specific workshops were held during the next two days. Summarized below are these workshops.

Workshop I: Applications of Small- and Wide-Angle X-ray Scattering in Polymer and Biomedical Industries

The angstrom-to-submicron structure of soft matter, protein and its complex can be observed in real time by taking advantages of small- and wide-angle X-ray scattering. This workshop was held on the 19th and was organized by NSRRC scientists Dr. Yen-Chih Huang, Dr. U-Ser Jang, Dr. Orion Shi, and Dr. Wei-Tsung Chuang. It gathered experts from both academia and industries in polymer and biomedical fields, and aimed to discuss the current development, prospects and challenges in industrial applications.

The morning session covered polymer-related topics. Dr. Yen-Cheng Li (Industrial Technology Research Institute) discussed the material properties, and processing condition of polymer processing, that affect the product’s thermal/mechanical properties. Prof. Hsin-Lung Chen (Natl. Tsing Hua Univ.) addressed solutions using small-angle X-ray scattering (SAXS) to resolve structure features of commercially used polymers. Dr. Kuan-Yi Wu (Far Eastern New Century Co.) revealed that molecular structures affect the crystalline modulus of aramid fibers by using in-situ X-ray diffraction. Prof. Chien-Lung Wang (Natl. Chiao Tung Univ.) highlighted several characterization tools at NSRRC and shared his finding of the crystallinity and crystal orientation in thermal conductivity of pyrolytic graphite.

The second session underlined various applications in biomedical industries. Dr. Chung-Hsing Chou (Tri-Service General Hospital) demonstrated how X-ray scattering used for tissue reconstruction in central nervous system. Dr. Julio Lin (Blue Blood Biotech Co.) showed one of the company’s inventions in promoting wound healing. Dr. Po-Yi Huang (Albcura Co.) reported the progress of albumin used for antibody recognition to antigen. Dr. Shu-Yi Lin (Natl. Health Research Institutes) presented a breakthrough in treating bacterial debris.

The last session continued with a demonstration by Dr. Yi-Qi Yeh (NSRRC) that surfactant binding to bovine serum albumin for multistage unfolding was uncovered from a combined analysis of UV-Vis absorption, refractive index and SAXS. Han-Wei Yen (Academia Sinica) highlighted Distributed Cloud Operation System (DiCOS) adopted in BioSAXS facility. Dr. Meng-Chiao Joseph Ho (Academia Sinica) introduced a robust approach incorporating SAXS and molecular simulation to unveil phosphatase and phosphor-protein interface.

Workshop II: Scientific Opportunities of Soft X-ray/VUV Nano-spectroscopy & Nano-imaging at TPS

Held on the 19th and the 20th, Workshop II was organized by NSRRC scientists, Dr. Der-Hsin Wei, Dr. Cheng-Maw Cheng, Dr. Tzu-Hung Chuang, and Dr. Hung-Wei Shiu. It was given emphasis to explore scientific opportunities for soft X-ray/VUV nano-spectroscopy, nano-imaging, nano-focus ARPES of TPS 27A and TPS 39A. Novel and energy materials for modern technology and industrial application often come with a lot smaller dimensions and behave differently after scaling up. The above techniques are aimed to probe their novel properties in the nanometer scale.

The first day began with a talk from Prof. Tzung-Fang Guo (Natl. Cheng Kung Univ.) about using admittance spectroscopy and X-ray photoelectron spectroscopy to probe the interfacial characteristics of MAPbBr3 Perovskite LED. Prof. Jongwoo Lim (Seoul Natl. Univ.) presented an in-situ electrochemical STXM platform and the preparation protocols his team has developed for applying to electrochemical systems. Dr. Takuji Ohigashi (Institute for Molecular Science) gave an update on the status of a scanning transmission X-ray microscopy beamline in UVSOR-III Synchrotron. Prof. Chung-Li Dong (Tamkang Univ.) reviewed some recent studies of the application to energy materials using in-situ/operando synchrotron X-ray spectroscopy.

In the afternoon, Dr. Jose Avila (SOLEIL) gave the first talk and presented the recent NanoARPES results in chemical and electronic imaging of 2D materials. Prof. Jan-Chi Yang (Natl. Cheng Kung Univ.) demonstrated the deterministic switching/modulation of the ferroelectric and (anti)ferromagnetic orders at ambient temperature through laser illumination. Prof. Po-Wen Chiu (Natl. Tsing Hua Univ.) reported an uncommon insight into the optical properties of monolayer WS2 in 2H, 1T, and 1T’ based on his experiment findings. Prof. Wei-Yen Woon (Natl. Central Univ.) spoke on the growth of graphene and other 2D materials through defect engineering in the growth process.

The second day ended at noon. Dr. Satoshi Kera (Institute for Molecular Science) first talk about his study on frontier orbital state for weakly bound molecules on the surface. Dr. Ying-Jiun Chen (Peter Grünberg Institute) discussed the principles and applications of spin-resolving momentum microscopy. Prof. Pin-Jui Hsu (Natl. Tsing Hua Univ.) pointed out the importance of atomic hydrogen in tailoring noncollinear magnetic spin textures. Prof. Chien-Cheng Kuo (Natl. Sun Yat-sen Univ.) spoke about his work in investigating surface and interfacial interactions using spatial-resolved spectroscopies.
