Facts and Figures 133 In this informative workshop, the scientific goals and tech- nical designs of the phase III beamlines were presented and discussed. In total, 169 experts and students participated in the workshops and had a vibrant discussion with NSRRC scientists. Workshop II: Synchrotron X-ray Techniques Facilitate Upgrade of Energy Industry Renewable energy is an important topic not only for the present but also for the future. To develop advanced de- vices such as Li-ion batteries, it is essential to understand the behavior of materials inside batteries under operation. Synchrotron X-ray is an effective source to provide the required information. Consequently, the techniques have been used all over the world. To borrow experience from companies overseas to encourage companies in Taiwan to use synchrotron X-ray techniques, a workshop organized by NSRRC scientists Dr. Shi-Wei Chen and Dr. Chih-Wei Hu was thus held on November 12. In the morning session, we invited Dr. Jim Lee (honorary chairman of Taiwan Battery Association) to give a keynote speech. Dr. Lee clearly introduced the policy and strategy of Li-ion batteries in Taiwan. Following, Dr. Shi-Wei Chen (NSRRC) clearly described synchrotron X-ray techniques that can be used for Li-ion batteries. Dr. Chih-Hung Shen (SYNergy ScienTech Corp.) noted the trend of material evolution for the battery used in wearable devices. Dr. Hung-Ming Kang (E-ONE MOLI Energy Corp.) discussed key issues of Li-ion batteries that should be solved. Finally, Prof. Han-Yi Chen of National Tsing Hua University shared the experience how they used synchrotron X-rays to look into batteries. The session in the afternoon started with the speaker Dr. Kun-Sheng Shen of Gogoro Taiwan Limited. It was extreme- ly interesting that Dr. Shen mentioned Gogoro Taiwan Lim- ited using AI machine learning to control eight million bat- teries that circulated in the market. To predict the failure of batteries in advance is quite important for their work. Prof. Fu-Ming Wang of National Taiwan University of Science and Technology threw a clue about the essentiality of synchro- tron X-rays to develop a Li-ion battery with high energy density. Dr. Chung-Chieh Chang (CEO of GUS Technology) introduced the required characteristics of cathodes in a Li- ion battery. Dr. Po-Chin Chen (China Steel Chemical Corp.) gave a talk about graphite anodes that they developed for use in the next-generation Li-ion battery. Dr. Cheng-Zhang Lu (Industrial Technology Research Institute) talked about the analysis of cathode materials using advanced neutron diffraction. Finally, Prof. Tien-Chin Chang (National Taipei University of Technology) introduced the recycle and reuse of Li-ion battery and the trends in the world. This workshop provided a great opportunity for companies in Taiwan to understand synchrotron X-rays and audiences to grab the key issues of the industry. The deep understand- ing about each other let cooperation between the NSRRC and industry become more and more possible. We expect synchrotron X-rays to help companies in Taiwan in many aspects, just like the situation in the world. Workshop III: Applications of Soft X-ray Tomography in Biomedical Sciences Soft X-ray tomography (SXT) is a newly developed tech- nique to image three-dimensional (3D) native cells in biomedical applications. This workshop was organized by Dr. Lee-Jene Lai (NSRRC), and some domestic speakers were invited to present the motivation of applying SXT in their researches. The opening remarks were delivered by Deputy Director of the NSRRC, Dr. Chun-Jung Chen, to introduce the current development and future prospects of the NSRRC in biomedical applications. This workshop covered some topics of damaged organ- elles, nuclear structure, centriole and mitochondria. Dr. Fu-Tong Liu (Academia Sinica) shared his findings about granule-containing vesicles and morphological changes of mitochondria in mast cell degranulation using SXT. He also found galectins accumulated around the damaged organelles, and would study the 3D morphological changes of damaged sub-cellular organelles and the localization of galectins around them by SXT. Two speakers discussed the nuclear structure. Prof. Shun-Fen Tzeng (National Cheng Kung University) reported the role of interleukin-33
