This one-day symposium was a pre-event of ICAME 2019, and the organizer was Mössbauer Effect Data Center, Dalian Institute of Chemical Physics, Chinese Academy of Sciences. The organizing committee chairs were Professors Tao Zhang, Junhu Wang and Xiaodong Wang, who were also the chairs of ICAME 2019.

At the request of the International Mössbauer Community, especially Dr. Ercan Alp's proposal, we arranged this special Symposium prior to ICAME 2019. The symposium focused on the latest development of the nuclear resonant scattering techniques as well as their applications at synchrotron radiation (going to ultra-low emittance) and free electron lasers. As an important pre-event of the ICAME 2019 conference, this one-day Symposium mainly covered the following topics:

1. Current status of nuclear resonant scattering techniques at high energy synchrotron facilities

2. Scientific applications in catalysts, biochemistry, high pressure, magnetism, quantum optics, etc.

3. Perspectives of nuclear resonant scattering on the ultra-low emittance synchrotron radiation and free electron lasers

This Symposium aimed to reach out researchers who would like to learn more about a variety of methods and capabilities available, and to give them an opportunity to learn the latest developments of nuclear resonant scattering in terms of methods, instrumentation and science. The coordinators of the symposium were Dr. Wei Xu, Institute of High Energy of Physics, CAS; Prof. Jianfeng Li, University of Chinese Academy of Sciences; Dr. Ercan Alp, APS, Argonne National Laboratory; Prof. Makoto Seto, Kyoto University, Japan; Dr. Satoshi Tsutsui, Japan Syhcnrotron Radiation Research Institute, Spring-8, Japan. We express our heartfelt thanks to the coordinators for their selfless dedication to the success of this symposium.

This one-day symposium was financially supported by “DICP Symposium Special Fund”, and was numbered as the 51st sessions of the DICP symposium.

In the opening ceremony, Professor Junhu Wang, on behalf of the organizing committee, gave a welcome speech and brief introduction to the background and purpose of the one day symposium. Professor Ralf Röhlsberger, on behalf of IBAME, International Board on the Applications of the Mössbauer Effect, Dr. Ercan Alp, founder-member of this one-day symposium, Senior Scientist of Argonne National Laboratory, United States, both of them also gave speeches.

A total hundreds of scholars from more than 20 countries and regions participated in the one-day symposium. The one-day symposium totally arranged 15 invited lectures (30-minute each including discussion), focusing on the latest development of nuclear resonance scattering technology and its applications related to synchrotron radiation and free electron lasers. The one-day symposium started from the opening ceremony at 08:30AM on the first floor meeting room of the DICP's Energy Fundamentals Building, ended from a buffet dinner with Spanish wine at the DICP's cafeteria A at about 09:30PM.

This one-day symposium is the second nuclear resonance scattering related event organized in China. The first nuclear resonance scattering workshop was organized by Institute of High Energy Physics, Chinese Academy of Sciences in Beijing on 19-21 January, 2017. In China, nuclear resonance scattering related international event is held to provide learning and communication opportunities for scientific and technical workers in the relevant fields, and is important to open the new research field on the application of nuclear resonance scattering technology in China. The details of one-day symposium are listed in the attached Table.
