On behalf of the Asian Crystallographic Association (AsCA), the Local Organizing Committee (LOC), and the International Program Committee (IPC), we are pleased to announce the 19th Conference of AsCA (AsCA 2025) in Taipei, Taiwan, co-hosted by Taiwan and Japan. The conference will take place at the Taipei International Conference Center (TICC) on December 1â€"5, 2025, jointly with the Symposium on Crystallography of Taiwan and the Crystallographic Society of Japan (CrSJ) Meeting.

AsCA, a regional associate of the International Union of Crystallography (IUCr), is the largest association in the field of structural science within the Asia-Oceania region. This conference, held when there is no IUCr congress, gathers participants not only from Asia and Oceania but also from other regions to share the latest research and advancements. It serves as a valuable platform for exchanging knowledge and strengthening international crystallographic networks among global researchers.

The LOC, formed by the Taiwan and Japan crystallographic societies, and the IPC, composed of international representatives of six major area including biology, physics, chemistry, materials science, and database/data science, are arranging a rich program featuring plenary lectures, keynotes, invited talks, oral and poster presentations, and microsymposia on hot-topic subjects. Additionally, there will be multiple workshops in Taiwan and Japan, commercial exhibitions, council meetings, local association meetings, a half-day synchrotron tour at NSRRC, and social events, including a welcome reception, a young scientist mixer, and a conference dinner.

Taiwan is renowned for its safety, vibrant high-tech industry, diverse cuisine, and natural beauty. Taipei, with its blend of tradition and modernity, offers iconic landmarks like Taipei 101 and night markets, all conveniently close to the conference venue TICC, ensuring a memorable experience.

We look forward to welcoming you to AsCA2025!

The ISXB series of symposium aim to bring together researchers from all over the world who are interested in the fascinating phenomenon of halogen bonding and related interactions, from fundamental principles to applied technologies, covering both experimental and theoretical approaches in various areas of research ranging from advanced materials to medicinal chemistry and chemical biology.

The ISXB6 will feature keynote addresses and invited lectures by internationally renowned experts, contributed presentations, posters, and flash communications by young and promising researchers. The Symposium will also provide ample opportunities for networking and socializing in a friendly and stimulating atmosphere.

It will be held in Dubrovnik, Croatia, from October 20-25, 2024. The symposium will take place at the Sheraton Dubrovnik Riviera Hotel, a modern resort located in a secluded beachfront location in the vicinity of the Dubrovnik Old Town.

LACA is a young scientific association that nucleates a very diverse community studying structural sciences in Latin America. The LACA meeting was previously held in Brazil (2015), Mexico (2016), Chile (2018), Colombia (2019) and Costa Rica (2022) after its foundation in Argentina (2013).

The Committees are working on putting together an exciting program that will allow discussions on the latest developments in structural sciences in the continent and some dedicated talks on what is coming in the field in the near future.

The International Workshop on Improving Data Quality and Quantity in XAFS Spectroscopy (Q2XAFS2023) will be held at the Australian Synchrotron in Melbourne (Australia), August 17-19, 2023. This is a Satellite Meeting of the IUCr Congress. The workshop aims to bring together experts in the field of X-ray Absorption Spectroscopy to discuss aspects of the technique that affect data quality in XAFS experiments.

Q2XAFS2023 will provide a forum for discussions with the goal of reviewing international standards and protocols and developing revised recommendations for best practice when performing XAFS experiments. The workshop will be attended by scientists working at international facilities as well as academics.

The event aims to cover the following elements:

• Portability of XAFS data and scientific content between beamlines and facilities (e.g. data formats, traceability and data provenance)
• Data repositories and access to data
• Precision and reproducibility of data and data treatment
• XAFS data and analyses for industry (e.g. standards, quality control)
• New analytical methods
