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 1–5, 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!

On behalf of the Conference Committee, we are delighted to invite you to 82nd annual Pittsburgh Diffraction Conference (PDC). This year’s conference will be held October 9–12, 2025 at Brookhaven National Laboratory, on New York’s beautiful Long Island.
 

The Pittsburgh Diffraction Conference is one of the longest-running scientific meetings in North America focused on the advancement of structural science through diffraction-based methods. Bridging both life sciences and materials sciences, the conference brings together researchers who utilize laboratory-based instruments, X-ray light sources, electron diffraction, and neutron scattering to explore the structure and dynamics of matter. It serves as a vibrant forum for sharing recent scientific breakthroughs, fostering interdisciplinary collaborations, and highlighting innovations across experimental and computational frontiers

This year’s program features a diverse and timely selection of breakout sessions, reflecting key areas of growth in the field. Topics include energy storage, emphasizing structural insights that enable next-generation energy technologies; AI and its applications in the development of emergent materials; novel materials with transformative properties; and the effects of extreme environments on structures, reveling details on dynamic processes and molecular motion that lead to biomolecular functions and a better understanding of complex soft materials.
