Welcome!

We cordially invite you to AUC 2025, the 27th International Analytical Ultracentrifugation Workshop and Symposium, to be held in Beijing, China, on August 24-30, 2025, on campus of the Tsinghua University. Tsinghua University, with over 113 years of academic heritage, embodies a legacy of innovation and unwavering excellence. At Tsinghua, our assembly of innovative minds and visionaries is striving to fulfill the significant needs of the country and actively building a community with a shared future for mankind.

The focus of AUC 2025 is on studies of biological macromolecules, interacting systems, synthetic polymers, nanoparticles, and colloids. Techniques featured include analytical ultracentrifugation (AUC), dynamic and static light scattering (DLS, MALS), small angle X-ray and neutron scattering (SAXS, SANS), microscale thermophoresis (MST), nuclear magnetic resonance (NMR), surface plasma resonance (SPR), field flow fractionation (FFF), mass photometry (MP) and calorimetry (ITC, DSC), and electron microscopy (SEM, TEM, CT) are featured.

AUC 2025 will open with several workshops, which begin on August 25th, and end on Tuesday, August 26th. These workshops will be given by leading experts in their respective fields. On Wednesday, August 27th there will be a social event with a trip to the Great Wall of China, one of the world’s most iconic structures. The symposium will start on the morning of Thursday, August 28th, with our keynote lecture and continue until the afternoon of Friday, August 29th. The symposium will offer two poster sessions, an exhibitor fair, and roundtable discussions. On Saturday, August 30th, a visit to the National Protein Science Facility will be arranged.

Additional details will be posted on this website over the next few months. For now, please mark your calendars for August 2025. We are very excited to welcome the AUC community to China! We look forward to seeing everyone in Beijing next summer!
