From October 17 to 20, 2025, the 10th Academic Annual Conference and the 8th National Member Representative Conference of the Chinese Crystallographic Society were successfully held in Guilin, Guangxi Province. In the “PDF and Neutron Scattering Technology and Application” session, scholars from multiple universities and research institutions engaged in in-depth discussions on frontier technologies in PDF and neutron scattering, with a concentrated presentation of innovative research outcomes.

In this conference, Prof. Long Yang was elected as a council member of the CCrS. Our group members actively participated in the PDF session, presenting their latest research work. Changyuan Li delivered an oral presentation titled “Local Atomic Structure and Low Lattice Thermal Conductivity in I-V-VI₂ Solid Solutions”, which elucidated the intrinsic relationship between solid solution structures and their thermal transport properties from an atomic-scale perspective, providing insights into fine-tuning lattice thermal conductivities. Yueyue Cheng presented a poster entitled “Elastic Tensor Measurement Method Based on X-ray Single Crystal Diffuse Scattering Experiments”, showing a novel experimental strategy for accurate determination of crystal elastic tensors. This work received the Outstanding Poster Award.

This conference addressed multiple dimensions including methodology development, experimental techniques, and artificial intelligence applications, reflecting the multidisciplinary and integrated evolution of crystallography. Our group members not only demonstrated solid expertise in methodological development, but also provided technical approaches and case studies for interdisciplinary innovation in related fields.

2025年中国晶体学会第十届学术年会

2025年10月17日至20日，中国晶体学会第十届学术年会暨第八次全国会员代表大会在广西桂林成功举办。 在”PDF-中子散射技术与应用”分会场中，来自多所高校与研究机构的学者围绕PDF与中子散射前沿技术展开深入交流，多项创新成果集中呈现。

在此次大会上，杨龙教授当选为新一届中国晶体学会理事。 我们团队多位成员在PDF分会场上展示了多项研究成果。 比如李昌源以《I-V-VI₂族固溶体的局域原子结构及其低晶格热导率》为题作口头报告，从原子尺度揭示了固溶体结构与热输运性能之间的关联机制， 为热导率的精确调控提供了理论依据。程悦悦通过海报《基于X射线单晶漫散射实验的弹性张量测量方法》，展示了一种精确测量晶体弹性张量的实验新策略，并获得大会优秀墙报奖。

本次晶体学年会聚焦方法学、实验技术与人工智能等多个维度，展现了晶体学领域多元融合的发展态势。 我们课题组成员不仅展现了在方法学领域的扎实积累，也为相关领域的交叉创新提供了技术路径与案例参考。
