At the XXV Congress and General Assembly of the International Union of Crystallography in Prague, it was decided that the 35th edition of the European Crystallographic Meeting would be held in Lviv, Ukraine, in 2025.

 Unfortunately, there is a war in Ukraine, and it is not reasonable to organize a great scientific event in Lviv in 2025. An alternative was thus elaborated where, thanks to a collaboration between the Ukrainian Crystallographic Committee and the Polish Crystallographic Association, the conference site will be Poznan, a city in neighbouring Poland.

Accurately matching an experimental powder X-ray pattern to a crystal structure is essential for identifying materials, especially for polymorphs in complex landscapes. The CSD-Materials suite now includes a CSD Python API feature based on the FIDEL method, known as AutoFIDEL, which allows for matching and optimizing crystal structures against experimental powder diffraction patterns, without requiring high-resolution transmission data and with preferred orientation.

The FIDEL method can compensate for the preferred orientation frequently seen in powder data. It involves optimising the match between the experimental pattern and the simulated pattern of a selected structure, through varying the structure's lattice parameters. It has proven effective for factors like preferred orientation and sample height displacement.

During this webinar, we will show:

• What is AutoFIDEL and how to access it;

• The process of powder matching and optimization of crystal structures;

• Live demonstration of the process.

Who should attend:

• Solid-state computational chemists

• Data scientists working with chemical data.

• Solid form scientists in academia or industry.

• Cheminformaticians.

The ACA Summer Course in Chemical Crystallography is a program that is now into its third decade of instruction here in the United States. The current incarnation of the course is directed towards Single-Crystal Chemical Crystallography and Powder Diffraction techniques, as applicable to small molecule studies. The course is designed to instruct attendees in the theory and practice of these two aspects of crystallography.

The course is held every summer, in even years now at Purdue University, and in odd years at Northwestern University. For updates on the course, click here.

No prior knowledge of crystallography is expected from attendees. However, a good understanding of undergraduate level chemistry, physics and mathematics is desirable. While the course is geared towards graduate level attendees, applications from strong undergraduate students will be considered. Â Past course attendees have included faculty members and industrial researchers.

The EPDIC Conference is the biennial meeting dedicated to all aspects of the analysis of polycrystalline materials by diffraction methods. It brings together experts from universities, research institutes and instrumentation companies to share their knowledge and discuss the current trends and challenges in powder diffraction.
In agreement with the traditional character of this Conference, EPDIC18 will yield an exciting scientific program that will cover a broad range of hot traditional and new topics interesting to the powder community.

The Conference will be held in Padova, at the Padova Congress Centre on behalf of AIC. It will be organized in synergy with ECM34, which will precede EPDIC18 in the same location.
