Rietveld refinement programs based on the Fundamental Parameters Approach (FPA) calculate the peak shape from the configuration of the optical elements in the beam path. In this episode we learn how to create instrument configuration files for custom instrument setups in Profex.

Lesson 8 of the Profex workshop at the Forschungszentrum Jülich, Germany, in March 2024 discusses some common refinement challenges. The first example provides information about how texture / preferred orientation is refined in Profex. The second example demonstrates how to refine anisotropic crystallite sizes. The third example shows how to create electron density maps (difference Fourier maps), and how they can help with structure refinements.

When asking for support, it helps a great deal if the user provides some information about the installation and the refinement project. In this video, I am giving some advise to users contacting Profex support by e-mail.

It is a great pleasure to invite you to Bioceramics 33, the 33rd conference and annual meeting of the International Society for Ceramics in Medicine (ISCM) which will take place from October 17 to 20, 2023 in Solothurn, Switzerland.
Bioceramics 33 will bring together scientists, industry representatives, and clinicians from across the globe to share the latest discoveries on the design, properties, processing, and use of ceramics and glasses in medicine. There will be a wide range of topics including orthopaedic, dental and soft tissue applications.
Located in the heart of Switzerland’s medical device industry, with one of the world’s highest number of MedTech jobs per capita, Solothurn is an ideal place to foster contacts between leading experts in the field. We are particularly excited to host Bioceramics 33 in Solothurn’s Landhaus, a unique historical venue in the picturesque baroque old town, offering accommodation and sightseeing within walking distance and Switzerland’s top tourist destinations easily accessible by public transportation.
We look forward to meeting you in October 2023!
