"Data collection strategies using area detectors and determination of absolute structure".

Prof. Peter Müller (MIT Chemistry Department; EUA)

With the advent of area detectors many old concepts, such as moving a reflection into the “diffraction plane” or collecting a “sphere of data”, have become obsolete and it is now possible to start a data collection without knowing orientation matrix or crystal system.  Nevertheless, the data collection strategy still matters, arguably more than ever, and with the wrong strategy a good crystal can still give rise to poor data.  This presentation will introduce the concepts of completeness, Multiplicity of Observations (MoO) and the combination of omega- with phi-scans, as well as equivalent-based scaling.  The importance of data quality and data collection strategy for absolute structure determination will also be mentioned.

"Polymorphism in molecular crystals and pharmaceuticals"
Prof. Joel Bernstein (Professor Emeritus at Ben-Gurion University of the Negev, Israel and Professor of Chemistry at New York University Abu Dhabi; Emirados Árabes Unidos)

Polymorphism--the multiplicity of structures or forms—Applications  in many disciplines. The properties of a substance are determined by its composition and by its structure. The evolution in the last two decades, a sharp rise in the interest in polymorphic systems, as an intrinsically interesting phenomenon, and as an increasingly important component in the development and marketing of a variety of materials based on organic molecule (e.g. pharmaceuticals, dyes and pigments, explosives etc).
