DESCRIPTION OF THE GROUP

The Faculty Laboratory of Advanced Crystal Engineering named after Jan Czochralski, Faculty of Chemistry, University of Warsaw.

Crystal engineering and physicochemical research on supramolecular chemistry of clathrates and hydrates of gasses and liquids belong to the main scientific issues tackled in the Laboratory. Research on stability of clathrates is performed with DSC apparatus and/or with calorimeter coupled with FTIR and MS. These analyses are complemented with research on nucleation processes, in order to achieve their necessary comprehensiveness. Studies on nucleation and on influences of different compounds on clathrate formation in gasses (especially methane) are conducted with laser particle size analyzer equipped with a unique pressure chamber, which is not commercially available.

Production of clathrates of methane and/or other gasses and liquids in order to study their structure (e.g. with single-crystal X-ray diffraction) is a complex problem. It is possible under laboratory conditions, with the use of in situ crystallization set, which is a digitally controlled instrument, containing IR laser. Currently, there are just over ten laboratories in the world equipped with such sets, with the Laboratory of Advanced Crystal Engineering being the only one in Poland. One of the diffractometers used in the Laboratory is additionally coupled with Raman and NIR spectrometers.

RESEARCH ACTIVITIES

The Faculty Laboratory of Advanced Crystal Engineering named after Jan Czochralski is equipped with i.a. Bruker Venture single-crystal diffractometer with two different radiation sources Mo ST and Cu IμS and furnished with CryoStream PLUS cooler; Raman MonoVista/ SP spectrometer, FT-NIR Nicolet 6700 near infrared spectrometer with in situ probe for analyses of liquids and solids. The laboratory carries out research and development activities at the Faculty of Chemistry of the University of Warsaw, in the field of broadly defined crystal engineering and physicochemistry.Members of the group are open for: the creation of new research possibilities, education of academic staff at the world-class level, didactic activities in the frame of bachelors, masters and doctoral projects. The laboratory provides its services to the scientific community and external contractors. Interested persons should contact Łukasz Dobrzycki Ph.d. (dobrzyc@chem.uw.edu.pl) or professor Michał K. Cyrański (mkc@chem.uw.edu.pl).
