Crystals under Study The Chemical Crystallography Laboratory was open for visitors under the event of Researcher’s Night organised at 27.09.2019. Salt crystals of different origin and colouring components together with flower leafs and stamens could be look under the optical microscope. Visitors could also get to know the X-ray diffraction technique and take a closer look at the instrument.

1st International Alajos Kálmán Prize, Vienna, 21st August 2019
The International Alajos Kálmán Prize is awarded to an individual researcher, in recognition for outstanding scientific contributions, in the field of structural sciences, within the last 5-10 years. The Prize was established by the Hungarian Chemical Society, and is endorsed by the European Crystallographic Association. It is awarded twice, in a three-year cycle, at the ECMs. The selection of the awardee is conducted by ECA SIG13, although the recognised field is wider, including all structural sciences. The prize consists of Read More …
Impact of copper and iron binding properties on the anticancer activity of 8-hydroxyquinoline derived Mannich bases
Veronika F. S. Pape, Nóra V. May, G. Tamás Gál, István Szatmári, Flóra Szeri, Ferenc Fülöp, Gergely Szakács* and Éva A. Enyedy* Dalton Trans., 2018, 47, 17032–17045 Abstract The anticancer activity of 8-hydroxyquinolines relies on complex formation with redox active copper and iron ions. Here we employ UV-visible spectrophotometry and EPR spectroscopy to compare proton dissociation and complex formation processes of the reference compound 8-hydroxyquinoline (Q-1) and three related Mannich bases to reveal possible correlations with biological activity. The studied Read More …
Our group was awarded an International Excellence (KH) OTKA grant
The Chemical Crystallography Group was awarded an International Excellence (KH) OTKA grant: “Research team with significant achievements of internationally outstanding impact “. Title: Supramolecular chemistry in solid state Principal Investigator: Petra Bombicz Participants: Nóra Veronika May Laura Nagyné Bereczki Roberta Palkó Tamás Holczbauer Abstract: Supramolecular chemistry is a highly interdisciplinary field of science covering chemical, physical and biological features. The supramolecular interactions are responsible for the self-assembly of molecules in liquid and solid states. Study of non-covalent interactions is crucial Read More …
Tamás Holczbauer has received a postdoctoral (PD) OTKA grant
Title: Supramolecular interactions and polymorphy, effect of temperature and pressure Abstract: Most of the appliances we use in everyday life are made of solid state materials for example drug, dye or casual objects. The function and lifetime of these objects are important. The understanding and the manipulation of secondary interactions in solid state may provide longer lifetime, different functions, new application for the objects. For example a new polymorph of a known drug may be more advantageous for human consumption, and less Read More …
