Most of us attended ‘Ogólnopolskie Kolokwium Katalityczne’, conference dedicated to advances in catalysis, held in Cracow. Karol and Piotr delivered a talk on ‘Synthesis and application of ammonium salts based on D-glucose in phase-transfer catalysts’ and ‘Synthesis of levulinic acid esters in the presence of ionic liquids’, while Ania and Natalia presented short talks linked with poster presentations. Our master student Justyna presented a poster.
