Isostructural zinc and cadmium silanethiolates with bridging biimidazole co-ligands – Enhanced luminescence of zinc complex
PublikacjaTwo dinuclear complexes of zinc and cadmium with silanethiolate and bridging biimidazole ligands are characterized by X-ray diffraction, FT-IR, UV–Vis and emission spectroscopies. The complexes 1 (Zn) and 2 (Cd) are isostructural but exhibit different electronic structures and different character of frontier HOMO orbitals as indicated by DFT calculations. Lluminescence studies prove strong emission properties of zinc complex.

Mobility and biodegradability of an imidazolium based ionic liquid in soil and soil amended with waste sewage sludge
PublikacjaSorption on solids and biodegradation are main phenomena that can mitigate the pollution of soil and water by ionic liquids (ILs). ILs sorbed on soil particles become immobilized (temporarily or permanently) which prevents them from spreading into deeper layers of soil or groundwater but which also makes them less bioavailable. In this study we attempt to examine if amendment of soil with waste sludge has a potential to mitigate...

Structure and evolution of the 4-helix bundle domain of Zuotin, a J-domain protein co-chaperone of Hsp70
PublikacjaThe J-domain protein Zuotin is a multi-domain eukaryotic Hsp70 co-chaperone. Though it is primarily ribosome-associated, positioned at the exit of the 60S subunit tunnel where it promotes folding of nascent polypeptide chains, Zuotin also has off-ribosome functions. Domains of Zuotin needed for 60S association and interaction with Hsp70 are conserved in eukaryotes. However, whether the 4-helix bundle (4HB) domain is conserved remains...

The effect of agro-waste co-digestion and sludge disposal on carbon footprint in municipal wastewater treatment plants
PublikacjaThe study presents analysis of the carbon footprint (CF) in 6 wastewater treatment plants in northern Poland with a special focus on the effect of co digestion of sewage sludge and food waste. Although co-digestion increases the on-site energy production, but it has a negative effect on the total CF. To overcome the negative effect, several sludge disposal scenarios were analysed and their effect on the CF reduction was determined....
