Acid-catalysed synthesis of oxathiolone fused chalkones. Comparison of their activity toward various microrganisms and human cancer lines
PublicationOtrzymano podstawione pochodne oksationolowych sprzężonych chalkonów w wyniku kondensacji 4-acetylo-5-metoksy-2-0ksobenz[1,3]oksatiolu z aldehydem benzoesowym w środowisku kwaśnym. Badano właściwości biologiczne otrzymanych związków. Trzy z otrzymanych pochodnych wykazały umiarkowaną aktywność wobec komórek HeLa, dwa były aktywne wobec Micrococcus luteus i Staphylococcus aureus, a jeden wobec Mycobacterium tuberculosis.

Diphosphination of CO2 and CS2 mediated by frustrated Lewis pairs - catalytic route to phosphanyl derivatives of formic and dithioformic acid
PublicationThe first example of CO2 diphosphination is described. Reactions of unsymmetrical diphosphanes with CE2 (E = O, S) catalyzed by BPh3 insert a CE2 molecule into the P-P bond with formation of the products of the general formula R2P-E-C(=E)-PR2. The obtained CO2 adducts arise from synergistic interaction of diphosphane and borane with CO2 molecule.

Development and validation of a method for the simultaneous analysis of fatty acid ethyl esters, ethyl sulfate and ethyl glucuronide in neonatal meconium: application in two cases of alcohol consumption during pregnancy
PublicationAlcohol consumption during pregnancy constitutes one of the leading preventable causes of birth defects and neurodevelopmental disorders in the exposed children. Fatty acid ethyl esters (FAEEs), ethyl glucuronide (EtG) and ethyl sulfate (EtS) have been studied as potential biomarkers of alcohol consumption. However, most analytical approaches proposed for their analysis in meconium samples consist of separated extraction procedures...

The effect of full-cell impregnation of pine wood (Pinus Sylvestris L.) on the fine dust content during sawing on a frame sawing machine
PublicationIn this paper the results of the analysis of the effect of the impregnation treatment of pine wood on the granularity of sawdust from the sawing process on the frame sawing machine PRW 15M are presented. Granulometric analyses of chips from impregnated and unimpregnated pine wood implies that the impregnation of pine wood does not affect the size and structure of the sawdust produced. A major ≈ 95% share of the formed chips is...
