  - Year 2005

  Na podstawie widm 15N NMR przeanalizowano wpływy podstawników wybranych kwasów tiohydroksamowych na przesunięcia chemiczne N-15. Analiza porównawcza z przesunięciami chemicznymi strukturalnie podobnych amidów, tioamidów i kwasów hydroksamowych pozwoliła na stwierdzenie, że nie zatłoczenie steryczne a grupa N-OH jest odpowiedzialna za osłabienie efektów odsłaniających zarówno podstawników bezpośrednio związanych z atomem azotu jak...

  Ścieki powstające podczas procesu remediacji gruntu zawierają surfaktanty o wysokim stężeniu oraz oleje w postaci zemulgowanej i zsolubilizowanej lub wolnej. Do oczyszczenia takich ścieków zastosowano chemiczne utlenianie, biologiczne oczyszczanie oraz zintegrowany proces chemiczno biologiczny. Efektywność procesu oceniono na podstawie redukcji ChZT oraz zmiany stężenia surfaktantu w oczyszczanych ściekach. Chemiczne utlenienie...

• Application of chiral chromatography for enantiomeric separation of currently used pesticides from various chemical groups

  Publication

  • M. Tankiewicz

  - Year 2012

  Chiral pesticides account for more than 25 % of currently used pesticides and this ratio is still increasing. According to the number of chiral centers in the structure, a pesticide may consist of two or multiple enantiomers or stereoisomers. Studies into the stereoselective behaviour of pesticides started in the early 1990s and most research efforts focused on understanding the environmental fate and effects of these pesticides....

  ACCEPTED MAIonic liquids (ILs) have attracted much attention for their unique physicochemical properties, which can be designed as needed by altering the ion combinations. Besides experimental work, numerous computational studies have been concerned with prediction of physical properties of ILs. The results of molecular dynamics simulations of ILs depend strongly on the proper force field parameterization. Classical force fields...

  Our paper presents a qualitative analysis of particular lipid classes (phospholipids, triacylglycerols, cholesterol, free fatty acids) isolated from the tissues of raccoon dogs harvested in northeastern Poland. In all examined tissues (except for the liver) the dominant group of lipids were triacylglycerols. The amounts of lipids representing the other classes depended on the kind of tissue from which the fat was isolated. The...
