Co(III) complexes of (1,3-selenazol-2-yl)hydrazones and their sulphur analogues
(Royal Soc Chemistry, Cambridge, 2017)
The first Co(III) complexes with (1,3-selenazol-2-yl)hydrazones as an unexplored class of ligands were prepared and characterized by NMR spectroscopy and X-ray diffraction analysis. The novel ligands act as NNN tridentate ...
Further sesquiterpene lactones from Anthemis carpatica

Two samples of commercial multi-walled carbon nanotubes (Sigma-Aldrich and Sun Nanotech) and a sample of carbon black (Vulcan XC-72R) were investigated in raw state and after the activation in nitric and sulfuric acid by ...
Novel hexamethylene diamine-functionalized macroporous copolymer for chromium removal from aqueous solutions
(Wiley, Hoboken, 2017)
Macroporous copolymers of poly[(glycidyl methacrylate)-co-(ethylene glycol dimethacrylate)] (PGME) with various crosslinker (ethylene glycol dimethacrylate) concentrations and porosity parameters and additionally functionalized ...
Differences in direct pharmacologic effects and antioxidative properties of mature breast milk and infant formulas
(Elsevier Science Inc, New York, 2013)
Objective: Early-onset and exclusive breast-feeding provides a significant health benefit to infants compared with infant formulas. The aim of this study was to compare mature breast milk with standard infant formulas by ...
The conformation of epinephrine in polar solvents: an NMR study
(Springer/Plenum Publishers, New York, 2018)
Epinephrine (Epi) is a physiologically important catecholamine. Molecular conformation of Epi controls the interactions with other molecules and its biological effects. There have been a number of theoretical studies ...
Quantitative structure-retention relationship of new N-substituted 2-alkylidene-4-oxothiazolidines
(Wiley-Blackwell, Malden, 2011)
A quantitative structure-retention relationship (QSRR) was built to investigate the relationship between the structural descriptors of 23 newly synthesized N-substituted 2-alkylidene-4-oxothiazolidines and their chromatographic ...
