The use of biological markers in the determination of the origin and type of organic matter in the sediments of the Tisza River
(Serbian Chemical Soc, Belgrade, 2014)
The objective of this study was to determine the origin and type of organic matter (OM) in recent sediments of the Tisza River, along a distance of 153 km through the territory of Serbia. For this purpose, group ...
Synthesis and spectroscopic properties of large single-crystals of Pb(II), Hg(II) and Sr(II) methanesulfonato 1D coordination polymers
(Oxford : Pergamon-Elsevier Science Ltd, 2014)
Three new 1D coordination polymers, [Pb-2(CH3SO3)(4)(H2O)(2)](n), [Hg(CH3SO3)(2)(H2O)(2)](n) and [Sr(CH3SO3)(2)(H2O)](n), were synthesized as large single crystals. The crystals were analyzed and characterized by the means ...
Morphological and chemical characterization of Arnica montana L. under different cultivation models
(Elsevier, 2014)
Arnica (Arnica montana L) is a perennial mountain plant whose flower heads are mainly used for topical treatment of bruises and sprains in phytopharmaceutical preparations such as ointments, creams and gels. In this study, ...
Preservation of diagenetic products of beta-carotene in sedimentary rocks from the Lopare Basin (Bosnia and Herzegovina)
(Elsevier Gmbh, Urban & Fischer Verlag, Jena, 2014)
Sedimentary rocks from the saline formation of the Lopare Basin were investigated. Sediments contain a moderate amount of immature to marginally mature algal organic matter deposited under slightly reducing to anoxic and ...
Isolation, Characterization, and In Vitro Cytotoxicity of New Sesquiterpenoids from Achillea clavennae
(Georg Thieme Verlag Kg, Stuttgart, 2014)
Further phytochemical investigation of the aerial parts of Achillea clavennae has resulted in the isolation of three new sesquiterpene lactones: two highly oxygenated germacranolides (1, 2) and the iso-seco-guaianolide ...
Structural modifications of 4-aryl-4-oxo-2-aminylbutanamides and their acetyl- and butyrylcholinesterase inhibitory activity. Investigation of AChE-ligand interactions by docking calculations and molecular dynamics simulations
(Elsevier France-Editions Scientifiques Medicales Elsevier, Paris, 2014)
Congeneric set of thirty-eight 4-aryl-4-oxo-2-(N-aryl/cycloalkyl)butanamides has been designed, synthesized and evaluated for acetyl- and butyrylcholinesterase inhibitory activity. Structural variations included cycloalkylamino ...
Plasmonic sensors in multi-analyte environment: Rate constants and transient analysis
(Inst Chemical Engineers, Rugby, 2014)
This paper investigates multicomponent gas adsorption at the active surface of plasmonic chemical sensors and shows that there are situations where transients in a single sensor element can be used for simultaneous detection ...
