Prediction of strong O-H/M hydrogen bonding between water and square-planar Ir and Rh complexes
(Royal Soc Chemistry, Cambridge, 2017)
Intermolecular OH/M interactions, between a water molecule and square-planar acac complexes ([M(acac)L-2]), with different types of L ligands (en, H2O, CO, CN-, and OH-) and different types of metal atoms (Ir(I), Rh(I), ...
Ranking and similarity of conventional, microwave and ultrasound element sequential extraction methods
(Oxford : Pergamon-Elsevier Science Ltd, 2018)
This study aims to compare three extraction techniques of four sequential element extraction steps from soil and sediment samples that were taken from the location of the Pancevo petrochemical industry (Serbia). Elements ...
Brachybacterium sp CH-KOV3 isolated from an oil-polluted environment-a new producer of levan
(Elsevier, 2017)
Various microorganisms isolated from polluted environments, such as Pseudomonas sp. and Micrococcus sp. can synthesize exopolysaccharides (EPSs) which are natural, non-toxic and biodegradable polymers. EPSs play a key role ...
Heracleum orphanidis: chemical characterisation, and comparative evaluation of antioxidant and antimicrobial activities with specific interest in the influence on Pseudomonas aeruginosa PAO1
(Royal Soc Chemistry, Cambridge, 2016)
GC-FID and GC-MS were used to determine the chemical composition of the essential oil of the aerial parts of Heracleum orphanidis Boiss. Also, the HPLC-DAD/ESI-ToF-MS profile of the methanol extracts of aerial parts and ...
Positive and negative nano-electrospray mass spectrometry of ruthenated serum albumin supported by docking studies: an integrated approach towards defining metallodrug binding sites on proteins
(Royal Soc Chemistry, Cambridge, 2018)
Binding of three ruthenium(ii) compounds of general formula mer-[Ru(L3)(N-N)X][Y] (where L3 = 4-chloro-2,2:6,2-terpyridine (Cl-tpy); N-N = 1,2-diaminoethane (en), 1,2-diaminocyclohexane (dach) or 2,2-bipyridine (bipy); X ...
Isolation, characterization and in vitro cytotoxicity of new sesquiterpenoids from Achillea clavennae
(Georg Thieme Verlag, 2014)
Further phytochemical investigation into the aerial parts of Achillea clavennae has resulted in the 3 isolation of three new sesquiterpene lactones: two highly oxygenated germacranolides (1, 2) and 4 the iso-seco-guaianolide, ...
Effect of sepiolite organomodification on the performance of PCL/sepiolite nanocomposites
(Oxford : Pergamon-Elsevier Science Ltd, 2017)
Poly(epsilon-caprolactone) (PCL) based nanocomposites with unmodified and organomodified sepiolites were prepared by solution casting method. The sepiolites were modified with short (3-mercaptopropyl)trimethoxysilane ...
Preferred Geometries and Energies of Sulfur Sulfur Interactions in Crystal Structures
(American Chemical Society (ACS), 2016)
It has been demonstrated that sulfur sulfur interactions can exist in various molecular systems. In this work we investigated sulfur-sulfur interactions in crystal structures of small molecules by analyzing geometric data ...
in/out Isomerism of cyclophanes: a theoretical account of 2,6,15-trithia-[3(4,10)][7]metacyclophane and [3(4,10)][7]metacyclophane as well as their halogen substituted analogues
(Royal Soc Chemistry, Cambridge, 2017)
A detailed theoretical investigation of cyclophanes with a divergent set of methods ranging from molecular mechanics through semiempirical to ab initio is presented. Cyclophanes have attracted interest over the years due ...
Levels of toxic elements in canned fish from the Serbian markets and their health risks assessment
(Academic Press Inc Elsevier Science, San Diego, 2018)
A total of 138 samples of canned tuna, sardines and mackerel from the Serbian market were analyzed for toxic (As, Cd, Pb, Hg) element levels using ICPMS. The highest average contents of toxic elements were found to be 1.70 ...
