Studies of the regioselective ring-opening closing mode of functionally different thiazolidine type enaminones: en route to the synthesis of trithiaazapentalene derivatives
(Oxford : Pergamon-Elsevier Science Ltd, 2013)
Trithiaazapentalene derivatives were prepared by the reaction of 2-alkylidene-4-oxothiazolidines with Lawesson's reagent. They are classified as two structurally different trithiaazapentalene compounds that have different ...
Characterization and methanol electrooxidation studies of Pt(111)/Os surfaces prepared by spontaneous deposition
(American Chemical Society (ACS), 2006)
Catalytic activity of the Pt(111)/Os surface toward methanol electrooxidation was optimized by exploring a wide range of Os coverage. Various methods of surface analyses were used, including electroanalytical, STM, and XPS ...
Assessment of heavy metal pollutants accumulation in the Tisza river sediments
(Academic Press Ltd- Elsevier Science Ltd, London, 2009)
In this study we have worked on the evaluation of heavy metal contamination in the sediments taken from the Tisza River and its tributaries, and thereby used the sequential extraction method, geochemical normalization, the ...
Segregation in water fluidized beds of sand particles
(Elsevier Science Sa, Lausanne, 2013)
Fluidization experiments were conducted on four fractions of filtration (quartz) sand using columns of 144 and 64 mm i.d. The size distribution of the fractions obtained by sieving followed an approximately modified normal ...
Methanol oxidation on Ru/Pd(poly) in alkaline solution
(Elsevier, 2018)
Polycrystalline Pd electrode, Pd(poly), is modified by Ru nanoislands using spontaneous deposition method. Coverage of Pd(poly) electrode with the deposited Ru are approx. 20, 30 and 50% as estimated from phase atomic force ...
Novel WO3/Fe3O4 magnetic photocatalysts: Preparation, characterization and thiacloprid photodegradation
(Korean Society of Industrial Engineering Chemistry, 2019)
This work presents the characterization of novel synthesized WO3/Fe3O4 catalysts and investigates their photocatalytic activity for thiacloprid decomposition under UV and simulated sunlight radiation. Four WO3/Fe3O4 ...
Process modelling and analysis of plasma electrolytic oxidation of titanium for TiO2/WO3 thin film photocatalysts by response surface methodology
(Elsevier, 2015)
Plasma electrolytic oxidation of titanium in 12-tungstosilicic acid solution was investigated as a model reaction. The influence of the process parameters (concentration of 12-tungstosilicic acid solution, current density, ...
Mathematical modeling of the hypothalamic–pituitary–adrenal system activity
(Elsevier, 2005)
Mathematical modeling has proven to be valuable in understanding of the complex biological systems dynamics. In the present report we have developed an initial model of the hypothalamic-pituitary-adrenal system self-regulatory ...
Synthesis, cytotoxic activity and DNA-interaction studies of novel anthraquinone-thiosemicarbazones with tautomerizable methylene group
(Elsevier France-Editions Scientifiques Medicales Elsevier, Paris, 2013)
A series of novel anthraquinone thiosemicarbazone derivatives in a tautomerizable keto-imine form was synthesized and tested for their in vitro cytotoxic activity against human cancer cells (HeLa, MDA-MB-361, MDA-MB-453, ...
Crystallographic and ab initio study of pyridine CH-O interactions: linearity of the interactions and influence of pyridine classical hydrogen bonds
(Royal Soc Chemistry, Cambridge, 2013)
The CH-O interactions of pyridine with water molecules were studied by analysing the data in the Cambridge Structural Database (CSD) and by ab initio calculations. The analysis of the CH-O interactions in the crystal ...
