Preparation, characterization and photocatalytic activity of lanthanum and vanadium co-doped mesoporous TiO2 for azo-dye degradation
(Elsevier, 2013)
Titanium dioxide photocatalysts co-doped with lanthanum and vanadium were prepared by a facile microwave-assisted hydrothermal method and characterized by XRD, SEM, N-2 physisorption at 77 K and DRS. The characterization ...
Visible light absorption of surface-modified Al2O3 powders: A comparative DFT and experimental study
(Elsevier, 2019)
Surface modification of Al2O3 powders, prepared using reproducible sol-gel synthetic route with small colorless organic molecules, induces charge transfer complex formation and the appearance of absorption in the visible ...
Towards understanding intermolecular interactions in hydantoin derivatives: the case of cycloalkane-5-spirohydantoins tethered with a halogenated benzyl moiety
(Royal Soc Chemistry, Cambridge, 2017)
A series of cycloalkane-5-spirohydantoins bearing a halogeno substituted benzyl group (X = Cl and Br) in position 3 has been synthesized and their structures (1-6) have been determined by a single crystal X-ray diffraction ...
Characterization and electrochemical properties of organomodified and corresponding derived carbonized clay
(Oxford : Pergamon-Elsevier Science Ltd, 2019)
Series of alkylammonium modified smectites with different alkylammoinum/clay ratios was synthesized (H series). The obtained organoclays were used as precursors for carbon-clay composite materials (C series). Both set of ...
Linear modeling of the soil-water partition coefficient normalized to organic carbon content by reversed-phase thin-layer chromatography
(Elsevier, 2016)
Soil-water partition coefficient normalized to the organic carbon.content (K-OC) is one of the crucial properties influencing the fate of organic compounds in the environment. Chromatographic methods are well established ...
Study of heavy metals biosorption on native and alkali-treated apricot shells and its application in wastewater treatment
(Elsevier, 2018)
Locally available apricot (Prunus armeniaca L.) shells classified as a waste product from fruit processing, were alkali activated in order to develop an efficient heavy metal ions sorbent for water purification. To examine ...
5-Aryl-1H-pyrazole-3-carboxylic acids as selective inhibitors of human carbonic anhydrases IX and XII
(Oxford : Pergamon-Elsevier Science Ltd, 2015)
Inhibitory activity of a congeneric set of 23 phenyl-substituted 5-phenyl-pyrazole-3-carboxylic acids toward human carbonic anhydrase (hCA, EC 4.2.1.1) isoforms I, II, IX and XII was evaluated by a stopped-flow CO2 hydrase ...
Fast profiling of protease specificity reveals similar substrate specificities for cathepsins K, L and S
(Wiley-Blackwell, Hoboken, 2015)
Proteases are important effectors of numerous physiological and pathological processes. Reliable determination of a protease's specificity is crucial to understand protease function and to develop activity-based probes and ...
Day of the week effect in paper submission/acceptance/rejection to/in/by peer review journals. II. An ARCH econometric-like modeling
(Elsevier, 2017)
This paper aims at providing a statistical model for the preferred behavior of authors submitting a paper to a scientific journal. The electronic submission of (about 600) papers to the Journal of the Serbian Chemical ...
Analogy between momentum and heat transfer in liquid-solid fluidized beds
(Elsevier, 2015)
Wall-to-bed heat transfer in particulate fluidized beds of spherical particles was studied. Experiments were performed using spherical glass particles of 0.80-2.98 mm in diameter with water in a 25.4 mm I.D. copper tube ...
