Momentum, heat, and mass transfer analogy for vertical hydraulic transport of inert particles / Analogija prenosa količine kretanja, toplote i mase pri vertikalnom hidrauličkom transportu inertnih čestica
(Association of Chemical Engineers of Serbia, 2014)
Wall-to-bed momentum, heat and mass transfer in the vertical liquid-solids flow, as well as in the single phase flow, were studied. The aim of this investigation was to establish the analogy among those phenomena. Also, ...
Glycidyl methacrylate macroporous copolymer grafted with diethylene triamine as sorbent for Reactive Black 5 / Makroporozni kopolimer na bazi glicidilmetakrilata funkcionalizovan sa dietilentriaminom kao sorbent tekstilne boje Reactive Black 5
(Assoc Chemical Engineers Serbia, Belgrade, 2014)
In this paper, macroporous glycidyl methacrylate and ethylene glycol dimethacrylate copolymer functionalized with diethylene triamine (PGME-deta), was evaluated as Reactive Black 5 (RB5) sorbent. Batch RB5 removal from ...
A novel β-orcinol depsidone of lichen lobaria pulmonaria
(Asian Journal of Chemistry, 2014)
In continuation of our phytochemical survey of Lobaria pulmonaria has led to the identification of deoxystictic acid in this foliose lichen species for the first time. The isolated β-orcinol depsidone showed moderate ...
Development and validation of an LC-MS/MS method with a multiple reactions monitoring mode for the quantification of vanillin and syringaldehyde in plum brandies
(Serbian Chemical Soc, Belgrade, 2014)
An ultra-performance liquid chromatographic triple quadrupole mass spectrometric (UPLC-QqQ-MS/MS) method with a multiple reactions monitoring mode (MRM) was developed and validated for the quantification of vanillin and ...
Diastereoselective addition of alkenylchromium(III) reagents to Garner's aldehyde. The Nozaki-Hiyama-Kishi coupling approach to sphingosines and ceramides
(Serbian Chemical Soc, Belgrade, 2014)
Intermolecular Nozaki-Hiyama-Kishi coupling between alkenylchromium(III) reagents, derived from either (E)-(2-bromoethenyl)benzene or (E)-1-iodo-1-pentadecene, and the conformationally rigid Garner's aldehyde resulted in ...
Structure and magnetic properties of nanocrystalline NiFe2O 4 prepared via precipitation route
(Polish Academy of Sciences, 2014)
Nanocrystalline Ni-ferrite was synthesized by modified precipitation method in which soluble starch is used as dispersing agent and Na2CO 3 as a precipitating agent. NiSO4-6H2O and Fe(NO3)3-9H2O were used as precursors for ...
Chemical Composition of the Essential Oil of Geum rhodopeum

The response of phytoplankton, zooplankton and macrozoobenthos communities to change in the water supply from surface to groundwater in aquaculture ponds
(Edp Sciences S A, Les Ulis Cedex A, 2014)
Investigating forces driving the structure of aquatic communities has long been an important issue in ecology. In the present study, we focused on the effects of changed water supply for aquaculture ponds on phytoplankton, ...
Synthesis, antimicrobial and antioxidative activity of some new isatin derivatives
(Serbian Chemical Society, 2014)
The isatin derivatives, Schiff bases, were synthesized by the reaction of isatin and various substituted primary amines and characterized by several spectroscopic methods. Investigation of the antimicrobial activity of the ...
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 ...
