Synergistic anti-biofouling effect of Ag-exchanged zeolite and D-Tyrosine on PVC composite against the clinical isolate of Acinetobacter baumannii
(Taylor & Francis Ltd, Abingdon, 2014)
Due to their susceptibility to bacterial biofilm formation, commercial tubes for medical use are one of the main sources of hospital infections with Acinetobacter baumannii. The anti-biofouling activity of novel composites ...
Synthesis, antimicrobial and antioxidative activity of some new isatin derivatives
(Srpsko hemijsko društvo, Beograd, 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 ...
Antimicrobial activity and biocompatibility of Ag--(+) and Cu2+ -doped biphasic hydroxyapatite/alpha-tricalcium phosphate obtained from hydrothermally synthesized Ag+- and Cu2+ -doped hydroxyapatite
(Elsevier Science Bv, Amsterdam, 2014)
Hydroxyapatite (HAp) powders doped with Ag+ or Cu2+ were synthesized by a hydrothermal method in order to obtain biomaterial with an antimicrobial effect. The synthesis was performed with two contents of dopant (Ag+ or ...
Structural, spectral and thermal properties of 2-(2-pyridylamino)pyridinium trihydrogen pyromellitate / Структурна, спектрална и термичка својства 2-(2-пиридиламино)пиридиниjум-трихидрогенпиромелитата
(Srpsko hemijsko društvo, 2014)
The title compound, (Hdipya)(H(3)pyr), where Hdipya is protonated 2,2'-dipyridilamine and H(3)pyr is the monoanion of pyromellitic acid (H(4)pyr), was obtained from a reaction mixture containing Zn(II) ions, dipya, Na(4)pyr ...
Visible light-harvesting of TiO2 nanotubes array by pulsed laser deposited CdS
(Elsevier Science Bv, Amsterdam, 2014)
Titanium dioxide (TiO2) nanotubes arrays, obtained by anodization technique and annealing, were decorated with CdS using pulsed laser deposition method. Their structural, morphological and chemical characterization was ...
Synthesis of α-Al2O3 based foams with improved properties as catalyst carriers
(Institute of Metals and Technology, 2014)
This paper explores the possibility of synthesising catalyst supports with improved properties. Alumina foams were produced with the polymer replication technique. Representative high- and low-temperature sintering ceramics ...
CFD analysis of the influence of centrifugal separator geometry modification on the pulverized coal distribution at the burners
(Transactions of Famena, 2014)
This paper presents the results of 3D numerical flow simulation in the ventilation mill (VM) and air mixture channel (AMC) of Kostolac B power plant, where a centrifugal separator with adjustable blade angle is used. ...
Stimuli-Sensitive Hydrogel Based on N-Isopropylacrylamide and Itaconic Acid for Entrapment and Controlled Release of Candida rugosa Lipase under Mild Conditions
(Hindawi Ltd, London, 2014)
Stimuli responsive pH- and temperature-sensitive hydrogel drug delivery systems, as those based on N-isopropylacrylamide (NiPAAm) and itaconic acid (IA), have been attracting much of the attention of the scientific community ...
Modeling of the Mechanical Behavior of Fiber-Reinforced Ceramic Composites Using Finite Element Method (FEM)
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2014)
Modeling of the mechanical behavior of fiber-reinforced ceramic matrix composites (CMC) is presented by the example of Al2O3 fibers in an alumina based matrix. The starting point of the modeling is a substructure (elementary ...
Influence of amine activators and reaction parameters on grafting reaction between polystyrene and starch
(Springer, Dordrecht, 2014)
Polystyrene graft corn starch copolymers (PS-g-starch) were synthesized by emulsion polymerization using sodium dodecylsulfate (SDS) as the emulsifier and potassium persulfate (PPS) as the initiator. Influences of temperature ...
