Influence of clay organic modifier on the morphology and performance of poly(epsilon-caprolactone)/clay nanocomposites
(Srpsko hemijsko društvo, Beograd, 2015)
Two series of poly(epsilon-caprolactone) poly(oxepan-2-one) nanocomposites with different organo-modified clays (1 to 8 wt. %) were prepared by the solution casting method. Organoclays with polar (Cloisite (R) C30B) and ...
The porosity and roughness of electrodeposited calcium phosphate coatings in simulated body fluid
(Srpsko hemijsko društvo, Beograd, 2015)
Calcium phosphate coatings were electrochemically deposited on titanium from an aqueous solution of Ca(NO3)(2) and NH4H2PO4 at a current density of 10 mA cm(-2) for a deposition time of 15 mm. The obtained brushite coatings ...
Adsorption of Candida rugosa lipase onto alumina: effect of surface charge
(Serbian Chemical Society, 2015)
The impact of the surface charge of alumina supports on the adsorption of Candida rugosa lipase was investigated in terms of the zeta potentials of the adsorption partners. The lipase adhered onto alumina with similar ...
Antibacterial activity of copper-containing clinoptilolite/PVC composites toward clinical isolate of Acinetobacter baumannii
(Srpsko hemijsko društvo, Beograd, 2015)
The multidrug-resistant bacteria Acinetobacter baumannii cause serious hospital infections. Commercial poly(vinyl chloride) (PVC) used for endotracheal tubes was modified in order to obtain a composite with an antibacterial ...
The use in grass production of clinoptilolite as an ammonia adsorbent and a nitrogen carrier
(Srpsko hemijsko društvo, Beograd, 2015)
Clinoptilolite-rich tuff (NZ) from the Zlatokop deposit (Vranjska Banja, Serbia) was studied as a nitrogen carrier for grass production. The mechanism of binding ammonium cations present in aqueous solutions by NZ was ...
Poly(methyl methacrylate) denture base materials modified with ditetrahydrofurfuryl itaconate: Significant applicative properties
(Srpsko hemijsko društvo, Beograd, 2015)
The aim of this work was to examine the possibility of modification of commercial denture base materials with itaconic acid esters, in order to obtain materials with lower toxicity and higher biocompatibility. Despite their ...
Ternary Zn-Ni-Co alloy: anomalous codeposition and corrosion stability
(Srpsko hemijsko društvo, Beograd, 2015)
Electrochemically deposited Zn-Ni-Co alloys under various deposition conditions were investigated using atomic absorption spectroscopy for the determination of the chemical composition, atomic force microscopy for surface ...
Modification of natural clinoptilolite and ZSM-5 with different oxides and a study of the obtained products in lignin pyrolysis
(Srpsko hemijsko društvo, Beograd, 2015)
In this work, different metal oxides (MO) supported on two types of zeolites: 1) natural clinoptilolite (NZ) and 2) synthetic zeolite, ZSM-5 were prepared and tested as catalysts in the fast pyrolysis of hardwood lignin. ...
Sepiolite functionalized with N-[3-(trimethoxysilyl)propyl]ethylenediamine triacetic acid trisodium salt. Part I: Preparation and characterization
(Srpsko hemijsko društvo, Beograd, 2015)
Natural sepiolite from Andrici (Serbia) was functionalized by covalent grafting of N-[3-(trimethoxysilyl)propyl]ethylenediamine triacetic acid trisodium salt onto the Si-OH sepiolite groups. The functionalized material, ...
An apparatus proposed for density measurements in compressed liquid regions at pressures of 0.1-60 MPa and temperatures of 288.15-413.15 K
(Srpsko hemijsko društvo, Beograd, 2015)
In this work, an apparatus for density measurements in the compressed liquid regions is presented. This installation is based on the use of a DMA HP density measuring cell and a DMA 5000 densimeter (both instruments are ...
