Organic geochemistry of crude oils from the Intisar oil field (East Sirte Basin, Libya)
(Elsevier, 2016)
Four crude oil samples from the oil fields Intisar A, Intisar D and Intisar E (Sirte Basin, Libya) were investigated in order to define depositional environment, lithology, thermal maturity and geologic age of the corresponding ...
Characterization and photocatalytic properties of tungsten doped TiO2 coatings on aluminum obtained by plasma electrolytic oxidation
(Elsevier, 2016)
This paper presents a recent investigation of rapid deposition of TiO2 nanoparticles on aluminum by plasma electrolytic oxidation in Na2SiO3 center dot 5H(2)O water based electrolyte with addition of TiO2 nanoparticles and ...
Spontaneously Deposited Rh on Au(111) Observed by AFM and XPS: Electrocatalysis of Hydrogen Evolution
(Electrochemical Soc Inc, Pennington, 2016)
Rhodium nanoislands were spontaneously deposited on Au(111) up to a full coverage. Obtained Rh/Au(111) bimetallic surface was characterized ex situ by Atomic Force Microscopy imaging and by X-Ray Photoelectron Microscopy, ...
Resolving the origin of the multimode Jahn-Teller effect in metallophthalocyanines
(Royal Soc Chemistry, Cambridge, 2016)
A detailed Density Functional Theory (DFT) analysis was performed in order to study the multimode Jahn-Teller (JT) problem in the electronic ground state of manganese phthalocyanine (MnPc). A comparison with the magnesium ...
Smectite-chitosan-based electrodes in electrochemical detection of phenol and its derivatives
(Elsevier, 2016)
In this paper smectite-chitosan bionanocomposite (SM-C) based on smectite (SM) from Crni Timok (Black Timok) basin, Serbia, was synthesized and characterized using chemical analysis, XRD and FTIR. The SM-C obtained was ...
Selective anticancer activity of hydroxyapatite/chitosan-poly(D,L)-lactide-co-glycolide particles loaded with an androstane-based cancer inhibitor
(Elsevier, 2016)
In an earlier study we demonstrated that hydroxyapatite nanoparticles coated with chitosan-poly(D,L)-lactide-co-glycolide (HAp/Ch-PLGA) target lungs following their intravenous injection into mice. In this study we utilize ...
Prediction of bed expansion of polydisperse quartz sand mixtures fluidized with water
(Elsevier, 2016)
In this paper, the minimum fluidization velocity and bed expansion of polydisperse sand mixtures fluidized with water were investigated. The fluidization experiments were carried out using 19 different fractions of quartz ...
Optimal pixel resolution for sand particles size and shape analysis
(Elsevier, 2016)
In this paper, the influence of different scanning resolutions and the use of image analysis softwares for the image analysis, SigmaScan Pro, Image) and Matlab, on size and shape factors commonly used in particles ...
Study of the Properties of Urethane-Siloxane Copolymers Based on Poly(propylene oxide)-b-poly(dimethylsiloxane)-b-poly(propylene oxide) Soft Segments
(American Chemical Society (ACS), 2016)
Segmented polyurethanes (PURs) were prepared from alpha,omega-dihydroxypoly(propylene oxide)-b-poly-(dimethylsiloxane)-b-poly(propyleneoxide) (PPO-PDMS) as the soft segment and 4,4'-diphenylmethane diisocyanate and ...
Synthesis of nano-crystalline NiFe2O4 powders in subcritical and supercritical ethanol
(Elsevier, 2016)
Nano-crystalline nickel ferrite has a broad range of applications due to its favourable magnetic properties. Those characteristics can be significantly influenced by the synthesis pathway including methods conducted in the ...
