Surface structural heterogeneity of high power plasma-sprayed hydroxyapatite coatings
(Elsevier Science Sa, Lausanne, 2016)
The aim of this work was to examine the dependence of the local surface structure (surface structural heterogeneity) on the local thickness (thickness uniformity) and structure properties along the thickness of hydroxyapatite ...
Purification technologies for crude biodiesel obtained by alkali-catalyzed transesterification
(Pergamon-Elsevier Science Ltd, Oxford, 2014)
For commercial application, the ester product of alkali-catalyzed transesterification of vegetable oil or animal fats should be refined after glycerol separation by settling to fulfill the biodiesel standard specifications. ...
Multifunctional jute fabrics obtained by different chemical modifications
(Springer, 2020)
The aim of the present research is first to reduce the jute fabric non-cellulosic components by using different chemical modifications (i.e. alkali and oxidative) and then to analyze their influence on the jute fabric ...
Role of the bifurcated intramolecular hydrogen bond on the physicochemical profile of the novel azo pyridone dyes
(Elsevier Sci Ltd, Oxford, 2019)
A series of novel 5-(4-substituted phenylazo)-1-carboxymethyl-3-cyano-6-hydroxy-4-methyl-2-pyridones had been synthesized and characterized. The study includes spectral determination of the possible tautomeric forms and ...
Novel resveratrol delivery systems based on alginate-sucrose and alginate-chitosan microbeads containing liposomes
(Elsevier Sci Ltd, Oxford, 2016)
We reported the design of liposome-loaded Ca-alginate microspheres as a drug delivery system for controlled release of resveratrol. The effect of admixed sucrose and chitosan coating was assessed in terms of physicochemical, ...
Silver/poly(vinyl alcohol)/chitosan/graphene hydrogels - Synthesis, biological and physicochemical properties and silver release kinetics
(Elsevier Sci Ltd, Oxford, 2018)
This study presents the synthesis of novel silver/poly(vinyl alcohol)/chitosan/graphene (Ag/PVA/CHI/Gr) nanocomposite hydrogels by in situ electrochemical reduction of silver ions in the hydrogel matrix and their thorough ...
Closing the loop: As(V) adsorption onto goethite impregnated coal-combustion fly ash as integral building materials
(Journal of Cleaner Production, 2021)
Fly and bottom ash(es) are the most abundant generated by-products of coal combustion in thermal power plants. This investigation offers a sustainable solution of a double and circular use of industrial waste material in ...
Influence of Potassium Permanganate Oxidation on Structure and Properties of Cotton
(Taylor & Francis Inc, Philadelphia, 2022)
Cotton yarn was oxidized using the various concentrations and pH of potassium permanganate solutions, in order to investigate the influence of oxidation parameters on chemical, mechanical and sorption properties of cotton. ...
Structural Elucidation of Enzymatically Synthesized Galacto-oligosaccharides Using Ion-Mobility Spectrometry Tandem Mass Spectrometry
(Amer Chemical Soc, Washington, 2016)
Galacto-oligosaccharides (GOS) represent a diverse group of well-characterized prebiotic ingredients derived from lactose in a reaction catalyzed with beta-galactosidases. Enzymatic transgalactosylation results in a mixture ...
The study of thermal behavior of montmorillonite and hydromica brick clays in predicting tunnel kiln firing curve
(Elsevier Sci Ltd, Oxford, 2017)
The aim of this study was to test montmorillonite and hydromica type of brick clays by using simultaneous thermal analysis and dilatometry in an assessment of the suitability of brick clays to produce building elements. ...
