Synthesis, particle shape characterization, magnetic properties and surface modification of superparamagnetic iron oxide nanochains
(Materials Characterization, 2019)
We report monodisperse, chain-like particles (nanochains) consisted of silica-coated maghemite (γ-Fe2O3) nanoparticle clusters prepared by colloidal chemistry and magnetic field-induced self-assembly of nanoparticle clusters. ...
Comparative kinetic study of mechanical activation process of mica and talc for industrial application
(Elsevier Sci Ltd, Oxford, 2014)
Mica and talc have wide areas of application as a raw material in a number of industrial branches. Mechanically activated mica has specific applications such as: capacitors, insulators, and pearlescent pigments. Talc is ...
Characterization of sodium alginate/D-limonene emulsions and respective calcium alginate/D-limonene beads produced by electrostatic extrusion
(Elsevier Sci Ltd, Oxford, 2015)
In this study, calcium alginate beads immobilizing D-limonene (solid systems) have been manufactured starting from emulsions of this flavor in sodium alginate (liquid systems). The effects of alginate concentration (0.02 ...
Hydrophobic Coatings on Cotton Obtained by in Situ Plasma Polymerization of a Fluorinated Monomer in Ethanol Solutions
(American Chemical Society, 2017)
Plasma polymerization using hydrophobic monomers in the gas phase is a well-known technology to generate hydrophobic coatings. However, synthesis of functional hydrophobic coatings using plasma technology in liquids has ...
Dislocation glide-controlled room-temperature plasticity in 6H-SiC single crystals
(Elsevier Ltd, 2014)
In situ transmission electron microscopy observations of uniaxial compression of sub-300 nm diameter, cylindrical, single-crystalline 6H-SiC pillars oriented along 〈0001〉 and at 45° with respect to 〈0001〉 reveal that plastic ...
Amine activators influence on grafting reaction between methacrylic acid and starch
(Elsevier Sci Ltd, Oxford, 2012)
The aim of this work was synthesis of grafted copolymers of poly(methacrylic acid) and starch (PMAA-graft-starch) with high percentage of grafting, G (%). The effect of temperature (55-75 degrees C), concentration of ...
Immobilization of dextransucrase on functionalized TiO2 supports
(Elsevier Science Bv, Amsterdam, 2018)
The TiO2 based hybrid supports with different functional groups (amino, glutaraldehyde or epoxy) were prepared and their influence on immobilization of dextransucrase (DS) was studied. Novel synthetic route for surface ...
Surface cleaning of raw cotton fibers with atmospheric pressure air plasma
(Springer, Dordrecht, 2018)
In this work, a possibility to use atmospheric pressure plasma treatment to clean cotton fibers surface was investigated. Dielectric barrier discharge (DBD) operating in air was used as plasma source. After plasma treatment, ...
Adhesion testing of composites based on Bis-GMA/TEGDMA monomers reinforced with alumina based fillers on brass substrate
(Elsevier Sci Ltd, Oxford, 2018)
Quantitative assessment of the adhesion behavior between the composite film having UV cured Bis-GMA (Bisphenol A glycidylmethacrylate)/TEGDMA (triethylene glycol dimethacrylate) as matrix and the aluminum oxide based ...
Sorption and dielectric properties of jute woven fabrics: Effect of chemical composition
(Elsevier B.V., 2019)
The jute woven fabric was treated with sodium hydroxide and sodium chlorite under different conditions in order to study the influence of the chemical composition on their sorption and dielectric properties. After the ...
