Preparation of cellulosic fibers with biological activity by immobilization of trypsin on periodate oxidized viscose fibers
(Springer, Dordrecht, 2014)
In this study, a biologically active fibrous material was designed by immobilizing trypsin on viscose fibers. The viscose yarn was first oxidized with sodium periodate to produce aldehyde groups and then employed as a ...
A generic concept to overcome bandgap limitations for designing highly efficient multi-junction photovoltaic cells
(Nature Publishing Group, London, 2015)
The multi-junction concept is the most relevant approach to overcome the Shockley-Queisser limit for single-junction photovoltaic cells. The record efficiencies of several types of solar technologies are held by series-connected ...
Pyrohydrolytic determination of fluorine in coal: A chemometric approach
(Elsevier, 2010)
Corrosion effects in thermal power plants and environmental impact cause an increase in demand for fluorine analysis in coal. Solid sample decomposition, organic and inorganic fluorine compounds, volatility of fluorine ...
In situ chitosan gelation initiated by atmospheric plasma treatment
(Elsevier Ltd., 2014)
This work reports on the feasibility of atmospheric dielectric barrier discharge (DBD) plasma as a novel synthetic pathway for the liquid phase gelation of chitosan. The DBD plasma chitosan gelation process did not ...
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 ...
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. ...
Influence of the alkali treatment on the sorption and dielectric properties of woven jute fabric
(Springer, 2019)
Woven jute fabric was treated with sodium hydroxide solution of different concentrations at room temperature, for different periods of time. After that, jute fabrics with gradually decreased content of hemicelluloses were ...
Pharmacokinetics and toxicity predictors of new s-triazines, herbicide candidates, in correlation with chromatogrpahic retention constants
(American Chemical Society, 2014)
Herbicides, which are ubiquitously present in soil and food, have been proven to cause human health hazard effects, hence development of new herbicide-active compounds is recommended. In this paper, nine 2,4-bis(cycloalk ...
In situ photoreduction of Ag+-ions on the surface of titania nanotubes deposited on cotton and cotton/PET fabrics
(Springer, Dordrecht, 2017)
This study discusses the possibility of in situ photoreduction of Ag+-ions on the surface of titania nanotubes (TNTs) deposited on the cotton and cotton/PET fabrics in the presence of amino acid alanine and methyl alcohol. ...
