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 ...
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 ...
Chitosan microbeads for encapsulation of thyme (Thymus serpyllum L.) polyphenols
(Elsevier Sci Ltd, Oxford, 2014)
In this work chitosan microbeads were prepared by emulsion technique and loaded with thyme polyphenols by diffusion from an external aqueous solution of Thymus serpyllum L. The effects of concentrations of chitosan (1.5-3% ...
Change in structural, ferroelectric, and magnetic properties of bismuth ferrite induced by doping with gadolinium
(Elsevier Sci Ltd, Oxford, 2019)
Bismuth ferrite, BiFeO3, was doped with a wide range of concentrations (0-30%) of Gd in order to investigate structural, ferroelectric, and magnetic properties and their correlation. Powder samples of Bi1-xGdxFeO3 (x = ...
Carbon materials from waste short hemp fibers as a sorbent for heavy metal ions - Mathematical modeling of sorbent structure and ions transport
(Elsevier Science Sa, Lausanne, 2014)
Carbonized hemp fibers obtained by carbonization of origin and chemically modified waste hemp fibers was used as a low-cost sorbent for heavy metals removal. The efficiency of carbonized hemp fiber samples as a sorbent was ...
Continuous sunflower oil methanolysis over quicklime in a packed-bed tubular reactor
(Elsevier Ltd, 2015)
The continuous sunflower oil methanolysis catalyzed by quicklime in a packed-bed tubular reactor of 60 cm height was studied at 60 °C using methanol-to-oil molar ratios from 6:1 to 18:1 and weight hourly space velocities ...
Towards sustainability of lactic acid and poly-lactic acid polymers production
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
Lactic acid (LA) is a platform chemical which can be produced biotechnologically on agricultural residues, wastes and by-products and further used for production of biodegradable, biocompatible LA polymers. These polymers ...
Nitrogen plasma surface treatment for improving polar ink adhesion on micro/nanofibrillated cellulose films
(Springer, Dordrecht, 2019)
We find that nitrogen plasma treatment of micro/nanofibrillated cellulose films increases wettability of the surface by both liquid polar water and nonpolar hexadecane. The increased wetting effect is more pronounced in ...
Encapsulation of silver nanowire networks by atomic layer deposition for indium-free transparent electrodes
(Elsevier, Amsterdam, 2015)
We report on the development of a novel nano-composite transparent electrode material to be used in various energy applications e.g. as contacts for solar cells, composed of a wet-chemically synthesized silver nanowire ...
