Influence of hemicelluloses and lignin content on structure and sorption properties of flax fibers (Linum usitatissimum L.)
(Springer, Dordrecht, 2018)
In this work, alkali and oxidative treatments were employed to obtain flax fibers with different content of hemicelluloses and lignin, in order to study the influence of chemical composition on structure and sorption ...
The effects of the synthesis parameters on the xerogels structures and on the swelling parameters of the poly(methacrylic acid) hydrogels
(Elsevier Science Sa, Lausanne, 2010)
Poly(methacrylic acid) hydrogels were synthesized. The effects of the synthesis parameters: the neutralization degree of methacrylic acid and the concentrations of monomer, crosslinker and initiator on the xerogels structural ...
Antibacterial activity of heavy metal-loaded natural zeolite
(Elsevier Science Bv, Amsterdam, 2012)
The antibacterial activity of natural zeolitized tuffs containing 2.60 wt.% Cu2+, 1.47 Zn2+ or 0.52 Ni2+ were tested. Antibacterial activities of the zeolites against Escherichia coli and Staphylococcus aureus were tested ...
Silver incorporation on viscose and cotton fibers after air, nitrogen and oxygen DBD plasma pretreatment
(Springer, Dordrecht, 2013)
Dielectric barrier discharge (DBD) pretreatments in air, nitrogen and oxygen plasma of viscose and cotton fabrics with subsequent immobilization of silver were studied. Surface activation of treated fibers was evaluated ...
Study of interaction between nitrogen DBD plasma-treated viscose fibers and divalent ions Ca2+ and Cu2+
(Springer, Dordrecht, 2014)
Viscose fibers were treated with atmospheric pressure dielectric barrier discharge (DBD) plasma obtained in nitrogen in order to activate the fiber surface prior to sorption of the divalent ions Ca2+ and Cu2+. Methylene ...
TEMPO-oxidized cotton as a substrate for trypsin immobilization: impact of functional groups on proteolytic activity and stability
(Springer, Dordrecht, 2017)
Cotton fibers containing different amounts of aldehyde and carboxyl groups were prepared by varying TEMPO oxidation conditions and then employed as carriers for trypsin immobilization. Depending on the functional group ...
New composites based on waste PET and non-metallic fraction from waste printed circuit boards: Mechanical and thermal properties
(Elsevier Sci Ltd, Oxford, 2017)
Influence of the addition of three different non-metallic fractions (NMF), obtained by processing of printed circuit boards (PCBs), on the mechanical and thermal properties of unsaturated polyester resin (UPR) based ...
Nanomechanical and anti-stabbing properties of Kolon fabric composites reinforced with hybrid nanoparticles
(Elsevier Sci Ltd, Oxford, 2017)
In this study carbon nanotubes (CNT) and silica nanoparticles (SiO2) were added to enhance the dynamic mechanical and anti-stabbing properties of the polyurethaneip-aramid multiaxial fabric (Kolon fabric) composites for ...
Absorption boost of TiO2 nanotubes by doping with N and sensitization with CdS quantum dots
(Elsevier Sci Ltd, Oxford, 2017)
A process of obtaining N-doped TiO2 nanotubes sensitized by CdS nanoparticles is presented, including detailed characterizations performed along the synthesis. Transparent TiO2 films consisting of nanotubes, 2.5 mu m long ...
Production of enzymes by a newly isolated Bacillus sp TMF-1 in solid state fermentation on agricultural by-products: The evaluation of substrate pretreatment methods
(Elsevier Sci Ltd, Oxford, 2017)
Study on potential of different agro-industrial waste residues for supporting the growth of newly isolated Bacillus sp. TMF-1 strain under solid-state fermentation (SSF) was conducted aiming to produce several industrially ...
