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 ...
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 ...
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 ...
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 ...
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 ...
Molecular weight distribution and functional group profiles of TEMPO-oxidized lyocell fibers
(Elsevier Sci Ltd, Oxford, 2013)
The effects of TEMPO-mediated oxidation, performed with NaClO, a catalytic amount of NaBr, and 2,2',6,6'-tetramethylpiperidine-1-oxy radical (TEMPO), were studied on lyocell fibers by means of GPC using multiple detection ...
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 ...
Arsenate adsorption on waste eggshell modified by goethite, alpha-MnO2 and goethite/alpha-MnO2
(Elsevier Science Sa, Lausanne, 2014)
An efficient adsorbents for arsenate removal was developed by modification of calcined eggshell with goethite (calcined eggshell/goethite; sorbent 1), alpha-MnO2 (calcined eggshell/alpha-MnO2; sorbent 2) and hybride system ...
Simultaneous selenium and sulfur speciation analysis in cultivated Pleurotus pulmonarius mushroom
(Elsevier Sci Ltd, Oxford, 2019)
Selenium (Se) and sulfur (S) speciation analysis in edible and medicinal Se enriched P. pulmonarius extracts was performed. Mycelium, colonized substrate, and fruiting bodies at different harvesting times were analyzed ...
