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 ...
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 ...
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 ...
Purification technologies for crude biodiesel obtained by alkali-catalyzed transesterification
(Pergamon-Elsevier Science Ltd, Oxford, 2014)
For commercial application, the ester product of alkali-catalyzed transesterification of vegetable oil or animal fats should be refined after glycerol separation by settling to fulfill the biodiesel standard specifications. ...
Ultrasonic assisted arsenate adsorption on solvothermally synthesized calcite modified by goethite, alpha-MnO2 and goethite/alpha-MnO2
(Elsevier, Amsterdam, 2014)
A highly porous calcium carbonate (calcite; sorbent 1) was used as a support for modification with alpha-FeOOH (calcite/goethite; sorbent 2), alpha-MnO2 (calcite/alpha-MnO2; sorbent 3) and alpha-FeOOH/alpha-MnO2 ...
Synergistic anti-biofouling effect of Ag-exchanged zeolite and D-Tyrosine on PVC composite against the clinical isolate of Acinetobacter baumannii
(Taylor & Francis Ltd, Abingdon, 2014)
Due to their susceptibility to bacterial biofilm formation, commercial tubes for medical use are one of the main sources of hospital infections with Acinetobacter baumannii. The anti-biofouling activity of novel composites ...
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 ...
Mathematical modeling of silver release from antimicrobial nanocomposite Ag/alginate microbeads
(Wiley-Blackwell, Hoboken, 2014)
