The effect of annealing temperatures on magnetic and electric properties of electrodeposited Ni85,3Fe10,6W1,4Cu2,2 alloy
(Natl Inst Optoelectronics, Bucharest-Magurele, 2014)
Ni-85,Ni-8 Fe-10,Fe-6 W-1,W-4 Cu-2,Cu-2 alloy powder consisting of an amorphous matrix and nanocrystals of an FCC solid solution of Fe, W and Cu in nickel was produced by electrodeposition. Heating the pressed powder sample ...
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 ...
Electrospun Poly(vinylbutyral)/silica Composite Fibres for Impregnation of Aramid Fabrics
(Materiale Plastice, 2014)
The poly (vinyl butyral)/silica (PVB/SiO2) composite fibers were produced by the electrospinning process. The experiments were performed with the PVB solution in concentration of 10 wt.% where ethanol was used as the ...
Recycling of silver-plated brass for production of high purity copper and ultrafine silver powder for electric contacts
(Bulgarian Chemical Communications, 2014)
The paper presents an improved process for recycling of silver-plate brass housing. Silver and copper are recovered with a purity of 99.99 % and 99.90 %, respectively, with the aim of obtaining materials of higher value ...
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. ...
Influences of synthesis methods and modifier addition on the properties of Ni-based catalysts supported on reticulated ceramic foams
(Springer, New York, 2014)
A method of synthesizing Ni-based catalysts supported on alpha-Al2O3-based foams was developed. The foams were impregnated with aqueous solutions of metal chlorides under an air atmosphere using an aerosol route. Separate ...
Antimicrobial activity and biocompatibility of Ag--(+) and Cu2+ -doped biphasic hydroxyapatite/alpha-tricalcium phosphate obtained from hydrothermally synthesized Ag+- and Cu2+ -doped hydroxyapatite
(Elsevier Science Bv, Amsterdam, 2014)
Hydroxyapatite (HAp) powders doped with Ag+ or Cu2+ were synthesized by a hydrothermal method in order to obtain biomaterial with an antimicrobial effect. The synthesis was performed with two contents of dopant (Ag+ or ...
Visible light-harvesting of TiO2 nanotubes array by pulsed laser deposited CdS
(Elsevier Science Bv, Amsterdam, 2014)
Titanium dioxide (TiO2) nanotubes arrays, obtained by anodization technique and annealing, were decorated with CdS using pulsed laser deposition method. Their structural, morphological and chemical characterization was ...
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 ...
