Prediction for debonding damage process of glass beads-reinforced modified polyphenylene oxide under simple shear
(Elsevier Science Sa, Lausanne, 2005)
A three-dimensional finite element cell modeling technique has been applied to predict the particle-matrix debonding process of particulate polymer composite (PPC) subject to simple shear loading. The particle-matrix ...
Barium strontium titanate powders prepared by spray pyrolysis
(Elsevier Science Sa, Lausanne, 2005)
Ultasonic spray pyrolysis (SP) has been investigated for the production of the barium strontium titanate (BST) powders from the polymeric precursors. The processing parameters, such as flux of aerosol and temperature profile ...
Effect of low-temperature plasma and chitosan treatment on wool dyeing with acid red 27
(John Wiley & Sons Inc, Hoboken, 2005)
This study examines in detail the influence of low-temperature plasma and biopolymer chitosan treatments on wool dyeability. Wool knitted fabrics were treated and characterized by whiteness and shrink-resistance measurements. ...
Nanostructured sodium lithium niobate and lithium niobium tantalate solid solutions obtained by controlled crystallization of glass
(Elsevier Science Sa, Lausanne, 2005)
Transparent, nanostructured glass ceramics based on ferroelectric solid solutions of the type Na1-xLixNbO3 (in very narrow composition regions for x=0.12 and 0.93) and LiNb1-yTayO3 (y=0.5 unlimited solid solubility), can ...
Chitosan application on wool before enzymatic treatment
(Wiley Periodicals, Inc., 2005)
The influence of a chitosan application on wool fabric before a treatment with a proteolytic enzyme has been investigated. The enzymatic treatment enhances whiteness and confers shrink resistance to wool, but an increase ...
Structural and crystallization characteristics of K 2 O· TiO 2 ·3GeO 2 glass / Strukturní a krystalizaèní charakteristiky k2o·tio2·3geo2 skel
(Institute of Chemical Technology, 2005)
Structure and crystallization of K 2 O·TiO 2 ·3GeO 2 glass have been investigated by means of Fourier transform infrared spectroscopy (FTIR), differential thermal analysis (DTA), differential scanning calorimetry (DSC), ...
Comparison of Hydroxyapatite Sorption Properties Towards Cadmium, Lead, Zinc and Strontium Ions
(Trans Tech Publications, 2005)
Apatites are well known matrix for heavy metal immobilization and remediation of
ground water and contaminated soils. In this work, capacities of different synthetic hydroxyapatite
(HAP) samples for Pb, Cd, Sr and Zn ...
Comparative analysis of laboratory accreditation in Bulgaria, Lithuania, Slovakia and Serbia and Montenegro
(Springer-Verlag, 2005)
The development of an internationally recognized laboratory accreditation process, accompanied by a mutual recognition agreement (MRA), is an issue of great interest in Central and Eastern European countries. This paper ...
Glass formation and crystallisation behaviour of nanostructured sodium niobate by direct glass crystallisation
(Physics and Chemistry of Glasses, 2005)
The subject of this work is the study of nanostructured sodium niobate obtained by a controlled crystallisation of glass. The glass samples of the composition within the system NaNbO3-SiO2-Al2O3 were prepared by melting ...
Processing of ferroelectric thin layers of barium titanate by the sol-gel method
(Physics and Chemistry of Glasses, 2005)
The influence of various processing parameters is investigated during sol formation (metal precursors: titanium (IV) butoxide, barium hydroxide, barium acetate; pH of sol solution; type and amount of stabiliser and solvent; ...
