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. ...
Development of a microbiosensor based on fish Chromatophores immobilized on ferromagnetic gelatin beads
(University of Zagreb, 2005)
Development of a microbiosensor based on immobilized living chromatophores of Siamese fighting fish, Betta splendens, for the detection of microbial and environmental toxins is described in this paper. Chromatophores were ...
Linear free energy relationships of the H-1 and C-13 NMR chemical shifts of 3-methylene-2-substituted-1,4-pentadienes
(Elsevier Science Bv, Amsterdam, 2005)
Linear free energy relationships (LFER) were applied to the H-1 and C-13 NMR chemical shifts (delta(N), N=H-1 and C-13, respectively) in the unsaturated backbone of cross-conjugated trienes 3-methylene-2-substituted-1,4- ...
Effect of substituents on the C-13 chemical shifts of the azomethine carbon atom of N-(substituted phenylmethylene)-3-and-4-aminobenzoic acids
(Elsevier Science Bv, Amsterdam, 2005)
C-13 chemical shifts of the azomethine carbon atom for N-(substituted phenylmethylene)-3- and -4-aminobenzoic acids having a wide range of substituent effects, were determined in deuterated DMSO solution. Good Hammett ...
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; ...
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), ...
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 ...
