Wool fabric characterisation after enzymatic and chlorinating treatment / Karakterizacija vunenog tekstilnog materijala posle enzimske obrade i obrade hlorovanjem
(Union of Textile Engineers and Technicians of Serbia, Belgrade, 1999)
Properties of wool textile products are partly governed by morphological composition and chemical structure of the surface of wool fibre. Both chemical structure and morphological composition are most frequently changed ...
Determination of multiaxial stress linear dimensional change of textile surfaces / Određivanje promene linearnih dimenzija tekstilnih površina pri multiaksijalnom naprezanju
(Savez inženjera i tehničara tekstilaca Srbije, 1999)
Breaking characteristics of loose woven and knitted fabrics are frequently determined by the ball penetration resistance (bursting) (test). The Yugoslav Standard JUS F.S2.022 does not include the determination of sample ...
Study of the structure of phenol-formaldehyde novolac resins by NMR spectroscopy and gel-permeation chromatography
(Serbian Chemical Society, Belgrade, 1999)
C-13-NMR spectroscopy and gel-permeation chromatography studies were carried out on different samples of typical commercial phenol-formaldehyde novolac resins. Six random novolac resins (NLO 1-6), with decreasing ratios ...
Influence of aerosol formation mechanism by an ultrasonic field on particle size distribution of ceramic powders
(Elsevier Science Bv, Amsterdam, 1999)
Aerosol droplet genesis by ultrasonic atomization has been theoretically studied using a model for three-dimensional spherical/ellipsoidal waves generated by excitation of a system of given geometry by forced frequency of ...
Bioreactor cultivation conditions modulate the composition and mechanical properties of tissue-engineered cartilage
(Wiley, Hoboken, 1999)
Cartilaginous constructs have been grown in vitro with use of isolated cells, biodegradable polymer scaffolds, and bioreactors. In the present work, the relationships between the composition and mechanical properties of ...
Mass and momentum transfer in packed beds of spherical inert particles
(Serbian Chemical Society, Belgrade, 1996)
Mass transfer coefficients between fluid and immersed sphere in liquid dense and loose packed beds of spherical inert particles have been studied experimentally using column 40 mm in diameter. Mass transfer data were ...
The interfacial stability of magnetically stabilized fluidized beds
(Serbian Chemical Society, Belgrade, 1996)
The study concerns a phenomenon in which the magnetization of ferromagnetic particles stabilizes the state of uniform fluidization in gas-solid, liquid-solid and gas-liquid-solid fluidized beds. Fluidization regimes and ...
Complexes cobalt(II), zinc(II) and copper(II) with some newly synthesized benzimidazole derivatives and their antibacterial activity
(Serbian Chemical Society, Belgrade, 1999)
The preparation and properties of some complexes of cobalt(II), zinc(II) and copper(II) with several newly synthesized benzimidazole derivatives (L) are reported, The complexes, of the general formula [MCl2(L)over dot(2)] ...
Mass spectrometric study of glassy carbon surface stability
(Serbian Chemical Society, Belgrade, 1996)
The combinaton of temperature-programmed desorption (TPD) and quadrupole mass spectrometry was used to investigate glassy carbon surface stability. TPD experiments provide valuable information about the nature and the ...
Reactivity of beta-aroylacrylic acids with diazodiphenylmethane
(Serbian Chemical Society, Belgrade, 1998)
The rate constants for 10 trans-substituted beta-aroylacrylic acids in their reaction with diazodiphenylmethane (DDM) were determined in ethanol at 30 degrees C. The intention was to study the transmission of electronic ...
