NMR analysis of 2-(2',3'-dihydro-1'H-inden-1'-yl)-1H-indene / NMR analiza 2-(2',3'-dihidro-1'H-inden-1'-il)-1H-indena
(Serbian Chemical Society, Belgrade, 2001)
1H, 13C and two dimensional NMR analyses were applied to determine the NMR parameters of 2-(2',3'-dihydro-1'H-inden-1'-yl)-1H-indene. The chemical shifts of all the H- and C-atoms, as well as the appropriate coupling ...
Dynamic mechanical analysis study of the curing of phenol-formaldehyde novolac resins
(Wiley, Hoboken, 2001)
The curing reaction of typical commercial phenol-formaldehyde novolac resins with hexamethylentetraamine (HMTA) was followed by dynamic mechanical analysis. The evolution of the rheological parameters, such as storage ...
Shrinkage properties of peroxide-enzyme-biopolymer treated wool
(Sage Publications Ltd, London, 2001)
Incorporating an enzyme in the alkaline peroxide treatment bath enhances wool wettability and the effectiveness of subsequently applied chitosan biopolymer. Wool whiteness is also significantly enhanced. Wool knitted fabric ...

(University of Belgrade, Technical Faculty, Bor, 2001)
The object of this work was to determine Pitzer's ionic parameters, θ and Ψ, for the mixed salt solution H2O-NaCl-MgCl2 at following temperatures: 273.15, 298.15, 356.15 and 378.15 K in ionic strength interval from 7 to ...
Prediction of thermal shock behavior of alumina based refractories: Temperature difference, fracture resistance parameters and water quench
(Trans Tech Publications Ltd, Durnten-Zurich, 2001)
In this paper temperature difference and fracture resistance parameters were used for prediction of thermal shock behavior of the samples. Materials were alumina based commercial refractories with different content of Al2O3 ...
Starter cultures for semi hard cheese / Starter kulture za polutvrdi sir
(Univerzitet u Novom Sadu - Tehnološki fakultet, Novi Sad i Savez hemičara i tehnologa, Beograd, 2001)
29 starter cultures for semi hard cheese are formed from natural isolates of lactic acid bacteria. They are isolated from traditionally home made cheese produced without the addition of starter cultures. Natural isolates ...
Material properties and thermal shock behavior of alumina based refractories
(Belgian Ceramic Soc, Mons, 2001)
Materials were five alumina based commercial refractories with different contents of ( Al2O3 + TiO2) from 28 % to 78 %. Thermal and mechanical properties of the chosen materials, were measured using standard laboratory ...
