Determination of new ASOG-H parameters of CyCH, furfural and DMSO groups
(Serbian Chemical Society, Belgrade, 1996)
New interaction parameters for the groups CYCH(1)-furfural(2) and CyCH(1)-DMSO(2) of the ASOG-H model were determined, for 293.15 K-323.15 K and 303.15 K-323.15K respectively. The values of the CyCH(1)-furfural(2) parameters ...
Low temperature processes during the synthesis of lanthanum lead borosilicate glasses
(Serbian Chemical Society, Belgrade, 1997)
Low temperature processes during the synthesis of PbO-B 2 O 3 -SiO 2 -La 2 O 3 glasses were studied by thermal analysis of the batch mixture of glasses and X-ray powder diffraction analysis of samples that crystallized ...
Corrosion behaviour of polyester and fluoropolymer coatings on coil coated stainless steel
(Serbian Chemical Society, Belgrade, 1996)
Coil coated stainless steel is a new material for applications in civil and industrial fields with the purpose of reducing maintenance costs and increasing the service life of the products. The corrosion behaviour of ...
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 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 ...
Application of the MvdW1 and HVOS-NRTL mixing rules to the simultaneous correlation of excess enthalpies and W-shaped excess heat capacities data of 1,3-dioxolane plus n-alkane systems
(Serbian Chemical Society, Belgrade, 1999)
The Peng-Robinson-Stryjek-Vera (PRSV) equation of state (EOS) coupled with a modified two parameter van der Waals one-fluid mixing rule (MvdW1) and the Huron-Vidal-Orbey-Sandler mixing rule incorporating the NRTL equation ...
31 P MAS NMR investigation of some microporous zincophosphates
(Serbian Chemical Society, Belgrade, 1996)
High field magic-angle spinning (MAS) 31 P-NMR investigations of novel porous zincophosphates and their cobalt-containing derivatives confirm the framework structure of alternating Zn(Co)O 4 and PO 4 tetrahedra. The MAS ...
Preparation of thermoplastic starch
(Serbian Chemical Society, Belgrade, 1997)
Native starch and WX-starch, i.e., native starch enriched with amylopectin, were mixed with plasticizers and thermomechanically treated in a twin screw mixer in order to obtain thermoplastic starch. Ethylene glycol, propane ...
Some aspects of the quantitative analysis of cyclic nucleotides by fast-atom bombardment mass spectrometry
(Serbian Chemical Society, Belgrade, 1996)
The possibilities of the quantitative analysis of cyclic nucleotides by fast-atom bombardment are examined. Aspects such as the amount of matrix, the formation of protonatcd ion species and the presence of more than one ...
