Diffusional processes in the biomass conversion
(Slovnaft VÚRUP, 2012)
Diffusional process with biochemical reaction was investigated. Fermentation for ethanol production with Saccharomces Cerevisia was carried out with Ca-alginate gel in the form of layer spherical beads in the anaerobic ...
Poly(urethane-siloxane)s based on hyperbranched polyester as crosslinking agent: Synthesis and characterization / Poli(uretan-siloksani) na bazi hiperrazgranatog poliestra kao umreživača - sinteza i karakterizacija
(Serbian Chemical Society, 2012)
A series of novel polyurethane crosslinked structures (PUs) was prepared from α,ω-dihydroxy-(ethylene oxide-poly(dimethylsiloxane)-ethylene oxide) (EO-PDMS-EO), 4,4'-methylenediphenyl diisocyanate and Boltorn ® hyperbranched ...
Relationship between the common optical basicity models and the sulphide capacities of CaO-Al 2O 3-SiO 2-MgO slag
(Slovenska Akademia Vied, 2012)
The correlations between the sulphide capacity and the optical basicity models available in literature are reviewed. The relationship between sulphide capacity and the optical basicity was investigated on plant data collected ...

Investigations in this paper has been carried out in order to define the correlation between specific characteristics of coating glazes based on basalt, fired faience and appearance and the quality of the ceramic product ...
A coupled thermo-mechanical model of friction stir welding
(Vinca Institute of Nuclear Sciences, 2012)
A coupled thermo-mechanical model was developed to study the temperature fields, the plunge force and the plastic deformations of Al alloy 2024-T351 under different rotating speed: 350, 400, and 450 rpm, during the friction ...
Determination of kinetic parameters for the hydrogen evolution reaction on the electrodeposited Ni-MoO2 composite coating in alkaline solution
(Elsevier Science Sa, Lausanne, 2012)
As a result of research on the non-noble metal-based composite electrocatalysts for the hydrogen evolution reaction (HER), the Ni-MoO2 composite coating was produced by electrodeposition from an NH4Cl and NiCl2 containing ...
