A novel platinum-based nanocatalyst at a niobia-doped titania support for the hydrogen oxidation reaction
(Journal of the Serbian Chemical Society, 2011)
The kinetics of the hydrogen oxidation reaction (HOR) was studied at Pt nanoparticles supported on niobia-doped titania (Pt/N-T). The catalyst support, with the composition of 0.05NbO(2.5-delta)-0.995TiO(2) (0 LT delta LT ...
Numerical simulation of constraint effect on fracture initiation in welded specimens using a local damage model / Numerička simulacija uticaja veze na inicijaciju loma kod zavarenih epruveta upotrebom modela lokalnog oštećenja
(Society for Structural Integrity and Life, Institute for Material Testing, 2011)
In this paper, two micromechanical models: the Gurson-Tvergaard-Needleman (GTN) model and Complete Gurson Model (CGM) are used to predict ductile fracture initiation of two different welded specimens, SE(B) and C(T). The ...
CFD analysis of exothermic reactions in al-au nano multi-layered foils
(Institute of Metals and Technology, 2011)
This work presents the possibility of numerical modelling using Computational Fluid Dynamics (CFD) in the field of nano-foils. The governing equations were solved using a Finite Volume Methodology (FVM). The computational ...
A mathematical model of the current density distribution in electrochemical cells / Matematički model raspodele gustine struje u elektrohemijskim ćelijama
(Serbian Chemical Society, 2011)
An approach based on the equations of electrochemical kinetics for the estimation of the current density distribution in electrochemical cells is presented. This approach was employed for a theoretical explanation of the ...
