The representative particle of copper powder and branch of copper dendrites / Reprezentativna čestica bakarnog praha i grananje dendrita bakra
(Serbian Chemical Society, 2002)
Electrochemically deposited copper powders, which are formed of particles of different size and morphology, are characterized by some properties like specific surface and apparent density. Aprocedure of the determination ...
Electrochemical oxidation of methanol on Pt3Co bulk alloy / Elektrohemijska oksidacija metanola na leguri Pt3Co
(Serbian Chemical Society, Belgrade, 2003)
The electrochemical oxidation of methanol was investigated on a Pt3Co bulk alloy in acid solutions. Kinetic parameters such as transfer coefficient reaction orders with respect to methanol and H+ ions and energy of activation ...
The estimation of solid copper surface tension in copper sulfate solutions
(Journal of the Serbian Chemical Society, 2002)
In metal electrodeposition in the limiting diffusion current density range, the deposition current density remains constant regardless of the deposition overpotential used, At the same time, die larger the deposition ...
Drying of suspension and pastes in fluidized bed of inert particles / Sušenje suspenzija i pasta u fluidizovanom sloju inertnog materijala
(Serbian Chemical Society, 2000)
A fluid bed dryer with inert particles was used for the drying of suspensions and pastes. The effects of the operating conditions on the dryer throughput and on the product quality were investigated. Experiments were ...
Stabilization of alpha-glucosidase in organic solvents by immobilization on macroporous poly(GMA-co-EGDMA) with different surface characteristics / Stabilizacija α-glukozidaze u organskim rastvaračima imobilizacijom na makroporoznim (poli) glicidil metakrilatima različitih površinskih karakteristika
(Serbian Chemical Soc, Belgrade, 2006)
alpha-Glucosidase from baker's yeast was immobilized on macroporous copolymers of ethylene glycol dimethacrylate and glycidyl methacrylate, poly(GMA-co-EGDMA), with various surface characteristics and pore sizes ranging ...
Effect of non-stationary current regimes on the morphology of silver electrodeposits / Efekat nestacionarnih strujnih režima na morfologiju taloga srebra
(Serbian Chemical Society, Belgrade, 2009)
This work is concerned with the use of reverse current regimes in order to form small-grained and compact silver deposits during the electrorefining process. Several parameters were varied, i.e., i) anodic overpotential, ...
The effect of organic molecules adsorption on hydrogen absorption in relation to the hydrogen evolution reaction
(Serbian Chemical Society, 2001)
The competitive adsorption of organic molecules (2, 7-naphthalenedisulfonic acid) and adsorbed H is of interest in relation to its influence on H absorption into a Pd-Ni electro-deposited alloy. The experimental results, ...
The kinetics of the partial dehydration of gibbsite to activated alumina in a reactor for pneumatic transport
(Serbian Chemical Society, 2001)
The dehidration kinetics of gibbsite to activated alumina was investigated at four different temperatures between 883 K and 943 K in a reactor for pneumatic transport in the dilute two phase flow regime. The first order ...
The growth of ruby single crystals / Раст монокристала рубина
(Serbian Chemical Society, 2005)
Ruby (Cr:Al2O3) single crystals were grown by the Czochralski technique in an argon atmosphere. The critical crystal diameter dc = 1.0 cm and the critical rate of rotation ωc = 20 rpm were calculated by equations of the ...
A pseudo-fluid representation of vertical liquid-coarse solids flow / Vertikalno kretanje tečnosti i čvrstih čestica tretirano kao pseudo-fluid
(Serbian Chemical Society, 2005)
The pseudo–fluid concept has been applied for the prediction of the pressure gradient and voidage in vertical liquid-coarse solids flow. Treating the flowing mixture as a single homogenous fluid, the correlation for the ...
