On the role of working fluid properties in Organic Rankine Cycle performance
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
The performance of ORC systems strongly depends on working fluid properties. We explore the relationships between working fluid properties and ORC common economic and thermodynamic performance criteria from a theoretical ...
Experimental and numerical analysis of local mechanical properties of globe valve housing
(Chemicke Listy, 2012)
Experimental and Numerical Analysis of Local Mechanical Properties of Globe Valve Housing One of the most widely used industrial valves is globe valve. Due to wide industrial application, the valve is subjected to various ...
Influence of Cr, Mn and Mo Addition on Structure and Properties of V Microalloyed Medium Carbon Steels
(Journal Mater Sci Technol, Shenyang, 2012)
The effect of austenitizing temperature and Cr, Mo and Mn addition on microstructure and mechanical properties of V microalloyed medium carbon steel has been studied by means of metallography and mechanical testing. The ...
Versatile use of biomimetic bioreactors for functional evaluation of nanocomposite alginate based hydrogels
(Wiley-Blackwell, Hoboken, 2012)
Exchange-Bias and Grain-Surface Relaxations in Nanostructured NiO/Ni Induced by a Particle Size Reduction
(Amer Chemical Soc, Washington, 2012)
Transition-metal-oxide/transition-metal nanocomposites, such as NiO/Ni, FeO/Fe, and CoO/Co, have been the subject of much recent investigation (i) because of their potential applications and (ii) because they are good model ...
Quantification of viable spray-dried potential probiotic lactobacilli using real-time PCR
(Srpsko biološko društvo, Beograd, i dr., 2012)
The basic requirement for probiotic bacteria to be able to perform expected positive effects is to be alive. Therefore, appropriate quantification methods are crucial. Bacterial quantification based on nucleic acid detection ...
Premazi na bazi cirkona sa primenom u Lost Foam procesu livenja / Zircon-based coating for the applications in Lost Foam casting process
(Savez hemijskih inženjera, Beograd, 2012)
U ovom radu je istraživana mogućnost dobijanja novih vatrostalnih premaza na bazi cirkona koji bi imali primenu u livarstvu. Optimizacija sastava premaza kontrolisana reološkim svojstvima postignuta je primenom različitih ...
Precipitation of the beta-phase and corrosion behavior of an al-6.8 wt.% mg alloy
(John Wiley & Sons, Chichester, 2012)
This study was performed on the Al-Mg alloy with the chemical composition: Al-Mg6.8-Mn0.51-Fe0.2-Si0.1. As-received cold rolled material (O-temper) was subjected to (i) cold rolling and annealing at 265 degrees C and 320 ...
The phase equilibrium of triglycerides and ethanol at high pressure and temperature: The influence on kinetics of ethanolysis
(Elsevier Science Bv, Amsterdam, 2012)
Biodiesel synthesis by ethanolysis of triglycerides conducted under high pressure and at elevated temperature can lead to high levels of conversion and biodiesel yield over short reaction time. The vapour-liquid or ...
