Overhaul and reconstruction of an autoclave / Sanacija i rekonstrukcija autoklava
(Society for Structural Integrity and Life, Institute for Material Testing, 2008)
The project of overhaul and redesign of autoclaves, a substantial part of coal drying equipment is realized at the requirement of Kolubara Prerada-Vreoci. Autoclaves operate under pressure at elevated temperature. Frequent ...
The effects of zeolite and silica gel on synthesis of amylisobutyrate catalyzed by lipase from Candida rugosa / Uticaj zeolita i silika gela na sintezu amil-izobutirata katalizovanu lipazom iz Candida rugosa
(Association of Chemical Engineers of Serbia, 2008)
Lipase-catalyzed synthesis of esters has been widely investigated due to numerous advantages in comparison with the conventional chemical process catalyzed with concentrated acids since use of chemical catalysts leads to ...
A correlation for heat of vaporization of pure compounds
(Korean Institute Chemical Engineers, Seoul, 2008)
Twenty-seven selected equations were tested on 162 compounds with 1958 calorimetric data for their abilities to reflect the temperature influence on the heat of vaporization of pure compounds. A new equation is recommended ...
Surface characteristics and antibacterial activity of a silver-doped carbon monolith
(Natl Inst Materials Science, Ibaraki, 2008)
A carbon monolith with a silver coating was prepared and its antimicrobial behaviour in a flow system was examined. The functional groups on the surface of the carbon monolith were determined by temperature-programmed ...
A fracture mechanics approach to thermal shock investigation in alumina-based refractory
(9th International Conference on Multiscale and Functionally Graded Materials, FGM IX, 2008)
The thermal shock behavior of large grain size, alumina-based refractories was investigated experimentally using a standard water quench test. A mathematical model was employed to simulate the thermal stability behavior. ...
Antibacterial effect of silver nanoparticles deposited on corona-treated polyester and polyamide fabrics
(Wiley, Hoboken, 2008)
The possibility of using a corona treatment (electrical discharge at atmospheric pressure) for fiber surface activation, which can facilitate the loading of silver nanoparticles (NPs) from colloids onto the polyester (PES) ...
Analysis of smart aramid fiber reinforced laminar thermoplastic composite material under static loading / Analiza SMART aramidnim vlaknom ojačanih laminarnih termoplastičnih kompozitnih materijala tokom statičkog opterećivanja: poređenje eksperimentalnih rezultata i numeričke simulacije
(Military Technical Institute, Belgrade, 2008)
In order to obtain a composite material with desired improved resistance to penetration of ballistic projectiles, a poly(p-phenyleneterephthalamide) reinforced laminar thermoplastic composite material has been made. This ...
The influence of bonding agents in improving interactionsin composite propellants determined using image analysis
(Wiley, Hoboken, 2008)
Binder-oxidizer interactions in rocket composite propellants can be improved using adequate bonding agents. In the present work, the effectiveness of different 1,3,5-trisubstituted isocyanurates was determined by stereo ...
The effects of hemicelluloses and lignin removal on water uptake behavior of hemp fibers
(Elsevier Sci Ltd, Oxford, 2008)
This study investigated the individual influences of hemicelluloses and lignin removal on the water uptake behavior of hemp fibers. Hemp fibers with different content of either hemicelluloses or lignin were obtained by ...
Thermal shock damage characterization of high temperature ceramics by non destructive test methods
(University of Chemistry and Technology, Prague, 2008)
In the present work a mixture of commercially available spinel, quartz (SiO2) and alumina (Al2O3) corresponding to cordierite stoichiometry was used as starting material for obtaining cordierite/SiC composite ceramics with ...
