(Naučno-stručno društvo za zaštitu životne sredine Srbije - Ecologica, Beograd, 2008)
The basic characteristics of technological waste waters and industrial waste of agricultural industry, as well as of industry of fruit processing and production of juices, are high values of organic contamination and ...
Semi-interpenetrating polymer networks of chitosan and poly(ethylene glycol) / Semi-interpenetrirajuće mreže hitozana i poli(etilen glikola)
(Association of Chemical Engineers of Serbia, 2008)
Chitosan is a natural polycationic polymer that possesses useful properties such as bioactivity, biocompatibility, non-toxicity and non-antigenicity. On the other hand, its mechanical properties are not good for some ...
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 ...
The ionic equilibrium in the CuSO4-H2SO4-H2O system and the formation of the honeycomb-like structure during copper electrodeposition / Jonska ravnoteža u sistemu CuSO4-H2SO4-H2O i formiranje strukture pčelinjeg saća elektrohemijskim taloženjem bakra
(Serbian Chemical Society, 2008)
The ionic equilibrium of the species in the CuSO4-H2SO4-H2O system was employed to systematize the conditions of copper electrodeposition leading to the formation of the honeycomb-like structure. The reason why CuSO4 ...
Antimicrobial textile prepared by silver deposition on dielectric barrier discharge treated cotton/polyester fabric
