Polysulfone membranes for ultra and microfiltration / Polimerne membrane za ultra i mikrofiltraciju na bazi polisulfona
(Tehnika - Novi materijali, 2002)
The influence of the propionic acid as nonsolvent additive on the properties of the prepared polysulfone membranes was investigated. The obtained results show that the membranes prepared from the polymer solutions with ...
Methanol electrooxidation on supported Pt and Pt/Ru catalysts in alkaline solution / Oksidacija metanola na Pt i Pt/Ru nanokatalizatorima u alkalnoj sredini
(Tehnika - Novi materijali, 2003)
The kinetic of methanol oxidation on 47.5 wt% Pt and 54 wt% Pt/Ru catalysts supported on high surface area carbon are measured in 0.1 M NaOH at 295 K and 333 K. The catalysts used were characterized by using TEM and XRD ...
Synthesis of amorphous boron carbide by single and multiple charged boron ions bombardment of fullerene thin films / Sinteza amorfnog bor karbida bombardovanjem tankih slojeva fulerena jonima bora
(Tehnika - Novi materijali, 2006)
In this paper, results of structural modification of fullerene thin films by single and multiple charged boron ions (B+, B3+) are presented. The applied ion energies were in the range of 15 to 45 keV. The characterization ...
Structural modification of fullerene thin films by highly charged iron ions / Strukturne modifikacije tankih slojeva fulerena pri bombardovanju višestruko naelektrisanim jonima gvožđa
(Tehnika - Novi materijali, 2007)
In this paper, the results of structural modification of fullerene thin films bombarded by highly charged iron ions (Fe6+) have been presented. The properties of as-deposited and irradiated fullerene thin films have been ...
Lasersko čišćenje nepoželjne patine nakita / Laser cleaning of unwanted jewelry patina
(Савез Инжењера и техничара Србије, Београд, 2022)
Женска огрлица, филигран са непожељном патином, чишћена је Nd:YAG ласером. Током експеримента варирани су параметри ласера: таласна дужина, флуенца и број импулса, односно време озрачавања. Испитиван је утицај наведених ...
The application of modified macroporous poly(GMA-co-EGDMA) in the metal ions sorption from aqueous solutions / Primena modifikovanog makroporoznog poli(GMA-co-EGDMA) kopolimera u sorpciji jona metala iz vodenih rastvora
(Tehnika - Novi materijali, 2002)
Macro porous cross linked poly(GMA-co-EGDMA) copolymer synthesized by radical suspension copolywerization was modified by ring-opening reaction of the pendant epoxy groups with ethylene diamine, EDA. Sorption capacities ...
