Cobalt impregnated smectites (raw and acid activated) as catalysts in organic dye oxidation process in the presence of peroxymonosulfate generated radicals
(Clay Minerals Society, 2019)
Smectite based Co catalysts were prepared using the wetness impregnation method and applied as activators of potassium peroxymonosulfate as the source of sulfate radicals and tested in the degradation of Acid Orange 10 ...
Optimizacija parametara laserske površinske obrade u cilju poboljšanja mehaničkih osobina austenitnih materijala
(Beograd : Univerzitet u Beogradu - Mašinski fakultet, 2014)
Prikazano tehničko rešenje se primenjuje za poboljšanje mehaničkih osobina delova izrađenih od austenitnih materijala, pre svega superlegura nikla, koji se koriste za rad na povišenim temperaturama i pritiscima. Visoke ...
A novel Tc 99m sorbent based on macroporous magnetic polymer
(Society of Physical Chemists of Serbia, 2016)
A novel magnetic macroporous poly(glycidyl-co-ethylene glycol
dimethacrylate) (mPGME) synthesized by suspension copolymerization and
functionalized with diethylene triamine (mPGME-deta) was evaluated as
sorbent for ...
X-ray transparent testing of thin elements of an artistic part
(Sopot : Scientific Association for Development and Affirmation of New Technologies, 2017)
For investigation of artistic components, generally, there are not many developed and usable testing methods. One of the available method for such investigation is radiographic testing. For useful application of this method ...
Analysis of Efficacy of the Process of Remediation of Landfill Site Soil Contaminated with Leachate using Material Flow Analysis / Analiza efikasnosti procesa remedijacije zemljišta deponijskog lokaliteta kontaminiranog procednim vodama primenom analize tokova materijala
(Univerzitet u Beogradu - Tehnički fakultet u Boru, 2018)
There are two possible cases concerning non-sanitary municipal solid waste landfills due to failure to meet requirements with respect to impermeability and thickness of geological barrier as well as absence of implementation ...
Tartrazine azo-dye degradation using Co-impregnated Al-pillared clay and Oxone: influence of temperature
(Serbian Ceramic Society, 2017)
Heterogneous Fenton-like reaction is one of the most efficient solutions for the
degradation of organic pollutants in water. A variant of this reaction involves the application
of Oxone reagent, based on potassium ...
Kinetics of adsorption of nicotine by natural and acid-activate montmorillonite
(Society of Physical Chemists of Serbia, 2016)
The adsorption of nicotine from aqueous solutions was performed on natural
and acid-activated Wyoming montmorillonite. The adsorption experiments
showed that acid-activation increases adsorption capacity of
montmorillonites ...
Organobentonites as Multifunctional Adsorbents of Organo/inorganic Aquatic Mixtures
(Serbian Ceramic Society, 2012)
Partial substitution of naturally present cations in the interlayer region of bentonite clay with quaternary alkyl ammonium cations (QAACs) with 16 carbon atoms in one alkyl chain was
performed. The amount of QAACs used ...
Aggregation problem of dye monolayer in dye sensitized solar cells
(University of Belgrade - Institute of Chemistry, Technology and Metallurgy, 2017)
Dye sensitized solar cells are photovoltaic devices which simulate photosynthesis [1,2]. Comparing to other solar cells, they cost less and are easy to manufacture. One of themost important parts of this system is adye. A ...
Study on preparation and properties of novel functionalized polyester copolymers based on siloxanes
(Belgrade : Serbian Chemical Society, 2013)
Novel functionalized macroporous copolymers were synthesized by reaction of the
pendant epoxy groups of poly(glycidyl methacrylate)-co-poly(ethylene glycol dimethacrylate)s with 1,3-bis(3-aminopropyl)tetramethyldisiloxane ...
