Površinska modifikacija zeolita i uticaj pH i jonske jačine na desorpciju amina / Surface modification of a zeolite and the influence of pH and ionic strength on the desorption of an amine
(Srpsko hemijsko društvo, Beograd, 2006)
Ispitivan je uticaj temperature na adsorpciju stearildimetilbenzil-amonijum-hlorida (SDBAH ) na prirodnom zeolitskom tufu. Maksimalna adsorbovana količina SDBAH iznosila je 123 mmol/kg zeolita u slučaju termičkog tretiranja ...
Elektroforetsko taloženje i sinterovanje prevlaka bemita na titanu / Electrophoretic deposition and thermal treatment of boehmite coatings on titanium
(Srpsko hemijsko društvo, Beograd, 2007)
Vodeni sol bemita je pripremljen peptizacijom Al(OH) 3 . Elektroforetsko taloženje prevlaka bemita iz vodenog sola vršeno je pri konstantnom naponu 1,0 do 10 V) i za konstantna vremena taloženja (10 do 30 min). Povećanje ...
Electrophoretically deposited hydroxyapatite-based composite coatings loaded with silver and gentamicin as antibacterial agents
(Srpsko hemijsko društvo, Beograd, 2019)
Increasing need for improved, compatible bone tissue implants led to the intensive research of novel biomaterials, especially hydroxyapatite (HAP)-based composite materials on titanium and titanium alloy surfaces. Owing ...
Diffusion models of gentamicin released in poly(vinyl alcohol)/chitosan hydrogel
(Belgrade : Serbian Chemical Society, 2024)
This study presents comparison of our recently formulated two compartmental model with General fractional derivative (GFD) and Korsmeyer-Peppas, Makoid-Banakar and Kopcha diffusion models. We have used our GFD
model to ...
Influence of clay organic modifier on the morphology and performance of poly(epsilon-caprolactone)/clay nanocomposites
(Srpsko hemijsko društvo, Beograd, 2015)
Two series of poly(epsilon-caprolactone) poly(oxepan-2-one) nanocomposites with different organo-modified clays (1 to 8 wt. %) were prepared by the solution casting method. Organoclays with polar (Cloisite (R) C30B) and ...
Deashing and desulfurization of subbituminous coal from the East field (Bogovina Basin, Serbia) - Insights from chemical leaching
(Srpsko hemijsko društvo, Beograd, 2021)
The study is focused on the determination of the most effective chemical leaching process for the simultaneous demineralization/deashing and desulfurization of subbituminous coal from the Bogovina Basin. Coal was treated ...
Adsorpcija uranijum(VI)-jona na modifikovanom hejlanditsko/klinoptilolitskom zeolitskom tufu / Uranium(VI) adsorption on surfactant modified heulandite/clinoptilolite rich tuff
(Srpsko hemijsko društvo, Beograd, 2006)
U radu je ispitivana adsorpcija uranijum(VI)-jona na površinski modifikovanom hejlanditsko/klinoptilolitskom zeolitskom tufu (organozeolitu). Organozeoliti su dobijeni jonskom izmenom neorganskih katjona sa površine zeolita ...
The porosity and roughness of electrodeposited calcium phosphate coatings in simulated body fluid
(Srpsko hemijsko društvo, Beograd, 2015)
Calcium phosphate coatings were electrochemically deposited on titanium from an aqueous solution of Ca(NO3)(2) and NH4H2PO4 at a current density of 10 mA cm(-2) for a deposition time of 15 mm. The obtained brushite coatings ...
Mehanizam hidratacije mehanički aktiviranih smeša Portland cementa i letećeg pepela / Hydration study of mechanically activated mixtures of Portland cement and fly ash
(Srpsko hemijsko društvo, Beograd, 2007)
Leteći pepeo se može koristiti u cementnim smešama uz određena ograničenja. Problem navedenih smeša ogleda se u nedovoljnoj aktivnosti čestica LP u reakcijama koje su značajne za uspostavljanje mehaničkih karakteristika ...
Synthesis of the new lost foam refractory coatings based on talc
(Srpsko hemijsko društvo, Beograd, 2022)
This paper is focused on the preparation procedures, using a talc-based filler, to improve the rheologic properties of the lost foam refractory coatings. Talc, with grain size of 40 .m, was mechanically activated in a ...
