Elektrohemijska oksidacija jodid-jona u vodenim rastvorima
(Engineering Society for Corrosion, Belgrade, Serbia, 2005)
The electrochemical reaction of iodine ions oxidation was investigated in order to estimate the optimal conditions for electrolysis. The anodic polarization curves were determined in solutions of different KI concentration: ...
Recycled wool-based nonwoven material for sorption of acid dyes
(Niscair, 2005)
The possibility of using a nonwoven material based on recycled wool for sorption of acid dyes from wastewater has been studied. To,improve its sorption properties, the recycled wool-based nonwoven material was treated with ...
Synthesis and single-crystal structure analysis of a new layered zinc phosphate
(Pure and Applied Chemistry, 2005)
A new 2D zinc phosphate [H3NCH(CH3)CH 2NH3]2+0.75[COOH(CH 2)COOH]0.25 (Zn3P3O 11OH)2-* 0.5NH4+ consists of zinc phosphate layers, which are intercalated by diprotonated 1,2-diaminopropane, malonic acid, and NH4+ ions. The ...
Chitosan application on wool before enzymatic treatment
(Wiley Periodicals, Inc., 2005)
The influence of a chitosan application on wool fabric before a treatment with a proteolytic enzyme has been investigated. The enzymatic treatment enhances whiteness and confers shrink resistance to wool, but an increase ...
The growth of ruby single crystals / Раст монокристала рубина
(Serbian Chemical Society, 2005)
Ruby (Cr:Al2O3) single crystals were grown by the Czochralski technique in an argon atmosphere. The critical crystal diameter dc = 1.0 cm and the critical rate of rotation ωc = 20 rpm were calculated by equations of the ...
The gas holdup in a multiphase reciprocating plate column filled with carboxymethylcellulose solutions / Утицај концентрације раствора и степена полимеризације карбоксиметилцелулозе на садржај гаса у реактору са вибрационом мешалицом
(Serbian Chemical Society, 2005)
Gas holdup was investigated in a gas-liquid and gas-liquid-solid reciprocating plate column (RPC) under various operation conditions. Aqueous carboxymethylcellulose (sodium salt, CMC) solutions were used as the liquid ...
Open-framework aluminophosphates: Synthesis, characterization and transition metal modifications / Porozni alumofosfati - sinteza, karakterizacija i modifikovanje jonima prelaznih metala
(Serbian Chemical Society, Belgrade, 2005)
This review is a brief summary of open-framework aluminophosphates and their transition metal-substituted modifications. The materials exhibit structural and compositional diversity, as well as a wide range of pore openings, ...
Dynamic recrystallization in M2 tool steel during friction welding
(Savez inženjera metalurgije Srbije, Beograd, 2005)
Friction welding of M2 tool steel and 1730 quenched and tempered steel was performed with the aim to reveal the origin of extremely fine martensitic grain in M2 steel after welding. Taking into account thermomechanical ...
(C4H12N2)[Zn-2(PO4)(HPO4)(H2PO4)], a layered zinc phosphate with intercalated N-methylpropane-1,3-diaminium cations
