Solid-state NMR study of an open-framework aluminophosphate-oxalate hybrid
(Amer Chemical Soc, Washington, 2003)
Short-range order within a novel aluminophosphate-oxalate hybrid material with the unit cell formula CH2(NH3)CH(NH3)CH3Al4P6O20(OH)(4)(C2O4)H2O was studied by multinuclear solid-state NMR measurements. The C-13, Al-27, and ...
Kinetics of crystallization silicon-(IV)-nitride / Kinetika kristalizacije silicijum-(IV)-nitrida
(Savez inženjera metalurgije Srbije, Beograd, 2003)
Amorphous covalent Si-C-N ceramics have been synthesized by pyrolysis polysilazanes. This part of experiment was done in Institute für Nichtmetallische Anorganische Materialien, Universitaet Stuttgart, Germany. Ceramics ...
Embedding of optical fibers as sensors in thermoplastic composite laminates / Ugradnja optičkih vlakana kao senzora u slojevite termoplastične kompozitne materijale
(Institut bezbednosti, Beograd, 2003)
Application of optical fibers as sensors for the purpose of in-service health monitoring in composite materials have increased in last few years. Advantages of optical fiber sensors over conventional sensing methods are ...
An electrochemical illustration of the mathematical modelling of chlorine impact and acidification in electrochemical tumour treatment and its application on an agar-agar gel system
(Elsevier, 2003)
Electrochemical treatment (EchT) of tumours, which is also known as electrochemical therapy, implies that tumour tissue is treated with a direct current through the use of electrodes. This was shown earlier when the major ...
Immobilization of fish chromatophores for use as a micro-biosensor for biological toxins / Imobilizacija hromatofora riba radi korišćenja kao biosenzor za biološke toksine
(Association of Chemical Engineers of Serbia, 2003)
Chromatophores isolated from the Siamese fighting fish, Betta splendens represent a class of living cells that provide a vivid color response to microbial pathogens and environmental toxins. The selection of the most ...
The influence of steel surface modification by electrodeposited Zn-Fe alloys on the protective behaviour of an epoxy coating
(Elsevier Science Sa, Lausanne, 2003)
The electrochemical and transport properties of epoxy coatings electrodeposited on steel and steel modified by Zn-Fe alloys were investigated during exposure to 3% NaCl. The Zn-Fe alloys were deposited on steel surface ...
Synthesis and characterization of biodegradable poly(butylene succinate-co-butylene fumarate)s
(Pergamon-Elsevier Science Ltd, Oxford, 2003)
A series of aliphatic biodegradable polyesters modified with fumaric residues was synthesized by transesterification in the melt of dimethyl succinate, dimethyl fumarate and 1,4-butanediol. The amount of unsaturation, ...
Influence of modification of hemp fibres by sodium hydroxide on their chemical composition and sorption properties / Uticaj modifikovanja vlakana konoplje natrijumhidroksidom na njihov hemijski sastav i sorpciona svojstva
(Union of Textile Engineers and Technicians of Serbia, Belgrade, 2003)
This paper discusses the effect of chemical modification of hemp fibres with NaOH on their physico-chemical properties. The modification of hemp fibres was carried out with 5% and 18% aqueous solution of sodium hydroxide, ...
Osmotic coefficient of the ZnCl2(aq) at T=298.15 K
(Academic Press Ltd- Elsevier Science Ltd, London, 2003)
The osmotic coefficient of ZnCl2(aq) has been measured at T = 298.15 K by the isopiestic method over the range of molalities from (0.4 to 2.4) mol . kg(-1) with KCl(aq) as the reference solution. The available literature ...
Surface characterization of keratin fibres treated by water vapour plasma
(Wiley, Hoboken, 2003)
The effect of water vapour plasma treatment on the shrinkage behaviour and chemical properties of the surface of keratin fibres was studied. The wettability and shrink resistance of wool were improved even at low plasma ...
