Using geothermal water for greenhouse heating
(Vinca Institute of Nuclear Sciences, 2006)
On construction with dimensions 15 x 5 x 2 m, conditions of temperature transmission and vegetables growth are examined. We have been cultivating pepper, cucumber, small cucumber, tomato, and lattice. Over ground heating ...
Osmotic coefficient of the ZnSO4(aq) at T=298.15 K
(Academic Press Ltd- Elsevier Science Ltd, London, 2002)
The osmotic coefficient of ZnSO4(aq) has been measured at T = 298.15 K by the iso-piestic method, in the range of molalities from 1.3 to 3.0 mol . kg(-1), with KCl(aq) as the reference solution. Experimental data of osmotic ...
Synthesis and characterization of biodegradable aliphatic copolyesters with hydrophilic soft segments / Sinteza i karaterizacija biodegradabalnih alifatičnih kopoliestara modifikovanih mekim hidrofilnim segmentima
(Serbian Chemical Society, Belgrade, 2004)
segmented poly(ester-ether)s based on poly(butylene succinate) and two different types of polyethers were investigated. The poly(ester-ether)s were synthesized by transesterification reaction of dimethyl succinate ...
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, ...
Temperature dependence of the kinetics of oxygen reduction on carbon-supported pt nanoparticles / Temperaturna zavisnost elektrohemijske redukcije kiseonika na nanočesticama platine na ugljeničnom nosaču
(Serbian Chemical Society, Belgrade, 2008)
The temperature dependence of oxygen reduction reaction (ORR) was studied on highly dispersed Pt nanoparticles supported on a carbon cryo-gel. The specific surface area of the support was 517 m2 g-1, the Pt particles ...
Electrochemical deposition and corrosion stability of Zn-Co alloys
(Springer, New York, 2009)
Electrochemically deposited Zn-Co alloys under various deposition conditions were investigated using anodic linear sweep voltammetry for phase structure determination, scanning electron microscopy for surface morphology ...
Efficiency of recycled wool-based nonwoven material for the removal of oils from water
(Pergamon-Elsevier Science Ltd, Oxford, 2008)
The aim of this study was to highlight the potential use of recycled wool-based nonwoven material for the removal of diesel fuel, crude, base, vegetable and motor oil from water. Sorption capacity of the material in water ...
The effect of low-temperature plasma pretreatment on wool printing
(Amer Assoc Textile Chemists Colorists-Aatcc, Res Triangle Pk, 2000)
The application of radio-frequency capacitively coupled plasma for the treatment of wool was studied. The influence of plasma parameters on the printing and mechanical properties of wool was determined. Results after plasma ...
Volumetric properties of the ternary system ethanol plus 2-butanone plus benzene by the van der Waals and Twa-Coon-Bluck-Tilton mixing rules: experimental data, correlation and prediction
(Elsevier, Amsterdam, 2004)
Densities of the ternary system ethanol + 2-butanone + benzene and its binaries ethanol + 2-butanone, ethanol + benzene and 2-butanone + benzene were measured at T = 298.15 K and atmospheric pressure. From these densities ...
Thermodynamic and structural investigation of the Ag-In-Sb system
(Croatian Metallurgical Society, 2007)
The Ag-In-Sb ternary system presents one of the possible lead-free solder candidates. Therefore, the results of thermodynamic study of the alloys in the Ag-In-Sb alloys, obtained using general solution mode!, are presented ...
