Synthesis of nanosized calcium hydroxyapatite particles by the catalytic decomposition of urea with urease
(Cambridge Univ Press, New York, 2007)
Nanosized calcium hydroxyapatite particles were synthesized by the catalytic decomposition of urea with urease. The influence of the synthesis parameters, i.e., temperature and ratio of the reagents/urease concentrations, ...
The corrosion behaviour of epoxy-resin electrocoated steel
(Pergamon-Elsevier Science Ltd, Oxford, 1992)
a.c. Impedance measurements carried out on epoxy-resin electrocoated steels have been used to determine the pore resistance of the organic films as a function of time of exposure to 3% NaCl solution. The time dependence ...
Synthesis and rheological study of some maleic acid and fumaric acid stereoregular polyesters - 8. Unsaturated polyester fibers
(Springer, New York, 1992)
First unsaturated polyester fibers were prepared starting from stereoregular, macromolecular poly(octamethylene fumarate). Fibers obtained from octamethylene copolyesters of fumaric and terephthalic acids manifested improved ...
Formic acid oxidation on pure and Bi-modified Pt(111): Temperature effects
(Amer Chemical Soc, Washington, 2000)
Temperature effects on the kinetics of formic acid electrooxidation are studied on Pt(111) and on Pt(111) modified by irreversibly adsorbed Bi under both potentiodynamic and potentiostatic conditions. We propose two modes ...
Evaluating a primary healthcare centre's preparedness for disasters using the hospital safety index: Lessons learned from the 2014 floods in Obrenovac, Serbia
(Elsevier Ltd, 2019)
Various organizations have endeavored to develop assessment methods for the identification and management of weaknesses in hospital disaster preparedness. Although the largest number of patients receive their regular care ...
Synthesis and characterization of Pt nanocatalyst on Ru0.7Ti0.3O2 support as a cathode for fuel cells application
(Elsevier Science Sa, Lausanne, 2015)
Ruthenium oxide/titanium oxide, with a Ru:Ti atomic ratio of 7:3 was synthesized by modified sol-gel procedure and used as a support for platinum nanocatalyst for oxygen reduction reaction. The synthesized materials were ...
The polymerisation kinetics of lower dialkyl itaconates
(Wiley-VCH Verlag Gmbh, Weinheim, 1999)
The free radical polymerisation kinetics of diethyl- (DEI), dipropyl- (DnPI), dibutyl- (DnBI), and dihexyl itaconate (DHI) in the bulk were studied in the temperature range from 50 to 70 degrees C. The concentration of the ...
The non-oxidative thermal degradation of poly(di-n-alkyl itaconates). II. Analysis of the polymer residue
(Elsevier Sci Ltd, Oxford, 2005)
The residues remaining after the thermal degradation of poly(di-n-alkyl itaconates) with ester substituents ranging from methyl to n-octyl were studied. It was found that the thermal stability of the polymers decreased ...
Supercritical carbon dioxide essential oil extraction of Lamiaceae family species: Mathematical modelling on the micro-scale and process optimization
(Pergamon-Elsevier Science Ltd, Oxford, 2005)
In this paper the essential oil supercritical carbon dioxide extraction from leaves of Lamiaceae family species was studied. Recent investigations of Lamiaceae family essential oil storage have shown that most of the oil ...
Experimental design approach in the synthesis of hydroxyapatite by neutralization method
(Elsevier, Amsterdam, 2005)
Physicochemical properties of hydroxyapatite (HAP) synthesized by neutralization method are heavily dependent on the process variables. A Plackett-Burman two-level experimental design was therefore, chosen to screen a large ...
