Improvement of the mechanical properties of spark plasma sintered hap bioceramics by decreasing the grain size and by adding multi-walled carbon nanotubes
(International Institute for the Science of Sintering, Beograd, 2013)
Composites based on HAP and oxidized multi-walled carbon nanotubes (o-MWCNT) and monophase HAP materials were processed by spark plasma sintering. Starting from stoichiometric nano-sized HAP powder, monophase bioceramics ...
Solidification of High Chromium White Cast Iron Alloyed with Vanadium
(Japan Inst Metals, Sendai, 2011)
Experimental results indicate that vanadium affects the solidification process in high chromium iron. Vanadium is distributed between eutectic M7C3 carbide and the matrix, but its content in carbide is considerably higher. ...
Thermal shock damage characterization of high temperature ceramics by non destructive test methods
(University of Chemistry and Technology, Prague, 2008)
In the present work a mixture of commercially available spinel, quartz (SiO2) and alumina (Al2O3) corresponding to cordierite stoichiometry was used as starting material for obtaining cordierite/SiC composite ceramics with ...
Development of a microbiosensor based on fish Chromatophores immobilized on ferromagnetic gelatin beads
(University of Zagreb, 2005)
Development of a microbiosensor based on immobilized living chromatophores of Siamese fighting fish, Betta splendens, for the detection of microbial and environmental toxins is described in this paper. Chromatophores were ...
Synthesis, characterization and biological activity of 2-(5-arylidene-2,4-dioxotetrahydrothiazole-3-yl) propanoic acid derivatives
(Elsevier Science Bv, Amsterdam, 2017)
A series of six novel 2-(5-arylidene-2,4-dioxotetrahydrothiazole-3-yl) propanoic acids and six corresponding methyl esters were synthesized. All compounds were characterized by melting points, elemental analysis, FT-IR, ...
Lipase-Catalyzed Synthesis of Ascorbyl Oleate in Acetone: Optimization of Reaction Conditions and Lipase Reusability
(Japan Oil Chemists Soc, Tokyo, 2013)
Lipase-catalyzed ascorbyl oleate synthesis is eco-friendly and selective way of production of liposoluble biocompatible antioxidants, but still not present on an industrial level due to the high biocatalyst costs. In this ...
Synthesis, structure and solvatochromic properties of some novel 5-arylazo-6-hydroxy-4-phenyl-3-cyano-2-pyridone dyes
(Springeropen, London, 2012)
Background: A series of some novel arylazo pyridone dyes was synthesized from the corresponding diazonium salt and 6-hydroxy-4-phenyl-3-cyano-2-pyridone using a classical reaction for the synthesis of the azo compounds. ...
Chemical and Antimicrobial Evaluation of Supercritical and Conventional Sideritis scardica Griseb., Lamiaceae Extracts
(MDPI, Basel, 2012)
Sideritis scardica Griseb., Lamiaceae (ironwort, mountain tea), an endemic plant of the Balkan Peninsula, has been used in traditional medicine in the treatment of antimicrobial infections, gastrointestinal complaints, ...
Electrochemically deposited nano fibrous polyanilne for amperometric determination of glucose
(Inst Materials Physics, Bucharest, 2012)
Electrochemical deposition of polyaniline (PANI) on graphite electrode was performed galvanostaticaly at constant current density in the range of 1.0 - 5.0 mA cm(-2) from aqueous acidic electrolyte containing aniline ...
The use of image analysis for determination of surface deterioration level of improved alumina based materials subjected to cavitation
(International Institute for the Science of Sintering, Beograd, 2013)
Alumina based specimens having different content of alumina based fibers were investigated for possible application as cavitation resistant material. Cavitation damages of the alumina based specimens were tested by the ...
