Method for determining refractory specimen heat resistance
(Springer, New York, 2008)
The most important properties governing the operation of refractories are refractoriness, service temperature and heat resistance. The heat resistance of specimens based on Al2O3 is determined by a standard laboratory ...
Synthesis and settings behavior of alpha-TCP from calcium deficient hyroxyapatite obtained by hydrothermal method
(Natl Inst Optoelectronics, Bucharest-Magurele, 2007)
The aim of this work is the investigation of alpha-tricalcium-phosphate (alpha-TCP) formation from calcium-deficient hydroxyapatite (CDHAP), synthesized by hydrothermal method from CaCl2, EDTA, NaH2PO4 center dot 2H(2)O ...
Sintering behaviour of nanosized HAP powder
(Trans Tech Publications Ltd, Durnten-Zurich, 2007)
The influences of temperature and time on sintering behaviour of nanosized HAP powder were investigate in this paper. The calcium hydroxyapatite powder, with the average crystallite size of 34 +/- 1 nm, was uniaxially ...
Electrochemical deposition and characterization of Zn-Co alloys and corrosion protection by electrodeposited epoxy coating on Zn-Co alloy
(Pergamon-Elsevier Science Ltd, Oxford, 2002)
Zn-Co alloys electrochemically deposited on steel under various deposition conditions were investigated. The influence of deposition current density, temperature and composition of deposition solution on the phase structure ...
Biocompatible and bioadhesive hydrogels based on 2-hydroxyethyl methacrylate, monofunctional poly(alkylene glycol)s and itaconic acid
(Springer, New York, 2006)
Novel poly(Bisomer/HEMA/IA) hydrogels were prepared by radical copolymerization of poly(alkylene glycol) (meth)acrylates, i.e. short chains Bisomers, 2-hydroxyethyl methacrylate (HEMA) and itaconic acid (IA) in a mixture ...
Zeolite/Chitosan/Gelatin Films: Preparation, SupercriticalCO2Processing, Characterization, and Bioactivity
(Wiley, 2022)
Chitosan/gelatin and chitosan/gelatin/zeolite films prepared by solvent casting method were impregnated with a mixture of thymol and carvacrol using a green solvent, supercritical carbon dioxide at 35 °C and 30 MPa, during ...
Crystallographic, spectroscopic, thermal and computational studies of polymeric cobalt(II)-mellitate complex with 2,2 '-bipyridine

Orange single crystals of new polymeric cobalt(II) complex {[Co(bipy)(H2O)(4)](2)[Co(mu-mell)(H2O)(2)].10H(2)O}(n), 1, were synthesized by slow evaporation method at room temperature (bipy = 2,2 '-bipyridine, mell = hexaanion ...
Supercritical carbon dioxide extraction of sesquiterpenes from valerian root
(Elsevier Science Bv, Amsterdam, 2007)
Supercritical carbon dioxide extraction of sesquiterpenes from valerian root was investigated. Extractions from cultivar Arterner zuctung and two wild grown valerian subspecies were performed. The influence of extraction ...
Hydrogen evolution on Ni/WC composite coatings
(Springer, 2006)
The catalytic activity for the hydrogen evolution reaction (HER) of Ni/WC composites obtained by electrochemicaldeposition of nickel from a conventional Watt’s bath, using two different ways of depositing the WC particles, ...
Utilization of supercritical carbon dioxide for development of antibacterial surgical sutures
(Elsevier B.V., 2022)
Outbreak of surgical infections and bacterial resistance against synthetic antibiotic has prompted research towards development of antibacterial medical devices. For that purpose, absorbable surgical sutures were impregnated ...
