Thermal stability of an alumina-based refractory
(American Ceramic Society Bulletin, 2006)
The thermal stability, dynamic Young's modulus of elasticity, anisotropy and damage level of a 42% alumina refractory material were investigated using a water-quench test. Thermal quenching of refractories leads to crack ...
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
(Elsevier B.V., 2022)
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 ...
Prediction for debonding damage process of glass beads-reinforced modified polyphenylene oxide under simple shear
(Elsevier Science Sa, Lausanne, 2005)
A three-dimensional finite element cell modeling technique has been applied to predict the particle-matrix debonding process of particulate polymer composite (PPC) subject to simple shear loading. The particle-matrix ...
Electrophoretic deposition of boehmite coatings on titanium from aqueous sols
(Trans Tech Publications Ltd, Durnten-Zurich, 2004)
The electrophoretic deposition from sots and colloidal suspensions of ceramic powders has many advantages over conventional ceramic powder processing methods. In this way it is possible to control the thickness and ...
Study on thermal stability of water-based polyurethanes derived from hydroxypropyl terminated poly(dimethylsiloxane)
(Springer Science and Business Media B.V., 2024)
In this paper, thermal and thermo-oxidative stability of three water-based polyurethanes (PUs) derived from hydroxypropyl terminated poly(dimethylsiloxane) (HPT-PDMS) were studied. The structural properties of the synthesized ...
Doped gamma-Bi2O3: synthesis of microcrystalline samples and crystal chemical analysis of structural data
(Walter de Gruyter Gmbh, Berlin, 2007)
A series of microcrystalline products containing the gamma-Bi2O3 phase doped with Co, Fe, Mn, Pb, Sb, Si, Ti, V and Zn has been prepared by solid state reaction. Based on the heating temperature and heating time, the ...
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 ...
Hemp Fibers: Old Fibers - New Applications
(Textiles: History, Properties and Performance and Applications, 2014)
Hemp (Cannabis sativa) was most likely the first plant cultivated by mankind for its textile use. Currently, the interest in hemp is focused on its use as a raw material for the production of environmentally friendly ...
