AN ASSESSMENT of CARBON and FLUOROCARBON IMPLANTS AS SOFT-TISSUE SPACE FILLERS in RATS
(Excerpta Medica Inc, 1994-01-01)
The physical properties of carbon and fluorocarbon implants and surrounding tissue were assessed and compared over 1 year in rats. the inflammatory and reparative phases were separated and physical properties were tested ...
HYDROTHERMAL REE FLUOROCARBONATE MINERALIZATION AT BARRA DO ITAPIRAPUA, A MULTIPLE STOCKWORK CARBONATITE, SOUTHERN BRAZIL
(MINERALOGICAL ASSOC CANADA, 2008)
The Barra do Itapirapua ( BIT) carbonatites in southern Brazil belong to the final stages of the Early Cretaceous alkaline rock - carbonatite magmatism of the Ponta Grossa Arch Province. The BIT complex is a dyke and vein ...
High-Temperature Fluorocarbon Chemistry Revisited
(American Chemical Society, 2021-07)
The thermal dissociation reactions of C2F4and C2F6were studied in shock waves over the temperature range 1000-4000 K using UV absorption spectroscopy. Absorption cross sections of C2F4, CF2, CF, and C2were derived and ...
Shock wave studies of the pyrolysis of fluorocarbon oxygenates. II. the thermal dissociation of C4F8O
(Royal Society of Chemistry, 2017-04)
The thermal decomposition of octafluorooxalane, C4F8O, to C2F4 + CF2 + COF2 has been studied in shock waves highly diluted in Ar between 1300 and 2200 K. The primary dissociation was shown to be followed by secondary ...
Shock Wave Study of the Thermal Dissociations of C3F6 and c-C3F6. I. Dissociation of Hexafluoropropene
(American Chemical Society, 2014-06)
The thermal dissociation of C3F6 was studied between 1330 and 2210 K in shock waves monitoring the UV absorption of CF2. CF2 yields of about 2.6 per parent C3F6 were obtained at reactant concentrations of 500-1000 ppm in ...
Influence of incorporation of fluoroalkyl methacrylates on roughness and flexural strength of a denture base acrylic resin
(Faculdade De Odontologia De Bauru - USP, 2009)
Fluorinated denture base acrylic resins can present more stable physical properties when compared with conventional polymers. This study evaluated the incorporation of a fluoroalkyl methacrylate (FMA) mixture in a denture ...
Shock Wave Study of the Thermal Dissociations of C3F6 and c-C3F6. II. Dissociation of Hexafluorocyclopropane and Dimerization of CF2
(American Chemical Society, 2014-06)
The thermal dissociation of c-C3F6 has been studied in shock waves over the range 620–1030 K monitoring the UV absorption of CF2. The reaction was studied close to its high-pressure limit, but some high-temperature falloff ...
