Reaction microkinetic model of xylose dehydration to furfural over beta zeolite catalyst
(Springer Science and Business Media Deutschland GmbH, 2023)
In recent decades, there has been a growing interest in bio-refineries as a crucial element in transitioning to a low-carbon economy. One specific aspect of this interest is the conversion of carbohydrates into separate ...
The nucleation behavior of k2o center dot tio2 center dot 3geo(2) undercooled melt
(University of Chemistry and Technology, Prague, 2009)
The nucleation of K2TiGe3O9 crystals in an undercooled melt of stoichiometric composition was studied. Volume nucleation with spherical morphology of the growing crystals was determined. The nucleation range is in the ...
The study of corrosion stability of organic epoxy protective coatings on aluminium and modified aluminium surfaces
(Soc Brasileira Quimica, Sao Paulo, 2005)
Epoxy coatings were formed by cathodic electrodeposition of an epoxy resin on aluminium and modified aluminium surfaces (phosphatized, chromatized-phosphatized and anodized aluminium) using a constant voltage method (resin ...
Characterization of natural isolate Lactobacillus acidophilus BGRA43 useful for acidophilus milk production
(Wiley, Hoboken, 1998)
Lactobacillus acidophilus BGRA43 was selected from a set of human origin isolates of Lact. acidophilus strains for the highest growth rates and antagonistic effect against both Gram-positive and Gram-negative bacteria. The ...
In Vivo Performance of Fenofibrate Formulated With Ordered Mesoporous Silica Versus 2-Marketed Formulations: A Comparative Bioavailability Study in Beagle Dogs
(Wiley-Blackwell, Hoboken, 2016)
The present study aims to evaluate the in vitro and in vivo performance of ordered mesoporous silica (OMS) as a carrier for the poorly water-soluble compound fenofibrate. Fenofibrate was loaded into OMS via incipient wetness ...
Densities, viscosities, and surface and interfacial tensions of the ternary mixture water plus ethyl butyrate plus methanol at 303.15
(Amer Chemical Soc, Washington, 2003)
The excess molar volumes, V-E, viscosity deviations, Deltaeta, and excess surface tensions were calculated from the measured density, viscosity, and surface tension values, a, over the whole miscibility composition range ...
Surface characteristics and antibacterial activity of a silver-doped carbon monolith
(Natl Inst Materials Science, Ibaraki, 2008)
A carbon monolith with a silver coating was prepared and its antimicrobial behaviour in a flow system was examined. The functional groups on the surface of the carbon monolith were determined by temperature-programmed ...
A Kinetic Study of Candida rugosa Lipase-Catalyzed Synthesis of 4,6-Dimethyl-3-cyano-2-pyridone
(Sociedade Brasileira de Química, 2010)
The synthesis of 4,6-dimethyl-3-cyano-2-pyridone was studied in a reaction catalyzed with Candida rugosa lipase. A response surface methodology (RSM) was applied for the optimization of the experimental conditions. The ...
Crystallization kinetics of K2O·TiO2· 3GeO2 glass studied by DTA
(International Institute for the Science of Sintering, 2008)
Crystallization kinetics of K2O·TiO2· 3GeO2 glass was investigated by differential thermal analysis (DTA). Experiments were performed on powder samples with a particle size < 0.037 mm. The glass samples were heated at ...
Evaluating the microbial diversity of an in vitro model of the human large intestine by phylogenetic microarray analysis
(Microbiology Soc, London, 2010)
A high-density phylogenetic microarray targeting small subunit rRNA (SSU rRNA) sequences of over 1000 microbial phylotypes of the human gastrointestinal tract, the HITChip, was used to assess the impact of faecal inoculum ...
