Effect of different radiopacifying agents on the physicochemical properties of white portland cement and white mineral trioxide aggregate
(2012-03-01)
Introduction: The aim of this study was to evaluate the pH, calcium ion release, setting time, and solubility of white mineral trioxide aggregate (WMTA) and white Portland cement (WPC) combined with the following radiopacifying ...

Microstructure-extractability relationships in the extraction of prepelletized Jalapeno peppers with supercritical carbon dioxide
(WILEY, 2005)
There is a need to increase vessel loads for high-pressure batch processes such as supercritical fluid extraction of solid substrates, but a precompacting treatment such as pelletization may negatively affect mass transfer ...
Microstructural effects on internal mass transfer of lipids in prepressed and flaked vegetable substrates
(ELSEVIER, 2006)
Predictive models that describe supercritical fluid extraction (SCFE) processes would be welcomed to support its industrial application, particularly for the supercritical carbon dioxide (SC-CO2) extraction of vegetable ...

Gas sorption, permeation and separation of ABS copolymer membrane
(Elsevier Science, 2003-08-15)
This work examines the gas transport and sorption properties of a commercial acrylonitrile-butadiene-styrene (ABS) copolymer (Lustran®246), containing 60% styrene, 27% acrylonitrile and 13% butadiene. Permeability, diffusion ...
Supercritical CO2 processing of pretreated rosehip seeds: effect of process scale on oil extraction kinetics
(ELSEVIER SCIENCE BV, 2004)
Rosehip oil was extracted from milled seeds with supercritical carbon dioxide (SC-CO2). The effects of sample pretreatment and interstitial solvent velocity (0.40-2.45 mm/s) on kinetics of extraction (oil yield versus time) ...
