Determination of an empirical correlation for the mass transfer coefficients of pharmaceutical powders in a fluid bed layer
(2004)
The pharmaceutical industry has four basic operations to produce tablets: mixing, drying,
milling, and tablet pressing. Fluidized bed drying of the pharmaceutical powders is one of
the most efficient methods, which is ...
Characterization of solid dispersions of hydroxypropyl cellulose films with griseofulvin via hot-melt extrusion
(2012)
Hot-melt extrusion has gained significance in the pharmaceutical industry to formulate solid dispersions. In a solid dispersion, poorly-water soluble drugs can be dispersed in an inert hydrophilic polymer matrix, improving ...
Rheological characterization of pharmaceutical gel formulations
(2010)
The aim of this research work was to study the rheological properties of an industrially relevant gelatin-based pharmaceutical formulation, since the rheology of the product provides
information regarding the structure ...
Mixing of granular materials in an oscillatory shear mixer
(2009)
Mezclado es uno de los pasos más importantes en el manejo de los polvos en muchas industrias tales como en la industria química, metalúrgica, farmacéutica, alimenticia, etc., debido al gran efecto que tiene en la composición ...
Structure and rheology of colloid-in-liquid crystal composites with novel anisotropic and hierarchical microstructures
(2015)
The Green's functions integral technique is used to determine the conduction heat transfer temperature field in flat plates, circular plates, and solid spheres with saw tooth heat generating sources. In all cases the ...
Blend uniformity and powder phenomena inside the continuous tumble mixer using experiments and DEM simulations
(2014)
The pharmaceutical industry is in the middle of a major transition regarding manufacturing where continuous operation is a central topic. One of these operations is powder mixing, which could arguably be the principal ...
Development of filtration/biotreatment schemes to recycle CMP wastewater
(2009)
Environmentally benign processing is a concept geared towards reducing the release of pollutants into the environment while maximizing the industrial recyclables. It has been demonstrated that effluents, especially at the ...
Kinetics and modeling of batch bioethanol production using suspended co-cultures of Saccharomyces cerevisiae and Pichia stipitis in glucose-xylose media
(2010)
A mathematical structured model was developed to predict the behavior of glucosexylose mixtures using the suspended co-culture of the wild-type yeast strains Saccharomyces cerevisiae Montrachet and Pichia stipitis NRRL ...
Carboxymethylation of dextran for surface modification of magnetite nanoparticles
(2009)
Magnetite nanoparticles are currently studied for biomedical applications such as MRI, drug delivery, and magnetic fluid hyperthermia (MHF). These applications require nanoparticles with a suitable coating which provides ...
Silicoaluminophosphate nanoporous materials for carbon dioxide adsorption at low concentration
(2011)
The incorporation of extraframework Sr2+ and Ba2+ cations onto silicoaluminophosphate (SAPO-34) zeolitic materials has been proven to influence their adsorptive properties. In this study, three approaches were employed to ...
