Effect of impeller speed on particle size distribution during high shear wet granulation process
(2010)
Wet granulation is the process where powders are mixed with a binder agent which is agitated with a mixer and forms a granulated product. This process is commonly used to better the processing characteristics of a powdered ...
Thermogravimetric characterization of polystyrene-based, triblock copolymers: effects of sulfonation, counter-ion substitution, number average molecular weight, and polystyrene weight fraction
(2010)
In this study, poly (styrene-isobutylene-styrene) (SIBS) was characterized using thermogravimetric analysis. The thermal behavior of three types of SIBS, with different average number molecular weight, Mn , and polystyrene ...
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 ...
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 ...
Observation of enhanced Raman scattering as a result of coupling between localized plasmons and surface polariton waves associated with metal-semiconductor nanocomposites
(2011-05)
We report the observation of enhanced Raman scattering as a result of the coupling between the localized surface plasmon (LSP) of metal nanoparticles (NP) and the surface plasmon polariton (SPP) associated with a thin metal ...
Cost analysis of local bioproducts processing plant using microalgae biomass feedstock
(2012)
The need to produce bioproducts useful for the human wealth derived from microalgae, such as proteins, lipid and carbohydrates is gaining importance in recent years. In spite of the broad availability of technologies for ...
Measurement and correlation of axial dispersion coefficient in a bubble column with a non-Newtonian liquid phase
(2006)
Hydrodynamic characteristics (gas holdup, friction factor, and mixing in the liquid
phase) in a bubble column with a non-Newtonian liquid phase (aqueous solutions of
carboxymethylcellulose, or CMC, at different concentrations) ...
Perfluorinated and sulfonated proton exchange membranes: Effect of supercritical fluid processing on ion exchange capacity and proton conductivity
(2007)
The present work has processed Nafion® and sulfonated polystyrene-isobutylenestyrene
(SIBS) with supercritical fluid (SCF) carbon dioxide at a 40°C and 200 bar with
the aid of ten co-solvents of different size and polarity. ...
Hydrogen production study using autothermal reforming of biodiesel and other hydrocarbons for fuel cell applications
(2006)
During the last few years concerns with distribution, supply and cost of conventional liquid fuels increased considerably. Several developed countries are seriously considering using hydrogen (no fossil combustible) as an ...
Assessment of the stability and biological activity of our model proteins encapsulated in hydrogel membranes
(2007)
Proteins are biological macromolecules which have a unique spatial conformation. This spatial conformation can be affected by extremes in pH, temperature, and organic solvents. Once this 3D spatial conformation is affected ...
