Synthesis, characterization and detemplation of thermally unstable 3-D Metal-Substituted Aluminophosphates.
(2009)
The extent of the detemplation process in Me-SBE (Me = Co2+, Mg2+ and Mn2+) aluminophosphates was investigated. Hydrothermal synthesis conditions were optimized to obtain materials with minimal phase impurities. SEM analysis ...
Selective nanoporous sorbents for gas based separations: Ion exchanged silicoaluminophosphates and titanosilicates
(2009-05)
Two specific sorbents were targeted in this research work: silicoaluminosphosphates (SAPOs) and titanium silicates. For the former, Na+ -SAPO-34 sorbents were ionexchanged with several cations (Ag+, Mg2+, Ca2+, Sr2+, Ti3+, ...
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 ...
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 ...
Functionalization of inhalable particles by fluidized bed processing
(2008)
This work focused initially on the size reduction of naproxen sodium to less than 5 µm for inhalation applications. The second objective was the adhesion of naproxen sodium particles to micronized lactose particles with ...
Modeling of TNT transport from landmines
(2008)
The transport of Explosive Related Compounds (ERCs) has been studied as part of a research program aiming to the development of chemical sensors for detecting landmines. TNT and its degradation products typically make up ...
