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 ...
Magnetorheology in rotating magnetic fields
(2007)
We studied the flow of ferrofluid induced by rotating magnetic fileds. This flow was observed for first time in fi96F by Moskowitz and Rosensweig [App1. Ph4s. Gett., 10, pag. 3Ofi (fi96F)] and since then researchers has ...
Single particle dynamics around the boundaries of nematic media
(2018-10-31)
Brownian motion of a colloid suspended in a lyotropic chromonic liquid crystal (LCLC's) leads to the description of the transport properties of the medium through a unification of theories where the confinement effect is ...
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 ...
CO2 adsorption in nickel based metal organic framework Ni-DABCO: A density functional theory and grand canonical Monte Carlo study
(2018-12-07)
The continuous emissions of greenhouse gases, especially carbon dioxide (CO2), are
generating concerns over the negative effects they are having on the planet. The main goal of this
project is to understand the adsorption ...
Transition metal based complexation materials for the selective adsorption of contaminants of emerging and concern and metabolites from aqueous solutions
(2018)
Since the presence of contaminants of emerging concern (CECs) in different water sources was revealed, the development of more efficient technologies for their removal has been a constant challenge for the scientific ...
