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 ...
Solubilities of anti-cancer and anti-AIDS drugs in supercritical carbon dioxide
(2003)
Solubility data for pharmacological drugs in supercritical fluids (SCFs) is of great
importance, because there is an environmental and cost effective need for alternative
specialty separation methods.
This research was ...
Separational purification of nitrate from inedible biomass leachate by electrodialysis: fouling effect
(2004)
The removal of nitrate and potassium from wheat leachate solution was studied
using an electrolytic cell in batch recirculation mode for use in advance life
support systems (ALSS). The ALSS or CELSS (Controlled Ecological ...
Effects of environmental parameters on the chemical signature of landmines
(2005)
The presence of buried landmines is an environmental problem in many parts of the
world; strategies to detect and remove landmines are being developed; one of these
strategies is the developing of chemical based sensors. ...
Optimization of drying-end-points measurements for the automation of a fluidized-bed dryer using FT-NIR sprectroscopy
(2004)
Automatic control of a fluidized-bed drying process depends on the availability of
an in-line sensor to provide accurate measurements of product moisture content. Nearinfrared
(NIR) spectroscopy technology provides a ...
Sonolysis of pharmaceutical and personal care products as an advanced oxidation process for the remediation treatment of wastewater effluents
(2007)
Pharmaceutical and Personal Care Products (PPCPs) are a diverse group of chemicals, also known as xenobiotics, treated like potential environmental pollutants. Recently, PPCPs have been detected in trace amounts in surface ...
Novel separation methods for removing nanoparticles and copper from chemical mechanical planarization wastes
(2007)
Chemical mechanical planarization (CMP) wastewater emanating from semiconductor processing contains copper (II) ions and either alumina and/or silica nanoparticles. The efficiency of biotreatment schemes to remove copper ...
