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 ...
Evaluation of NIR, FTIR and Raman spectroscopies as monitoring techniques for recombinant GFP protein production in fed-batch cultures of Escherichia coli
(2008)
The expression of green fluorescent protein (GFP) was induced and monitored in fed-batch cultures of a genetically-engineered Escherichia coli strain. This recombinant E. coli is commercially available (Bio-Rad pGLO kit), ...
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 ...
Testing of centrifugal filter devices as a tool to quantify protein-nanoparticle interactions using UV/Vis measurements
(2012)
Centrifugal Filter Devices (CFD) has been tested for the quantification of protein adsorption onto the surface of magnetic nanoparticles coated with biocompatible polymers. Using a phosphate buffered saline wash protocol, ...
Uso de la técnica de interrupción de corriente para la caracterización de una celda de combustible no humidificada con membrana de intercambio protónico
(2005)
Due to the energetic crisis, the US government has promoted the development of
alternatives resources for the generation of electricity. Fuel Cells have emerged as one of
the most promising technologies for the power ...
Supercritical fluid processing of sulfonated styrenic tri-block polymers
(2005)
The increasing need to replace current materials with new or reprocessed
ones that have more specific properties and uses has led to the use of supercritical
fluids (SCFs) for polymer reprocessing. Kraton® poly ...
