Oil accumulation via Chlorella species using carbon sources from waste
(2009-12)
One of the global issues acquiring significant attention these days is related to energy supply and demand. The irreversible decrease of fossil fuels left to supply energy and the greenhouse gases increase in the atmosphere ...
Carboxymethylation of dextran for surface modification of magnetite nanoparticles
(2009)
Magnetite nanoparticles are currently studied for biomedical applications such as MRI, drug delivery, and magnetic fluid hyperthermia (MHF). These applications require nanoparticles with a suitable coating which provides ...
Synthesis and characterization of Sulfonated Poly(Styrene-Isoprene-Styrene): Effects of linear vs branched morphology and counter-ion substitution
(2009)
This investigation studied the resulting nanostructure of ionic membranes composed of sulfonated copolymers with thermoplastic and elastomeric blocks. Linear poly(styrene-isoprenestyrene) (L-SIS) and branched poly(styren ...
Synthesis and characterization of cobalt-substituted ferrite nanoparticles using reverse micelles
(2005-09)
With the objective of developing a magnetic nanoparticle based sensor, we have
synthesized cobalt-substituted ferrite particles using reverse micelles. Reverse micelles
have been used to control the nanoparticle size. ...
Optimization of a fluid bed dryer by the implementation of a model predictive controller
(2006)
Optimization of the drying operation requires a model containing the operating variables for fluid bed dryers (FBD). Modeling of FBD is still uncertain since the drying process is unpredictable and relies on empirical ...
Modeling and control of continuous tumble mixing of granular materials
(2005-06)
An approach to automatic control of a continuous tumble mixer of powders is presented. The control system is based on an ideal model that describes the mixer dynamics where the controlled variables are the outlet flow from ...
Synthesis and agglomeration of gold nanoparticles in reverse micelles
(2005)
Reverse micelles prepared in the system water, sodium bis-(2-ethylhexyl)
sulfoccinate (AOT), and isooctane were investigated as a templating system for the
production of gold nanoparticles from the reduction of Au (III) ...
Immobilization of myoglobin from horse skeletal muscle (Mb) and hemoglobin (Hb1) from Lucina pectinata in hydrophilic polymer networks for H2S biosensor application
(2005)
Hemeproteins are known for their spectroscopic properties which change during
the binding of specific ligands. This project envisioned the immobilization of myoglobin
from horse skeletal muscle (Mb) and hemoglobin I from ...
Autothermal reforming (ATR) for fuel cells in automotive applications
(2004)
Autothermal reforming of liquid fuels had been demonstrated to be feasible for use in fuel cell vehicles. One of the main problems with reforming systems is that the concentration product of carbon monoxide has to be less ...
Characterization of proton exchange membrane fuel cell and PEM electrolyzer using non-steady electrochemical techniques.
(2004)
Proton Exchange Membrane Fuel Cells (PEMFCs) and PEM Electrolyzer were
characterized using Electrochemical Impedance Spectroscopy (EIS). Faradaic resistance
(RΩ), kinetic and mass transfer parameters such as charge ...
