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 ...
Studies of ferrite based magnetic nanoparticle uptake and magnetocytolysis effects on model cell cultures
(2009)
Suspended ferrite magnetic nanoparticles are known to dissipate energy under an oscillating magnetic field. Such energy dissipation could be employed to locally raise temperature inside a tumor to 41-45°C (hyperthermia), ...
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 ...
Simulations of the magnetization and magnetoviscosity of dilute magnetic fluids
(2009)
In this work was studied the rotational Brownian motion of magnetic spherical and tri-axial ellipsoidal particles suspended in a Newtonian fluid, in the dilute suspension limit, under applied shear and magnetic fields by ...
In situ diffraction studies of Ni nanostructure growth using microporous materials as supports
(2009)
Our objective is to study the growth mechanism of Ni nanostructures supported in microporous materials using X-ray diffraction. Since only the surface atoms of a catalyst are active, our aim is to find the optimum synthesis ...
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) ...
