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 ...
Stable colloidal dispersions of magnetic nanoparticles in aqueous media and polymer melts
(2009)
The work presented as part of this thesis describes a process to obtain two types of conventionally used magnetic nanoparticles, magnetite and cobalt ferrite, with a narrow size distribution that can be suspended in aqueous ...
Synthesis of multifunctional magnetic nanoparticles for biomedical applications
(2009)
Magnetite nanoparticles are attractive for biomedical applications such as magnetic fluid hyperthermia (MFH), a novel cancer treatment, due to their ability to induce heating through energy dissipation in an oscillating ...
Towards the design of highly selective molecularly imprinted hydrogels for biosensor applications
(2009)
Robust molecular recognition is essential to enhance the accuracy of diagnostic devices aiming for a better efficacy in the clinical treatment of patients. The molecular imprinting technique has gained attention to generate ...
Maxwell-Stefan modeling of mass transfer effects in reactive chromatography
(2009)
A rigorous dynamic theoretical model was developed and implemented for simultaneous diffusion, reaction, and adsorption inside porous solids for the fixed bed chromatographic reactor (FBCR), true moving bed chromatographic ...
