Kinetics and modeling of batch bioethanol production using suspended co-cultures of Saccharomyces cerevisiae and Pichia stipitis in glucose-xylose media
(2010)
A mathematical structured model was developed to predict the behavior of glucosexylose mixtures using the suspended co-culture of the wild-type yeast strains Saccharomyces cerevisiae Montrachet and Pichia stipitis NRRL ...
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 ...
Encapsulation of particles in crosslinked hydrogel networks: particles distribution optimization
(2010)
Particle encapsulation in polymer systems has been used in several industrial applications in the biomedical and pharmaceutical fields. The main challenge in particle encapsulation is to obtain a homogeneous particle ...
Synthesis and characterization of modified mesoporous silicates for the adsorption of pharmaceutical and personal care products
(2011)
PPCPs have been recently identified as emerging contaminants due to their persistence in our potable water supply and aquatic systems. Unfortunately, traditional water treatment methods are inadequate for the removal of ...
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 ...
Magnetorheological characterization of magneto-responsive fluids
(2012)
The work presented in this dissertation focuses primarily on the rheological characterization of magneto-responsive fluids, consisting of suspensions of magnetic nanoparticles in non-magnetic liquid media. The rheology of ...
Novel synthesis and characterization of metal nanometric wires and anodic alumina membrane-palladium wire ensembles using solid state reduction for hydrogen sensing applications
(2012)
In the last decade nanowires (NWs) have become the focus of intensive research in the areas of catalysis, sensors, gas storage, among others. These ordered high surface area materials display high chemical reactivity because ...
Transport properties of proton-exchange membranes: effect of supercritical-fluid processing and chemical functionality
(2010)
Nafion® membranes commonly used in direct methanol fuel cells (DMFC), are tipically limited by high methanol permeability (also known as the cross-over limitation). These membranes have phase segregated sulfonated ionic ...
Effects of apoptotic inhibitor addition to cell viability prolongation of suspended bench-scale CHO culture and analysis of raman spectra in off-line bioreactor samples
(2010)
The productivity of suspended mammalian cell cultures plays a major role in the overall manufacturing costs of biotechnology products. Upstream cell culture product variability can lead to problems in downstream purification ...
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 ...
