Synthesis and characterization of porous inorganic adsorbents for the removal of PPCPs via complexation and size exclusion principles
(2013)
Pharmaceutical and personal care products (PPCPs) are considered emerging contaminants that present great challenges for their remediation from water systems. Unfortunately, traditional water treatment methods are not ...
Catalytic conversion of CO2 to hydrocarbons
(2014)
The production of methanol and dimethyl ether via CO2 hydrogenation was studied using Pd catalysts supported on α-Ga2O3, α-β-Ga2O3 and β-Ga2O3 polymorphs. The catalytic activity improves with the increase in the content ...
Synthesis and characterization of a novel palladium nanostructured ensemble supported on anodized alumina substrates for hydrogen sensing applications
(2015)
Hydrogen is a versatile molecule used in many industrial processes. Hydrogen is flammable at concentrations between 4% to 75% v/v at atmospheric pressure with a tendency to leak. There are a variety of hydrogen sensors, ...
Use of crosslinked hydrogels for the control of macromolecular crystallization
(2012)
Crosslinked hydrogels in protein crystallization is an area of continuous growth. The counterdiffusion technique is a novel method for the crystallization of proteins, which entails the minimization of convection effects, ...
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 ...
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 ...
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 ...
