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 and characterization of sulfonated amine block copolymer membranes for fuel cells and specialty separations applications
(2021-07-09)
This work focuses on the synthesis and characterization of block copolymers membranes with multi-ionic domains to analyze the effect of the morphological and chemical changes on the transport properties for their use in ...
Pickering liquid crystal emulsions: Influence of mixed-monolayer protected gold nanoparticles on colloidal stability and surfactant-induced ordering transitions
(2021-04-13)
Liquid crystal (LC) droplets dispersed in aqueous phases (e.g., LC-in-water emulsions) provide a versatile platform for the design of droplet-based LC sensors that can respond to the presence of chemical and biological ...
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, ...
CO2 adsorption in nickel based metal organic framework Ni-DABCO: A density functional theory and grand canonical Monte Carlo study
(2018-12-07)
The continuous emissions of greenhouse gases, especially carbon dioxide (CO2), are
generating concerns over the negative effects they are having on the planet. The main goal of this
project is to understand the adsorption ...
Particle flow promoted by external forces in a confined space – feed frame case
(2014)
Pharmaceutical tablets are the most sold and preferred drug solid dosage form due to its many advantages. The feed frame was designed to transfer the powder from the hopper to the tablet press dies as the die disk rotates. ...
An evaluation of optical band gap in photovoltaic polymers for solar energy capture
(2019-05-14)
Organic solar cells are a very promising technology for use in the renewable energy field. Band gap measurements on liquid phase for different polymers were studied, and the possible radiation harvest and reasoning for ...
Novel synthesis and characterization of supported bimetallic films for hydrogen detection
(2014)
Continuous increase in energy demand and high levels of pollution generated by the existing energy sources have led researchers to explore other clean and renewable alternatives. Hydrogen gas (H2) is an option that has ...
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 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) ...
