Interplay of micro-scale flow and fluid micro/nanostructure: Solutions of DNA and suspensions of single walled carbon nanotubes
The dynamics of dilute solutions of DNA flowing in a scaled clown roll-knife free surface coating flow are investigated on multiple scales. The flow is generated between a rotating roll and a stationary glass knife. Extension ...
Development of nanostructured membranes for environmental applications
Two new methods for the fabrication of porous membranes were studied. Ceramic membranes were obtained from alumoxane and ferroxane nanoparticles casted onto porous support materials. The synthesis of ferroxane nanoparticles ...
Performance of nanostructured metal oxane derived ceramic membranes for fuel cell applications
An iron-based ceramic material is shown to be a practical candidate as an electrolyte material for proton exchange membrane in fuel cells. These membranes have comparable conductivity to the NafionRTM membrane with the ...
Phase transitions and diffusion of colloid-polymer systems and thin ferroelectric films for device applications
This thesis is divided into two independent parts: the first part deals with the phase transitions and diffusion of colloid-polymer systems, while the second part concerns the growth of thin ferroelectric films, their ...
