Deposition Control for Electrospun Fibers (Electrical Project)

Electrospinning (ES) is a process for fabricating polymer fibers that have diameters that range from tens of nanons to hundreds of microns, which has been studied for over 100 years. These fibers have been studied in applications such as: the enhancement of mechanical properties including increased sensor sensitivity and increased tensile strength, filtration enhancement, drug delivery systems, and as a […]

Creation of Carbon Nanotube Based BioSensors through Dielectrophoretic Assembly (Electronics Project)

Due to their excellent electrical, optical, and mechanical properties, nano-sized single wall carbon nano-tubes (SWNTs) have attracted significant attention as a transducing element in nano-bio sensor research. Controlled assembly, device fabrication, and bio-functionalization of the SWNTs are crucial in creating the sensors. In this study, working biosensor platforms were created using dielectrophoretic assembly of single wall carbon nanotubes (SWNTs) as […]

Analysis of fluctuations in Semiconductor Devices (Electronics Project)

The random nature of ion implantation and diffusion processes as well as inevitable tolerances in fabrication result in random fluctuations of doping concentrations and oxide thickness in semiconductor devices. These fluctuations are especially pronounced in ultrasmall (nanoscale) semiconductor devices when the spatial scale of doping and oxide thickness variations become comparable with the geometric dimensions of devices. In the project, […]

A review on Energy Harvesting from Roads (Electronics/Mechanical Project)

Harvesting Energy stands alone as one of the most promising techniques for approaching the global energy problem without depleting natural resources. Energy harvesting technologies from road infrastructure is a new research territory that encompasses technologies that capture the wasted energy occurred at pavements, accumulate and store it for later use. Their most enticing characteristic is that they already offer extended […]

Novel Micromechanical Bulk Acoustic Wave Resonator Sensing Concepts for Advanced Atomic Force Microscopy (Electrical/Electronics Project)

This study investigates novel concepts of micromechanical bulk acoustic wave sensors for advanced atomic force microscopy (AFM), using micromachined silicon resonators, which are analyzed with regard to their performance as compared to conventional AFM sensors. Conventional AFM systems use a cantilever resonator for sensing the surface forces of the sample. Since a laser is used to detect the cantilevers movement, […]
