Electrical Characterization Of Nanomaterials, Chase Martin Jun 2015

Electrical Characterization Of Nanomaterials, Chase Martin

Honors Theses

Our dependence on energy sources and depleting fossil fuel reserves are forcing the world to look for efficient and renewable sources of energy. Current renewable technology lacks the efficiency and storage capability necessary to continue our heavy reliance on energy. This project focuses on understanding the physical and electrical properties of nanomaterials for their use as super capacitors and as photovoltaic cells. Using multiple microscopy techniques on the Cascade Probe Station and Veeco Dimension V Atomic Force Microscope, local and bulk conductivity measurements were performed on Laponite RD infused polyaniline (PANI) samples synthesized by Union College Chemistry Department Students. Four …


Design, Application, And Power Performance Analyses Of A Micro Wind Turbine, Hayati̇ Mamur Jan 2015

Design, Application, And Power Performance Analyses Of A Micro Wind Turbine, Hayati̇ Mamur

Turkish Journal of Electrical Engineering and Computer Sciences

In this study, design, implementation, and power performance analyses of a micro wind turbine (MWT) system are presented. An original permanent magnet synchronous generator (PMSG) that reduced cogging torque was employed as a generator in the MWT. A novel blade form offering better performance at low wind speeds was also utilized for the MWT blades. Power performance analyses of the MWT were carried out for different wind regimes by truck testing. Performance coefficient, cut-in, and cut-out of the MWT were determined as 27.7{\%}, 2.7 m/s, and 20 m/s at the end of the truck testing, respectively. Moreover, a new supervisory …
