Carbon nanotubes with their attractive properties, one-dimensional character, and their large aspect ratio are ideal candidates for a variety of applications including energy storage, sensing, nanoelectronics, among others. We have studied the growth of carbon nanotubes on copper substrates using a nickel thin film as a catalyst. The catalyst was sputtered in a chamber having a base pressure in the ultra-high-vacuum regime. By adjusting the sputtering parameters, the effects of the morphology and the thickness of the nickel catalyst on the growth of carbon nanotubes have also been investigated. Multiple hydrocarbon sources as carbon feedstock (methane, acetylene and xylene) and corresponding catalyst precursors and varying temperature conditions were used during the Chemical Vapor Deposition (CVD) process to understand and best determine the ideal conditions for carbon nanotube growth on copper. Correlation between the thickness of the thin film nickel catalyst and the carbon nanotube diameter is also presented in the study. Characterization techniques used to study the morphology of the CNTs grown on copper include SEM, TEM and HRTEM, Raman Spectroscopy(Received November 19 2009)(Accepted February 15 2010)

Physical vapor deposited nickel catalyst layers of 10, 50, 100, 200, 350, and 500 angstroms were granulated using hydrogen plasma for varying times to determine an effective carbon nanotube (CNT) growth process using microwave plasma enhanced CVD (MPECVD). Nickel was deposited via sputtering or evaporation. The catalyst granule size, density, and resulting CNTs were analyzed. Sputtered nickel of 50 angstroms

Ibadi Muslims, a minority religious community, historically inhabited pockets throughout North Africa, the Arabian Peninsula, and the East African coast. Yet less is known about the community of Ibadi Muslims that relocated to Egypt. Focusing on the history of an Ibadi-run trade depot, school and library that operated in Cairo for over three hundred years, this book shows how the Ibadi Muslims operated in and adapted to the legal, religious, commercial, and political realms of the Ottoman Empire from the seventeenth to early twentieth centuries. Using a unique range of sources, including manuscript notes, family histories and archival correspondence, Paul M. Love, Jr. presents an original history of this Muslim minority told from the bottom up. Whilst illuminating the events that shaped the history of Egypt during these centuries, he also brings to life the lived reality of a Muslim minority community in the Ottoman world.
