  1. (A) (B) COLLABORATIVE/FRG RESEARCH: NANO-STRUCTURED MATERIALS OF COVALENTLY BONDED NETWORKS Raj N. Singh and P. Boolchand University of Cincinnati (UC) DMR-0200839 Objective:The primary scientific objective of the focussed research group (FRG) project is to synthesize unusual materials for the emerging nanotechnology such as nanowires and nanotubes based on B, C, and N elements for possible use in hydrogen storage and nanoelectronics. A successful demonstration of this objective is expected to lead to hydrogen-based fuel cells and smaller and more efficient electronics. Results:Our research during this year synthesized novel nanotubular materials using the microwave plasma enhanced chemical vapor deposition (MPECVD) technique. Nanorods of Boron were synthesized on ZrB2 powders using this approach and were characterized by several advanced characterization techniques. Ability of the B-nanorods for hydrogen storage and electrical properties will be explored for possible use in hydrogen storage, electronics, sensors, and biological systems. (A) Synthesis of Boron-nanorods on ZrB2 particles on Si wafers by microwave plasma enhanced CVD, and (B) HRTEM images from the nanorods showing the structure.

  2. COLLABORATIVE/FRG RESEARCH: NANO-STRUCTURED MATERIALS OF COVALENTLY BONDED NETWORKS Raj N. Singh and P. Boolchand University of Cincinnati (UC) DMR-0200839 Education and Outreach Two graduate students, an undergraduate student, and a research associate contributed to this project. One of the graduate students and research associate worked on the synthesis of the films/nanotubes by microwave plasma enhanced chemical vapor deposition technique (MPECVD) and another student worked on the characterization of these films/nanotubes using Raman Spectroscopy and X-ray diffraction techniques. These students will attend the Annual Meeting of the American Ceramic Society in Cincinnati in 2006 to present a paper, learn from other researchers in this field, and broaden their professional outlook. An undergraduate student did his senior project on the synthesis of nanostructured thin films using MPECVD technique. Our facility on MPECVD is toured by prospective high school students and parents of our department on a weekly basis, and other visitors to college of engineering. A female undergraduate chemical engineering student also worked with us as a part of the WISE (Women In Science and Engineering) Program at UC on the synthesis of materials using MPECVD.
