Characterization and Reactivity of Mo₂C
Two types of Mo₂C have been investigated: polycrystalline β-Mo₂C and single crystal α-Mo₂C. The β-Mo₂C material was synthesized via a temperature-programmed method, and then characterized using x-ray diffraction (XRD), x-ray photoelectron spectroscopy (XPS), CO chemisorption, and N₂ physisorption. …

Thermal expansion behavior of Mo-Si-B system intermetallics
<p>Currently, industrial, automotive, and aerospace areas have a need for structural materials that can withstand oxidizing and aggressive environments at temperatures above 1000 0C. Mo-Si-B system intermetallics have been attracting attention as promising candidate materials for such applications, …

Preparation and characterization of Mo/Al layered thin films
The fabrication of bilayer and multilayer Mo/Al thin films using a conventional multi-target rf-diode sputter deposition system was studied. The films were deposited on glass and Si( 100) substrates. The as-deposited films were characterized with respect to their structure and composition profiles …

Reductive coupling and related reactions with Mo and Ti tris- anilides
Chapter 1: The capability of Mo(N[t-BulAr)₃ to act as a powerful one, two, and three electron reductant have been previously demonstrated. In this work, we show that Mo(NIt-BulAr)₃ forms a metastable adduct with the moderate [pi] acid PhCN; coordination of PhCN activates the nitrile carbon towards …
