We are attempting to develop an atomic layer epitaxy scheme for the deposition of diamond thin films based on the use of halogenated reagents. To this end, we have been investigating the surface chemistry of diamond and graphite substrates with both fluorine and chlorine atoms. We have discovered, using ultrahigh vacuum surface analysis techniques (x-ray photoelectron spectroscopy (XPS) and low energy electron diffraction), that halogen beam dosing of diamond surfaces ...
Aerodyne Products Corp. successfully met the objective of this program, by the development of a device for measurement of fuel leaks in aircraft. This device satisfies the two requirements: (1) monitor enclosed bays for fuel leaks, and (2) measure the fuel leak rate after determining that a leak has occurred. The first application requires a rugged, reliable and inexpensive device that can be mounted in aircraft bays and; continuously monitor ...
