Investigation of PACVD protective coating processes using advanced diagnostics techniques

Description: Coherent anti-Stokes Raman Spectroscopy (CARS) is used to study the plasma-assisted chemical vapor deposition (PACVD) of TiB{sub 2}. CARS is applied to the dominent species in an inductively coupled B{sub 2}H{sub 6}/Ar rf plasma. Axial concentration profiles of diborane and hydrogen are probed in the plasma. A five-step mechanism is developed. Photochemical initiation of the chemical reaction is considered. 16 refs, 5 figs.(DLC)

Nuclear studies with intermediate energy probes. [Dept. of Physics, Univ. of Virginia]

Description: Data from measurements at NIKHEF-K of the electro-production of neutral pions from the proton were completely analyzed and axe about to be submitted for publication. These results represent the first precise measurement of this fundamental process in the threshold region. The results are completely consistent with calculations based upon the Low Energy Theorems. Results from studies of a gas jet target in the electron storage ring of the Saskatchewan Accelerator Laboratory (SAL) have been fully… more

Increased IMP dehydrogenase gene expression in solid tumor tissues and tumor cell lines

Description: IMP dehydrogenase, a regulatory enzyme of guanine nucleotide biosynthesis, may play a role in cell proliferation and malignancy. To assess this possibility, we examined IMP dehydrogenase expression in a series of human solid tumor tissues and tumor cell lines in comparison with their normal counterparts. Increased IMP dehydrogenase gene expression was observed in brain tumors relative to normal brain tissue and in sarcoma cells relative to normal fibroblasts. Similarly, in several B- and T-lymp… more

Chemical and thermal stability of refrigerant-lubricant mixtures with metals

Description: This report presents completed sealed tube stability test results for the following eight refrigerant/lubricant mixtures: R-22/mineral oil; R-124/alkylbenzene; R-134a/pentaerythritol (PE) ester (mixed acid); R- 134a/PE (branched acid); R-134a/ PE (100 cSt viscosity); R- 142b/alkylbenzene; R-143a/ PE (branched acid); R-152a/alkylbenzene. Partial results are shown for an additional eight refrigerant-lubricant mixtures. Though work is in progress, no data are available at this point in time for th… more

Development and testing of industrial scale, coal fired combustion system, Phase 3. Second quarterly technical progress report, April 1, 1992--June 30, 1992

Description: In the second quarter of calendar year 1992, work continued on Task 1.1. ``DESIGN MODIFICATIONS TO THE 20 MMBTU/HR AIR COOLED COMBUSTOR AND BOILER COMPONENTS``. This consisted of specifying and designing the changes needed to prepare the 20 MMBtu/hr air cooled combustor at the Tampella boiler house site in Williamsport, PA. In depth review of the technical status of the combustor showed that no major design changes were necessary in order to implement the effort of task 2 testing and part of th… more

Colloids in Groundwater: Their mobilization, subsurface transport, and sorption affinity for toxic chemicals

Description: Our originally stated objectives included: (1) development of a quantitative source function for colloid mobilization to groundwater, and (2) assessment of the most important colloidal phases to which nonpolar compounds sorb. We have been pursuing a series of studies to elucidate the roles of colloidal phases in subsurface environments. Most notably, we have discovered the critical role of secondary cementitious phases like goethite. We developed a new procedure for measuring surface iron oxide… more

Resonance ionization spectroscopy of molecules, clusters, and ions. Continuation proposal and annual technical progress report

Description: Supersonic beam studies of the dimer of the aromatic molecule fluorene reveal both excitonic and excimer properties. The high resolution spectra obtained for the cold clusters suggests that it will be possible to elucidate the coupling between these types of states. The accumulating evidence indicates that both types of states occur generally for aromatic clusters. Their relative contributions to the spectra are not currently understood. This problem is the emphasis of the ongoing investigation… more
