The use of infrared kinetic spectroscopy to study small free radicals
(1998)
The technique of infrared kinetic spectroscopy has been used to study the reaction of the propargyl radical (C3H3) with nitric oxide (NO). The overall rate constant at the high pressure limit for the reaction was determined ...
Synthesis, characterization and magnetic property studies of copper-based phosphate and silicate compounds containing nanosize transition metal oxide frameworks
(1996)
The search for novel compounds with nanosize transition metal oxide frameworks is important for the study and understanding of materials with interesting and important magnetic and electronic properties. These low-dimensional ...
Use of endohedral metallofullerenes for nuclear medicine applications
(1998)
The metallofullerenes, Hox C82 (x = 1,2) and Gd C 82 were generated, sublimed from carbon-arc soot, and further purified by HPLC. Sample purity was then judged by LD-TOF MS and compared with purities obtained by ICP-AE and ...
Compact gas sensors based on mid-infrared frequency conversion of semiconductor lasers
(1997)
Design, development, and application of novel all-solid-state spectroscopic gas sensors is reported. These compact instruments employ mid-infrared difference-frequency generation pumped by room-temperature semiconductor ...
Photoelectron spectroscopy of negative cobalt clusters: Correlation of promotion energy to reactivity
(1992)
Photoelectron spectra of negatively charged cobalt clusters in the size range of 4-26 atoms have been obtained. The electron affinity (E.A.) values along with the reported ionization potential (I.P.) have been used to ...
Towards a fullerene-based nanotechnology: The (10,10) tube
(1997)
While fullerenes form in yields exceeding 30% by mass when a laser generated pure carbon vapor is allowed to condense under annealing conditions, more than 70% of all vaporized carbon assembles in the form of single-wall ...
Investigations of CVD diamond-growth mechanisms using computer techniques: A. Equilibrium calculation program TEQWORKS. B. Molecular mechanism program MM3
(1993)
Equilibrium concentrations of the major species in conventional and halogen assisted CVD diamond synthesis systems were calculated and the results are presented in this thesis. The optimal diamond deposition conditions ...
FT-ICR studies of gas phase silicon cluster ion reactivity and a new model for predicting the structure of silicon clusters
(1990)
A new apparatus capable of combining an external laser vaporization supersonic cluster beam source with a Fourier transform ion cyclotron resonance (FT-ICR) mass spectrometer has been designed and implemented. Cluster ions ...
Kinetics and morphology of homoepitaxial diamond growth by chemical vapor deposition
(1996)
To address the relative lack of understanding concerning growth mechanisms for diamond chemical vapor deposition (CVD), this work explores kinetics of diamond epitaxy--growth on single-crystal substrates--and morphology ...
An efficient method for analyzing the optimal modes of vibration for polyatomic molecules
(1994)
A quantitative analysis of the vibrational spectra of polyatomic molecules in the high energy regime requires a determination of the proper modes that optimally describe the vibrational motions of the nuclei at these ...
