ABSOLUTE PHOTODISSOCIATION QUANTUM YIELDS FOR THE NO3 FREE RADICAL

ABSOLUTE PHOTODISSOCIATION QUANTUM YIELDS FOR THE NO3 FREE RADICAL

Date: January 1, 1980
Creator: Magnotta, Frank & Johnston, Harold S.
Description: The nitrate free radical was photolyzed by a pulsed tunable dye laser between 470 and 685 nm, at 296 K, and in the presence of 10 torr N{sub 2}. The two product channels, NO + O{sub 2} and NO{sub 2} + O, were measured by resonance fluorescence of NO or of O. Absolute calibration of the method was achieved by in situ ultraviolet photolysis of NO{sub 2}, which yields both NO and O. With these data on photochemical yields, the photolysis coefficients for the two product channels at the surface of the earth with an overhead sun over wavelengths 470-700 nm are calculated to be j{sub 1}(NO + O{sub 2}) = 0.022 {+-} 0.007 s{sup -1} and j{sub 2}(NO{sub 2} + O) = 0.18 {+-} 0.06 s{sup -1}.

THE APPLICATION OF HIGH RESOLUTION ELECTRON ENERGY LOSS SPECTROSCOPY TO THE CHARACTERIZATION OF ADSORBED MOLECULES ON RHODIUM SINGLE CRYSTAL SURFACES

THE APPLICATION OF HIGH RESOLUTION ELECTRON ENERGY LOSS SPECTROSCOPY TO THE CHARACTERIZATION OF ADSORBED MOLECULES ON RHODIUM SINGLE CRYSTAL SURFACES

Date: January 1, 1980
Creator: Dubois, L.H. & Somorjai, G.A.
Description: The scattering of low energy electrons by metal surfaces has been studied for many years now. The electron's ease of generation and detection and high surface sensitivity (low penetration depth) make it an ideal probe for surface scientists. The impinging electron can interact with the surface in basically two ways: it can either elastically reflect (or diffract) from the surface without losing energy or lose a portion of it's incident energy and inelastically scatter. In this paper we will be concerned with only one of many possible inelastic scattering processes: the loss of the electron's energy to the vibrational modes of atoms and molecules chemisorbed on the surface. This technique is known as high resolution electron energy loss spectroscopy (or ELS, EELS, HRELS, HREELS, etc.).

CLASSICAL MODEL FOR LASER-INDUCED NON-ADIABATIC COLLISION PROCESSES

CLASSICAL MODEL FOR LASER-INDUCED NON-ADIABATIC COLLISION PROCESSES

Date: January 1, 1980
Creator: Orel, Ann E. & Miller, William H.
Description: By synthesizing earlier work of Orel and Miller and of Meyer, McCurdy, and Miller, a model for describing laser-induced electronically non-adiabatic collision processes is constructed which treats all degrees of freedom -- heavy particle (i.e,, translation, rotation, and vibration), electronic, and photon by classical mechanics. This then makes it relatively easy to carry out calculations to simulate such processes within a dynatnically consistent framework. Application is made to the test case H + LiF {yields} Li + HF reaction considered by Light and Altenberger-Siczek. The most interesting feature revealed by these classical calculations is maxima in the reaction probability as a function of initial translational energy at energies below the laser-free threshold. It is seen that this structure can be understood as a Franck-Condon-like effect.

Conceptual Design of Electrical Balance of Plant for Advanced Battery Energy Storage Facility. Annual Report March 1979

Conceptual Design of Electrical Balance of Plant for Advanced Battery Energy Storage Facility. Annual Report March 1979

Date: January 1980
Creator: King, Joseph M.; Vivirito, Joseph R. & Kornbrust, Frederick J.
Description: Large-scale efforts are in progress to develop advanced batteries for utility energy storage systems. Realization of the full benefits available from those systems requires development, not only of the batteries themselves, but also the ac/dc power converter, the bulk power interconnecting equipment, and the peripheral electric balance of plant equipment that integrate the battery/converter into a properly controlled and protected energy system. This study addresses these overall system aspects; although tailored to a 20-MW, 100-MWh lithium/sulfide battery system, the technology and concepts are applicable to any battery energy storage system.

Corrosion Behavior of Several Metals in Ethylene Glycol-Base Heat-Transfer Fluids under Conditions Encountered in Solar Energy Systems

Corrosion Behavior of Several Metals in Ethylene Glycol-Base Heat-Transfer Fluids under Conditions Encountered in Solar Energy Systems

Date: January 1980
Creator: Zeman, G. J.
Description: The corrosion behavior of aluminum, copper, and iron in inhibited ethylene glycol-ASTM corrosive water solutions was evaluated in a laboratory loop under isothermal and heat-flux conditions for 1000 h at temperatures between 378 and 413 degrees K, in static autoclave tests at 450 degrees K for 500 h, and by potentiodynamic polarization measurements at temperatures between 298 and 348 degrees K. The effect of time, temperature, and ethylene glycol concentration of the heat-transfer fluid on the extent of inhibitor depletion was determined from analyses of the reserve alkalinity, pH, and inhibitor content of the solutions. The performance of an electrochemical sensor as a monitor of fluid quality was also evaluated. A heat flux of 0.4 to 1.0 kW/m sq. did not have a significant effect on the corrosion behavior of the various materials at temperatures between 378 and 413 degrees K. The corrosion rates of aluminum, copper, and iron in the 50 volume percent inhibited ethylene glycol-corrosive water solution decreased as a function of time during the 1000-h test. At 413 degrees K, the corrosion rate of copper was considerably higher than that of iron or aluminum at low flow velocity. Significant degradation of the fluid quality, as indicated by ...

Development of Nondestructive Evaluation Techniques for High-Temperature Ceramic Heat Exchanger Components : Third Annual Report, October 1979-September 1980

Date: 1980
Creator: Kupperman, D. S.; Yuhas, D.; Sciammarella, Cesar A.; Caines, M. J. & Winiecki, A.
Description: The goals of the present program are not only to develop hardware and procedures for efficiently inspecting ceramic heat-exchanger components in conventional ways, but also to develop advanced NDE techniques that will allow effective failure prediction. The main objectives in FY 1980 have been to (a) develop a computer-interfaced ultrasonic bore-side probe for pre-service and in-service inspection, (b) develop and assess techniques for inspection of SiC tubing by acoustic microscopy, and (c) carry out preliminary tests to compare ultrasonic, holographic, and infrared techniques with more conventional dye-penetrant and radiographic methods for inspection of butt joints in ceramic tubes. Circumferential notches, 125 microns deep x 250 microns long, on the inner and outer surfaces of sintered and siliconized SiC tubes were successfully detected with an ultrasonic bore-side probe. The acoustic microscope was modified to handle 30- as well as 100-MHz sound waves, since the lower-frequency waves give better penetration of Sic tube walls. The modification decreased the acoustic noise. The ability to detect a notch only 250 x 125 x 75 microns in size was demonstrated. Efforts to examine a butt joint with dye-penetrant, radiographic, ultrasonic, and holographic-interferometry techniques revealed that while holography seemed to identify more clearly the presence of ...

ELECTRON BEAM SENSITIVITY AND STRUCTURE OF THE GLASSY PHASE OF CERAMICS

ELECTRON BEAM SENSITIVITY AND STRUCTURE OF THE GLASSY PHASE OF CERAMICS

Date: January 1, 1980
Creator: Laval, J.Y. & Westmacott, K.H.
Description: The electron beam sensitivity of glassy ceramics was reviewed. It was shown that the glassy phase resulting from the segregation of additives such as CaO or MgO at the grain boundaries was highly sensitive to the electron beam. We have reported elsewhere that the electron damage kinetics corresponds to an ionization process (Laval, Westmacott, 1979). This ionization process was discussed in terms of chemical bondings and ionic states, and by referring to the soda-glass structure. From these considerations new insights into the structure of the glassy phase were obtained. From the nature of the ionization effects it is possible to postulate which ion will lead to the damage and therefore to know the structure and the composition of the glassy phase on a nanometric scale. Thus the electron beam sensitivity of glassy ceramic enables a very thin intergranular glassy phase to be characterized and is of great value in determining the structure of the grain boundaries and of metal-oxide or glass-ceramic interfaces.

ENERGY CONSERVATION AND ENERGY DECENTRALIZATION: ISSUES AND PROSPECTS

ENERGY CONSERVATION AND ENERGY DECENTRALIZATION: ISSUES AND PROSPECTS

Date: January 1, 1980
Creator: Levine, Mark D. & Craig, Paul P.
Description: We have presented views of the seemingly paradoxical nature and irrationality of the energy system and the decisions that determine its evolution. An economic approach to energy decisions, while widely espoused and generally believed to be the underpinning of our system. appears not to be functioning in very important areas. The result is enormous waste of economic and intangible resources to produce energy that could be effectively replaced by energy conservation at low costs. This inefficiency in the economic system is, in our judgment. far greater than is recognized either by the public or by 'experts.' It has led to an over-investment in centralized energy systems and has discouraged the use of decentralized systems that could contribute significantly in the near term to a lessening of our energy problems. There are some signs that the situation is changing. albeit rather slowly. High prices and the widespread recognition of the seriousness of our energy problems have contributed to an increasing involvement of individuals in energy decisions profoundly affecting their future. To achieve an evolution of the energy system in which decentralized technologies (and, in the near term, particularly technologies that improve the efficiency of energy use) play an important role, the ...

EVOLUTION OF PROJECTILE DOUBLE K VACANCY FRACTIONS WITH TARGET THICKNESS IN ION-ATOM COLLISIONS

EVOLUTION OF PROJECTILE DOUBLE K VACANCY FRACTIONS WITH TARGET THICKNESS IN ION-ATOM COLLISIONS

Date: January 1, 1980
Creator: Tanis, J.A.; Shafroth, S.M.; Willis, J.E. & Mowat, J.R.
Description: The dependence of projectile double K-vacancy (hypersatellite) x-ray yields on target thickness for ions moving in thin solid targets is examined. For 2.3 MeV/amu Cl ions incident on C foils, the double-to-single K vacancy x-ray yield increases by a factor of 3.5 over the range of thicknesses investigated, reaching values as high as 30%. A quantitative explanation of the observed results is obtained using the three-component model of Gardner et al.
