Structural Formation Studies of UV-Catalyzed Gels and Aerogels by Light Scattering

Description: The skeletal structure of aerogel is determined before, during, and after the gel is formed. Supercritical drying of aerogel largely preserves the pore structure that is determined near the time of gelation. To better understand these gel formation mechanisms we carried out measurements of the time evolution of light scattering in a series of gels prepared without conventional acid or base catalysis. Instead, ultraviolet light was used to catalyze the formation of silica gels made from the hydr… more

Solar power towers

Description: The high desert near Barstow, California, has witnessed the development of this country`s first two solar power towers. Solar One operated successfully from 1982 to 1988 and proved that power towers work efficiently to produce utility-scale power from sunlight. Solar Two was connected to the utility grid in 1996 and is operating today. Like its predecessor, Solar Two is rated at 10 megawatts. An upgrade of the Solar One plant, Solar Two demonstrates how solar energy can be stored in the form of… more

Solar buildings. Overview: The Solar Buildings Program

Description: Buildings account for more than one third of the energy used in the United States each year, consuming vast amounts of electricity, natural gas, and fuel oil. Given this level of consumption, the buildings sector is rife with opportunity for alternative energy technologies. The US Department of Energy`s Solar Buildings Program was established to take advantage of this opportunity. The Solar Buildings Program is engaged in research, development, and deployment on solar thermal technologies, whic… more

Solar dish/engine systems

Description: Solar dish/engine systems convert the energy from the sun into electricity at a very high efficiency. Using a mirror array formed into the shape of a dish, the solar dish focuses the sun`s rays onto a receiver. The receiver transmits the energy to an engine that generates electric power. Because of the high concentration ratios achievable with parabolic dishes and the small size of the receiver, solar dishes are efficient at collecting solar energy at very high temperatures. Tests of prototype … more

Solar Two

Description: Solar Two is a concentrating solar power plant that can supply electric power on demand to the local utility, Southern California Edison Company. It can do so because it operates not only during sunny parts of the day, but it can store enough thermal energy from the sun to operate during cloudy periods and after dark, for up to three hours, at its rated output of 10 megawatts (MW). For the first time ever, a utility scale solar power plant can supply electricity when the utility needs it most, … more

M Theory on AdSp x 511-p and superconformal field theories

Description: We study the large N limit of the interacting superconformal field theories associated with N M5 branes or M2 branes using the recently proposed relation between these theories and M theory on AdS spaces. We first analyze the spectrum of chiral operators of the 6d (0, 2) theory associated with M5 branes in flat space, and find full agreement with earlier results obtained using its DLCQ description as quantum mechanics on a moduli space of instantons. We then perform a similar analysis for the D… more

MAINTENANCE OF THE COAL SAMPLE BANK AND DATABASE

Description: This project provides coal samples and accompanying analytical data for research by DOE contractors and others. All 56 samples have been purged with argon before storage, and the 33 samples in the DECS series are heat-sealed in foil laminate bags and stored under refrigeration. Eleven DECS samples have been collected under the current contract. Basic characterization, standardized liquefaction analyses and organic geochemical analyses have been completed. Distribution of samples and data is con… more

Nondestructive evaluation and characterization of damage and repair to continuous-fiber ceramic composite panels.

Description: Continuous fiber ceramic matrix composites are currently being developed for a variety of high-temperature applications. Because of the high costs of making these components, minor damage incurred during manufacturing or operation must be rewired in order to extend the life of the components. In this study, five ceramic-grade Nicalon{trademark} fiber/SiNC-matrix composite panels were intentionally damaged with a pendulum-type impactor during an impact test. The damaged panels were then repaired… more

Thermal imaging and air-coupled ultrasound characterization of a continuous-fiber ceramic composite panels.

Description: SYLRAMIC{trademark} continuous fiber ceramic-matrix composites (Nicalon{trademark} fiber/SiNC matrix) were fabricated by Dow Corning Corporation with the polymer-impregnation and pyrolysis (PIP) process. The composite microstructure and its uniformity, and the completeness of infiltration during processing were studied as a function of number of PIP cycles. Two nondestructive evaluation (NDE) methods, i.e., infrared thermal imaging and air-coupled ultrasound (UT), were used to investigate flat … more

Measurements of the Argonne Wakefield Accelerator's low charge, 4 MeV RF photocathode witness beam.

Description: The Argonne Wakefield Accelerator's (AWA) witness RF photocathode gun produced its first electron beam in April of 1996. We have characterized the charge, energy, emittance and bunch length of the witness beam over the last several months. The emittance Was measured by both a quad scan that fitted for space charge using an in house developed Mathematica routine and a pepper pot technique. The bunch length was measured by imaging Cherenkov light from a quartz plate to a Hamamatsu streak camera w… more

Using the Malcolm Baldridge criteria: a viable tool for assessing organizational change

Description: How does understanding and using the Malcolm Baldrige criteria impact library organizational change? In September 1997, the Los Alarnos National Laboratory Research Library used the criteria to apply for a Quality New Mexico Award (QNMA). This paper will provide a fimdamental background on the Malcolm Baldrige criteria and outline the Library project to apply for the award. The Research Library learned from the project and feedback and has started implementing steps to increase its effectivenes… more
