Novel Scanning Lens Instrument for Evaluating Fresnel Lens Performance: Equipment Development and Initial Results

Description: A system dedicated to the optical transmittance characterization of Fresnel lenses has been developed at NREL, in collaboration with the UPM. The system quantifies the optical efficiency of the lens by generating a performance map. The shape of the focused spot may also be analyzed to understand change in the lens performance. The primary instrument components (lasers and CCD detector) have been characterized to confirm their capability for performing optical transmittance measurements. Measure… more

Letter Report for Characterization of Biochar

Description: On 27 November 2012, a bulk biochar sample was received for characterization of selected physical and chemical properties. The main purpose of the characterization was to help determine the degree to which biochar would be suitable as a soil amendment to aid in growth of plants. Towards this end, analyses to determine specific surface, pH, cation-exchange capacity, water retention, and wettability (i.e. surface tension) were conducted. A second objective was to determine how uniform these prope… more

Characteristics of KE Basin Sludge Samples Archived in the RPL - 2007

Description: Samples of sludge were collected from the K East fuel storage basin (KE Basin) floor, contiguous pits (Weasel Pit, North Load Out Pit, Dummy Elevator Pit, and Tech View Pit), and fuel storage canisters between 1995 and 2003 for chemical and radionuclide concentration analysis, physical property determination, and chemical process testing work. Because of the value of the sludge in this testing and because of the cost of obtaining additional fresh samples, an ongoing program of sludge preservati… more

Rh-Based Mixed Alcohol Synthesis Catalysts: Characterization and Computational Report

Description: The U.S. Department of Energy is conducting a program focused on developing a process for the conversion of biomass to bio-based fuels and co-products. Biomass-derived syngas is converted thermochemically within a temperature range of 240 to 330°C and at elevated pressure (e.g., 1200 psig) over a catalyst. Ethanol is the desired reaction product, although other side compounds are produced, including C3 to C5 alcohols; higher (i.e., greater than C1) oxygenates such as methyl acetate, ethyl aceta… more

Characterization of Material from Wells 299-W10-35 (C7573) and 299-W14-74 (C7024)

Description: The objective of this work was to characterize material accumulating on wells 299-W10-35 (C7573) and 299-W14-74 (C7024) to determine the type of material (i.e., chemical or biological) and, if the material is biological, to identify the microorganisms present.

Beam Characterization at the Neutron Radiography Facility

Description: The quality of a neutron imaging beam directly impacts the quality of radiographic images produced using that beam. Fully characterizing a neutron beam, including determination of the beam’s effective length-to-diameter ratio, neutron flux profile, energy spectrum, image quality, and beam divergence, is vital for producing quality radiographic images. This project characterized the east neutron imaging beamline at the Idaho National Laboratory Neutron Radiography Reactor (NRAD). The experiments… more

Evaluation of Northern Illinois Residential Retrofit Delivery Practices

Description: Using a detailed BEopt analysis, PARR has developed packages of measures following a 'loading order' appropriate for cold climates at increasing levels of savings. Packages of measures to provide 'good, better, best' energy savings were determined based on predicted source energy savings, safety issues, program costs and simple payback for customers.

Measurement and Modeling of Solar and PV Output Variability: Preprint

Description: This paper seeks to understand what temporal and spatial scales of variability in global horizontal radiation are important to a PV plants and what measurements are needed to be able to characterize them. As solar radiation measuring instruments are point receivers it is important to understand how those measurements translate to energy received over a larger spatial extent. Also of importance is the temporal natural of variability over large spatial areas. In this research we use high temporal… more

Isolation and Characterization of Phages Infecting Streptomyces azureus

Description: Isolating novel phages using Streptomyces azureus, which produces antibiotic thiostrepton, as a host, and characterizing the genomes may help us to find new tools that could be used to develop antibiotics in addition to contribute to the databases of phages and specifically, Streptomyces phages. Streptomyces phages Alsaber, Omar, Attoomi, Rowa, and ZamZam were isolated using during this study. They were isolated from enriched soil and sequenced by Illumina sequencing method.
