New Design Methods And Algorithms For High Energy-Efficient And Low-cost Distillation Processes

Description: This project sought and successfully answered two big challenges facing the creation of low-energy, cost-effective, zeotropic multi-component distillation processes: first, identification of an efficient search space that includes all the useful distillation configurations and no undesired configurations; second, development of an algorithm to search the space efficiently and generate an array of low-energy options for industrial multi-component mixtures. Such mixtures are found in large-scale … more

The Lord's Resistance Army: The U.S. Response

Description: This report discusses the Lord's Resistance Army (LRA) and United States policy, strategic and humanitarian response. LRA is an armed group that originated in northern Uganda 24 years ago but has operated since 2006 in the remote border areas between the Central African Republic (CAR), Democratic Republic of Congo (DRC), and South Sudan. Led by Joseph Kony, its numbers are tiny, but its actions, which include massacres, mass abductions, sexual assault, and looting, have caused significant human… more

Development of Electrochemical Photovoltaic Cells. Second Technical Progress Report, August 1, 1979-October 31, 1979

Description: The development of stable, efficient, photoelectrochemical cells based on silicon and gallium arsenide in non-aqueous electrolyte systems is being investigated. Redox reactions of ferrocene, anthracene and anthraquinone have been studied on platinum and n-silicon electrodes. The latter have been further characterized by differential capacitance measurements. Cells and equipment have been designed and set up for long-term stability studies.

Spinning characteristics of wings 1: rectangular Clark Y monoplane wing

Description: "A series of wind tunnel tests of a rectangular Clark Y wing was made with the NACA spinning balance as part of a general program of research on airplane spinning. All six components of the aerodynamic force and moment were measured throughout the range of angles of attack, angles of sideslip, and values omega b/2v likely to be attained by a spinning airplane; the results were reduced to coefficient form. It is concluded that a conventional monoplane with a rectangular Clark y wing can be made … more

Thermal performance of steel-framed walls. Final report

Description: In wall construction, highly conductive members spaced along the wall, which allow higher heat transfer than that through less conductive areas, are referred to as thermal bridges. Thermal bridges in walls tend to increase heat loss and, under certain adverse conditions, can cause dust streaking (``ghosting``) on interior walls over studs due to temperature differentials, as well as condensation in and on walls. Although such adverse conditions can be easily avoided by proper thermal design of … more

Scientists use GEANIE to Study Isotopes of Iridium and Europium to Improve Radiochemical Diagnostics in Nuclear Devices

Description: Radiochemical diagnostics play an important role in helping scientists understand the detonation of a nuclear device. Sometimes some elements or isotopes are inserted as radiochemical detectors at various locations in the nuclear device. During the detonation of the device, these detectors are subjected for a short time to the intense flux of neutrons emitted through fission and possibly through fusion of light elements (usually deuterium and tritium). After the detonation, the radiochemical de… more

Scientific/Technical Report

Description: This symposium aimed to bring together researchers working on quantifying nanoscale carrier transport processes in excitonic solar cells. Excitonic solar cells, including all-organic, hybrid organic-inorganic and dye-sensitized solar cells (DSSCs), offer strong potential for inexpensive and large-area solar energy conversion. Unlike traditional inorganic semiconductor solar cells, where all the charge generation and collection processes are well understood, these excitonic solar cells contain e… more

Argonne National Laboratory Biology Division Quarterly Report: August to October, 1946

Description: From introductory paragraph: "This is the first quarterly report of the Biology Division of the Argonne National Laboratory. During the three-month period covered by this report, a large share of the time of many investigators has been spent in collating work done under the Biology Section of the Metallurgical laboratory for publication in the Plutonium Project Record. The large amount of work done under wartime pressure has made this, as in other divisions and projects, an important part of th… more

Evaluation of BeO ceramic disks for thermally stimulated exoelectron dosimetry

Description: BeO ceramic disks were evaluated for application as dosimeters for both penetrating and non-penetrating radiation. Response to penetrating radiation was measured as thermoluminescence (TL) and to non-penetrating radiation as thermally stimulated exoelectron emission (TSEE). Field experiments demonstrated that both TSEE and TL responses from BeO can monitor diverse radiation fields. BeO disks in a passive dosimeter were found to be sensitive to a lower exposure level of 100 pCi-day/liter of rado… more

Energy Saving Melting and Revert Reduction Technology (E0SMARRT): Predicting Pattern Tooling and Casting Dimension for Investment Casting

Description: The investment casting process is an expendable mold process where wax patterns of the part and rigging are molded, assembled, shelled and melted to produce a ceramic mold matching the shape of the component to be cast. Investment casting is an important manufacturing method for critical parts because of the ability to maintain dimensional shape and tolerances. However, these tolerances can be easily exceeded if the molding components do not maintain their individual shapes well. In the investm… more

Analysis of E-N target conversion data

Description: Production efficiency studies of the E-N loading require that conversion ratio values for both plutonium and tritium be defined. Changing of the core-loading charge makeup with each core load to obtain a more efficient loading has theoretically resulted in increasing the tritium conversion ratio. Tritium recovery data from the third H Reactor E-N loading has recently become available for analysis. The buildup of product is much slower in fringe blanket material then in core target pieces. The s… more
