Rapid assessment of soil and groundwater tritium by vegetation sampling

Rapid assessment of soil and groundwater tritium by vegetation sampling

Date: September 1995
Creator: Murphy, C. E., Jr.
Description: A rapid and relatively inexpensive technique for defining the extent of groundwater contamination by tritium has been investigated. The technique uses existing vegetation to sample the groundwater. Water taken up by deep rooted trees is collected by enclosing tree branches in clear plastic bags. Water evaporated from the leaves condenses on the inner surface of the bag. The water is removed from the bag with a syringe. The bags can be sampled many times. Tritium in the water is detected by liquid scintillation counting. The water collected in the bags has no color and counts as well as distilled water reference samples. The technique was used in an area of known tritium contamination and proved to be useful in defining the extent of tritium contamination.

Tritium Deposition in Pine Trees and Soil from Atmospheric Releases of Molecular Tritium

Tritium Deposition in Pine Trees and Soil from Atmospheric Releases of Molecular Tritium

Date: February 16, 1982
Creator: Murphy, C.E. Jr.
Description: Much of the tritium found in soil and leaf litter near a chemical separations facility is incorporated into soil organic matter in a stable non-exchangeable form. Formation of this ''bound'' tritium seems to result from the uptake of molecular tritium (HT) by living pine needles. Soil and litter microbes convert HT to HTO more rapidly, but no measurable organic tritium is formed. This report discusses this study.

The Uptake of Hydrogen Fluoride by a Forest

The Uptake of Hydrogen Fluoride by a Forest

Date: December 18, 1980
Creator: Murphy, C.E. Jr.
Description: A mathematical model of hydrogen fluoride (HF) deposition and accumulation of fluoride in a Eucalyptus rostrata forest has been developed. The model is based on tree physiology and meteorological principles. The data base for the model was derived from a literature survey of the physiological characteristics of E. rostrata and similar eucalyptus species and from current knowledge of meteorological processes in plant canopies.

The brass plug monument system for Doubler alignment

The brass plug monument system for Doubler alignment

Date: September 4, 1981
Creator: Murphy, C. T.
Description: The system of brass plugs set in the Main Ring tunnel floor for use in radial alignment of Doubler elements is described. Considerations leading to the choice of plug positions and properties are discussed. The quantitative relationship between the plugs and the Doubler orbit is presented in sufficient detail so that they can be used by anybody to align Doubler elements both radially and along the beam. Neither the origin or the accuracy of the system is discussed in detail.

PATCHY SILICA-COATED SILVER NANOWIRES AS SERS SUBSTRATES

PATCHY SILICA-COATED SILVER NANOWIRES AS SERS SUBSTRATES

Date: March 29, 2013
Creator: Murph, S. & Murphy, C.
Description: We report a class of core-shell nanomaterials that can be used as efficient surface-enhancement Raman scattering (SERS) substrates. The core consists of silver nanowires, prepared through a chemical reduction process, that are used to capture 4- mercaptobenzoic acid (4-MBA), a model analyte. The shell was prepared through a modified Stöber method and consists of patchy or full silica coats. The formation of silica coats was monitored via transmission electron microscopy, UV-visible spectroscopy and phase-analysis light scattering for measuring effective surface charge. Surprisingly, the patchy silica coated silver nanowires are better SERS substrate than silver nanowires; nanomolar concentration of 4-MBA can be detected. In addition, “nano-matryoshka” configurations were used to quantitate/explore the effect of the electromagnetic field at the tips of the nanowire (“hot spots”) in the Raman scattering experiment.

Analytical theory of multipass crystal extraction

Analytical theory of multipass crystal extraction

Date: October 1, 1997
Creator: Biryukov, V. & Murphy, C.T.
Description: An analytical theory for the efficiency of particle extraction from an accelerator by means of a bent crystal is proposed. The theory agrees with all the measurements performed in the broad energy range of 14 to 900 GeV, where the efficiency range also spans over two decades, from {approximately}0.3% to {approximately}30%.
