Verkhoturov, S. V.; Schweikert, E. A.; Chechik, Victor; Sabapathy, Rajaram C.; Crooks, Richard M.; Parilis, E. S. (Physical Review Letters, 2001)
-
Hill, John Chester (Texas A&M University. Libraries, 1987)A new Cf-252 plasma desorption mass spectrometer has been built specifically for the analysis of large biomolecules. This mass spectrometer was used to investigate the interactions between proteins adsorbed onto polymer ...
-
Magnussen, Nancy Denise (Texas A&M University. Libraries, 1994)Anodic oxide films are used extensively in a variety of applications. This study focuses on characterization of anodic oxide films grown on valve-type metals (Ti, Zr, Nb and Hf) under a variety of experimental conditions. ...
-
Blain, Matthew Glenn (Texas A&M University. Libraries, 1990)A new experimental method has been developed for studying negative secondary ion (SI) emission from solid surfaces bombarded by polyatomic primary ions of 5 to 30 keV. The method is based on the time-of-flight (TOF) analysis ...
-
Park, Melvin Andrew (Texas A&M University. Libraries, 1991)Coincidence counting has been combined with time-of-flight mass spectrometry (TOF-MS) in a study of the relationships of secondary ions desorbed by keV and MeV energy primary ions. Secondary ions are in coincidence with ...
-
Demarest, John Allen (Texas A&M University. Libraries, 1986)A study of the extreme ultaviolet radiation emitted by ion beams of highly ionized neon and argon after passage through thin foils was conducted at the variable energy cyclotron at Texas A&M University. A grazing incidence ...
-
Harrison, Gabrielle Vuon (Texas A&M University. Libraries, 1982)Direct analysis of organotin compounds by graphite furnace atomic absorption (GFAA) spectrometry is complicated by the presence of chemical interferences that cause a species-dependent sensitivity. To reduce these interferences ...
-
Hiller, John Michael (Texas A&M University. Libraries, 1980)The variations in the potentials of the sodium-selective glass-membrane and potassium-selective valinomycin-based electrodes in various concentrations of albumin were investigated. These protein solutions serve as a simple ...
-
Taylor, Robert Joseph (Texas A&M University. Libraries, 1987)The sediment geochemistry of Mn at a site in Galveston Bay, Texas, was investigated through a three-fold approach. A field study demonstrated that despite the coarse, quartz-rich nature of the bottom sediments, Mn was ...
-
Roederer, Joy Elain (Texas A&M University. Libraries, 1984)A new immunoassay technique has been developed using piezoelectric quartz plates, which undergo physical deformation in response to electrical charge. An oscillating electrical circuit causes the crystal to alternately ...
-
Aylmer, David Matthe (Texas A&M University. Libraries, 1983)Coal Analysis is ordinarily divided into three parts: (1) Proximate analysis, determination of moisture, volatile matter, fixed carbon and ash contents; (2) Ultimate analysis, determination of carbon, hydrogen, sulfur, ...
-
Hyman, Marian (Texas A&M University. Libraries, 1982)The content and distribution of magnetite in carbonaceous chondrites is of particular interest since it is a substantial component in these, the most primitive materials surviving from solar system formation. Previous ...
-
Beug, Maria Ursula Dorothea (Texas A&M University. Libraries, 1987)The goal of this study has been to expand the analytical scope of ²⁵²Cf particle desorption mass spectrometry (PDMS). The technique has a unique set of features: simple spectra, usually with a predominant parent ion peak ...
-
Yoon, Cheonho (Texas A&M University. Libraries, 1986)The oxidation behavior of an alloy system with unique electronic properties and the challenge to prepare a planar model for the very active oxidation catalyst, Hopcalite, were attacked. Surface segregation phenomena of ...
-
Zikovsky, Lubomir (Texas A&M University. Libraries, 1977)The capabilities of 12 MeV proton activation were compared with those of reactor neutron and 35 MeV photon activation. A series of biological specimens (plant and animal tissues) were chosen for this study limited to ...
