Sawyer, Holly Ann (Texas A&M University, 2006-04-12)Ion mobility-mass spectrometry (IM-MS), gas-phase hydrogen/deuterium (H/D) exchange ion molecule reactions and molecular modeling provide complimentary information and are used here for the characterization of peptide ion ...
-
Chen, Anqi (2016-08-02)Antimicrobial peptides (AMP) are involved in many biological processes owing to their ability to interact with the cell membranes. The aim of many biophysical methods is to understand the mechanism of AMP function such ...

Castellana, Edward Thomas (2009-05-15)The research presented within this dissertation explores the photocatalytic deposition of metal carried out within sealed microfluidic channels. Micro scale patterning of metals inside sealed microchannels is investigated ...
-
Tao, Lei (2011-08-08)IM-MS is a 2-D technique which provides separations based on ion shape (ion-neutral collision cross-section, Ω) and mass (m/z ratio). Ion structures can be deduced from the measured collision cross-section (Ωmeas) by ...
-
Solouki, Touradj (Texas A&M University. Libraries, 1994)The work presented in this thesis focuses on detection and structural mass spectrometry of large biomolecules by MALDI-FTICR. In Chapter I, overviews of the MALDI technique and advantages of FTICR are given. In Chapter II, ...

Penner, Reginald Mark (Texas A&M University. Libraries, 1987)Fundamental and applied aspects of ion transport in polypyrrole films are investigated. In this context, three objectives have been accomplished: i) Composites of polypyrrole and a porous host membrane have been prepared ...
-
Cologna, Stephanie Marie (2012-02-14)Mass spectrometry (MS) has played a major role in the proteomic analysis of an array of biological samples. Even so, inherent limitations exist such as sample complexity and the dynamic range. In an attempt to overcome ...
-
Tecklenburg, Ronald Edward (Texas A&M University. Libraries, 1988)Ionic cluster fragments of the type M[x](CO)[y]+ are studied by laser-ion beam photodissociation. The systems studied include Mn[x](CO)[y]+ (x =1-2; y=0-10, derived from Mn2(CO)10), Fe[x](CO)[y]+ (x =1-3; y=0-12, derived ...
-
Lewis, Tanya Maranda (Texas A&M University. Libraries, 1994)A unified scheme is developed to demonstrate the necessity of a synergistic approach using several mass spectrometry methods for characterization and identification of water soluble organics in heavy oil retort. Elements ...
-
North, Robert Yates (2011-08-08)Isoelectric trapping (IET) has become an accepted preparative-scale electrophoretic separation technique. However, there are still a number of shortcomings that limit its utility. The performance of the current ...
-
Karlesky, Dori Lynn (Texas A&M University. Libraries, 1985)The first part of this work deals with the development of accurate and reliable procedures for collection and analysis of polynuclear aromatic hydrocarbons (PNAs). The second part shows the application of these procedures ...
-
Chapa, Vanessa Alyss (Texas A&M University, 2007-09-17)The studies presented in this thesis focus on the synthesis of air-stable solid supported lipid bilayers by anhydrobiotic mechanisms. Supported lipid bilayers (SLBs) serve as platforms that mimic cellular membrane surfaces ...
