Russell, David H.; Mclean, John A. (United States. Patent and Trademark Office; Texas A&M University. Libraries, 2007-10-16)The present invention is directed to a novel arrangement of optical devices for the rapid patterning of laser profiles used for desorption and/or ionization sources in analytical mass spectrometry. Specifically, the new ...

Chandra, Richa (2009-06-02)Since cardiovascular disease is one of the leading causes of mortality all over the world, it is becoming increasingly important and relevant to develop new analytical techniques for the analysis of the mechanisms of this ...
-
Zhang, Guannan (2017-10-17)Nuclear magnetic resonance (NMR) spectroscopy is a powerful analytical technique for chemistry and biochemistry. Since an inherent limitation of NMR is a lack of sensitivity, long experimental time with signal averaging ...
-
Mire, Joseph Andrew (2013-07-24)β-lactamase enzymes catalyze the irreversible hydrolysis of the four-membered cyclic amide ring characteristic of β-lactam antibiotics rendering them inactive and useless against pathogenic bacteria. Understanding structure ...
-
Dong, Shiyu (2020-04-20)Metallothioneins (MTs) constitute a family of cysteine-rich proteins that have the ability to bind a wide range of metal ions including Cd^2+, Zn^2+ and Ag^+ . MTs are important in metal homeostasis and detoxification. ...
-
McLean, Janel Renee (2009-05-15)Defining the intrinsic properties of amino acids which dictate the formation of helices, the most common protein secondary structure element, is an essential part of understanding protein folding. Pauling and co-workers ...
-
Schuckman, Amanda Eileen (2012-07-16)Organic molecules such as porphyrins and alkanethiols are currently being investigated for applications such as sensors, light-emitting diodes and single electron transistors. Porphyrins are stable, highly conjugated ...
-
Moore, Robert Bowen (Texas A&M University. Libraries, 1988)High-performance liquid chromatographic procedures were used to study the ion-exchange selectivities of perfluorosulfonate ionomers (PFSI's). HPLC columns were packed with PFSI-coated octadecyl-derivatized silica and were ...
-
Lucas, Jessica Elaine (Texas A&M University, 2004-09-30)Peptide mass fingerprinting (PMF) of protein digests is a widely-accepted method for protein identification in MS-based proteomic studies. Matrix-assisted laser desorption/ionization mass spectrometry (MALDI) is the ...
-
Perez, Gregory Paul (Texas A&M University, 2005-08-29)We have investigated the chemical sensitivity of nanoporous (NP) alumina-coated surface acoustic wave (SAW) devices that have been surface-modified with polymeric mediating films. The research in this dissertation covers the ...
-
Li, Ding (2010-10-12)The chemisorption of aromatic compounds, derivatized with different functional groups, on well-defined Pd(111) surfaces was studied by a combination of Auger electron spectroscopy (AES), low energy electron diffraction ...
-
Lee, Ya-Jung (2012-07-16)Cell-penetrating peptides (CPPs) mediate the delivery of macromolecules across the plasma membrane of live cells. These peptides are therefore important due to the potential of making the delivery of protein probes or ...
-
Pacheco, Jorge Luis (Texas A&M University. Libraries, 1987)The use of laser-excited fluorescence spectroscopy has generated interest as a technique for the measurement of atomic trace concentrations in heterogeneous flame systems. Under saturation of the radiatively excited level ...
-
Marini, Joseph Thomas (Texas A&M University, 2004-09-30)The gas-phase hydrogen/deuterium (H/D) exchange of protonated di- and tripeptides containing a basic amino acid residue has been studied with a Fourier transform ion cyclotron resonance (FT-ICR) mass spectrometer. Bimolecular ...
-
Krailler, Ramona E. (Texas A&M University. Libraries, 1985)Laser induced photodissociation of fast (3-8 keV) ion beams has been developed for use in both a coaxial and perpendicular beam arrangement. The laser-ion beam photodissociation technique has been used as a probe for ...
-
May, Jody C. (2010-10-12)A cryogenic (325-80 K) ion mobility-mass spectrometer was designed and constructed in order to improve the analytical figures-of-merit for the chemical analysis of small mass analytes using ion mobility-mass spectrometry. ...
