(2009-05-15)Uronate isomerase catalyzes the isomerization of D-glucuronate and Dfructuronate. This enzyme has been classified as a member of the amidohydrolase superfamily. The reaction catalyzed by uronate isomerase is analogous to ...
-
(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 ...
-
(2016-08-05)Ligand design has been an often pursued strategy to advance the development of transition metal complexes for catalysis and activation of small molecules. In the past decade, polydentate Z-type ligands have been recognized ...
-
Application of Advanced Laser and Optical Diagnostics Towards Non-Thermochemical Equilibrium Systems (2010-07-14)The Multidisciplinary University Research Initiative (MURI) research at Texas A and M University is concerned with the experimental characterization of non-thermal and non-chemical equilibrium systems in hypersonic (Mach ...
-
(Texas A&M University, 2005-11-01)Surfaces can be probed with a variant of secondary ion mass spectrometry (SIMS) where the bombardment is with a sequence of single keV projectiles, each resolved in time and space, coupled with the separate record of the ...
-
(2013-03-13)Nuclear magnetic resonance (NMR) spectroscopy is one of the most important analytical tools for organic and biological chemistry. It provides not only detailed information on the structure of small molecules and macromolecules, ...
-
(2012-02-14)Nuclear magnetic resonance (NMR) yields remarkably detailed structural information about virtually any molecule. However, its application to non-equilibrium systems is hampered by a lack of sensitivity. To increase the ...
-
(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 ...
-
(2009-05-15)A variety of biological and organic reaction mechanisms are studied using powerful tools from experimental and theoretical chemistry. These tools include the precise measurement of kinetic isotope effects (KIEs) and the ...
-
(2014-12-10)Eukaryotic cells contain low-molecular-mass metal complexes (LMMMCs), defined as having masses between 200 – 10,000 Da, but these so-called labile or chelatable metal pools are poorly defined in terms of structures and ...
-
(2021-08-18)Native mass spectrometry (nMS) is an expanding technique whereby ions with low internal energies are ionized and non-covalent structural elements remain intact following desolvation from solution-phase molecules to ...
-
(2011-10-21)Natural products continue to inspire synthetic chemists to develop novel methodologies to provide efficient and expedient syntheses of the target molecules. Haterumalide NA aroused our interest and prompted development of ...
-
(2020-04-14)The proposed mechanism of fibril formation of transthyretin (TTR) involves self-assembly of partially unfolded monomers. However, the mechanism(s) of disassembly to monomer and potential intermediates involved in this ...
-
(2023-01-05)Nuclear magnetic resonance (NMR) spectroscopy is a popular analytic technique in chemistry despite its intrinsic, low sensitivity. Nuclear spin hyperpolarization methods can improve NMR signals by several orders of magnitude ...
-
(2011-08-08)This dissertation focused on the applications of self-assembled monolayers (SAMs) technique for the investigation of molecule based electronics, plasmon coupling between CdSe quantum dots and metal nanoparticles (MNPs), ...
-
(2009-05-15)Triazine chemistry has many applications from industrial usage, such as melamine resins, to academic interests in dendritic structures which may one day come to fruition as pharmaceutically applicable molecules. Organic ...
-
(2020-07-16)When NMR spectra of chiral racemic organic molecules containing a Lewis basic functional group are recorded in the presence of air and water stable salts of the cobalt(III) trication [Co((S,S)-NH2CHArCHArNH2)3]3+ ((S,S)-23+ ...
-
(2020-09-09)Several forensic analyses have been performed on irradiated UO2 and weapons usable Pu to discriminate their origin and history. The discrimination techniques applied here may be used to aid intelligence officials in the ...
-
(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. ...
-
(2020-10-13)Ladder-type conjugated molecules and macromolecules are attractive organic materials with optical and electronic properties suitable for various applications, as a result of their extended π-delocalization and strong ...
