Developing a targeting system for bacterial membranes: measuring receptor-phosphatidylglycerol interactions with H-1 NMR, ITC and fluorescence correlation spectroscopy
(Royal Society of Chemistry, 2015)An ammonium picket porphyrin that targets bacterial membranes has been prepared and shown to bind to phosphatidylglycerol (PG), a bacterial lipid, when the lipid was in solution, contained within synthetic membrane vesicles, ... -
Development of a method to investigate intra-molecular proton migration during collision induced dissociation of gas-phase peptides
(2005-12)Use of a combination of hydrogen/deuterium (H/D) exchange, mass spectrometry (MS) and/or CID is a rapidly evolving approach to the investigation of protein structure and conformation and the dynamics of conformational ... -
DFT models of molecular species in carbonate molten salts
(American Chemical Association, 2012-05-10)Raman spectra of high temperature carbonate melts are correlated with carbonate species modeled at 923 K using B3LYP/(6-311+G(2d,p)) density functional calculations. Species that are theoretically stable at 923 K include ... -
Dicyano and pyridine derivatives of retinal: synthesis and vibronic, electronic, and photophysical properties
(American Chemical Society, 2010-07-01)Two new derivatives of all-trans retinal, one containing a pyridine and a cyanide substituent, all-trans-15-cyano-15'-pyridylretinal (2), and the other containing two cyanide substituents, all-trans-15,15'-dicyanoretinal ... -
Dicyano and pyridine derivatives of ß-carotene: synthesis and vibronic, electronic, and photophysical properties
(American Chemical Society, 2011-02-17)Density functional theory and time-dependent density functional theory calculations provide pictures of the molecular orbitals involved in the ground and excited states of two cyano derivatives of 8′-apo-β-caroten-8′-al ... -
Differential ion mobility separations in the low-pressure regime
(American Chemical Society, 2018-01-02)Ion mobility spectrometry (IMS) in conjunction with mass spectrometry (MS) has emerged as a powerful platform for biological and environmental analyses. An inherent advantage of differential or field asymmetric waveform ... -
Differential ion mobility separations/mass spectrometry with high resolution in both dimensions
(American Chemical Society, 2019-01-15)Strong orthogonality to mass spectrometry makes differential ion mobility spectrometry (FAIMS) a powerful tool for isomer separations. However, high FAIMS resolution has been achieved overall only with buffers rich in He ... -
Digital data usage in the chemistry classroom and laboratory
(American Chemical Society, 2014-08-10)It is important for science students to understand the basic concepts of statistical analysis and both linear regression and non-linear regression analysis of digital experimental data. Excel spreadsheets are often used ... -
