(Elsevier, 2018)Fluorine NMR spectroscopy has diverse applications, including characterization of chemical reaction mechanisms, protein structure-function studies, and solid-state NMR characterization of crystalline, amorphous, and soft ... -
Proof of concept for the synthesis of [3.4.3.4] metacyclophane using a porphyrin as a scaffold
(Wichita State University, 2008-05)Several endo- and exo- cyclophanes of various annulus sizes have been synthesized in the past without the benefit of a template and yields were considered moderate to good. The yields of the exo- cyclophanes were better ... -
Protease inhibitors broadly effective against feline, ferret and mink coronaviruses
(Elsevier, 2018-12)Ferret and mink coronaviruses typically cause catarrhal diarrhea in ferrets and minks, respectively. In recent years, however, systemic fatal coronavirus infection has emerged in ferrets, which resembles feline infectious ... -
Protein solvent shell structure provides rapid analysis of hydration dynamics
(American Chemical Society, 2019-03-13)The solvation layer surrounding a protein is clearly an intrinsic part of protein structure-dynamics-function, and our understanding of how the hydration dynamics influences protein function is emerging. We have recently ... -
Protein-protein interaction analysis by nuclear magnetic resonance spectroscopy
(Springer New York, 2015)Nuclear magnetic resonance (NMR) has continued to evolve as a powerful method, with an increase in the number of pulse sequences and techniques available to study protein-protein interactions. In this chapter, a straightforward ... -
Prototyping of poly(dimethylsiloxane) interfaces for flow gating, reagent mixing, and tubing connection in capillary electrophoresis
(Elsevier B.V., 2014-01-10)Integrated microfluidic systems coupled with electrophoretic separations have broad application in biologic and chemical analysis. Interfaces for the connection of various functional parts play a major role in the performance ... -

Putative structural rearrangements associated with the interaction of macrocyclic inhibitors with norovirus 3CL protease
(John Wiley and Sons, 2019-03-18)Human noroviruses are the primary cause of outbreaks of acute gastroenteritis worldwide. The problem is further compounded by the current lack of norovirus-specific antivirals or vaccines. Noroviruses have a single-stranded, ... -
Quantitative assessment of additive leachates in abiotic weathered tire cryogrinds and its application to tire wear particles in roadside soil samples
(Elsevier Ltd, 2023-01-01)Tire and road wear particles (TRWP) are becoming an important research question with potential risks on ecological system. A comprehensive understanding of their detection and quantification in soils are challenged by the ... -
Quasi-layered crystal structure coupled with point defects leading to ultralow lattice thermal conductivity in n-type $CU_{2.83}Bi_{10}Se_{16}$
(American Chemical Society, 2021-10-01)$CU_{2.83}Bi_{10}Se_{16}$ a new n-type thermoelectric material, was synthesized via a high-temperature solid-state routine. The quasi-layered structure features of $CU_{2.83}Bi_{10}Se_{16}$ were established by a comprehensive ... -
Rapid amino acid analysis of beers using flow-gated capillary electrophoresis coupled with side-by-side calibration
(Royal Society of Chemistry, 2017-08-21)Amino acid analysis is an important procedure to measure free amino acids (AAs) in various samples including proteins, blood plasma, urine, foods and beverages. Due to the complexity of these samples, chemical separations ... -
Rapid determination of free prolyl dipeptides and 4-hydroxyproline in urine using flow-gated capillary electrophoresis
(Springer, 2017-12)Unhydrolyzed prolyl hydroxyproline (Pro-Hyp) and total 4-hydroxyproline (Hyp) in urine have been suggested as disease biomarkers for bone turnover and osteoporosis. Here, a rapid method was developed to accurately and ... -
Rapid determination of free prolyl dipeptides and 4-hydroxyproline in urine using flow-gated capillary electrophoresis
(Wichita State University, 2018-04-27)4-hydroxyproline (Hyp) and prolyl dipeptides such as prolyl hydroxyproline (Pro-Hyp) have been found as disease biomarkers in the diagnosis of bone turnover and osteoporosis. To determine these compounds in human urine ... -
Rapid labeling of amino acid neurotransmitters with a fluorescent thiol in the presence of o-phthalaldehyde
(John Wiley & Sons, Inc., 2017-02)LIF detection often requires labeling of analytes with fluorophores; and fast fluorescent derivatization is valuable for high-throughput analysis with flow-gated CE. Here, we report a fast fluorescein-labeling scheme for ... -
