Analysis of polyphenols using capillary zone electrophoresis - Determination of the most effective wine sample pre-treatment method
(2010)A simple CZE method has been developed for the simultaneous determination of eight polyphenolic compounds. The influence of several experimental conditions such as buffer (concentration and pH) and temperature were studied. ...

Chiral separations using a polypeptide and polymeric dipeptide surfactant polyelectrolyte multilayer coating in open-tubular capillary electrochromatography
(2004)A polyelectrolyte multilayer (PEM) coating consisting of the polypeptide, poly(L-lysine) hydrobromide, poly(L-lysine) and the polymeric dipeptide surfactant, poly(sodium undecanoyl-L-leutcyl-alaninate), poly(L-SULA), is ...

Evaluation of amino acid ester-based ionic liquids as buffer additives in CE for the separation of 2-arylpropionic acids nonsteroidal anti-inflammatory drugs
(2014)The aim of the present study is the CE performance evaluation for the separation of 2-arylpropionic acid nonsteroidal anti-inflammatory drugs. In particular, the separation of indoprofen, carprofen, ketoprofen, ibuprofen, ...

Open-tubular capillary electrochromatography/electrospray ionization-mass spectrometry using polymeric surfactant as a stationary phase coating
(2004)We describe the use of the polymeric surfactant poly(sodium undecylenic sulfate) (poly-SUS) as a stationary phase coating in open-tubular capillary electrochromatog raphy (OT-CEC) coupled with electrospray ionization-mass ...

Proton binding to proteins: A free-energy component analysis using a dielectric continuum model
(2005)Proton binding plays a critical role in protein structure and function. We report pKa calculations for three aspartates in two proteins, using a linear response approach, as well as a "standard" Poisson-Boltzmann approach. ...

Static tetraquark and pentaquark potentials
(2005)We evaluate the static qq q̄ q̄ and qqqqq̄ potentials in the quenched theory at β = 5.8 and β = 6.0 on a lattice of size 16 3 × 32. We compare the static potentials to the sum of two meson potentials for the tetraquark ...
