Sulfite-sensitive solvent/polymeric-membrane electrode based on bis(diethyldithiocarbamato)mercury(II)
(Elsevier, 1989)
A new solvent/polymeric-membrane electrode which exhibits significant potentiometric response toward sulfite ion in the 1 x 10-6-1 x 10-3 M range is described. The membrane is prepared by incorporation of neutral ...
Proteomic analysis of estrogen response of premalignant human breast cells using a 2-D liquid separation/mass mapping technique
(WILEY-VCH Verlag, 2006-07)
A 2-D liquid-phase separation method based on chromatofocusing and nonporous silica RP-HPLC followed by ESI-TOF-MS was used to analyze proteins in whole cell lysates from estrogen-treated and untreated premalignant, ...
Determination of Α-helix and Β-sheet stability in the solid state: A solid-state NMR investigation of poly( L -alanine)
(Wiley Subscription Services, Inc., A Wiley Company, 2002-08-15)
The relative stability of Α-helix and Β-sheet secondary structure in the solid state was investigated using poly( L -alanine) (PLA) as a model system. Protein folding and stability has been well studied in solution, but ...
Ultrafast X-ray Absorption Spectroscopy Reveals Excited State Dynamics of B12 Coenzymes Controlled by the Axial Base
(American Chemical Society, 2023-11-23)
Polarized time-resolved X-ray absorption spectroscopy at the Co K-edge is used to probe the excited state dynamics and photolysis of base-off methylcobalamin and the excited state structure of base-off adenosylcobalamin. ...
Watching Excited State Dynamics with Optical and X-ray Probes: The Excited State Dynamics of Aquocobalamin and Hydroxocobalamin
(American Chemical Society, 2023-06-16)
Femtosecond time-resolved X-ray absorption (XANES) at the Co K-edge, X-ray emission (XES) in the Co Kβ and valence-to-core regions, and broadband UV–vis transient absorption are combined to probe the femtosecond to picosecond ...
