nanocomposite membranes with cloisite and bentonite are being suggested to be a promising proton exchange membrane for direct methanol fuel cell. ...
but also can make the proton exchange membrane electrolysis cell (PEMEC) reach steady state rapidly, resulting in overheat and unsafe operation. The operation strategy changing the water supply mode ...
The two‐ phase flow behaviors in a proton exchange membrane fuel cell with orientated‐type flow channels are monitored through the side‐view direction , and the changing behaviors of cell performance ...
and evaluated as proton exchange membranes for direct methanol fuel cells (DMFCs). The structure of PMFP‐g‐PS was characterized by Fourier transform infrared spectroscopy, 1H and 19F NMR spectra. In comparison ...
and oxidative stabilities. Transmission electron microscopy (TEM) observation showed clear phase ‐separated structures resulting from the difference in polarity between the hydrophobic polyphosphazene backbone ...
directions C. Allen Chang ,*a,c Hwa Yu Leea and Cheng-Lung Chenb The prediction of conformations and protonation sites for the macrocyclic ligands H2DO2A (1,4,7,10tetraazacyclododecane-1,7-diacetic acid ...
compartments and slow water exchange . Our model reproduces the signal changes observed in ischemia via physiologically credible mechanisms. Conclusion Our modeling suggests that transverse relaxation has ...
°. The strength of residual dipolar interactions between water protons was estimated by orientational analysis of the signal intensity to be equal to 780 Hz. Apparent signal maxima are observed at orientations 8–13 ...
Lanthanide‐binding tags (LBTs), peptide‐based coexpression tags with high affinity for lanthanide ions, have previously been applied as luminescent probes to provide phasing for structure ...
to a Hoogsteen (HG) base pair (13). The hydrogen bond break permits 1H exchange (which can be experimentally observed ) between water and the imino proton in thymine and guanine, even if the WC base pair is simply ...
