World's most precise clock achieves 19-decimal accuracy with aluminum ion technology by Rebecca Jacobson, National Institute of Standards and Technology ...

The corrosion behavior of polypyrrole on aluminium in sodium chloride medium has been investigated by open circuit potential and electrochemical impedance spectroscopy. A mechanism to explain the ...

The chloride ion flux (J Cl) represents the speed at which the ions are transported through the concrete, and the steady-state and nonsteady-state diffusion coefficients are calculated based on this ...
