ANA IOANID1,*
Electrical double layer (EDL), consists in a shielding layer that is naturally created within the liquid near a charged surface. The thickness of the EDL is given by the characteristic Debye length whole typical value ~1nm depends on the ionic contents in the solvent. The electrokinetic effects in nanochannels depend essentialy on the distribution of charged species in EDL, described by the Poisson-Boltzmann equation those solutions require the solvent dielectric permittivity. A model for solvent low-frequency permittivity profile is proposed, taking into account both the porous silicon (PS) electrode and aqueous solvent properties in the Debye length range.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
