The ion conductivity of two series of porous ceramic diaphragms impregnated with caustic potash was investigated by electrochemical impedance spectroscopy. To understand the impact of the pore structure on ion conductivity, the three-dimensional (3-D) pore geometry of the diaphragms was characterized with synchrotron x-ray absorption tomography. Ion migration was calculated based on an extended...

Spatial SPION localization in liposome membranes

Bonnaud, Cécile ; Vanhecke, Dimitri ; Demurtas, Davide ; Rothen-Rutishauser, Barbara ; Petri-Fink, Alke

In: IEEE Transactions on Magnetics, 2012, vol. 49, no. 1, p. 166-171

Nanocarriers, including liposomes, offer great opportunities for targeted and controlled therapy. The development in this field has led to a large panel of drug delivery systems, which can be classified into 3 different nanovector generations. However, the success of such smart materials requires the control of a large variety of properties and parameters. Unfortunately, characterization at the...
