Chitosan–silica hybrid porous membranes

Characterization of Porous Membranes

Synthesis of Porous Inorganic Membranes

Introduction Here we will attempt a brief overview of recent synthetic efforts for micropore and lower-end mesopore membranes. We will not address the very important classes of nonporous membranes, such as dense metals and solid electrolytes with applications in H2 and O2 separations, or mesoand macroporous mem­ branes, which find applications in food processing and water treatment. Micro­ poro...

Terahertz transmission through p + porous silicon membranes

Electrokinetic and electrochemical characterizations of porous membranes

Surface and bulk membrane have been electrically and chemically characterized by different kinds of measurements. Tangential streaming potential, impedance spectroscopy, membrane potential and salt diffusion were measured with a porous polysulfone membrane for ultrafiltration when it was in contact with NaCl solutions at different concentrations (5×10 c 5×10 M). From these experiments some memb...

Chloride Transport in Porous Lipid Bilayer Membranes

This paper describes dissipative Cl(-) transport in "porous" lipid bilayer membranes, i.e., cholesterol-containing membranes exposed to 1-3 x 10(-7) M amphotericin B. P(DCl) (cm.s(-1)), the diffusional permeability coefficient for Cl(-), estimated from unidirectional (36)Cl(-) fluxes at zero volume flow, varied linearly with the membrane conductance (Gm, ohm(-1).cm(-2)) when the contributions o...
