Ion Transport in Mesoporous Silica SBA-16 Thin Films with 3D Cubic Structures.
Summary of "Ion Transport in Mesoporous Silica SBA-16 Thin Films with 3D Cubic Structures."
Mesoporous silica SBA-16 thin films with highly ordered 3D cubic structures were synthesized on a Si substrate via the dip-coating method. After these films were filled with KCl aqueous solutions, the ionic current passing through the mesopores was measured by applying dc electric fields. At low ion concentrations, the measured I-V curves were nonlinear and the current increased exponentially with respect to voltage. As the ion concentration increased, the I-V curve approached linear behavior. The nonlinear behavior of I-V curves can be reasonably attributed to the electric potential barrier created in nanopores.

Medical and Biotech [MESH] Definitions
Chromatography, Thin Layer
Chromatography on thin layers of adsorbents rather than in columns. The adsorbent can be alumina, silica gel, silicates, charcoals, or cellulose. (McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed)
Instructional Films And Videos
Works consisting of nonfiction films and video designed to teach, instruct, or train. (From Moving Image Materials: Genre Terms, 1988)
Silica Gel
A non-crystalline form of silicon oxide that has absorptive properties. It is commonly used as a desiccating agent and as a stationary phase for CHROMATOGRAPHY. The fully hydrated form of silica gel has distinct properties and is referred to as SILICIC ACID.
Intracellular Membranes
Thin structures that encapsulate subcellular structures or ORGANELLES in EUKARYOTIC CELLS. They include a variety of membranes associated with the CELL NUCLEUS; the MITOCHONDRIA; the GOLGI APPARATUS; the ENDOPLASMIC RETICULUM; LYSOSOMES; PLASTIDS; and VACUOLES.
Documentaries And Factual Films
Works consisting of films, videos, and programs which depict actual persons or actual events. They do not include frank historical re-creations and do not attempt to judge the truth of the depiction in a film purporting to be factual or documentary in character. (From Moving Image Materials: Genre Terms, 1988)
