Submitted for the MAR13 Meeting of The American Physical Society Control ion transport by tuning the crystalline morphology in polyethylene oxide-based solid electrolyte SHAN CHENG, CHRISTOPHER LI, DERRICK SMITH, Drexel University — The crystalline structure of polyethylene oxide (PEO) strongly affects the ion transport in solid PEO-Lithium salt electrolytes. Four possible phases can exist in a...

Thermal transport in carbon nanotube (CNT) mats, consisting of randomly networked multi-walled carbon nanotubes (MWNTs), is not as efficient as in an individual CNT because of the constrained tube-to-tube phonon transport. Through experiments and modeling, we discover that phonon transport in CNT mats is significantly improved by ion irradiation, which introduces inter-tube displacements, actin...

The equivalent conductivity of molten salts containing more than two ion constituents will be discussed using the equivalent fractions (Äquivalentanteile). The ionic conductivities of the ion constituents follow from this equivalent conductivity and the transport numbers. The electrical transport phenomena are referred to the idealized ionic melt which is defined by the limiting values of the i...

Compared to ion pumps and carriers, ion channels have been quite late recognised as individual transport identities in red blood cells. Here the transition from cell population based flux experiments to single cell based patchclamp investigations are described in detail. The present knowledge of cation channels in red blood cells from their molecular identity to their electrophysiological prope...

J, Physiol. 220(6): 1734-1738. 197 1 .-Isolated winter flounder small intestine mounted in an Ussing chamber and bathed on both sides with teleost fish Ringer solution showed a PD ranging from 1 to 5 mv, with the serosa being electronegative to the mucosa. When the...

Porous membranes with ultrafast ion permeation and high ion selectivity are highly desirable for efficient mineral separation, water purification, and energy conversion, but it is still a huge challenge to efficiently separate monatomic ions of the same valence and similar sizes using synthetic membranes. We report metal organic framework (MOF) membranes, including ZIF-8 and UiO-66 membranes wi...

The crystal structures of channels and transporters reveal the chemical nature of ion-binding sites and, thereby, constrain mechanistic models for their transport processes. However, these structures, in and of themselves, do not reveal equilibrium selectivity or transport preferences, which can be discerned only from various functional assays. In this Review, I explore the relationship between...
