nanostructured ionic conductors a study of vycor 7930 lii composites
Materials Science and Engineering B-advanced Functional Solid-state Materials, 2008Co-Authors: Stéphanie Albert, Annie Pradel, Nathalie Frolet, Michel RibesAbstract:Abstract A series of three Vycor glass/LiI composites were prepared by impregnating molten LiI into a porous Vycor ® 7930 powdered glass. X-ray diffraction showed the presence of LiI and LiI, H 2 O crystallites of about 100 nm in size. Scanning electron microscopy confirmed that an optimisation of heat treatment could lead to a composite with optimal coating and filling of the pores of the matrix. An increase in the pore size, unavoidable and due to the Residual Water Content of the Vycor, was measured by Hg porosimetry. Nevertheless the conductivity of the composites was increased compared to that of pure LiI, with a gain of two orders of magnitude for the best conductor, i.e. 0.5LiI–0.5Vycor.

Importance of dynamic surface tension to the Residual Water Content of fabrics
Langmuir, 2005Co-Authors: Daniel L. Carter, Matthew C. Draper, Rachel N. Peterson, Dinesh O. ShahAbstract:At the end of the final spin cycle of the laundry process, the Residual moisture Content (RMC) of fabric is directly related to the dynamic surface tension of the Residual Water in the fabric. The LaPlace equation for capillary rise predicts that the capillary rise of solutions in a capillary is proportional to the surface tension at the air-liquid interface. If fabric can be considered to be a large ensemble of capillaries due to interfiber spacing, then the RMC of fabrics will be directly related to the surface tension of Residual solution in the fabric. The use of a tailored rinse additive has the potential to decrease the surface tension of solution significantly, thus leading to a decrease in the Residual Water Content of the fabric. It is expected that as the surfactant concentration increases the surface tension decreases. Hence, the RMC of fabrics must decrease with increasing surfactant concentration. However, a peak is observed in the RMC of fabrics before the critical micelle concentration (CMC) is reached. Prior to the CMC, it is proposed that a sudden adsorption of surfactant is occurring on the fabric surface leading to a decrease in bulk monomer concentration. The decrease in free monomer concentration should result in an increase in the equilibrium surface tension of the Residual solution leading to a concomitant increase in RMC. Because the dynamic surface tension is measured on a short time scale (on the order of milliseconds), there will be less adsorption of monomer onto the newly created air-liquid interface of the bubbles during the measurement process. This decrease in adsorption should lead to a pronounced increase in the dynamic surface tension. This indeed was observed. The RMC correlates very well with the dynamic surface tension of the Residual solution.

The role of surface tension on the Residual Water Content of fabrics
Journal of Surfactants and Detergents, 2005Co-Authors: Daniel L. Carter, Dinesh O. ShahAbstract:Cotton has been shown to hold up to 80% of its initial weight in Water due to strong capillary forces after washing. According to the LaPlace equation for capillary rise, the rise is proportional to the surface tension of the air-liquid interface. The use of a tailored rinse additive has the potential to alter the surface tension of solutions significantly, thus lead- ing to a lower capillary rise. This lower rise can be related to the Residual Water Content in fabrics. The reduction of surface tension lowers the force required to displace liquid inside the capillaries formed by fabric fibers. If the amount of Residual Water in fabrics can be significantly lowered, the drying time of the fabrics would be decreased as well. We have shown that by reducing the surface tension of solutions, the Residual moisture Content of fabrics also decreases. Paper no. S1429 in JSD 8, 91-94 (January 2005).
