Confined crystallization of fenofibrate in nanoporous silica.
Producing stable nanocrystals confined to porous excipient media is a desirable way to increase the dissolution rate and improve the bioavailability of poorly water soluble pharmaceuticals. The poorly soluble pharmaceutical fenofibrate was crystallized in controlled pore glass (CPG) of 10 different pore sizes between 12 nm and 300 nm. High drug loadings of greater than 20 wt% were achieved acro...
متن کاملEletrowetting effect in a nanoporous silica.
In the past, electrowetting was usually analyzed on large solid surfaces. In the current study, the effective solid-liquid interfacial tension in a nanoporous silica, which is measured by the ion transport pressure, is investigated experimentally. The interfacial tension decreases as the applied potential difference increases, while the magnitude of variation is much smaller than its bulk count...
متن کاملWater confinement in nanoporous silica materials.
The influence of the surface polarity of cylindrical silica nanopores and the presence of Na(+) ions as compensating charges on the structure and dynamics of confined water has been investigated by molecular dynamics simulations. A comparison between three different matrixes has been included: a protonated nanopore (PP, with SiOH groups), a deprotonated material (DP, with negatively charged sur...

Title of Dissertation: IMMOBILIZATION OF ENZYMES ON NANOPOROUS SILICA COMPOSITES Allan E. David, Ph.D., 2004 Dissertation Directed By: Associate Professor N.S. Wang, Department of Chemical Engineering Dr. A.J. Yang, ISTN, Inc. In this work, the sol-gel process is used to produce a chemically surface modified gel (CSMG) with a high modification density. Sodium silicate, an inexpensive alternativ...
متن کاملDistinctive electrokinetic behavior of nanoporous silica particles treated with cationic polyelectrolyte
In this study we show, for the first time, that the streaming potential of aqueous suspensions of nanoporous silica gel, after treatment with the ationic polyelectrolyte poly-diallyldimethylammonium chloride (poly-DADMAC), can depend very strongly on the concentration of background lectrolyte. An increase in the electrical conductivity from 60 to 1000 S/cm resulted in an approximately 1000-fold...
