A hybrid nanogel has been developed based on interpenetrating networks of thermosensitive poly(N-isopropylacrylamide) gels and tailored nanoporous silica. A sustainable positive thermo-responsive drug release profile is obtained. When the temperature rises, the polymer gel shrinks, squeezing the drug into the porous channels, and at the same time, opening… (More)
A new, surface-mediated method to grow transparent, oriented, and well-defined nanocrystalline anatase TiO2 films has been developed. The morphology of crystals is tunable from octahedral pyramids to truncate octahedral pyramids. These novel nanocrystalline films could have implications not only for practical applications but also for understanding the… (More)
The beneficial effects humidity treatments have on molecularly templated mesoporous silica films with respect to elastic modulus, with minimal detrimental effects on porosity and dielectric constant, were identified.
Raman-band intensities for sputter-deposited TiO(2)/SiO(2) multilayer coatings are found to exhibit a strong dependence on excitation wavelength of the probe laser. A model based on standing waves within the stack correctly predicts the magnitude and wavelength dependence of the observed enhancements.
