In Situ FT-IR Studies of Oxide and Oxynitride Sol-Gel-Derived Thin Films
A high-temperature infrared cell was developed to study the gel-to-glass conversion of sol-gel-derived thin films. FT-IR spectra of matched thin-film borosilicate sol-gel samples were taken as the samples were...

A Novel Design Toward Understanding and Characterizing Transport Behavior of Composite Mesoporous Silica Thin Films
In this paper, we for the first time apply a so-called “bottom-up” approach in fabricating synthetic ion-channel by exploiting evaporation-induced self-assembly (EISA) to form highly ordered porous thin film s...
