A transparent wet gel was obtained in a few minutes at room temperature by adding an aqueous phosphoric acid solution of appropriate concentration to boehmite nanofiber sol. After aging and supercritical carbon dioxide drying, low bulk density aerogels with visible light transmittance over 90% 10 mm thickness were obtained. These exhibited high Young’s modulus transmittance, while having the sa...
A surface-enhanced Raman scattering (SERS) active structure allows the highly sensitive imaging of label-free molecular trace. gold nanostructure with boehmite as a skeleton was fabricated by inclined magnetron sputtering method. The characteristics prepared SERS plate consisting on were evaluated follows. distance dependence intensity 4,4′-bipyridine from edge substrate indicated that larger b...
