Silica-coated alumina activator-supports, and catalyst compositions containing these activator-supports, are disclosed. Methods also are provided for preparing silica-coated alumina activator-supports, for preparing catalyst compositions, and for using the catalyst compositions to polymerize olefins....
The method utilizes airborne-particle abrasion using particles having a silica surface and an alumina core. The impact of the TSC method has been extensively studied but less attention has been paid to the characterization of the silica-modified alumina particles. Due to the role of silicate ions...

Photodynamic therapy (PDT) has been widely used in the treatment of malignant tumors [17]. The key component of PDT is photosensitizer (PS), which can beactivated by a specific laser to generate highly reactive singlet oxygen (1O2). These singlet oxygen molecules can further destroy cancer cel...
Surface-enhanced Raman scattering (SERS) sensing, based on cubic metal nanoparticles, also benefits from lower index substrates such as glass (n ~ 1.5)3,4 and flower-like alumina-coated etched aluminum foil (n ~ 1.4)5. Plasmonic nanostructures used in optical sensing support quite ...
