In-situ infrared spectroscopy studies of surface reactions over irradiated photocatalysts by Gong, Dangguo

“…Commercial material, Degussa P25 TiO2, was used mainly for system verification and fundamental studies on the state of material under bandgap excitation, especially ATR-FTIR, and as a benchmark (in pristine and metalized form) for novel visible-sensitized photocatalysts prepared in this thesis. …”

InAlN/GaN high electron mobility transistors on Si for RF applications by Xing, Weichuan

“…In fact, as the operating frequency increases into the mm-wave range by shrinking the gate length, the linearity is expected to degrade even further. This thesis mainly focuses on these two issues. Novel approaches are employed to resolve them and much improved device performance were obtained. …”

Modélisation des interactions en Italie du Nord au premier âge du Fer: de la circulation de parures aux réseaux d’influences culturelles by Cicolani, V, Huet, T, Zamboni, L

“…The selected data set includes more than 2000 copper-based alloy objects, mainly ornaments and the waste products associated with their production, from both settlements and funerary contexts, well documented and located in southern Piedmont (indigenous communities in Inner Liguria) and western Emilia (indigenous communities in the western sector of the Po valley). …”
