Composite multiferroics containing ferroelectric and ferromagnetic components often have much larger magnetoelectric coupling compared to their single-phase counterparts. Doped or alloyed HfO2-based ferroelectrics may serve as a promising component in composite multiferroic structures potentially feasible for technological applications. Recently, strong charge-mediated at the Ni/HfO2 interface ...

Title of Document: MODEL DEVELOPMENT FOR GADOLINIADOPED CERIA-BASED ANODES IN SOLID OXIDE FUEL CELLS Lei Wang, Doctor of Philosophy, 2014 Directed By: Professor Gregory S. Jackson, Department of Mechanical Engineering Intermediate temperature (500 700 °C) solid oxide fuel cells (IT-SOFCs) with gadolinia-doped ceria (GDC) electrolytes have significant commercial potential due to reduced material...

MEMS gas sensor is one of the development directions of the sensor, and it must work at a certain temperature, so micro heater is an important part of MEMS gas sensor. In this paper, aiming at the high cost and complex process of Pt film heater, we developed the research of Fe/Cr/Al and Ni/Cr cheap metals replacing Pt metal. With Fe/Cr/Al and Ni/Cr metal as the targets respectively, Fe/Cr/Al an...

Carbon nanotubes (CNTs) have high aspect ratio and have great potential to be applied as the field emission cathode because of its large field enhancement factor. In this work, a high performance carbon nanotube field emission cathode (CNTFC) was fabricated by using a composite plating method. The CNTs were purified by acid solutions and then dispersed in electrobath with nickel ions at tempera...
