摘要： Mechanochemical fabrication produces electroceramics using oxides as starting materials. The fabrication starts with mixing industrial ceramic oxide powders. Electroceramic phases are formed by reacting the oxide powders in a mechanochemical chamber, which is a wear-resistant cylindrical vial with one or more solid balls inside. The formation of electroceramic phases of pervoskite structure and fine crystallinity are activated by mechanical energy or a combination of mechanical energy and thermal energy. Sintered electroceramic materials and components are fabricated when compacts or green bodies made of the resulting ceramic powders are densified at the sintering temperature. The technique can fabricate a wide range of PbO-based ceramics such as Pb(Mg⅓Nb⅔)O3 (PMN), Pb(Mg⅓Nb⅔) O3-PbTiO3 (PMN-PT), Pb(Mg⅓Nb⅔) O3-Pb(Zn⅓Nb⅔)O3-PbTiO3 (PMN-PZN-PT), and other PMN-based relaxor ferroelectrics, Pb(Zr1−xTix)O3 (PZT) and PZT-based piezoelectrics at sintering temperatures as low as 900° C.

摘要： Heterolayered thin films having ferroelectric/piezoelectric layers of alternating crystal structures and methods of their preparation are provided. In the ferroelectric/piezoelectric thin film, a first layer has a rhombohedral crystal structure and a second layer adjacent the first layer has a tetragonal crystal structure. The layers have a (100) preferred orientation with a-axis normal to the surface of the film. The first layer can be a Zr-rich lead ziroconate titanate layer (e.g. PbZr0.8Ti0.2O3) and the second layer can be a Ti-rich PZT layer (e.g., PbZr0.2Ti0.8O3). Heterolayered ferroelectric/piezoelectric thin film comprising a plurality of such first and second layers in alternating sequence exhibits particularly improved electrical properties.

摘要： A mesoporous, nanocrystalline, metal oxide construct particularly suited for capacitive energy storage that has an architecture with short diffusion path lengths and large surface areas and a method for production are provided. Energy density is substantially increased without compromising the capacitive charge storage kinetics and electrode demonstrates long term cycling stability. Charge storage devices with electrodes using the construct can use three different charge storage mechanisms immersed in an electrolyte: (1) cations can be stored in a thin double layer at the electrode/electrolyte interface (non-faradaic mechanism); (2) cations can interact with the bulk of an electroactive material which then undergoes a redox reaction or phase change, as in conventional batteries (faradaic mechanism); or (3) cations can electrochemically adsorb onto the surface of a material through charge transfer processes (faradaic mechanism).

摘要： A handlebar grip capable of combining with or without an auxiliary handle is disclosed. Four first tongue plates in an annular arrangement extend from a main grip. There is a gap between two adjacent first tongue plates. Each first tongue plate has a first rib extending therefrom. A cap having second tongue plates corresponding to the first tongue plates is fixed on the outer end of the main grip by interlacing the tongue plates. A hitching ring is sandwiched between the cap and main grip to form an extended portion of the main grip. Each the second tongue plate has a second rib, which connects the first ribs to form an annular rib with the first ribs. The ring has an annular groove to receiving the annular rib and to engage the main grip and cap. The ring may be changed into a horn shape as an auxiliary handle.

摘要： A timing-control method of a hardware-simulating program can be applied to a software platform for facilitating control program development. The hardware-simulating program can be recorded in any suitable recording medium and defines therein a plurality of simulating elements which are automatically synchronized at intervals by setting specified time points as aligning points. The specified time points are set with adjustable intervals. By adjusting an interval between adjacent specified time points, the simulating speed between the adjacent specified time points can be changed to comply with practical requirements.
