    摘要： Epitaxial thin films for use as buffer layers for high temperature superconductors, electrolytes in solid oxide fuel cells (SOFC), gas separation membranes or dielectric material in electronic devices, are disclosed. By using CCVD, CACVD or any other suitable deposition process, epitaxial films having pore-free, ideal grain boundaries, and dense structure can be formed. Several different types of materials are disclosed for use as buffer layers in high temperature superconductors. In addition, the use of epitaxial thin films for electrolytes and electrode formation in SOFCs results in densification for pore-free and ideal grain boundary/interface microstructure, Gas separation membranes for the production of oxygen and hydrogen are also disclosed. These semipermeable membranes are formed of high-quality, dense, gas-tight, pinhole free sub-micron scale layers of mixed-conducting oxides on porous ceramic substrates. Epitaxial thin films as dielectric material in capacitors are also taught herein. Capacitors are utilized according to their capacitance values which are dependent on their physical structure and dielectric permittivity. The epitaxial thin films of the current invention form low-loss dielectric layers with extremely high permittivity. This high permittivity allows for the formation of capacitors that can have their capacitance adjusted by applying a DC bias between their electrodes.

    摘要： A high intensity and high efficiency radiant gas burner (10) has a housing (8), a gas inlet (11) for receiving a combustible gas, a gas injection plate (13) for distributing the gas, a gas distribution chamber (16) for permitting the gas to expand, a porous ceramic layer (17) for receiving the gas from the gas distribution chamber (16), and a plurality of elongated flame support rods (23) situated over and spaced from a burner surface (17b) of the porous ceramic layer (17). When the gas is ignited, the flame transfers energy via convective heat transfer to the rods (23). When the rods (23) heat up, they radiate energy back towards the burner surface (17b) and also outwardly away from the burner surface (17b) so that radiation intensity and efficiency are optimized. A rod adjustment mechanism (84) may be disposed on the burner (10) for moving the rods (23) to thereby optimize radiation intensity and efficiency. Moreover, a temperature sensor may be disposed within a rod (23) for monitoring the temperature of the flame support rod structure (81). The temperature signal (82) can be used to control the position of the rods (23) via the rod adjustment mechanism (84) and/or a gas adjustment mechanism (88) for manipulating the rate or contents of the combustible gas.
