摘要： A device and method for flash evaporating a reagent includes an evaporation chamber that houses a dome on which evaporation occurs. The dome is solid and of high thermal conductivity and mass, and may be heated to a temperature sufficient to vaporize a specific reagent. The reagent is supplied from an external source to the dome through a nozzle, and may be supplied as a continuous stream, as a shower, and as discrete drops. A carrier gas may be introduced into the evaporation chamber and create a vortex flow therewithin. After evaporation, the gas vapor may be removed from the evaporation chamber through a regulating valve to a reaction chamber. Another embodiment of the invention includes a plurality of evaporating domes that separately receive reagent, and may receive reagents of differing composition.

摘要： UV absorbing glass is prepared by mixing ultrafine colloidal cerium oxide with glass-forming substances during the fabrication of the glass. An aqueous colloidal dispersion containing 1-20 weight percent 10-20 nm cerium oxide particles, optionally including a binder, is admixed with silica sand, and the sand is dried, melted and cooled to give a relatively clear UV absorbing glass containing 0.3-2 weight percent cerium oxide.
摘要翻译：通过在制造玻璃时将超细胶体氧化铈与玻璃形成物质混合来制备紫外线吸收玻璃。将包含1-20重量％的10-20nm氧化铈颗粒（任选地包括粘合剂）的水性胶体分散体与硅砂混合，并将砂干燥，熔融并冷却，得到相对清晰的含有0.3-2 重量百分比的氧化铈。

摘要： A ferroelectric capacitor used as a memory cell in a ferroelectric random access memory (FRAM) is provided. The ferroelectric capacitor includes a substrate, an insulating layer formed on the substrate, a Rh lower electrode provided on the insulating layer, an adhesive layer between the insulating layer and the lower electrode, a ferroelectric layer provided on the lower electrode, and a Rh upper electrode provided on the ferroelectric layer. The Rh used as the electrode material is not affected by diffusion of Si due to its fine structure when compared to a Pt electrode, and has excellent electrical properties due to better electrical conductivity and good heat-transfer properties.
摘要翻译：提供了用作铁电随机存取存储器（FRAM）中的存储单元的铁电电容器。铁电电容器包括基板，形成在基板上的绝缘层，设置在绝缘层上的Rh下电极，绝缘层和下电极之间的粘合层，设置在下电极上的铁电层，以及Rh上电极设置在铁电层上的电极。与Pt电极相比，用作电极材料的Rh不受其精细结构的Si的扩散的影响，并且由于更好的导电性和良好的传热性能而具有优异的电性能。
