    摘要:A compound comprising one or more polyfunctionalized pyrrolyl anions coordinated to a metal selected from the group consisting of barium, strontium, magnesium, radium or calcium or mixtures thereof. Alternatively, one anion can be substituted with and a second non-pyrrolyl anion. n Synthesis of the novel compounds and their use to form BST films is also contemplated.

    摘要:A system, apparatus and method are provided for processing articles. The system includes subsystems for synthesizing, pre-treating, conducting a vapor phase coating process and post-treating articles in the form of powders and solid or porous workpieces. The apparatus permits vapor phase synthesis, treatment and deposition processes to be performed with high efficiency and at high overall throughput. The methods include converting solids, liquids or gases into gaseous and solid streams that can be separated or exchanged with or without treatment and/or coating steps, and produce optimized composite articles for specific applications.
