  The effects of dc bias voltage on the crystal size and crystal quality. of cBN films

  摘要：

  For the deposition of cubic boron nitride thin films in Ar-N-2-BF3-H-2 system by de jet plasma chemical vapor deposition, the role of dc substrate bias ranging from -70 V to -150V was investigated. A critical bias voltage was observed for the formation of cBN phase. The cBN content in the film increased with bias voltage and reached a maximum at the bias voltage of -85 V. Increasing the bias voltage further caused a decrease in cBN content and peeling of the films from the substrate. By combining the results of infrared spectroscopy Raman spectroscopy and X-ray diffraction, the bias voltage was also found to strongly affect the crystal size, crystal quality and residual stress of the deposited films. A bias voltage a little higher than the critical value was demonstrated to be favorable for the deposition of a high-quality cBN film with large crystal size and low residual stress.

  摘要：

  天然顺式类胡萝卜素联苯胺（甲基氢9'-顺式6、6'-二茂胡萝卜素-6、6'-二酸酯）与玫瑰红孟加拉蓝或亚甲基蓝在乙腈/甲醇（1：1）中的光敏异构化反应使用紫外可见光谱，高效液相色谱（HPLC）和时间分辨光谱技术（例如激光闪光光解和单重态氧磷光检测）对溶液进行了研究。在N（2）和空气饱和溶液中，形成的主要产物都是全反式联鑫。观察到的异构化速率常数k（obs）在空气存在下或随着Bixin浓度的增加而降低，表明Bixin（3）Bix的三重态激发态参与了顺式->反式的前体过程。另一方面，在不存在敏化剂和/或光的情况下，Bixin溶液不会降解，表明Bixin的基态对室温下的热异构化稳定。时间分辨光谱实验证实了联蛋白的激发三重态的形成及其通过基态联蛋白和分子氧猝灭过程的失活。主要的异构化产物仅在空气存在下和长时间的光照条件下降解，这可能是由于与单线态分子氧反应形成了氧化产物。能量传递机制被用来解释观察

  Hydroxylated nebivolol metabolites increase NO release from human endothelial cell preparations in a concentration dependent fashion following acute administration. In addition, hydroxylated nebivolol metabolites, including but not limited to 4-hydroxy-6,6′difluoro-, 4-hydroxy-5-phenol-6,6′difluoro-, and 4-hydroxy-8-pheno-6,6′difluoro-, have the ability to increase the capacity for NO release in human endothelial cells following chronic administration. This invention provides hydroxylated nebivolol metabolites and compositions comprising nebivolol and/or at least one hydroxylated metabolite of nebivolol and/or at least one additional compound used to treat cardiovascular diseases or a pharmaceutically acceptable salt thereof. In addition, this invention provides methods of treating and/or preventing vascular diseases by administering at least one hydroxylated metabolite of nebivolol that is capable of releasing a therapeutically effective amount of nitric oxide to a targeted site affected by the vascular disease. Also, this invention is directed to the treatment and/or prevention of migraine headaches administering at least one hydroxylated metabolite of nebivolol. This invention may also be used in conjunction with or as a single treatment of metabolic syndrome disorders.
