含Mn中间层钛基二氧化锡电催化电极的性能

采用高温热氧化方法制备了含Mn中间层的钛基二氧化锡电催化电极Ti/Mn/SnO2.采用SEM、EDX以及XPS等检测方法对电极表面涂层的形貌、元素组成及元素化学态进行了分析,研究了所制备Ti/Mn/SnO2电极电催化氧化降解苯酚的性能.结果表明,Mn中间层的引入降低了电极对苯酚的电催化降解活性,使电极的使用稳定性大为提高.含Mn中间层的存在,可防止电化学反应过程中析出的氧向基体的扩散,离子对Mn2 /Mn4 与Sn2 /Sn4 的存在改变了SnO2电极表面催化剂的组成和结构,导致电极性能变化.

Remembering the Good, Forgetting the Bad: Intentional Forgetting of Emotional Material in Depression.

The authors examined intentional forgetting of negative material in depression. Participants were instructed to not think about emotional nouns that they had learned to associate with a neutral cue word. The authors provided participants with multiple occasions to suppress the unwanted words. Overall, depressed participants successfully forgot negative words. Moreover, the authors obtained a clear practice effect. However, forgetting came at a cost: Compared with the nondepressed participants and with the depressed participants who were instructed to forget positive words, depressed participants who were instructed to forget negative words showed significantly worse recall of the baseline words. These results indicate that training depressed individuals in intentional forgetting could prove to be an effective strategy to counteract automatic ruminative tendencies and mood-congruent biases.
