. FS lap welding using intermediate layer is also found effective during joining of Al-Cu. Use of a new anodized material Al-MIL-A-8625F containing coating of anodic sulfur with a layer of 23 mm-thick......
section. Improvement in thermal performance was the result of changes in thermophysical properties and coating layer existence. Obtained results for the heat transfer coefficient improvement at the mass......
cost needed, which are severely against applications. On the other hand, the solution process approach proves to be more efficient by the use of methods like coating or printing which are highly cost......
forces from rock blocks. Cutters today can either incorporate hard, fine grained carbides into the matrix of the disc material or apply a hardened coating of alloy powder on the steel substrate......
平面异质结结构类似,但在致密层上制备了介孔层,致密层与介孔层共同作为电子传输层,介孔层同时为钙钛矿的生长提供了支撑层,常用介孔层材料为二氧化钛(TiO2),二氧化锡(SnO2).单基板三层介孔薄膜结构由染料敏化太阳能电池发展而来,钙钛矿晶粒附着在介孔层颗粒上,接触面积得到大幅度增加.三层介孔层通常由TiO2介孔层,氧化锆(ZrO2)介孔层,多孔碳层组成,ZrO2层作为绝缘层隔离TiO2与碳层.为防...](a);狭缝喷涂法[73](b);卷对卷工艺[74](c) Fig. 10 Schematic illustration of diverse methods for perovskite solar cells, including one-step spin-coating method, two-step spin-coating method, sequential......
