Abstract The feather-like hierarchical zinc oxide (ZnO) was synthesized via successive ionic layer adsorption and reaction without any seed layer or metal catalyst. A possible growth mechanism is proposed to explain the forming process of ZnO feather-like structures. Meanwhile. the photo-electronic performances of the feather-like ZnO have been investigated with the UV-vis-NIR spectro... https://www.majesticmalinois.com/product-category/blood-pressure-monitoring/
