• dried in the electrothermal oven, and then the dried CNFMs were packed in self-sealing bags for subsequent tests and applications. The growth mechanism of CuO and ZnO nanocrystals on the calcined CNFMs using hydrothermal synthesis is as follows. When C6H12N4 is added to the solution, a large amount of

• evolution, plants evolved various reactions to wounding. Fast wound sealing and subsequent healing represent a selective advantage of particular importance for plants growing in arid habitats. An effective self-sealing function by internal deformation has been found in the succulent leaves of Delosperma
