The copper powder produced by electrolysis has a dendritic structure, which gives it excellent green strength as a raw material for producing powder metallurgical components.Yet its large specific surface makes it susceptible to oxidation.Although the oxidation tends to occur only on the surface, it still needs to be reduced.The partially oxidized
Abstract The occurrence of whole-genome duplication or polyploidy may promote plant adaptability to harsh environments.Here, we clarify the evolutionary relationship of eight GhCIPK6 homologous genes in upland cotton (Gossypium hirsutum).Gene expression and interaction analyses indicate that GhCIPK6 homologous genes show significant functional chan
