In this paper, copper suspension colloids were prepared via single chemical reduction method without protective gas. In this procedure, the influence of ascorbic acid (VC) as antioxidant and dispersant dissolved in the aqueous copper colloids on the colloidal stabilization was studied by X-ray diffractometry (XRD), UV-vis spectrophotometer (UV-vis) and transmission electron microscopy (TEM), respectively. The results revealed that VC plays important role of protecting the copper colloids to prevent oxidation and agglomeration, and the VC-protected copper suspension colloids have good stability for application..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
