Studies from Changchun Institute of Applied Chemistry Provide New Data on Crystal Growth

By a News Reporter-Staff News Editor at Health & Medicine Week -- Researchers detail new data in Crystal Growth. According to news reporting originating in Changchun, People's Republic of China, by NewsRx journalists, research stated, "Gold nanostructures with different morphologies are synthesized by an electrochemical deposition method using a sacrificial cathode electrode. The formation of the gold nanostructures involves both a chemical reduction process by self-sacrifice of the electrode and an electrochemical reduction process by the electrons from electrochemical system."

The news reporters obtained a quote from the research from the Changchun Institute of Applied Chemistry, "Gold nanostructures have been facilely tailored as corallines of nanodendrites, nanoplates and nanosheets by controlling the two processes through changing the current density and the concentration of electrolyte solution. On the basis of chemical bonding theory of single crystal growth, preferential growth along (100) directions results in the formation of gold nanodendrites. Nanodendrites are formed when the electrochemical process dominates the reduction process under large current density, which induces the electric convection and cation concentration convection of the growing interface. The nanodendrites with a diameter of 100 nm are cross-linked in a plane forming layered porous coralline structures. Nanosheets are deposited when the chemical reduction process dominates the reduction process under low current density."

According to the news reporters, the research concluded: "The present strategy can provide an effective route to study the dendrite crystal growth for fcc-structured metals."
