2 You can also create a very thin film using the same process that is used to produce silverware.
3 Teapots are electroplated with a thin layer of silver to give them an attractive finish. Objects that are electroplated are first cleaned, then placed in a bath that contains ions, or positively charged atoms, of the metal that will be deposited on them
5 Electroplating a Thin Film The components of an electroplating circuit are at the center of each table.Carefully put the electrodes into the solution of zinc nitrate.Turn the switch on to start the electroplating process.Stop electroplating when the copper electrode seems to be covered with zinc.Put the electrodes on a paper towel at the center of the table.
7 Amount of DepositionThe number of zinc ions that become atoms depends on the number of electrons that pass through the circuitZn2+2e-ammeterI
8 Why choose electroplating to make nanostructures?? The process is easy to operate and only needssimple equipment.It’s simple to control the deposition rate bycontrolling the voltage or current.It’s a good way to make Nanowires in a porous template.

10 If the nanowires are magnetic, they can be used to store data Data storage elementsApplication(arrow indicates the direction of magnetization)
