Strength is considered to be the most significant and fundamental properties of any material, it is the measure of basic ability to bear the load. History depicts, how the usage of strong materials has assisted in the development of various technological advances leading to the formation of faster, smaller, lighter and robust equipments. Recent innovations in the field of nanotechnology have given this development a new direction, where devices can be crafted using materials that measure down to nanometers.

The Mighty Power of Gold Nanowires

For incorporating nanotechnology with industrial applications, scientists developed a technique termed as "welding nanowires". In this method, a nano wire made from sacrificial metal is fixed at the place where it must be joined (with the help of manipulators such as scanning electron microscope) after that electric current passes through them, so that both the ends of the wire are fused.

This technique can be useful for fusing wires which are even 10 nm small. Because of the small size, precise control of heating becomes important or else it would damage the nanowire. This is where gold nanowires come for the rescue. Researchers discovered that ultrathin single crystalline gold nanowire that has a diameter of 4-10nm can be welded within in seconds through "cold welding" technique.

This was only possible because of the electrical conductivity and strength of gold nanowires which resulted into faster surface diffusion. The processes can even be carried out in room temperature indicating a new phase in micro-fabrication and nanotechnologies.

Is Strength Influenced By High Quality Gold Nanowires?

Without a doubt, the strength of these nanowires is strongly influenced by their quality. This is the reason why experts emphasize on the method of synthesis when you are looking to purchase high quality gold nanowires, so as to examine its properties for your research work.
