INTRODUCTION There are different ways of classifying materials
... 1. Metals and alloys: Metals have good electrical and thermal conductivity. Metals and alloys have relatively high strength, high stiffness, ductility or formability, and shock resistance. They are particularly useful for structural or loadbearing applications. Although pure metals are occasionally ...

Resistance of constantan wire
... As you may know the current in a wire is due to the motion of free electrons within the wire. These electrons are not bound to any particular atom but are free to 'wander' through the body of the material. The more free electrons per unit volume the greater the current for a given voltage difference ...

Carbon nanotubes are molecular-scale tubes of graphitic carbon
... nanotubes can also be made by passing a carbon-containing gas, such as a hydrocarbon, over a catalyst. The catalyst consists of nano-sized particles of metal, usually Fe, Co or Ni. These particles catalyse the breakdown of the gaseous molecules into carbon, and a tube then begins to grow with a meta ...
