The copper nanoparticles are used in different areas of science and technology because these nanoparticles have good properties because their properties are different from the large material. The copper is a ductile metal with very high thermal and electrical conductivity but the copper nanoparticles are round and look like brown to black powder. The uses of copper nanoparticle are for EMI shielding, metals and high strength alloys, heat sinks and highly thermal conductive materials, etc. The importance for the career is that it broadens the field in which one can perform and as it is a new technology there are still many things to investigate. I chose the copper nanoparticles because my cousin is doing his thesis related to this material so I was reading a bit about these.

I like all animals but as a pet I prefer dogs since I am allergic to cats so I can not have a cat, I have also had birds and hamsters but my favorite is dogs.
