can we get thin copper found in used cables,electronic stuffs, to better use by recycling it?

Copper in cables can certainly be recycled, and fetches quite a good price. You'd need to collect a reasonable weight of it though, strip off the insulation, then take it to a scrap metal dealer to have it weighed in.

research is currently being carried out on this area. materials which work better at room temperature and have similar properties to a semi conductor are already being developed. giveit another 25-30 years we may have some. who knows.....

copper. because it can oxidize easier. That is why statue of liberty is green.

Copper in chips and diamonds in drives lead to a shiny future.\n\nThis is one nice article.

Buy a new one, get the old out, put the new in.  It's easy methods, just be careful in connecting the power and cable.

call your local waste authority to see where you can take idems like that.  There are usually several businesses around that will take older hardware and make it new for other people in need to use.  It was very nice to think about something like that. :D

Maybe by going to your recycling bin.( if you have one)

Copper is used as a conductor and as a easily maliable (formable) metal.  It is also naturally anti-bacterial.

it's silver. it used to be used in telegraph/telephone wires, but when the poles got knocked down by storms, people would pull out miles of the silver wire and sell it to jewelers and pawn shops. that's why they switched to copper: it is the most conductive, non-precious metal.

I once read about a device with which reconditioning may be achieved 90% of the time on some types of batteries by applying a very brief, high voltage pulse (kinda like a camera's flash system) across the terminals of individual rechargeable cells.  I tried an improvised version of it with NiCD and sealed lead batteries, and it seemed to work most of the time.  I couldn't find plans for the device when I searched just now, though, so I can't really tell you more than that.  Unless you're knowledgeable in the field of electronics, I suggest you just get another battery because the method of recycling I just described may be dangerous.

Pennies from 1980/81 and before are already pure copper, so no work would be necessary, other than cleaning them.  New pennies are copper-plated zinc.  A simple way to extract the copper is to make a gash in the side of the penny, then drop the penny in some hydrocholoric acid.  The HCL will react with the zinc to form zinc chloride (expelling hydrogen gas), but will not react with the copper.  This will leave you with a thin copper shell (FYI, this is a common high school/general chemistry experiment).  It is actually a fairly cool experiment.
