[12] Bearing in mind that graphene is also an amazing conductor of electricity, you can start to understand why people who make solar panels, LCDs, and touchscreens are getting very excited: a material than combines amazing transparency, superb electrical conductivity, and high strength is a ...
AFMs don't suffer from this problem because, although they use still tuneling, they don't rely on a current flowing between the specimen and a probe, so we can use them to make atomic-scale images of materials such as plastics, which don't conduct electricity. Photo: A typical atomic ...
Once that's done, it can be electroplated just like a metal. Depending on how much wear and tear the plated part has to withstand, the coating can be anything from about 10–30 microns thick.Why use electroplating?Photo: This car wheel is made from aluminum metal plated with nickel in ...
Think of cloud computing as renting a fully serviced flat instead of buying a home of your own. Clearly there are advantages in terms of convenience, but there are huge restrictions on how you can live and what you can alter. Will it automatically work out better and cheaper for you in t...
The electrical charge that ions have can be useful in all sorts of ways. Ions (as well as electrons) help to carry the electricity through batteries when you connect them into a circuit. How many atoms are there in something? If atoms are so tiny, there must be zillions and zillions of...
If your heating bills are really starting to get to you, or your home is so old and drafty that you simply can't keep heat in it for any length of time, why not shift your focus away from heating the building to keeping your own body warm? Use a moderate amount of heating each da...
