Most polymers -- materials made of long, chain-like molecules -- are very good insulators for both heat and electricity. But scientists have now found a way to transform the most widely used polymer, ...

Plastics are excellent insulators, meaning they efficiently trap heat—a quality that is an advantage in something such as a coffee cup sleeve. But this insulating property is less desirable in ...

The performance of an object that has been dependent upon whether the object is composed of a conductive or a nonconductive material. Conductors are materials that allow electrons to flow freely from ...

Sometimes we want to heat things up - like these beans. Oh, wait. Hang on. You need to put the beans in something first. But what should it be made of? Wood? Plastic? Or metal? The metal saucepan is ...

Is your laptop or phone overheating? Newly engineered plastic could lead to self-cooling casings for common electronics. Plastics are excellent insulators, meaning they can efficiently trap heat -- a ...

Over the years, Hendrix has maintained that porcelain insulators (and porcelain spacers) should not be used with covered conductor. This is due to the dielectric incompatibility between the two ...

University of Cambridge researchers have discovered that a material already known for its peculiar electrical properties appears to behave as both a conductor and an insulator at the same time. This ...

Graphene is widely seen as the most-promising candidate to replace silicon as the building block of ever-smaller, more-complex, and more-numerous transistors. To speed that transition along, engineers ...

CAMBRIDGE, MASS.--Plastics are excellent insulators, meaning they can efficiently trap heat - a quality that can be an advantage in something like a coffee cup sleeve. But this insulating property is ...

We’re surrounded by electrically powered devices these days. From our lights, to our kettles, and of course our phones! Electricity flows through copper or aluminium wire to power or charge all of ...
