If you've ever wiggled a balloon against your hair, you know that rubbing together two different materials can generate static electricity. But rubbing bits of the same material can create static, too. Now, researchers have shot down a decades-old idea of how that same-stuff static comes ...

Most electronic ink and paper screens use a technology calledelectrophoresis, which sounds complex but simply means usingelectricityto move tiny particles (in this case ink) through a fluid (in this case aliquidor gel). Other uses of electrophoresis include DNA testing, where electricity is used ...
Yes, it can be confusing. There are a ton of digital photography definitions used on websites, in photography books, and in digital camera manuals. You try to get through an explanation of a concept and a photography term gets in the way. These definitions are simplified so that you can ...
Pure water appears blue due to the absorption of light in the (electromagnetic wavelength) range of 600 to 800 nanometers. And since it contains no ionic materials or impurities, it’s a bad conductor of electricity. However, its electrical conductivity can be increased by dissolving substances ...
Briefly, it's super-strong and stiff, amazingly thin, almost completely transparent, extremely light, and an amazing conductor of electricity and heat. It also has some extremely unusual electronic properties.General propertiesGraphene is an amazingly pure substance, thanks largely to its simple, ...

Electricity provides energy to strip electrons away from neon atoms, ionizing them. Ions are attracted to terminals of the lamp, completing the electric circuit. Light is produced when neon atoms gain enough energy to become excited. When an atom returns to a lower energy state, it releases a...
