An anode is an electrode of a polarized electrical device through which conventional current enters the device. This contrasts with a cathode, an electrode...

The process is called anodizing because the part to be treated forms the anode electrode of an electrolytic cell. Anodizing increases resistance to...

A galvanic anode, or sacrificial anode, is the main component of a galvanic cathodic protection system used to protect buried or submerged metal structures...

An anode ray (also positive ray or canal ray) is a beam of positive ions that is created by certain types of gas-discharge tubes. They were first observed...

An anode-free battery (AFB) is one that is manufactured without an anode. Instead, it creates a metal anode the first time it is charged. The anode is...

materials. The basis of all these is still using two electrodes, anodes and cathodes. 'Anode' was coined by William Whewell at Michael Faraday's request,...

grid) is inserted between the cathode and the anode, the flow of electrons between the cathode and anode can be regulated by varying the voltage on this...

be protected to a more easily corroded "sacrificial metal" to act as the anode. The sacrificial metal then corrodes instead of the protected metal. For...

Anodic bonding is a wafer bonding process to seal glass to either silicon or metal without introducing an intermediate layer; it is commonly used to seal...

cathode of the tube to release electrons, which are accelerated toward the anode and produce X-rays when they strike it. The Crookes tube was improved by...
