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...

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...

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...

electrolyte), a lithium cobalt oxide (LiCoO 2) cathode material, and a graphite anode, which together offer high energy density. Lithium iron phosphate (LiFePO...

electron-emitting cathode and an anode. Electrons can flow in only one direction through the device – from the cathode to the anode. Adding one or more control...

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...

precisely, the anode heel effect is a variation of the intensity of X-rays emitted by the anode depending on the direction of emission along the anode-cathode...

iron, oxidation takes place and that spot behaves as an anode. The electrons released at this anodic spot move through the metal to another spot on the object...

for an accelerated attack on the anode metal, which dissolves into the electrolyte. This leads to the metal at the anode corroding more quickly than it...

Conductive anodic filament, also called CAF, is a metallic filament that forms from an electrochemical migration process and is known to cause printed...

is a solution of a salt whose cation is the metal to be coated, and the anode (positive electrode) is usually either a block of that metal, or of some...

Electropolishing, also known as electrochemical polishing, anodic polishing, or electrolytic polishing (especially in the metallography field), is an electrochemical...

Anodic protection (AP) otherwise referred to as Anodic Control is a technique to control the corrosion of a metal surface by making it the anode of an...

John Glashan (born John McGlashan, 24 December 1927 – 15 June 1999) was a Scottish cartoonist, illustrator and playwright. He was the creator of the "Genius"...

hot cathodes allowed for lower acceleration anode voltages and higher electron beam currents, since the anode now only accelerated the electrons emitted...
