Electroetching is a metal etching process [1] that involves the use of a solution of an electrolyte, an anode, and a cathode. The metal piece to be etched is connected to the positive pole of a source of direct electric current. A piece of the same metal is connected to the negative pole of the direct current source and is called the cathode. [2]
Etching tanks used to perform Piranha, hydrofluoric acid or RCA clean on 4-inch wafer batches at LAAS technological facility in Toulouse, France. Etching is used in microfabrication to chemically remove layers from the surface of a wafer during manufacturing. Etching is a critically important process module in fabrication, and every wafer ...
Electropolishing, also known as electrochemical polishing, anodic polishing, or electrolytic polishing (especially in the metallography field), is an electrochemical process that removes material from a metallic workpiece, reducing the surface roughness by levelling micro-peaks and valleys, improving the surface finish.
Stereotyping had been invented around 1725, and was already well-established when electrotyping was invented in 1838. Both methods yielded plates that could be preserved in case of future needs, for example in the printing of novels and other books of unpredictable popularity. The movable type used to compose the original forme could then be re ...

Etching by Daniel Hopfer, who is believed to have been the first to apply the technique to printmaking. Etching is traditionally the process of using strong acid or mordant to cut into the unprotected parts of a metal surface to create a design in intaglio (incised) in the metal. [1] In modern, other chemicals may be used on other types of ...
Adhesive dentistry is a branch of dentistry which deals with adhesion or bonding to the natural substance of teeth, enamel and dentin.It studies the nature and strength of adhesion to dental hard tissues, properties of adhesive materials, causes and mechanisms of failure of the bonds, clinical techniques for bonding and newer applications for bonding such as bonding to the soft tissue.

Electron-beam processing or electron irradiation (EBI) is a process that involves using electrons, usually of high energy, to treat an object for a variety of purposes.This may take place under elevated temperatures and nitrogen atmosphere.
