Every node (the little triangular etch) on the stem is a potential new bloom.
To draw lines, the etch a Sketch's stylus scrapes aluminum powder from the underside of a glass screen.
Last, a technique known as anisotropic ion beam milling (IBM) is used to etch through the mask to make an array of holes, creating the nanoporous metal.
Heat damage generally is removed by carefully machining the base metal. Afterward, another temper etch inspection is done to ensure that the machining did not create more heat damage.
The second is to use a good etch resist.
More often , all of the materials etchant have a finite etch rate.
While most photographers are loathe to let a stray fingerprint near their negatives, Ben Ali Ong chooses to scratch, etch and generally distort his on purpose.
Bite: Stage in the process of etching a metal block or plate with acid. Each application of the acid increases the depth of the etch and is called a "bite".
Based on ash chamber of metal etch this paper describes the full process of dry clean development and evaluation.
Researchers at HP Labs recently managed to etch a pattern into a flat piece of silicon so that it could focus light "like a spoon", says Raymond Beausoleil of HP Labs.
The inability to etch chips with lasers in the shorter wavelengths has limited how precisely they can design circuits on silicon.
They've used lasers to etch the Yangcheng name on crab shells.
He also believes it should be possible to extend the principle beyond superconductors, to use X-rays to etch out electronic circuits more generally.
This unit group also includes workers who etch or chemically mill metal pieces.
