He recently worked out a relatively inexpensive and easy way to etch metals using some chemistry skill and a little bit of electricity. After preparing a set of stencils and cleaning the metal ...

The nomenclature sets the stage for understanding the underlying reactions that make ferric chloride good at etching copper. In solution, ferric chloride rapidly dissociates into iron (III ...

These fluorination and ligand-exchange reactions lead to atomic layer controlled etching. This ALE approach is extendible to other materials besides metal oxides. Our current work has demonstrated the ...

"The thickness of the metal layer, the initial state of mechanical stress of the sample, and the composition of the etching solution all play a role in determining the type of pattern that ...
