Such badges are easy enough to make with a CNC machine, but if you don’t have access to machine tools you can put chemistry to work for you with these acid-etched brass nameplates. The etching ...

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 ...

Atomic layer etching (ALE) is the reverse of atomic layer deposition (ALD). ALE can be achieved using sequential, self-limiting thermal reactions. We have recently demonstrated Al 2 O 3 ALE [1-3] and ...
