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 ...

The problem? The laser won’t cut into the hard metal of the scissors. His solution? Smear the scissors with mustard. No kidding. We’ve heard of this before, and apparently, you can use vinegar ...

A chemical etching method for widening the pores of metal-organic frameworks (MOFs) could improve various applications of MOFs, including in fuel cells and as catalysts. Researchers at Nagoya ...
