UCLA doctoral student Yilin Wong noticed that some tiny dots had appeared on one of her samples, which had been accidentally ...

Curiosity about a mistake that left tiny dots on a germanium wafer with evaporated metal films led to the discovery of beautiful spiral patterns etched on the surface of the semiconductor by a ...

PCB etching methods generally fall into one of ... First, a bit about nomenclature. Compounds with metal cations (positively charged species) have traditionally used different suffixes to denote ...

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 ...

[5-Speed Power Engraver] The engraving tools can adjust 5 different speed at 6000/min strokes to meet your different needs. The metal etching tool is a perfect gift for hand maker, Christmas ...

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 ...
