For a lot of reasons, home etching of PCBs is somewhat of a dying art. The main reason is the rise of quick-turn PCB fabrication services, of course; when you can send your Gerbers off and receive ...

A lab mistake led to self-forming spiral patterns on metal surfaces, revealing chemical-mechanical interactions.

UCLA doctoral student Yilin Wong left a sample out by mistake. It was a small chip made of germanium, topped with thin layers ...

Although the typical cliché for a mad scientist usually involves Bunsen burners, beakers, and retorts, most of us (with some exceptions, of course) aren’t really chemists. However, there are ...
