Chemical etching (also called photochemical etching, photo etching, or chemical milling) is a precision manufacturing method ...

With photolithography not able to produce circuit lines much thinner than 100nm, a major focus of research into nanotechnology is in developing means to construct circuits that break the 100nm barrier ...

As any good metallurgist will tell you, you can't just take any two types of metal and weld them together. You may instead be able to just join them together with glue, however, thanks to research ...

If you were building a recreation of the James Watt micrometer, where would you start? If you’re [rasp], the answer would be: “Spend a year trying to find the best way to make etched brass discs.” ...

Etching is a method employed during the fabrication of semiconductors to chemically remove layers from the surface of the wafer substrate. Etching is a crucial process, and each wafer is subject to ...

Copper’s resistivity depends on its crystal structure, void volume, grain boundaries and material interface mismatch, which becomes more significant at smaller scales. The formation of copper (Cu) ...

Extracting hydrogen from water through electrolysis offers a promising route for increasing the production of hydrogen, a clean and environmentally friendly fuel. But one major challenge of water ...
