Scientists lead by EPFL, the University of Copenhagen, and Shanghai University have developed a copper catalyst that can ...

We need a way to dissolve a little bit of copper from the board and get it to react with some chloride ions. This is commonly done with a mixture of hydrochloric acid and hydrogen peroxide.

Italian and Japanese researchers have developed a novel method to free copper wire from its PVC coating, by treating electric cables with microwaves. The technique could go a long way towards helping ...

A cotton swab is dipped into concentrated hydrochloric acid (producing hydrogen chloride gas) while a second on is dipped into concentrated aqueous ammonia (producing ammonia gas). Both cotton swabs ...

We can use a gas syringe to measure the reaction of metals with dilute acid. When zinc reacts with hydrochloric acid it produces zinc chloride and hydrogen gas. We can measure the rate of the ...

It’s not like etching with hydrochloric acid and peroxide is anything new ... There are a bunch of ways to etch copper off boards, including the messy old standby etchant ferric chloride ...
