Apple’s iPhone Fold will not feature a crease, and that’s thanks to a key piece of technology that just leaked.

Sixty-five years after it first hit store shelves, the iconic, red-framed drawing toy continues to enchant kids, artists, and ...

Beautiful spiral patterns had been etched into the germanium surface by a chemical reaction. Wong's curiosity ...

The etching process involves exposing a small section of the sample surface to the etching solution. This creates pillars in the structure of 50 to 100nm in diameter. A 5mW 632.8nm HeNe laser creates ...

As a side benefit, the etching process makes metal surfaces water-repellant. Additionally, the treatment can be used to remove less chemically-stable particles from metal surfaces.

Comparing a physical vapor deposition and ion beam etch method to conventional trench etch followed by damascene deposition.

A metal bar is inserted in the other end of the bath, and both it and the work piece are connected to electrodes. The flow of electricity removes some metal from the exposed work surfaces ...

We’ve previously covered using electricity to etch metal in the workshop, as well as the gorgeous results that are possible with acid etched brass.

This proves that metal etched in such a way could be useful in the manufacturing of boats and ships, potentially giving them real “unsinkable” properties and allowing them to remain afloat ...

In addition, this process suffers from metal resputtering during the etching process. Polymer masks have been suggested in the literature; however, to process thicker PDMS layers with higher ...
