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 ...

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

and when he got the urge to do some etching recently, he realized that he was fresh out of “Ferret Chloride and Bureaucratic Acid*.” Undeterred by his empty chemical cabinet, he poked around ...

The recovered materials can be upcycled to form silicon carbide wafers and other components for PV cells and microwave ...

Hundreds of regular patterns spontaneously emerge on a small germanium chip. A curiosity about tiny dots on a germanium wafer with metal films led to the discovery of intricate spiral patterns etched ...

That creates ions and more electrons. They also create free radicals. The radicals become the species that performs the chemical etching in a plasma etch system. These free radicals diffuse to the ...

The traditional method for etching glass uses a chemical-based cream that eats away at the glass to permanently create a stunning design. This DIY method is well suited for creating customized ...

Dry etching methods are all anisotropic processes; that is, they direct copper removal in a single direction and avoid the risk of undercutting. Wet methods, all of which rely on chemical ...

In the second step, both the heat-treated silicon (HT-Si) and untreated (UT-Si) fragments underwent chemical etching using basic 30 wt% potassium hydroxide (KOH) and nitric acidic (20 v% HNO3 ...

Telford precision manufacturer Advanced Chemical Etching has completed a £350,000 investment drive, as the company looks to grow its market in sectors such as aerospace and medical. ACE, which is ...
