He recently worked out a relatively inexpensive and easy way to etch metals using some chemistry ... After preparing a set of stencils and cleaning the metal work surface, [Peter] sets his work ...

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 ...

Next, the researchers placed a drop of mild etching solution onto ... a chemical reaction catalyzed by the metal film etched remarkable patterns on the germanium surface. Investigation of the ...

Many hobbyists and hackerspaces have the $500 Chinese 40W lasercutters which most of us know are about as successful at etching metals ... onto the stainless surface (both worked), the mixture ...

Using lasers to etch and alter the surface of the metal, Raymond and his colleagues were able to create micro- or nanoscale textures that make it difficult for microbial cells to attach to the ...

During the surface chemistry using HF and Sn(acac ... and ligand-exchange reactions lead to atomic layer controlled etching. This ALE approach is extendible to other materials besides metal oxides.

Surface engineering is transforming battery technology. From nano-patterned electrodes to protective coatings and dendrite ...

Such an in situ electrochemical etching method can be used to expose various well-defined metal surfaces in solution. The atomic structures of semiconductor surfaces of Si and GaAs were successfully ...
