Scanning electron microscopy (SEM) studies 16,17,18,19 have reported conflicting results with reference to the marginal adaptation of MTA to root-canal walls. For example, Torabinejad et al. 16 and ...

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.” ...

Let’s get really, really small. That directive from leading semiconductor companies and their customers is forcing the whole semiconductor supply chain to come up with new ways to design and ...

It’s the little touches that make a project, and a nice nameplate can really tie a retro build together. Such badges are easy enough to make with a CNC machine, but if you don’t have access to machine ...

Metallographic etching is one of a number of processes that takes place during sample preparation for metallographic examination. The steps involved in preparing a sample include: Metallographic ...

The demand continues to grow for small but vital components. How chemical etching keeps tooling costs low and allows for rapid design changes. 1. Chemical etching can create complex, stress-free ...

A standard 13.56 MHz driven parallel plate reactive ion etcher (Trion Technology Minilock II), which allows internal anodization for use with chlorine was utilized for this experiment. Some features ...
