Electron Microprobe Facility - Projects

Most UH microprobe users work in HIGP and GG. That means that we see a lot of meteorites, volcanic rocks and related experimentally produced materials. We also work with researchers from Civil and Mechanical Engineering and Material Sciences on applied projects, as well as local and mainland companies who take advantage of our capability to image and analyze at extremely high magnification.

Here are a few examples of our research:

1. Meteorites, Mars and Moon
