Only relatively pristine material has the goods Landman is after, so his team USES a scanning electron microscope (below), which utilizes a beam of electrons to image surfaces, to find the best nacre.

Results EBCT had the advantage of high speed in scanning and high resolving power of time without mechanical abrasion due to the using of electron beam.

It is very effective to use the scanning electron beam (EB) heating to braze the stainless steel structural part with capillary-to-plate joints.
