(PhysOrg.com) -- What if you could turn the whole haystack into needles? Instead of hunting for one item, you’d have 10 billion of the desired items laid out neatly in front of you. That’s what researchers at the Pacific Northwest National Laboratory did for scientists analyzing nanoparticles. Using the ion soft-landing technique developed at PNNL, the scientists prepared a homogeneous, contaminant-free sample of gold clusters, tiny particles made up of 11 gold atoms each. The team then analyzed the samples in the new aberration-corrected transmission electron microscope or TEM at EMSL.
