Pushing X-Rays to the Edge to Draw the Nanoworld Into Focus
Mar. 11, 2013 — Photographers rely on precision lenses to generate well-focused and crystal-clear images. These high-quality optics -- readily available and produced in huge quantities -- are often taken for granted. But as scientists explore the details of materials spanning just billionths of a meter, engineering the nanoscale equivalent of a camera lens becomes notoriously difficult.
