Cover illustration: X-ray fluorescence imaging of tooth sections performed at the APS reveals that mercury from dental amalgams migrates through human teeth to an area with an active bloodstream (see Harris, Vogt, Eastgate, Legnini, Hornberger, Cai, Lai and Lay, pages 123-128). The mercury map (bottom left) also indicates that mercury accumulates in calculus on the right-hand side of the tooth. Hg L3-edge MicroXANES (bottom right) indicates that mercury is chemically altered either during or after the transport process.

The distributions of the metals Hg, Zn and Cu in sections of amalgam-filled human teeth have been mapped using an X-ray fluorescence microprobe. The results indicate significant migration of mercury from the restoration through the tooth towards an area with an active bloodstream.

It is shown that the diffraction in highly regular prism arrays of the clessidra (hourglass) type in a completely spatially coherent incident X-ray beam is of the Fresnel (near-field) type, which will theoretically allow these lenses to operate with the diffraction-limited spatial resolution expected for their large aperture.

An experimental set-up is presented which combines simultaneous optical and X-ray scattering measurements with a short-term shearing apparatus for studying polymer flow-induced crystallization. Optical measurements provide sufficient sensitivity to detect the formation of oriented precursors during flow, while their impact on morphology development after flow cessation can be quantified with X-ray scattering.
