Cover illustration: MicroGISAXS (ID13, ESRF) measurement of a protein thin Langmuir-Blodgett film (see Pechkova, Tripathi and Nicolini, pages 330-335). A characteristic feature of a GISAXS pattern is the Yoneda peak, shown here in blue.

The dramatic increase in long-range order in Langmuir–Blodgett multilayered enzyme films after heating and cooling is made apparent by grazing-incidence small-angle X-ray scattering using a microbeam.

The quality of small-angle X-ray diffraction patterns of quick-frozen hydrated biological specimens has been correlated with the state of the ice as inferred from simultaneously recorded wide-angle scattering. The relation between the diffraction quality and the distance from the surface, and the effect of cryoprotectants is discussed.

A high-precision diffractometer with a synchrotron radiation microfocusing technique has been developed to investigate the crystal structure of a submicrometre-scale single grain of powder sample. The structure of a BaTiO3 single powder grain, of dimensions ∼600 × 600 × 300 nm, was determined.

An X-ray magnetic circular dichroism study performed at the rare-earth L2,3-edges in the RxR1−x′Al2 compounds is presented, showing that both R and R′ atoms contribute to the XMCD recorded at the L-edges of the selected rare-earth, either R or R′.

Arsenic applied in the preservation of taxidermy specimens was shown with imaging X-ray fluorescence to penetrate the hair. This complicates efforts to identify endogenous arsenic in poisoning cases, but reduces potential exposure when handling specimens.

Single-walled carbon nanotubes (SWCNTs) treated by nitric acid are investigated, giving evidence of the oxidation on both the carbonaceous fragments and the side walls of SWCNTs. It is also shown that washing with sodium hydroxide removes carboxylated carbonaceous fragments and a further acid treatment will directly modify the tube walls of SWCNTs.
