Cover illustration: Phase-contrast synchrotron radiation high-resolution radiography images of the fourth digit of the normal frontal limb of a rodent (see Choi, Kim, Choe, Kim, Choi, Jheon and Kim, pages 393-399). Left: overlaying X-ray image of the whole length of the digit clearly shows joints, the alignment of phalanges and the status of the surrounding soft tissue. On the right, a single image allows identification of articular cartilage (arrow), chondrocytes lacunae (L), subchondral bone and bone marrow space (M) of the distal interphalangeal joint (DIP) in detail.

The current work shows the calculation and study of an X-ray one-dimensionally focusing system composed of Bragg double-asymmetric-reflecting two-crystal plane parallel plates and a double-concave cylindrical parabolic lens placed in the gap between the plates. The focusing distance is calculated, intensity distribution curves are given in the focusing plane and on the focusing line, and the intensity at the focus point and the longitudinal and transverse sizes of the focus are defined.

The growth kinetics of NiO nanoparticles have been studied by in situ X-ray diffraction using two detection systems: conventional and imaging plate. The evolution of particles size and the diffusion coefficient obtained from X-ray powder diffraction patterns are discussed in terms of the thermal conditions for the two types of detection.

In order to reproduce principal B K-edge XANES features in boron-containing minerals, it is sufficient to use a non-self-consistent potential with a relaxed and screened core hole. The core hole affects the spectrum significantly, especially in the pre-edge region.
