Accuracy in Powder Diffraction IV

We are pleased to announce the location and dates for our next "Accuracy in Powder Diffraction" meeting. This meeting, designated APD-IV, is the fourth in the series which are held approximately every ten years. They constitute a review of the state of the art in powder diffraction techniques, instrumentation and data analysis methods. The meeting will host a program of invited presentations plus a contributed poster session. APD-IV will cover the broad range of developments in powder diffraction metrology and methodology in the time since APD-III. In addition, we will host an exhibition area where leading instrument manufacturers and providers will be available to discuss recent commercial developments in the diffraction context.
