The silver metal (Ag°) image formation in these imaging elements is based on the heat-induced reduction of the silver behenate. The completed reduction process has historically been studied by conventional X-ray diffraction techniques. To enhance the understanding of the kinetics of silver metal formation, equipment and methods were developed allowing for in situ hightemperature monitoring of the AgBehenate → Ag° reduction process. To perform the necessary measurements a high-temperature sample stage and position sensitive detector were mounted on the X3B1 beam line powder diffractometer at the National Synchrotron Light Source, Brookhaven National Laboratories. The fraction of AgBehenate reduced and Ag° developed was obtained from the synchrotron data and it was determined that the reaction rates for both processes followed a second order transformation. The activation energy was derived from...

Brigatinib Form A crystallizes in space group P-1 (#2) with a = 9.59616(20), b = 10.9351(3), c = 14.9913(6) Å, α = 76.1210(13), β = 79.9082(11), γ = 74.0802(6)°, V = 1458.497(15) Å3, and Z = 2. Structure solution was complicated by the lowest cost factor solution having an unreasonable conformation of the dimethylphosphoryl group. The second-best structure yielded a better refinement. The crystal structure is characterized by alternating layers of aliphatic and aromatic portions of the molecules along the b-axis. Strong N–H⋯N hydrogen bonds link the molecules into pairs, with a graph set R2,2(8). There is a strong intramolecular N–H⋯O hydrogen bond to the phosphoryl group, which determines the orientation of this group. The powder pattern has been submitted to ICDD® for inclusion in the Powder Diffraction Fil...

It is also a year to celebrate the 75th anniversary of the International Centre for Diffraction Data™, ICDD ® , the 30th anniversary of Powder Diffraction journal, and the 65th anniversary of the Denver X-ray Conference ®. In writing this editorial it was an opportunity to look at the history of the conference and gain an appreciation for how it has evolved over 65 years.

As part of EPDIC 14, the International Centre for Diffraction Data (ICDD) sponsored the publication of the conference proceedings. Through Cambridge University Press, the EPDIC 14 proceedings with 21 papers (see Table I) are being published online (http://jour nals.cambridge.org/action/displayJournal?jid=PDJ). EPDIC 14 attendees receive free access to the proceedings for 2 years and subscribers to Powder Diffraction also have access. Anyone without a PDJ subscription or did not attend EPDIC 14 can purchase any of the articles for a fee. I would like to thank the EPDIC 14 Proceedings Editors Jens-Erik Jorgensen, Paolo Scardi, and Michela Brunelli for their efforts in getting all of the papers together, reviewed, and approved for publication. A special thanks to Nicole Ernst-Boris, Powder Diffraction Managing Editor, for her diligence in coordinating the submission of manuscripts to Cambridge University Press (Photo 1).

After reviewing 32 XRD (X-ray Diffraction), XRF (X-ray Fluorescence), and related fields AXA papers, five were selected for publication in Powder Diffraction. The five selected papers highlight interesting developments in materials analysis. Together with the regular published papers in this June issue of Powder Diffraction readers are provided with the opportunity to learn about current topics in a variety of materials characterization applications.

Our method consists of evaporation of CO2-enriched water microdroplets containing dissolved organic salts and yields a variety of porous scaffolds with micron-sized pores. In addition, the films are characterized by a hierarchy of structural features, such as nanowires, nanorods, 2-dimensional crystals, or nanopores. This scalable, environment-friendly method is applicable to a wide variety of ceramic materials and can lead to materials with an improved performance in catalysis, sensors, solar cells, fuel cells, and tissue engineering.

Although the most published articles discuss the use of X-ray powder diffraction, the journal has expanded over the years to include neutron diffraction, electron diffraction, X-ray fluorescence, and additional analytical techniques all used for phase identification and material micro (and nano) structure characterization. The content of Powder Diffraction continues to increase as current subscribers to PDJ also receive the latest volume of the Denver X-ray Conference Proceedings Advances in X-ray Analysis, as well as access to online special supplement publications of recent International Conferences. For 2014 the Proceedings of the Australian X-ray Analytical Association (AXAA) 2014 Meeting will be published and in 2015 the Proceedings of the recently held European Powder Diffraction Conference, EPDIC 14, will be published. For the Powder Diffraction readers, the vast number and variety of publications provide a unique opportunity to stay current in the practice and theory of diffraction and scattering techniques.

These topics and the timing of publishing in June are intended to compliment a workshop at the Denver X-ray Conference held in August of each year. With the success of the special topics section, Ting Huang, Powder Diffraction Editor-in-Chief, approached me with another opportunity to help put together a special topics section for 2004. This time, the focus would be on microanalysis. One workshop covering microdiffraction and microfluorescence and another workshop covering microbeam X-ray stress analysis provided the focus for this year's special topics section. Type the word nanotechnology into a popular internet search engine and you will get over 1,400,000 hits....microelectronics 847,000ϩ hits. Follow with a search on microanalysis and the response is over 3,200,000 hits. Little is big! Characterization of micro and nanomaterials is a critical component for the success of technologies relying on the properties of a few atoms. In this issue of Powder Diffraction you will find papers covering micro X-ray diffraction, micro X-ray fluorescence, microbeam X-ray stress analysis, and electron backscattered diffraction, all important in the understanding of micro and nanomaterials science. I'd like to thank the authors who contributed the papers that comprise the special topics section. The schedule was tight for getting the papers written, reviewed, revised, and submitted on time to the publisher. I would also like to thank Ting Huang for giving me the chance to again work on a special topics publication, and Cathyann Colaiezzi, Managing Editor Powder Diffraction, for making sure everything was in place for this June publication. The result is a collection of excellent reference articles that will serve as an education tool for the analysis community.
