Dear Colleagues, In the last version of DDM_GUI the default value of the asymmetry parameter FCJ was erroneously set to 1 instead of 0, which might cause...
Dear All: I didn't find anyone giving a datum for (333) reflection of MgAl2O4 in the PDF database. What's the reason? I don't find any reason for it to be a...
Dear Colleagues, we cordially invite you to the SMARTER 3 conference, held in the University of Versailles Saint Quentin en Yvelines (France), September 10-13,...
Hi,everyone, you know, 104 reflection is usually preferred in carbonates,such as dolomite and calcite.As a result, observed 104 often becomes stronger than...
Hi,everyone,I'm here again! I'm confused on some space group symbol in cif files. For example, the symmetry space group name H-M is "F d -3 m S" in the...
Hi,everyone, I wonder whether someone has refined these data of Round Robin QPA of IUCrCPD. Sample 4 presented a microabsorption problem. I try to refine this...
Hi, everyone, In Gsas' manual, I find that the relation between Biso and Uiso is Biso=8pi2*Uiso. In my opinion, they mean the same thing. I wonder whether it's...
Dear friends, I tried to download and install the recent database for the "search match" software Match! by crystal impact. Following file was downloaded: ...
Hello all I am new in Rietveld refinement, so I tried to refine the structure of BaTiO3 from X ray data by using Fullprof software, but unfortunately I...
Hi, dear all, My question is how to get the amorphous phase weight% by Fullprof or other softs if no standard sample isn't added. For example, how do you get...
Any experience and/or tips for installing crysfire on modern (32 or 64 bit, Windows 7) computers? I fetched and unzipped crys2004.zip from CCP14, and when I...
Dear all, please I want to ask about the micro-strain and lattice distortion calculated from XRD data. What does this reflect exactly? is there any relation...
Too late for that one. Solved from synchrotron powder data. Published in August 2011. Corresponds to compound 2 in: http://www.ncbi.nlm.nih.gov/pubmed/21739550...
Dear SDPD members, I am sorry if this mail is not related to SDPD, this is regarding the installation of EXPGUI-GSAS on windows 7 PCs. Can somebody help me out...
Hi, Only 16 books about crystallography in the new Book Citation Index in the Web of Science : http://wokinfo.com/cgi-bin/bkci/search.cgi Only one about Powder...
Hi, Some more efforts from you and SDPD would have a place larger than 0.5 % per year in the total crystal structure production which will be celebrated during...
Dear all, Sorry for so simple questions, as I am a beginner in this field. Can anyone tell me in detail how to do the difference fourier method to find the...
Hi folks, I'd like to ask for your help what the origin shift is for the same space group but with different setting. i'm currently studying the fergusonite...
Dear Colleagues! The DDM program is updated to version 1.9 at: http://sites.google.com/site/ddmsuite/ and http://l-solovyov.narod.ru/ddm.html The main changes:...
