TiB2 crystal structure
Dear Rietveld list subscribers, Does anyone know where I could find a publication with any information on the structure of TiB2? Cheers, Anthony Manerbino
Unknown amorphous phase.
Title: PDF Workshop Hello, I am working with samples that contain an unknown amorphous phase, which I would like to quantify. Does anyone know of any publications that might discuss some methods or techniques that may be used to determine the unknown amorphous phase. I would like to try and use a method that introduces an internal standard but I am open to all ideas. Thanks, Anthony Manerbino
RE: Unknown amorphous phase.
Thanks for the responses I have found a lot of very good information. No I can't obtain the amorphous phase pure, but I do know the chemical compostion and could probably make a good estimation on the density of the glass.

Can you obtain that "unknown amorphous phase" pure ? What do you mean by unknown, the chemical composition is also unknown, or do you just lack for a sructure model ?

GSAS question?
Can GSAS perform quantitative phase analysis? Anthony Manerbino B.Sc.

RE: new Windows version of GSAS
I am a new user of GSAS and have a few question about the installation. 1)This new version of GSAS in the windows folder does not contain pc-gsas after installation, is this a complete version to be run on a windows platform? 2)Why is this file almost 2 Mb smaller then the one in he MS-DOS folder? 3)When regisering a new file type you must enter a new extension for it, for expedt.exe the extension is .exp what are the extensions for powpref, genles, powplot so I can set up the "rigt click" method for these routines? Thanks, Anthony M. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Sent: Thursday, April 05, 2001 8:32 PM To: [EMAIL PROTECTED] Subject: new Windows GSAS Hi Everyone, I have placed a new Windows version of GSAS on the ftp server (ftp://ftp.lanl.gov/public/gsas) in the directory "windows". A small number of bugs in the original version were fixed: 1) A memory problem in GENLES 2) Some things in RAWPLOT for output files, etc. 3) Improvement in the algorithm for converting neutron TOF to d-spacing (solve a quadratic equation) 4) A few mistakes in the "readme" file. 5) A new overall parameter has been defined for "radiation damage" for x-ray powder data only. This is probably only useful for multidetector diffractometers at 3rd generation synchrotron sources (ESRF, APS, etc.). Its need became abundantly clear after a recent protein experiment at APS. Please give it a try and let me know especially if you find more bugs. It is a complete compile with a new compiler. This usually flushes out bugs. Bob Von Dreele
RE: new GSAS
Another question regarding GSAS. Which version of expgui runs best on the win2000 platform? Is EXPGUI a program used in place of the EXPEDT routine in GSAS? -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Sent: Monday, April 09, 2001 4:43 PM To: [EMAIL PROTECTED] Subject: new GSAS Hi Everyone, I have a new version of PC-GSAS.EXE that works in both Win95/98 and WinNT/2000 and have put the executable in ftp://ftp.lanl.gov/public/gsas/windows. There is also a new version for Linux in the directory /linux-beta. The main change is to make the exp & raw powder data files direct access with 82 character records each terminated with CR/LF. Thus, these files can be easily read and edited without any need for conversion. Their structure is identical to that for MS Windows so these files can be moved between operating systems without conversions as well. EXPEDT in Linux should convert your old Linux files to the new format. A conversion utility, CONVFILE, is also provided to do this job. Because of this format change Brian Toby's expgui may need some revision - Brian is working on this - but I wanted folks to try this version & let me know of bugs. This Linux version was compiled on RedHat 7.0 and linked to the downward compatible libraries so it should run in RedHat 6.2 or better (& equivalent). Bob Von Dreele
RE: new GSAS
When 'registering' GSAS experiment files with the windows operating system the file extension .exp is used when I register another routine such as powpref I attempt to use the same extension (.exp). The problem I'm encountering is registering the extension .exp multiple times, are you only able to link the extension to one subroutine at a time. Anthony M. -
RE: new GSAS
Is the program expgui used instead of the routine expedt for entering structural information and bring experimental patterns into GSAS?

I have mine setup with 6-7 different gsas programs available for an exp file. The "readme" gives directions for setting this up.
