XPowder 1.0
This program is the result of forming in a project only and professional,
all the experiences that throughout many years have had in the field of the
X-Rays diffraction by the powder method. Actually there is no nothing new,
since all what at this time are grouping, it makes it our program PLV
(MS-DOS) in some of its multiple options and versions. The problem that has
PLV is its huge difficulty of use to the not to have implemented the
advantages that Windows offers concerning graphic, popups menus and in line
help.Furthermore if does not exist version in English of the same (only in
spanish). The XPowder 1.0 project born by the presure and insistence of
many users of PLV and of other similar programs and because does not exists
in the market any product that offer in a way integrated what a researcher
of this field specifies to cover the, at least, eighty percent of their
needs. We wish that the bottom line will be a confortable and inexpensive
product (if not free of charge) for all. The complete program will ocuppy
approximately 20 Mbytes of disk report and will be installed from a CDROM
from Windows 95/NT.
The characteristics and facilities of XPowder 1.0 are:
=B7 Confortable graphs acquisition by serial port. Possibility from importin=
g
and exporting data to other fromats.
=B7 Phases identification. The program understand the PDF1-2 format and the
identification are made very confortable. It can use the ingenious method
of PLV for the authomatic identification in mixtures or well the classic
methods of analysis of peak coincidences (in real time). To accede at this
option You will have to posses the corresponding database (CDROM
distributed by ICDD) with the corresponding license.
=B7 Analysis semi and quiantitative by a way simple definable standards.
Preferential orientation treatment.
=B7 Signals treatement (filters, backgrounds, Ka=BD, 2q displacement, sums,
substractions, etc..)
=B7 Profiles analysis (with applications to crystalinities, sizes and
residuals tensions)
=B7 Unit cell refinement for complete counterfoil of least square, with
bounds. Use the same procedure that PLV.
=B7 Reflections indexations graph in authomatic form. Very useful in the
first steps of ab initio structural determination.
=B7 Instructuions generation optimized for other programs of general use suc=
h
as TREOR, GSAS or DBWS.
The project is very advanced, and operate already several modules. Have to
be anticipated the following periods:
May - June 1998 Beta Version. It will be distributed in CDROM to price
of cost (already 20 $) or gratuitously, in function of the subsidies that
we procure.
June 1998 - May 2000 Evaluation and improvement
January 2000 Final product.
