SOFTWARE
  • "KRISTALSHAPER: this program draws crystal shapes for normal crystals and icosahedral quasicrystals. It is possible to export webpages in the HTML language, which use the provided Applet, so that crystal shapes can be viewed within a Java-enabled webbrowser, such as Microsoft Internet Explorer. KrystalShaper itself has more rendering options than the applet. It might thus be used as an interface for the creation of interactive webpages."
  • "SHAPE is a program to calculate and display the morphology and symmetry of single crystals, twins and epitaxial and other intergrowths. Some of the basic mathematical aspects of the program were described in a paper in The American Mineralogist (1980, V.65, p.465). To draw an individual crystal, it is necessary to enter only the crystal class, the unit cell parameters, and the indices and central distance for one face of each form. The crystal drawing can be rotated, translated and rescaled, and crystal axes can be added at will. The central distances, which determine the prominence (area) of each form, may be derived from the unit cell and space group, using the Donnay-Harker morphological "law". The crystal can be displayed in an orthographic projection rotated in a standard way, or in a "straight-on" orthographic projection, and the view of the crystal can be combined with a stereonet showing the poles to the faces and the crystal axes."
  • "STEREONET is a user friendly tool to display, change and analyze orientational data. It displays data in different views: as text, in equal area / equal angle upper / lower hemisphere projection, etc. using diffent symbols, colors etc and also shows great circles, small circles and displacement vectors. Additionally, StereoNet rotates the data as well as computes some simple statistical parameter. StereoNet also contours data densities and computes paleostress directions from fault-slip data. Included is a little help file, and an example dataset."
  • WINWULFF: "is a program for plotting stereographic projections of (hkl) and [uvw] vectors onto a Wulff-net."
  • POWDER-CELL "The aim of this software is at first an intuitive structure modification by manipulation step by step and an quasi-simultaneous comparison between experimental data and calculated powder diffraction pattern. At second the program contains refinement procedures to adapt experimental and theoretical data automatically." 
  • X POWDER es un programa que permite realizar análisis cualitativos, cuantitativos y microestructurales a pertir de patrones de rayos X. El software trabaja con dos bases de datos ICDD-PDF2 y  difdata.txt. Realiza cálculos cuantitativos mediante métodos de cuadrados mínimos lineales y no lineales sobre el diagrama completo en materiales amorfos o cristalinos, a partir de difractogramas-estandar experimentales. (RECOMENDADO)
  • "CRYSTALSLEUTH is capable of analyzing and manipulating both Raman and powder diffraction data sets. Utilizing robust routines, we remove background noise and cosmic ray events from patterns with a convenient interface that also permits comparison of multiple spectra. CrystalSleuth can automatically locate and store peak positions, refine the unit cell from powder diffraction patterns, as well as search/match by referencing peak positions against the online database. Additionally it offers a user definable environment to maximize individual productivity."
  • "POWDLL is a .NET dynamic link library used for the interconversion procedure between variable formats of Powder X-Ray files. The DLL is capable of handling the most common file formats (binary and ASCII). The library  can be used as a reusable component with any .NET language or as a standalone utility by running the setup."
  • MICROTERMOMETRÍA I: desde la página del Dr. Ronald J. Bakker se pueden descargar pequeños paquetes de software que permiten realizar los cálculos microtermométricos de distintos sistemas.
  • MICROTERMOMETRIA II: descarga del programa FLINCOR diseñado por el Dr. Philip E. Brown para cálculos microtermométricos.
