Pearson's Crystal Data: Features

Unlike the data information and software function lists (compare link on the left side), this article describes outstanding features, some of them garnished with screen shots. Click on a link in the feature list below, or start the features tour here.

  • Select from available values:
    Choose from lists of available values or define numerical ranges from histograms.
    Search for atomic environments.
  • Perpetual restrainting:
    Estimate results while you are still defining the search criteria.
  • All views at a glance:
    Answer set history, current selection criteria, entry report; entry data sheet, 3D structure picture, powder diffraction diagram, list of distances of current entry.
  • Dynamic plots:
    Plot unit cell parameters against temperature or pressure.
  • Figure plots:
    View pre-defined plots prepared by the editors of ”Pearson’s Crystal Data” and display e.g. a certain unit cell parameter as a function of temperature for a certain prototype.
  • Configure the entry report:
    Columns can be added to the table of all entries matching (answer set), or shifted or removed. Entry report configurations can be stored for later access.
  • Configure the entry data sheet:
    Choose the fields to be displayed for an entry each or the order of the fields.
  • Pictures of an entry each:
    Change, rotate etc. a 3D structure picture of the crystal structure, view atomic environments of selected atoms (polyhedra), simulate powder diffraction diagram.
  • Phases list:
    All entries belonging to the same phase, compiled in one row each.
  • Chemical system matrix:
    Graphical representation of all chemical systems of the current answer set as 2D matrix or 3D cube for binaries or ternaries, rsp.
  • Radii/volumes diagram:
    Diagram of atomic radii vs. unit cell diagonal or atomic volumes vs. unit cell volume for a selected prototype of an answer set.
  • Dossier of an entry:
    Compile all textual (data sheet, table of distances, etc.) as well as graphical information (3D structure picture, atomic enviroments, diffraction diagram) in one HTML document.

    (less detailed and without screen shots).
