What is Pcpdfwin?




Pcpdfwin is a software that allows users to access and search the PDF-2 database of powder diffraction patterns. The PDF-2 database is a collection of over 300,000 entries of experimental and calculated powder diffraction data for various materials, such as minerals, metals, alloys, ceramics, polymers, and organic compounds. The PDF-2 database is maintained by the International Centre for Diffraction Data (ICDD), a non-profit organization that promotes the use of powder diffraction for material characterization.


Pcpdfwin enables users to search the PDF-2 database by various criteria, such as chemical name, formula, crystal system, space group, cell parameters, peak positions, intensities, and references. Users can also perform pattern matching between their own XRD spectra and the PDF-2 database entries, and identify the most likely phases present in their samples. Pcpdfwin also provides tools for data manipulation, such as scaling, smoothing, background subtraction, peak fitting, and indexing.


Pcpdfwin is a useful software for anyone who performs XRD analysis on different materials. It can help users to quickly and accurately identify the phases in their samples, compare their results with the literature data, and generate reports and publications. Pcpdfwin is especially helpful for users who work with complex or unknown materials, such as new alloys, nanomaterials, or polymorphs.


What is XRD Analysis?




XRD analysis is a technique that uses X-rays to identify the crystal structure and composition of materials. X-rays are electromagnetic radiation with wavelengths in the range of 0.01 to 10 nanometers. When X-rays interact with matter, they can be diffracted or scattered by the atoms in the material. The diffraction pattern depends on the arrangement and spacing of the atoms in the material, which reflects its crystal structure.


XRD analysis involves exposing a sample to a beam of X-rays and measuring the intensity and angle of the diffracted rays. The resulting spectrum is called an X-ray diffraction pattern or an XRD spectrum. By comparing the XRD spectrum of the sample with known diffraction patterns of different materials, one can determine the identity and quantity of the phases present in the sample.


XRD analysis is a powerful technique for characterizing various materials, such as metals, ceramics, polymers, composites, minerals, rocks, soils, drugs, and biological molecules. It can provide information about the crystal structure, lattice parameters, unit cell volume, crystallite size, strain, texture, preferred orientation, phase transitions, polymorphism, crystal defects, and chemical composition of materials. XRD analysis can also be used to study the physical properties of materials, such as thermal expansion, elastic modulus, magnetic properties, and electrical conductivity of materials. XRD analysis is widely used in various fields, such as material science, engineering, geology, chemistry, physics, biology, pharmacy, and archaeology.

How to Install Pcpdfwin on Windows 7?




Pcpdfwin is a software that was originally designed for Windows XP and earlier versions of Windows. Therefore, it may not be compatible with Windows 7 and newer versions of Windows. However, there are some possible solutions to install Pcpdfwin on Windows 7, such as using VirtualPC, compatibility mode, or alternative software.


VirtualPC is a software that allows users to create and run virtual machines on their computers. A virtual machine is a simulated environment that mimics the hardware and software of another computer. By using VirtualPC, users can install and run Pcpdfwin on a virtual machine that runs Windows XP or another compatible operating system. To use VirtualPC, users need to download and install VirtualPC from Microsoft's website, create a virtual machine with Windows XP or another compatible operating system, and then install Pcpdfwin on the virtual machine. Users can then access and use Pcpdfwin from the virtual machine as if it were a real computer.


Compatibility mode is a feature that allows users to run programs that were designed for older versions of Windows on newer versions of Windows. By using compatibility mode, users can try to run Pcpdfwin on Windows 7 as if it were running on Windows XP or another compatible operating system. To use compatibility mode, users need to right-click on the Pcpdfwin executable file or shortcut, select Properties, click on the Compatibility tab, check the box that says "Run this program in compatibility mode for:", and choose Windows XP or another compatible operating system from the drop-down menu. Users can then click on Apply and OK, and then run Pcpdfwin normally.


Alternative software is another option for users who want to use Pcpdfwin on Windows 7. There are some other software that can perform similar functions as Pcpdfwin, such as Match!, Xpert Highscore, XPowder, Jade, QualX, or Crystallography Open Database. These software may have different features, databases, compatibility, prices, and user reviews than Pcpdfwin. Users can compare these software and choose the one that suits their needs and preferences best. We will discuss more about these alternatives later in this article.


How to Search and Match XRD Spectra with Pcpdfwin?




Pcpdfwin is a software that allows users to search and match XRD spectra with the PDF-2 database of powder diffraction patterns. This can help users to identify the phases present in their samples and compare their results with the literature data. To search and match XRD spectra with Pcpdfwin, users need to follow these steps:


  • Open Pcpdfwin and click on File > Open Data File. Browse and select the XRD data file that contains the spectrum of the sample. The XRD data file should be in ASCII format with two columns: one for the 2-theta angle and one for the intensity. The file name should have a .xrd extension. Click on Open.



  • The XRD spectrum of the sample will be displayed in the main window of Pcpdfwin. Users can adjust the scale, zoom, offset, or color of the spectrum by using the buttons on the toolbar or the menu options.



  • To search the PDF-2 database for matching entries, click on Search > Search PDF-2 Database. A dialog box will appear where users can specify the search criteria, such as chemical name, formula, crystal system, space group, cell parameters, peak positions, intensities, and references. Users can also choose the search mode, such as exact match, partial match, or range match. Users can also limit the number of results to be displayed. Click on OK.



  • The search results will be displayed in a table in a new window. The table will show the PDF-2 entry number, chemical name, formula, crystal system, space group, cell parameters, and quality mark for each matching entry. Users can sort the table by any column by clicking on the column header. Users can also view the diffraction pattern of any entry by double-clicking on the entry number.



  • To match the XRD spectrum of the sample with the diffraction pattern of a PDF-2 entry, users need to select the entry number from the table and click on Match > Match Selected Entry. A dialog box will appear where users can adjust the matching parameters, such as scaling factor, background subtraction, peak fitting, and peak width. Users can also choose to display the difference curve or the residual curve between the sample spectrum and the PDF-2 pattern. Click on OK.



  • The matching result will be displayed in a new window. The window will show the XRD spectrum of the sample in red, the diffraction pattern of the PDF-2 entry in blue, and the difference curve or the residual curve in green. Users can also see the matching statistics, such as the correlation coefficient, the figure of merit, and the R-factor. Users can compare the peak positions and intensities of the sample spectrum and the PDF-2 pattern to evaluate the quality of the match.



  • Users can repeat steps 4 to 6 for different PDF-2 entries until they find the best match for their sample spectrum. Users can also perform multiple matching by selecting more than one entry from the table and clicking on Match > Match Multiple Entries. This will display all the selected entries in different colors on the same window. Users can then compare and combine different entries to identify all the phases present in their sample.
