“Vivertana” is an organization focused on the distribution, installation and training on the International Center for Diffraction Data “(ICDD) databases and software” to the Indian universities, research institutions and industry. The name Vivertana is based on the definition given in Shabdkosh for diffraction. विवर्तन पैटर्न stands for diffraction pattern, विवर्तन अध्ययन for diffraction studies and विवर्तन डेटा for diffraction data.
Matter exists in three phases, Gases, Liquids and Solids depending on the temperature and pressure of the surroundings. All solid materials have a characteristic diffraction pattern particularly when they are in crystalline form which serves as a fingerprint for unique identification .....
X-ray Diffraction (XRD) is a technique used for determining the atomic and molecular structure of a crystalline material, in which the crystalline structure causes a beam of incident X-rays to diffract into many specific directions as governed by the well known Bragg’s law. Powder XRD is used extensively for the identification of phases by measuring the diffraction angles and intensities of these beams, and comparing the resulting diffraction pattern to a reference database. The reference data is compiled in the ICDD database and consists of nearly 1,186,000 entries with well defined classification based on the properties of the given crystalline substance. The diffracted beams appear as peaks and any deviation observed can be identified and quantified using the software available along with the database. It is helpful to analyze the product prepared by the user, check the purity and repeatability. For example, in the manufacture of a pharmaceutical compound, if in case there are deviations in such quantification of diffraction data, the product becomes unacceptable for consumption. Hence, evaluation of a product prepared in the laboratory via X-ray diffraction studies becomes an essential and vital component in manufacturing and design of desired products. Diffraction data thus becomes an unequivocal requirement to prove the final product purity, reproducibility and stability on storage. With the sudden surge in the growth of industry in India, the research and development wing of each such establishment needs the database, and it is the intent of Vivertana to license, train and implement.
The International Centre for Diffraction Data (ICDD) located at 12, Campus Boulevard, Newtown Square, PA 19073-3273 United States maintains a database of powder diffraction patterns, the Powder Diffraction File (PDF), including the d-spacings (related to angle of diffraction) and relative intensities of observable diffraction peaks. Patterns may be experimentally determined, or computed based on crystal structure and Bragg's law. It is most often used to identify substances based on X-ray diffraction data, and is designed for use with a diffractometer. The PDF contains more than a million unique material data sets. The ICDD produces materials databases, characterization tools, and educational materials, as well as organizing and supporting global workshops, clinics and conferences. Products and services of the ICDD include the paid subscription based Powder Diffraction File databases (PDF-2, PDF-4/Minerals, PDF-4/Axiom, PDF-5+ and ICDD Server Edition), educational workshops, clinics, and symposia. ICDD also provides the JADE software (A product of MDI) to collect, analyze, and simulate XRD data and solve issues in an array of materials science projects.
California-based Materials Data has created XRD applications for over thirty years, enjoying a well-earned reputation for being pioneers of implementing new scientific ideas and novel approaches into our XRD Applications. We were the first to include Whole Pattern Fitting and Rietveld methods, long before others realized the impact. We were the earliest to create patterns from structures which showcased the importance of pattern simulation. We can claim the k-alpha cursor’s many uses as part of our contribution to the XRD community. We started out by building tools that we wished existed for ourselves and our fellow XRD community. We continue on this path today. Our products are used for analysis on every continent in the world (yes, even Antarctica) and across a broad spectrum of fields of research, education and exploration.
MDI is best known for JADE and is used in labs wherever X-ray powder diffraction data are explored. MDI software works universally with every manufacturer of XRD equipment to help provide unbiased results. The major components of Jade available along with ICDD date base are as follows:
WHOLE PATTERN FITTING + RIETVELD: Quantify weight percentages and identify minor phases quickly and easily. JADE even automates these tasks as soon as you load your pattern.
SIMULATION AND VISUALIZATION: Simulate patterns to create your own custom database. Better visualize a structure in dimension with motion. Visual cues throughout to better help you and your team understand the materials you are analyzing.
CLUSTER ANALYSIS: Sorting through lots of similar patterns is easier to find outliers with our extensive cluster toolset. Use cluster analysis to find emerging patterns across your data.
FLEXIBLE MULTI-SEAT LICENSE: We make it easy to collaborate with others. With a flexible multi-seat license a large team can share a license across seats by determining the number of concurrent users. Additional savings can be achieved through a multi-year licensing plan that provides the benefit of always having up-to-date tools for your team.
JADE WORKS THE WAY YOU DO: We know you’re busy, always learning new methods and that you need to work with others. We’ve built JADE around how you work today – to help you get your work done faster and to try out the latest ideas in the world of X-ray Diffraction.
ONE-CLICK ANALYSIS: Automate your analysis with JADE. In so many cases, it’s just one click and you’re done. Often these results are better than those an experienced analyst could report and in a more timely manner. At the very least our One Click Analysis™ serves as an excellent starting point for further in-depth analysis.
Vivertana not only provides the Indian fraternity easy purchasing access to the ICDD data base but also assist in installation, training of personnel on the handling and usage of the ICDD database ( along with JADE software). Vivertana can also provide consultancy services to industry to assist in characterization of products and technical advice towards the desired products for the industry.
