ANGSTROM ADVANCED ADX-2500 X-RAY DIFFRACTION INSTRUMENT

ADX-2500 X-ray Diffraction Instrument
Introduction
ADX-2500 X-ray Diffraction Instrument is designed for application in the microstructure measurement, testing and in-depth research investigations. With different accessories and the corresponding control and calculating software,ADX-2500 is a diffraction system according to the practical requirements in many fields.
ADX-2500 X-ray Diffraction Instrument provides the structure analysis of single crystal, polycrystalline and amorphous sample.ADX-2500 is capable of the following: phase qualitative analysis and quantitative analysis (RIR, Internal standard calibration, External standard calibration, Additive criterion), pattern indexing, unit cell determination and refinement, crystallite size and strain determination, profile fitting and structure refinement, residual stress determination, texture analysis(ODF expresses three-dimensional pole figure), crystallinity estimate from peak areas, thin film analysis and others.
Features
  • Perfect incorporation of the hardware and software, allows ADX-2500 to perform different types of analysis for researchers from various fields;
  • High precision of the diffraction angle measurement allows ADX-2500 to obtain the more accurate data;
  • Higher stability of the X-ray generator control system provides excellent measurement accuracy;
  • Simple and effective design makes ADX-2500 convenient for operation and user friendly.
Software
General diffraction data processing: automatic peak search, manual peak search, integral intensity, separation of Kα1, α2, background remove, pattern smoothing and magnifying, multiple plot, three-dimensional plot and simulation of XRD pattern.
  • Profile fitting and overlapped peeks separation
    • With the help of Pseudo-Voigt or Pearson-VII function, the overlapped peeks could be separated to determine the parameters of the peaks and calculate the crystallinity, crystallite size and strain.
  • Qualitative Analysis
    • The data processing software has the search and match function on the base of whole profile and diffraction angle. The profile matching procedure employs the designed mode to do the qualitative analysis by reducing the search range from major, minor, to micro phase without indicating the diffraction angle. The diffraction angle matching procedure is based on the peaks position and intensity and usually used for the qualitative analysis of the data with large angle error.
  • Quantitative Analysis
    • After the phase composition is determined, the content of each phase could be calculated with the help of RIR or/and the Rietveld refinement (Quantitative Analysis without criterion).
  • Plot and Export
    • The data processing software is operated with Windows interface. The preparing exported pattern could be labeled, zoomed in, zoomed out and also copied and pasted.

The Path to Hydrogen: Producing clean, storable fuel from biomass

April 5th 2013 Boston, United States
North America Clean Energy, the leading magazine and internet media in Renewable Energy sector published again an article from us about our innovative collaboration of Hydrogen and Biomass technology. "A new application of hydrogen is being deployed which is helping solve humanity’s ever-evolving energy woes. Traditionally, hydrogen has a large number of applications – used in everything from industrial products to food packaging. Ammonia used in fertilizer and industrial processes amounted to 160 Million tons worldwide in 2011; hydrogen is a primary component in ammonia. The market demand for new, less expensive sources of hydrogen is driven heavily by fertilizer and manufacturing, however, a new market demand is emerging for hydrogen in another sector – energy. Power plants in Germany as well as Canada (using wind and natural gas, respectively) are today supplementing their primary electrical generators with advanced configurations of hydrogen technologies. These retrofits help the plants save money by smoothing supply, converting excess electricity generated into storable hydrogen gas which can be returned to electricity using a turbine generator or a fuel cell. " (The drawing is referred to a famous biomass manufacturer, Nexterra)

Descripción general del proceso de electrólisis

La electrólisis es el paso de una corriente eléctrica continua a través de una sustancia iónica que es ya sea fundido o
disuelto en un disolvente adecuado, dando lugar a reacciones químicas en los electrodos y la separación de materiales.
Los principales componentes necesarios para lograr la electrólisis son:
Un electrolito: una sustancia que contiene iones libres que son los portadores de corriente eléctrica en el electrolito.
Si los iones no son móviles, como en una sal sólida a continuación, no se puede producir electrólisis.
Una corriente continua (CC) Suministro directo: proporciona la energía necesaria para crear o descargar los iones en el electrolito.
La corriente eléctrica es transportada por electrones en el circuito externo.
Dos electrodos: un conductor eléctrico que proporciona la interfaz física entre el circuito eléctrico que proporciona la energía y la
electrolito. Los electrodos de metal, grafito y material semiconductor son ampliamente utilizados. Elección del electrodo adecuado depende de química
la reactividad entre el electrodo y el electrolito y el coste de fabricación.
