WORKSHOPS - Monday & Tuesday 30–31 July
The exact date & time of each workshop will not be determined until April 2007.
XRD & XRF
There are many X-ray optics available to spatially restrict X-rays for use in X-ray spectrometry. Each optic has its own characteristics, capabilities, advantages and disadvantages and unique application niches. This workshop will provide basic knowledge about X-ray optics specifically multilayer optics, polycapillary optics, doubly-curved crystal optics, and monocapillary optics. One of the objectives in this workshop is to help users understand the basic working principles and performance characteristics of these optics. Attendees will learn the function of an X-ray optical system in selected applications and their capabilities.
Fundamentals and Applications of Neutron Scattering for Characterizing
Structural Materials and Components
Application of neutron diffraction in characterizing engineering materials in North America is becoming increasingly prevalent due to (a) the unique ability to provide microscopic insights to the physical and mechanical behavior of advanced materials and components and (b) the major investment made in new neutron scattering facilities at NIST, Los Alamos and Oak Ridge.
This workshop will provide a set of lectures and discussions on the fundamentals and applications of neutron diffraction that are relevant to the field of structural materials research. The presentations are intended for new users and engineers/scientists who are interested possibly using neutron scattering as a tool to their structural materials and engineering research and development. Specific topics will include:
Use X-rays? If so, try neutrons!
Two-dimensional diffraction data contains abundant information about the atomic arrangement, microstructure and defects of a solid or liquid material. In recent years, usage of two-dimensional diffractometer has dramatically increased in academic researches and various industries. This workshop covers recent progress in two-dimensional X-ray diffraction in terms of detector technology, geometry, and configuration of the two-dimensional diffractometer and various applications such as phase ID, texture, stress, crystallinity, combinational screening and thin film analysis.
Diffraction Peak Broadening and Peak Shape Analysis
Topics to be covered include:
Small Angle Scattering
The purpose of this workshop is to attract new people to the field—particularly those that may be wondering whether
this is a useful technique for their application. The format will be tutorial in nature. It will be divided into three parts:
Rietveld Applications (Full day)
Instructors & description to be announced.
X-ray Crystallography without Crystals
Countless materials of technological and scientific importance (catalysts, composites, nanoceramics, drugs, minerals, etc.) are not like regular crystals, which possess long-range translational symmetry, due to the presence of a substantial intrinsic disorder and/or their very limited (nanometer) size. The powder diffraction patterns of such materials show a few Bragg-like peaks and a pronounced diffuse component rendering traditional crystallography difficult to apply. The workshop will illustrate the recent advances and inherent limitations of traditional (Bragg) diffraction, and concentrate on the nontraditional total (Bragg and diffuse) scattering and Pair Distribution Function approach in structure studies of anything but regular crystals.
Analysis of RoHS/WEEE Elements
The EU RoHS Directive prohibits the import of consumer electronics containing Pb, Hg, Cr6+ or PBB and PBDE (Br compounds) at levels over 0.1% or Cd at levels over 0.01%. Versions of the RoHS Directive exist for China, Japan, India and other parts of the world. XRF has been highlighted as the screening technique of choice for producers and enforcers for the thousands of homogenous materials that require testing. The IEC-ACEA and XRF manufacturers have developed procedures for screening these regulated substances, from raw materials to end-products to recyclables (ELV and WEEE). This workshop will give an overview of the RoHS and Pb-free Directives along with practical, real-world XRF screening solutions for manufacturers and regulators alike.
XRF Sample Preparation (full day)
This workshop will start with a description of sampling techniques and equipment from bulk samples through the specimen prepared for analysis (Tully). A discussion of basic and fundamental considerations with respect to sample preparation for XRF will follow (Anzelmo). The morning session will be concluded by a discussion of the pertinent physical and chemical properties to be considered for metals preparation (Feret). The afternoon will begin with a discussion on the preparation of liquid samples (Arias), followed by a presentation on the basics of fusion (Daigle).
This workshop provides a basic introduction to the principles of XRF, and is specifically aimed at those new to the field. It will consist of a general overview of the technique, followed by more specific details of the basic principles with emphasis on understanding how to use XRF and what its capabilities are. A few particular applications will be presented to provide an understanding of how the basic principles affect actual practice.
Quantitative Analysis I & II (full day)
Energy Dispersive XRF
The Energy Dispersive X-ray Fluorescence (EDXRF) workshop provides a comprehensive review of XRF spectroscopy for both the beginner and experienced X-ray spectroscopist. Topics to be covered are instrumentation including sources and detectors, spectral processing, and qualitative and quantitative analysis. Applications will be discussed for “bulk” ED-XRF and “micro” ED-XRF analyses.
The workshop provides basic info rmation on available XRF techniques including conventional XRF and TXRF for trace element determination, sample preparation from classical to modern trends as dried spot method for trace analysis:way beyond microliters, definition of detection limits and Improving the detection limits and a large variety of application and info rmation of trace element levels and their importance in biological systems. Impact and importance on a wide range of materials including environmental and biological systems will be given.
