TOOLS & TECHNIQUES UPDATE

NMR guide K.J.D. MacKenzie and M.E. Smith address the application of solidstate NMR spectroscopy to a diverse range of materials in Multinuclear Solid-State Nuclear Magnetic Resonance of Inorganic Materials. The book begins with sections on the theory and practice of NMR for nonspecialists. A current treatment of the use of NMR in inorganic materials research is provided for more experienced researchers. The book covers new developments in the range of nuclides used, and advances in hardware and software, providing a useful guide to researchers whatever their level of expertise.

Testing CD-ROM AMETEK Lloyd Instruments’ interactive educational CD-ROM, the Materials Testing Interactive Training Tool is designed for students, small enterprises, and those wishing to update their knowledge. The tool shows the benefits of materials testing, how tests are set-up, and industry applications. The CD-ROM includes interactive text and images, explanations of materials characterization, and video clips from experts in the field. Virtual rooms showcase AMETEK Lloyd Instruments’ latest equipment and software. Developed in partnership with the University of Exeter, UK, the tool is currently free of charge.

Veeco Metrology Group announces the Wyko® NT1100 Optical Profiler for quantitative surface topography measurements. Using non-contact interferometry, surface measurements from 0.1 nm to 2 mm are provided in three-dimensions with Angstrom resolution.

XRD data platform The XRDML data platform introduced by Philips Analytical is designed for its X’Pert range of X-ray

XY stage and software for rapid measurement of large

diffraction (XRD) software packages. New versions of X’Pert Data Collector, HighScore, and Epitaxy are available, with X’Pert Plus, Industry, and Stress to follow later in the year. XRD measurement data is stored in ASCII format in files based on standard XML language.

The NT1100 offers speed, repeatability, and accuracy at all magnifications, without compromising vertical resolution. A Data Stitching option provides a motorized surface areas. The NT1100 is intended for use in R&D,

Self-organization Significant progress has been made over the last decade in understanding the mechanisms that drive the spontaneous ordering of semiconductor alloys during epitaxial growth. A detailed account of this research is provided in Spontaneous Ordering in Semiconductor Alloys, edited by Angelo Mascarenhas. The self-organizing process modifies the structural, electronic, and optical properties of semiconductor alloys. Understanding this process may lead to control of these properties.

The files include all the information required to

quality inspection, failure analysis, and process control,

reproduce the experimental data, including instrument type and settings. This allows complete traceability of results and users to share measurements with others.

Dilution refrigerators Oxford Instruments’ new range of dilution refrigerators

Cool crystals

can obtain base temperatures as low as 15 mK. The KelvinoxMX (Multiple eXperiment) range will have

dilution unit that offers three choices of cooling performance.

The Helijet is a patented open-flow helium blower from Oxford Diffraction Ltd. that can cool single crystals for X-ray diffraction to less than 15 K. Cooling to these temperatures can improve the scattered diffraction signal by quenching crystal lattice thermal motions. It also minimizes radiation damage of vulnerable organic molecule crystals, prolonging their life. In tests at the European Synchrotron Radiation Facility (ESRF), a base temperature of 11 K was achieved at the sample position, and a root-mean-square temperature stability of ±0.5 K was demonstrated at 15 K over a period of one hour.

applications from nanotechnology to quantum computing, and is designed for integration into Oxford Instruments’ magnetic field-ULT (B-T) environment systems. The system comprises three modules. The primary insert provides a 50 mm line of sight access into which the second component, a range of experimental inserts, can be introduced. Interchangeable inserts allow for rapid sample turnaround. The third component is the
