Celebrating 10 Years
of the SmartLab |
 |
| 2015 marks the 10 year anniversary of a revolutionary XRD product |
| The SmartLab is the most novel high-resolution diffractometer available today. Perhaps its most novel feature is the SmartLab Guidance software, which provides the user with an intelligent interface that guides you through the intricacies of each experiment. It is like having an expert standing by your side. Over the last ten years this product has been refined and enhanced to meet the challenges of the ever-changing field of materials science.

Welcome
For those of you who enjoy skiing (and live in the northern hemisphere), January is a great time to visit the mountains and partake of this sport. Riding up a ski lift in a heavy snow, it is hard not to contemplate the structure of snowflakes, with the unlimited diversity of forms based on the underlying similarity of structure. Through the snowflake nature teaches us about the variation in materials that can be formed from differences of formation conditions. An even better place to contemplate the wonder of snow is to do so sitting in an outdoor Japanese hot
spring, or onsen, where the snowflakes meet their demise as they fall into the steamy volcanic waters.
Enjoy the newsletter.

Thin Film Training Textbook
High-resolution X-ray Diffraction Method (Part 13)
Rigaku Corporation
Last month, we derived the fundamental equation that must be satisfied by an X-ray wave in a crystal. This month we discuss the boundary conditions that must be satisfied when the incident X-ray wave enters the crystal from a vacuum (or air) and when the diffracted X-ray wave and transmitted X-ray wave exit the crystal. The second section describes the two-wave approximation. In preparations for calculating the rocking curve, the third section this month discusses the relationship between the amount of the shift of the incident angle from the diffraction condition and the electric fields of the incident and diffracted waves for the Bragg case.

Featured Rigaku Journal Article
CALSA: High-resolution spiral analyzer for high-resolution powder XRD
Application Laboratory, Rigaku Corporation
Multi analyzing crystal detectors (MCA) have been implemented at synchrotron radiation facilities, e.g. High Energy Accelerator Research Organization (KEK) in Japan and Diamond Light Source in UK. They consist of more than two single crystal analyzer crystals with point detectors. This design accelerates data acquisition thanks to the multiple detectors, and
generates a narrower peak profile due to the analyzer crystals. The CALSA detector follows and expands the MCA design.
It consists of 10 germanium single crystal analyzers combined with a 1-D silicon strip detector. It provides the sharpest peak FWHM
(0.017°) among the laboratory based powder X-ray diffractometers.

EDXRF Application Note
Chlorine and ash in biomass
Applied Rigaku Technologies
Biomass refers to dry plant matter. Biomass is used as a feedstock in the pulp and paper industry as well as in the production of biofuels. Biomass is also an increasingly popular primary or secondary fuel at power plants and cement kilns. Ash consists of the metal oxides and heavier elements that remain after combustion removes the organic, gaseous and volatile components. Biomass combustion properties depend in part on the ash content, and prior to incineration chlorine levels must be at safe, low levels. EDXRF offers a fast and simple low-cost method of measuring the chlorine content and predicting the % ash content, without the need for radioisotopes or long combustion analytical methods.

Customers in the Spotlight
BioSAXS-1000 at the Laboratory of Professor Alba Guarne, McMaster University, Hamilton, OT, Canada
Professor Guarne's interest is related to protein/protein and protein/DNA interactions that regulate DNA replication and DNA repair. SAXS is very useful tool to figure out the overall characteristics and stoichiometry of these complexes. Although SAXS measurements can be done at a synchrotron too, having SAXS in the lab allows her to choose best buffer conditions for the analysis and speeds up her overall research workflow.

Scientific Book Review
X-rays and Crystal Structure
By W. H. Bragg and W. L. Bragg, G. Bell and Sons, London, 1915.
This book was published the year after the start of World War I and only three years after the discovery of X-ray diffraction by Max von Laue. It appeared about six months before W. L. Bragg (the son) was sent to France. While he was there, working out how to locate German artillery positions by
"sound-ranging," he learned he had won the 1915 Nobel Prize with his father (W. H.). W. L. was 25 and is still the youngest Nobel Laureate in the sciences. For more > |
