AUGUST 2022, ISSUE 110

WELCOME

In August, we returned to in-person attendance at two of our regular trade shows for the first time since the beginning of the pandemic. Early in the month, we went to the Denver X-ray Conference in Rockville, MD and, more recently, to the ACS Fall Meeting in Chicago, IL. Both were well-attended and busy events.

September will be a very busy month for in-person conferences. Below we highlight some of the major events at which Rigaku will be in attendance as exhibitors.

DXC Conference

The Summer 2022 issue of the Rigaku Journal is now available on the Rigaku website. This issue features two lengthy technical articles and a new product article. See below for an introduction to these articles and links to the website where you can read more.

Aya Takase has been producing educational webinars about X-ray imaging (also known as X-ray computed tomography) for the past few years. Currently she is producing a series of workshops. A recent installment, featured below, looks at segmentation of rocks to explore the open and closed pores they contain.

The Rigaku Analytical Devices division presents a podcast discussing fentanyl and its role in the opioid crisis. The group has also released an update to the software used in their ResQ CQL handheld Raman devices.

The featured application notes this month explore crystallite size analysis of a catalyst material by the Scherrer method (XRD) and quality control and quality assurance of complex lube oils by EDXRF. We also highlight a few recent news reports pertaining to materials analysis that we hope are of interest to you.

IN THE NEWS

August 17, 2022: Researchers have developed a new moisture-driven electricity generation device made of a thin layer of fabric, sea salt, carbon ink, and a special water-absorbing gel. The device works by keeping one end of the fabric dry, while the other end is perpetually wet. The difference in moisture content of the wet and dry regions of the carbon-coated fabric creates an electric current. This rechargeable fabric-like battery can produce electricity for more than 150 hours and provides higher electrical output than a conventional AA battery, potentially powering everyday electronics.


August 18, 2022: Newly discovered magnetic interactions in the Kagome layered topological magnet TbMn6Sn6 could be the key to customizing how electrons flow through these materials. Scientists have conducted an in-depth investigation of TbMn6Sn6 to better understand the material and its magnetic characteristics.


August 24, 2022: Engineers have designed a battery made from inexpensive, abundant materials, that could provide low-cost backup storage for renewable energy sources. Less expensive than lithium-ion battery technology, the new architecture uses aluminum and sulfur as its two electrode materials with a molten salt electrolyte in between.


August 24, 2022: Engineers have developed a method to use disposable personal protective equipment (PPE) to make concrete stronger, providing an innovative way to significantly reduce pandemic-generated waste. The team is investigating the feasibility of recycling three key types of PPE—isolation gowns, face masks and rubber gloves—into concrete.

Compact X-ray Diffractometer MiniFlex XpC

X-ray diffraction (XRD) has traditionally been utilized mainly in the R&D field. Recently, however, opportunities to use XRD in the QA/QC field are increasing since the XRD technique has become easier to use with the popularization of desktop X-ray diffractometers and high-speed 1D semiconductor strip detectors (1D SSD). Rigaku has marked another step in this trend by announcing the MiniFlex XpC, a compact X-ray diffractometer optimized for QA/QC, utilizing the X-ray technologies cultivated in the company’s 70-year history.

There are three requirements for the manufacturing environment: 1. shorter measurement time, 2. better operability, and 3. higher durability. The MiniFlex XpC meets these requirements thanks to its downsized X-ray generator (XG), high-speed 1D SSD D/teX Ultra 250 detector, a new sample loading function, software optimized for QA/QC, connectivity with a third-party automation system, a high-precision theta-theta goniometer, and so forth.

Quantification Analysis of Cement Materials
Atsushi Ohbuchi, Takahiro Kuzumaki, Miki Kasari and Tetsuya Ozawa
X-ray diffractometry is widely used for quality control and process control in cement. This article presents an accurate and precise quantification method for free lime in a clinker material and an accurate quantification method of the admixtures in a blended cement. The partial accumulation measurement was used to make a calibration curve including a scale factor to improve the accuracy and precision of the quantitative method. Analytical result of free lime showed good agreement with its preparation value and had a small standard deviation. The reference intensity ratio method combined with the WPPF method was applied to admixture quantification in a blended cement for accurate quantification. The quantitative values of the admixtures in the simulation sample with a three-component system showed good agreement with the preparation values.

Three-dimensional modeling for complex structures based on small-angle X-ray scattering
Tomoyuki Iwata
Three-dimensional real-space modeling for hierarchical materials by matching experimental and simulated small-angle X-ray scattering patterns is proposed. The positional arrangements of small primary particles in the cell are estimated by the reverse Monte Carlo modeling and the simulated SAXS patterns are derived from these models. This modeling has been applied to the structural estimation of a silica aerogel sample. The pore size distribution derived from the obtained structure model is compared to the results of the transmission electron microscopy and gas adsorption measurement.

FEATURED APPLICATION NOTES

Crystallite size analysis of a catalyst material by the Scherrer method

Rigaku Corporation


The Scherrer method is a typical method for evaluating the crystallite size of powder samples. The method assumes that the broadening of diffraction peaks due to crystal lattice strain can be ignored, and calculates the crystallite size based on the fact that the crystallite size in the direction perpendicular to the lattice plane of the diffraction peak is inversely proportional to the full width at half maximum of the peak. Cerium oxide (CeO2) is a functional oxide nanoparticle used as a base material for exhaust gas cleaning catalysts and transparent electrolyte sheets. Since the performance of these materials depends on the particle size and crystallite size of the CeO2 nanoparticles, evaluating their sizes is very important. In this example, we measured the X-ray diffraction pattern of CeO2 nanoparticles and evaluated the crystallite size using the Scherrer method.

Complex Lube Oils

Applied Rigaku Technologies


Quality control and quality assurance during the lube oil blending and manufacturing process is essential. Basic lube oil formulations containing only P, S, Ca and Zn are often augmented with additional elements and additives to create lubricating oils for specific needs. A fast, simple method of analyzing lube oils is important throughout the QC/QA process. Rigaku meets this industry need with a high-performance, low-cost benchtop EDXRF system. Rugged and reliable, the NEX QC+ is an ideal tool for elemental analysis, with simple and intuitive software for the non-technical operator.
