Rigaku: Leading with Innovation X-ray Diffraction & Elemental Analysis
The Bridge
High-contrast, high-resolution computed micro-tomography
Rigaku has developed the nano3DX as a high-resolution 3D X-ray microscope that combines Rigaku's unique high-brightness rotating anode X-ray generator with a proprietary high-resolution CCD X-ray camera to provide high-contrast computed tomography at the submicron level. The nano3DX is able to observe an ultra-wide field-of-view while retaining high 2D/3D spatial resolution and providing improved density resolution compared to conventional X-ray microscopes.

Thanks to everyone who came by our booth at Pittcon this month. It was great to see so many familiar faces and, of course, new ones too. In April, we invite members of the geosciences community to come see us at AAPG Annual Convention & Exhibition (CE) at the George R. Brown Convention Center in Houston (April 2 – 5, Booth 1415). Also, we will be at the ACS Spring conference at the Moscone Center in San Francisco (April 2 – 6, Booth 1308). There is a link to a complete list of events below.

This month's issue contains three special feature articles. The first is "The NEX Story," which describes the origins of the EDXRF group in Austin, TX. The second paper reports on the recent thermal analysis workshop organized by Korea ITS (KITS), Rigaku's distributors in Korea. Finally, the career of Dr. Stanislav Ulitzka is detailed in an excellent piece by Dr. Cameron Chai of AXT.

The NEX Story
By Scott Fess, EDXRF Product Manager, Applied Rigaku Technologies, Inc.

Rigaku established Applied Rigaku Technologies, Inc. (ART) in Austin, Texas in 2009. ART—as the Rigaku EDXRF Center of Excellence—has brought modern, innovative design into the 21st century with the NEX series of EDXRF analyzers. President and CEO Robert Bartek built the ART organization around the core team from the original ASOMA Instruments in Austin – the core group that has been at the forefront of benchtop EDXRF design and application since the 1980s. Applied Rigaku Technologies continues this tradition at Rigaku, designing and manufacturing all EDXRF systems in Austin. Full article >

Analysis of Metals in Aerosols on Air Filters
Applied Rigaku Technologies

Element analysis of aerosols and particulate matter released in smokestacks and other industrial gas discharge is vital to ensure that environmentally acceptable levels of toxic and hazardous elements are released properly into the air. Monitoring smoke or other gaseous waste is important in many areas, such as industrial manufacturing, coal-fired power plants, chemical and plastics production, etc., in order to minimize air pollution and the release of toxic metals in compliance with US EPA and other world and regional or local governing regulations. As a tool to help ensure compliance and proper release, Rigaku offers the NEX DE EDXRF analyzer with 60 kV excitation source and high resolution and throughput Si Drift Detector, giving the analysts and technician alike a fast, simple, yet powerful means for monitoring elemental analysis of air filters.

March 15, 2017. Researchers have developed a groundbreaking one-step, crystal growth process for making ultra-thin layers of material with molecular-sized pores. Researchers demonstrated the use of the material, called zeolite nanosheets, by making ultra-selective membranes for chemical separations.

March 20, 2017. Thanks to the discovery of a new material, a cooking pan could generate enough electricity to charge a cellphone in just a few hours. The team found that a combination of the chemical elements calcium, cobalt and terbium can create an efficient, inexpensive and bio-friendly material that can generate electricity through a thermoelectric process involving heat and cold air.

March 21, 2107. Physicists announced that they had successfully simulated a material called fullerite — harder than diamonds — which could someday revolutionize electronics, nanotechnology and materials science. Using computer and X-ray simulations, researchers at the Technological Institute for Superhard and Novel Carbon Materials (TISNCM) should be able to build the ultra-hard material.

March 27, 2017. Not only have scientists from Ibaraki University (Japan) performed the first non-destructive morphological observations on the Fleshy brittle star, Asteronyx loveni, using micro X-ray tomography, but they also published their research as the first study supported via crowdfunding in the Asian country.

March 28, 2017. Vantablack® (a special coating developed from an amalgam of carbon nanotubes measuring 20 nm) in a spray-on form has been released. The blackest material's "spray-on" form is capable of blocking 99.8 percent of infrared, ultraviolet, and visible light. However, like the original, it may not be able to give the perception of a 3D object in the 2D form.
