Introduction

IN THE NEWS

October 4, 2022: Billions of years ago, a version of our Earth that looks very different than the one we live on today was hit by an object about the size of Mars, called Theia. Most theories claim the Moon formed out of the debris of this collision, coalescing in orbit over months or years. A new simulation puts forth a different theory—the Moon may have formed immediately, in a matter of hours, when material from the Earth and Theia was launched directly into orbit after the impact.

October 24, 2022: A paper recently published in the journal ACS Energy Letters reviewed the role of isostatic pressing (ISP) in large-scale solid-state battery (SSB) production. ISP is a process that covers most of the processing conditions required for the large-scale production of solid electrolyte materials. ISP can be used to generate dense, thin solid electrolyte layers used in practical SSBs. Moreover, the technique offers a pathway toward the integration of the solid electrolyte, anode, and cathode layers into a tri-layer, dense system for commercial applications.

October 25, 2022: Solid-state batteries (SSBs), which have a simpler cell design and an anode-free arrangement, have been thought of as a potential next-generation storage concept for a few years. Pure lithium metal anodes in SSBs stand out for having the highest specific capacity and the lowest potential. However, their practical use in SSBs is still constrained by interface instability, the production of solid electrolyte interphase (SEI), a low critical current density, and separator penetration by lithium dendrites. Silicon has emerged as a promising anode material for SSBs, according to a paper recently published by two scientists from Germany.

October 25, 2022: Stradivarius violins produce elegant music with a level of clarity that is unparalleled by modern instruments, according to some musicians. And it's the finishing touches—mysterious treatments applied hundreds of years ago by Antonio Stradivari—that contribute to their unique look and sound. In a step toward unraveling the secret, researchers report on a nanometer-scale imaging of two of Stradivari's violins, revealing a protein-based layer between the wood and varnish.

October 25, 2022: In a study that confirms its promise as the next-generation semiconductor material, UC Santa Barbara researchers have directly visualized the photocarrier transport properties of cubic boron arsenide single crystals.

Podcast

As the Opioid Crisis continues to ravage the country, what is being done to solve the prevalence of these drugs in our communities? In this episode we are honored to be joined by Retired DEA Special Agent Steve Murphy.

Join us as we discuss:

  • How has the war on drugs changed since his time in Colombia?

  • The role China has played in the production and manufacturing of synthetic opioids

  • How state supported injection sites are changing the conceptions of drug use in America

  • The failure of the Portugal model

  • The importance of diplomatic engagement when it comes to solving the Opioid Crisis

NEW FEATURED PRODUCT

X-ray diffraction can be used to determine if there are trace crystalline phases in a sample. However, this analysis can be difficult when there are transition metals in the sample because these materials increase the overall background, making small peaks harder to detect and quantify. The new XSPA-400 ER detector, which is available as an option on Rigaku’s flagship SmartLab multipurpose diffractometer, as well the SmartLab SE, suppresses these increases in background intensity using high energy resolution, allowing highly sensitive measurements in samples such as iron and steel, as well as battery materials. The XSPA-400 ER, when integrated with the SmartLab Studio II software package, can easily switch between 0-, 1-, and 2-dimensional measurements under computer control, making it highly versatile and suited to measuring a wide range of samples, from powders and bulk materials to thin films. It is a photon counting detector with linear response up to a very high count rate that can be used for operando, in situ, and 2D stress measurements, and more.

FEATURED APPLICATION NOTES

How to Evaluate Solid Pharmaceutical Drugs (3) – Confirming Hydrates –

Rigaku Corporation


Solid pharmaceutical drugs are known to have different physical properties—such as solubility, bioavailability, and stability—depending on their crystal form. Although hydrates and anhydrides are related as so-called pseudo-polymorphs, they have different physical and chemical properties, such as stability regarding temperature, atmosphere, humidity, pressure, etc. In general, for example, hydrates are known to melt faster than anhydrides. Confirming the presence/absence of pseudo-polymorphs and the differences in their properties is essential to maintain the quality of APIs and products, and to avoid problems in the formulation process.

This application note introduces the results of TG-DTA, powder X-ray diffraction, and simultaneous XRD-DSC measurements of theophylline (an asthma agent) anhydride and monohydrate. We also will introduce the measurements results of an antiallergic agent, nedocromil sodium, measured with a simultaneous XRD-DSC measurement system with a humidity generator attached.

Analysis of Cement and ASTM C114 Qualification

Applied Rigaku Technologies


Cartesian Geometry EDXRF performance is demonstrated for the analysis of finished ortland cement and ASTM C114-18 qualification.

EDXRF is a simple analysis technique used in cement plants around the world. The technique is ideal for QA/QC throughout the cement production process. EDXRF can be used as a screening tool and a QA/QC analyzer to ensure proper quality of incoming feedstocks, raw meal mixture balances, the addition of gypsum, and throughout the manufacturing process, including analyzing alternative fuels and ULSD used for firing the kilns.

Rigaku NEX CG II complies with the performance required in ASTM C114 and makes an excellent backup analyzer to WDXRF or as the main analyzer when producing Portland cement.

Fused Bead Analysis for Wide Concentration Ranges of Various Oxide Materials Using OXIDE-FB-PAK

Rigaku Corporation


The fusion method in X-ray fluorescence (XRF) analysis is an effective sample preparation technique for getting accurate analysis results of powder samples, since the technique eliminates heterogeneity due to grain size and mineralogical difference. In addition, the homogenization of material property by vitrification makes it possible to expand the calibration range by the use of synthetic standards of fused beads with reagents or by using diverse reference materials.

Rigaku provides an analysis package for various oxide materials by the fusion method, named "OXIDE-FB-PAK". his application note introduces OXIDE-FB-PAK and demonstrates analysis results using this analysis package.

MATERIAL ANALYSIS

Are Chemical Munitions Duds?

If doctrine serves as a template, persistent agents will channelize movement and serve as a terrain denial tool. Non-persistent agents will generate chaos and incapacitate. Technology designed to provide early warning detecting aerosolized chemical warfare agents will provide a population just enough time to mask and seek shelter from the threat.


But what happens if not all the munitions detonate as designed? What happens when the caustic chemical reacts with a metal casing after the munition was filled in the 1980s or 1990s? The result is a higher-than-normal dud, or unexploded ordnance (UXO) rate, littering the battlefield undetected by early warning sensors.
