In modern society where our daily environment is supported by various electronic devices, it is critical to pursue opto-electronic or power-electronic devices with less environment impact and with higher efficiency of energy conversion to ensure a sustainable society. GaN (gallium nitride) and related materials have been a focus of attention...
Although high-resolution X-ray diffraction (HR-XRD) has been commonly employed for the crystallinity characterization of GaN-related materials, special care is required due to the complexities resulting from peculiar features in GaN-related materials, as explained in the preceding article.
General explanation for the application of HR-XRD techniques to the characterization of semiconductor...
A current trend in drug delivery systems is the use of multicoated or orodispersible tablets. These new systems increase bioavailability and can improve patient compliance by removing the need to swallow. The functionality of these structured tablets is sensitive to fluctuations in the manufacturing process. The chemical formulation is important...
The previous article described data collection. When data collection is done, the next step is to determine the structure. This article discusses critical points in structure analysis.
XRF (X-ray fluorescence) analysis as a technique is widely used in academia, research and development and industry as an analysis tool for the determination of elemental composition of materials. Unlike wet chemical and other instrumental techniques which require the use of hazardous chemicals and difficult preparation methods to dissolve samples...
The XRTmicron is a topography measurement system which can reduce measurement time by one order of magnitude compared to previous systems by using a new high-brilliance microfocus X-ray source, together with an X-ray mirror optical system and high-sensitivity/high-resolution X-ray camera designed for that source. Furthermore, it can automatically perform tasks...
The newly released wavelength-dispersive X-ray fluorescence sulfur analyzer, Micro-Z ULS (Ultra Low Sulfur) meets the current needs for the analysis of sulfur in petroleum.
The sulfur content in gasoline needs to be controlled in order to reduce air pollution, lengthen the lifetime of automobile catalysts, and improve engine reliability. Many...
In X-ray diffractometry, a variety of detectors are used depending on the purpose of the measurement. In recent years, in addition to the previously used 0D detectors (scintillation counters etc.), there has been increasing use of 1D detectors in which multiple detector elements are packaged into a single unit using...
The Rigaku PlateMate is a tool that allows one to mount SBS format crystallization plates on Rigaku goniometers for in situ diffraction experiments. Protein crystallography often requires screening large numbers of crystals to identify samples suitable for X-ray data collection. Traditionally, crystallographers mounted crystalline samples in capillaries — a time...
