Summary: With the Angle Resolved XRF (AR-XRF) technique, the intensity of the characteristic elemental fluorescence signal of a sample can be affected by the geometry of analysis at different angles of detection and irradiation. This technique has been proven to be useful in analyzing metallic bilayer samples. In this paper, AR-XRF was applied to study a glazed ceramic from Puebla, Mexico, in the field of Cultural Heritage. The analysis of the decorations revealed the limitations of the technique, especially for thick and diffused layers, highlighting the importance of prior knowledge in retrieving structural information in complex systems with numerous variables.

Summary: Solid polymer/ceramic composite electrolytes show promising potential for batteries due to their thermal stability and mechanical properties. Chemical heterogeneity in these materials, such as inhomogeneity in ceramic phases and salt distribution at interfaces, plays a crucial role in their performance. Through advanced imaging techniques, this study reveals nanoscale chemical heterogeneity in composite electrolytes and highlights the need for further research to understand the relationship between chemical heterogeneity and ionic transport pathways.

Summary: The research focuses on using agricultural waste like Cymbopogon flexuosus plant shoot as reinforcement in biocomposites due to its abundance and eco-friendly nature. Carbonized CFPS is rich in SiO2 and hard ceramic particles, making it a feasible reinforcement option. Non-carbonized CFPS, on the other hand, has a semi-crystalline nature and can serve as a filler or substitute for silica-based inorganic fillers.

Summary: A new automated method based on statistical threshold is proposed to remove diffraction peaks from multiple-detector spectra, which retains more fluorescence data and increases the information content available for diffraction-free elemental quantification and mapping. The proposed method does not require an increase in dwell times or additional data to be collected to compensate for the removed fluorescence data.

Summary: Adding CaCl2 to the salting solution can improve the quality of salted separated egg yolk by affecting the composition and structure of HDL and LDL. CaCl2 improves the orderliness of HDL structure, loosens the LDL structure, weakens the aggregation behavior of HDL, and prevents HDL and LDL from participating in the formation of a three-dimensional gel structure.

Summary: This paper presents the development of a laboratory M mu-XRF spectrometer for X-ray tubes with high resolution and low detection limit. The spectrometer consists of polycapillary X-ray lenses and a flat crystal, which convert divergent broadband X-rays into quasi-parallel X-rays and obtain monochromatic X-rays through crystal diffraction. The monochromatic X-rays are then focused by a polycapillary half-focusing X-ray lens to provide spatial resolution for fluorescence analysis. The spectrometer is capable of detecting elements such as Se with a detection limit of 52 μg/L and light elements like Mn with a detection limit of 970 μg/L.

Summary: The REgolith X-ray Imaging Spectrometer (REXIS) instrument on the OSIRIS-REx mission to asteroid Bennu is a student collaboration experiment designed to detect fluoresced X-rays from the asteroid's surface. However, due to low solar X-ray flux during observation periods, REXIS data did not show a clear X-ray fluorescence signal from the asteroid. In-flight calibration also unexpectedly detected the transient X-ray binary MAXI J0637-430 during Bennu observations.

Summary: Scanning transmission X-ray microscopy (STXM) allows imaging of biological specimens and collection of localized spectroscopic information through X-ray fluorescence (XRF) and/or X-ray Absorption Near Edge Spectroscopy (XANES). Recent publications in synchrotrons have utilized soft X-ray spectro-microscopy in life science and environmental research to explore complex metabolic mechanisms by tracing chemical elements involved in metabolic pathways.

Summary: X-ray fluorescence spectroscopy is a powerful tool for elemental analysis, but it traditionally cannot quantify light elements. The use of scattering X-ray radiation is becoming popular in X-ray studies, with the trend being towards standard XRF instrumentation. This study explores the use of monochromatic radiation and varying incident angles to obtain physical and chemical information on plastic samples, utilizing machine learning techniques for regression modeling.

Summary: This study used X-ray fluorescence to analyze the presence of metals in 56 children's plastic toys, with titanium, chlorine, zinc, silicon, iron, and copper being the most frequently detected elements. The study found that some toys may pose health risks to children due to the presence of metals, and suggested that the toys may be made of PVC based on the high frequency of chlorine presence. Further research is needed to verify the roles of titanium and silicon in toys and to identify associated health risks. No toxic elements such as lead, cadmium, and arsenic were detected in the toys analyzed.

Summary: Cobalt nanowires were synthesized with varying spacing-to-diameter ratios, and it was found that the easy magnetization direction switches from parallel to perpendicular to the nanowire growth direction under certain conditions. The magnetic interactions among the nanowires were mainly through dipolar interactions, resulting in additional uniaxial anisotropy. Further reduction in spacing-to-diameter ratio led to isotropic behavior in the nanowires' magnetic properties.

Summary: Chemical treatment of skeletal remains can reduce overall DNA quality and quantity but has no significant impact on stable isotope ratio analysis. Examination of treated and untreated human remains through histological and stable isotope analysis reveals that treated remains exhibit better preservation compared to untreated remains. Stable isotope ratio analysis is viable for both treated and untreated remains, regardless of their origin.

Summary: This paper presents the outcomes of a microcontextual geoarchaeological study conducted on earthen dwellings from the Early Iron Age village of Cerro de San Vicente. The study employed soil micromorphology, lipid biomarker analysis, XRD, and XRF analyses to investigate various aspects of the dwellings, including construction materials, site formation processes, and daily life practices. The results have shed light on the construction layers, floor use, maintenance, repaving, periods of abandonment and decay, and the presence of lipid biomarkers associated with dwelling functionality. The study significantly contributes to our understanding of ancient construction practices and the utilization of domestic spaces during the Early Iron Age.
