“…The XRF spectra provided excellent information about the elemental chemical compositions of the glaze phases of the ceramic tiles that allowed comparisons between the compositions of the different colored glazes [8,22,23]. The thicknesses of the glaze layers affected the results of the analyses.…”

The walls of the Alcazar Palace in Seville have been covered with ceramic tiles of different styles that were manufactured with different techniques. Several studies have been carried out on these ceramics, but no interest has been paid to the tiles manufactured by the workshop of the Valladares family, one of the most productive ceramic workshops in Triana (Seville). In this work, tiles that were made in the Valladares workshop are studied for the first time. The tiles from the Cenador del Leon built in 1645–1646 were chosen. The experimental studies suggest that the ceramic body was manufactured with silico-calcareous clay. This raw material was heated to a temperature of ca. 900 °C. A nondestructive and on-site analytical procedure was applied first. Microsamples were also taken and studied through microanalytical techniques. The maiolica style was used by Benito de Valladares for tile manufacture. The glaze phases were constituted by two layers. The pigments and doping elements used to obtain different colors were characterized. Valladares’ work is considered as a continuation of Augusta's work; therefore, a comparison between both ceramists has been realized to better understand the ceramics production in southern Spain during the sixteenth to seventeenth centuries.

Energy demands are increasing day by day because almost all equipment that supports human activities uses electrical energy. CIGS solar cells are an energy source that is environmentally friendly, renewable, and has high efficiency. Selenium is one of the materials used in making solar cell CIGS. However, researchers often find the problems of this material hard to dissolve compared to other materials (copper, indium, and gallium). Therefore, in this study, pure selenium will be synthesized to produce selenium dioxide (SeO2) as a material for making solar cell CIGS with electrodeposition. The XRF showed the resulting selenium dioxide of 99.077%, SEM-EDX showed At% selenium from SeO2 greater than pure selenium, XRD showed CIGS orientation on (211) and (105).

“…[119] The scanning system operates by scanning the sample point by point in both the X and Y directions, which is constrained by the mechanical motion of the sample stage and the X-ray collimation. [119,120] Scanning macro-XRF (MA-XRF) imaging allows the visualization of elemental distribution in large areas of a macroscopic sample and records the analysis of each point in the XRF spectrum. [121,122] X-ray diffraction (XRD) mapping records the diffraction patterns at each pixel of the sample area and allows for the visualization of the spatial distribution of crystalline phases in the sample.…”

This article discusses the basic principles, methodological features, instrumental characteristics, and practical applications of X‐ray techniques in cultural heritage. X‐ray techniques are a set of well‐defined methods for determining the chemical composition and properties of samples. In the field of cultural heritage, material characterization provides valuable information on archaeological materials for understanding heritage assets and ensuring their sustainability. X‐ray fluorescence (XRF) is a versatile method for qualitative and semi‐quantitative elemental analysis. X‐ray diffraction (XRD) is a characterization method to define the properties of the crystal structure of materials. X‐ray photoelectron spectroscopy (XPS) is a chemical tool for understanding the surface chemistry of materials. X‐ray absorption fine structure (XAFS) is a powerful probe for determining the local atomic environment of individual atomic species. X‐ray imaging methods are used for visualization and examination of the objects under study, including X‐ray radiography (XRR) for the non‐destructive inspection of objects, X‐ray computed tomography (XCT) for revealing the internal structure of materials, and dual‐energy X‐ray absorptiometry (DEXA) for the diagnosis of bone health. X‐ray techniques represent key analytical techniques in archaeometric investigations and provide valuable insights into the cultural significance of artifacts.
