Summary: The yellow coloring of large Buddhist paintings during the late Joseon dynasty was analyzed using Raman spectroscopy and non-invasive component analysis. p-XRF analysis confirmed the use of gold, orpiment, and organic pigments, but not the yellow chromophoric elements of the organic pigments. Microscopic analysis revealed no particles or crystals, and the identification of light elements or organic compounds via p-XRF was challenging. Raman spectroscopy detected gamboge in the presumed organic pigments, either alone or mixed with white inorganic pigments.

Summary: Understanding the dynamics of phytoplankton in aquatic ecosystems is crucial for understanding their ecological roles. The morphological traits of phytoplankton can be used to assess their adaptability to different environments and estimate their niche width. However, the role of morphological plasticity in phytoplankton studies is often overlooked.

Summary: This article adopts a narrative perspective to explore Vincent van Gogh's understanding of creativity through his correspondence. The findings indicate that creativity is seen as a developmental process characterized by dedication and persistence, a relational process in the context of people and nature, an embodied action, and a force that oscillates between asceticism and socio-cultural participation.

Summary: Three artworks by Vincent van Gogh underwent technical examination before being exhibited. The examination revealed color changes in the paper and fading in the inks and pigments, prompting further analysis and investigation. The decisions made for their display took into consideration Tate's lighting policy and the display of preserved color beneath earlier mounts and frames. It was also discovered that van Gogh used two formulations with geranium lakes based on Eosin Y for the first time in one of his gouache paintings.

Summary: Yellow colourants were rarely used in ancient Chinese tomb mural paintings, but the recently discovered Tang dynasty murals in Xi'an provided new materials for studying yellow pigments. Analytical techniques revealed that goethite and vanadinite were the yellow pigments used in these murals, with vanadinite being even more uncommon. Chinese craftspeople had a history of working with iron- or lead-bearing minerals associated with these yellow pigments, suggesting no technological barriers to using yellow during the Tang dynasty. The absence of yellow colourants in Chinese tomb murals was likely a cultural choice rather than a technological one.

Summary: The Night Watch, painted by Rembrandt in 1642, is his most famous work and is displayed in the Rijksmuseum in Amsterdam. X-ray powder diffraction (XRPD) mapping revealed the presence of lead(II) formate in the painting, which was not previously reported in historical oil paints. Model oil paint media were prepared and analyzed to investigate the reactivity of lead driers in oil matrices, and lead(II) formate and lead(II) formate hydroxide were detected and mapped, providing new insights into historical paintings.

Summary: This study aimed to characterize the biogeochemical influences on tungsten mobilization in wolframite tailings through a high-resolution depth profile analysis. It was found that several indigenous bacteria associated with iron and sulfur were highly correlated with tungsten, arsenic, and rare earth elements in the tailings. The weathering of wolframite was accelerated by the biooxidation of metal sulfides, which resulted in the mobilization of tungsten species. The study also highlighted the potential economic value of reprocessing tungsten waste for valuable metal recovery.

Summary: When studying paintings with active infrared thermography (IRT), lock-in thermography (LIT) showed advantages over pulse thermography (PT) in minimizing temperature fluctuations and providing higher contrast and less noise in phase images. However, PT was better at showing the upper paint layer, which is important for observing subsurface defects or the support structure. The influence of camera spectral range on the results was also investigated, with the addition of a long-pass filter eliminating direct reflection artifacts caused by halogen light sources when using a mid-wave infrared (MWIR) camera.

Summary: This study examines the chromatic alteration of various paint types on mural painting fragments from The Upper Basilica of Saint Francis of Assisi in Italy using synchrotron radiation. The fragments are from ceiling paintings attributed to Cimabue and Giotto, with different discoloration in white, blue/green, and brown/yellow/orange areas. X-ray fluorescence and diffraction maps were collected from the fragments, and paint cross-sections were analyzed using microscopic X-ray fluorescence and powder diffraction mapping. The study identified numerous secondary products on the painted surfaces, including copper tri-hydroxychloride, corderoite, calomel, plattnerite, scrutinyite, whewellite, and weddellite.

Summary: The study of ancient Egyptian paintings started in the 19th century with the development of Egyptology. By the 1930s, extensive research had been conducted on the materials and techniques used. However, most of these studies were done in museums, with limited understanding of the actual painted surfaces. To address this gap, an interdisciplinary project employed portable analysis tools to study the physical composition of the paintings on-site, providing a stronger foundation for scientific hypotheses and a deeper understanding of ancient Egyptian art.

Summary: This paper presents the spatio-temporal dynamics of a Grimm-type microsecond pulsed glow discharge (mu PGD) in argon at 6 mbar. The occurrence of a high current peak during the discharge ignition is analyzed and the importance of displacement current is emphasized. The development of electron excitation temperature for argon atoms and ions at various distances from the cathode is measured. The spatio-temporal evolution of selected spectral lines of argon and copper atoms and ions is analyzed during different phases of the discharge. The results suggest that the behavior of spectral line emissions differs between the pre-peak and afterglow periods, with different lines reaching maximum intensity during these phases. The appearance time and decay time of the afterpeak are shorter for ions than for atoms. These findings are explained in terms of three-body recombination processes and ion mobilities.

Summary: In this paper, the combination of Tesla coil discharge (TCD) and laser-induced breakdown spectroscopy (LIBS) was used to enhance the emission of Al atomic lines and AlO molecular bands. The optimized distance between the TCD tip and the sample surface was found to be 5 mm, and the optimal laser energy was 25.1 mJ. Furthermore, TCD-SELIBS showed lower limits of detection (LoDs) for Cr and Pb elements compared to surface enhanced LIBS (SELIBS). The combination of TCD and LIBS is a promising technology for high-sensitivity analysis of heavy metals in water, with the advantages of simplicity, low cost, ease of operation, industrialization, and commercialization.

Summary: Titanium is an important metal widely used in various industries. Ilmenite minerals are the main source of titanium metal and can be found in igneous and metamorphic rocks as well as different types of deposits. To accurately determine U-Pb ages of ilmenite, a new calibration method and appropriate reference materials are urgently needed. Laser ablation sector field inductively coupled plasma mass spectrometry has been used to minimize matrix effects and zircon 91500 has been identified as a suitable reference material for measuring the Pb/U ratio in ilmenite. The direct calibration method using zircon 91500 as an external standard has been found to be effective for in situ U-Pb dating of ilmenite samples under different ablation settings.
