Abstract Metamorphic fluids, faults, and shear zones are carriers of carbon from the deep Earth to shallower reservoirs. Some these fluids reduced transport energy sources, like H 2 light hydrocarbons. Mechanisms pathways capable transporting sources towards reservoirs remain unidentified. Here we present geological evidence failure mechanically strong rocks due accumulation CH 4 -H -rich at forearc depths, which ultimately reached supralithostatic pore fluid pressure. These originated...
Polymeric materials made from renewable sources that can biodegrade in the environment are attracting considerable attention as substitutes for petroleum-based polymers many fields, including additive manufacturing and, particular, Fused Deposition Modelling (FDM). Among others, poly(hydroxyalkanoates) (PHAs) hold significant potential candidates FDM since they meet sustainability and biodegradability standards mentioned above. However, most utilised PHA, consisting of poly(hydroxybutyrate)...
Abstract X‐ray microscopy (XRM) is a non‐destructive characterization technique that provides quantitative information regarding the morphology/composition of specimen and allows to perform multiscale multimodal 2D/3D experiments exploiting radiation‐matter interactions. XRM particularly suitable afford in situ images inner parts battery for early diagnosis its degradation non‐invasive way. Since traditional techniques (SEM, AFM, XRD) often require removal component from encapsulated device...
Carbon-phenolic ablators can efficiently protect space vehicles from the extreme temperatures typical of reentry phase in a planet's atmosphere. Their performances are attributed to low thermal conductivity and decomposition phenolic resin. These phenomena strongly influenced by materials microstructure. In present work, standard polyvinylpyrrolidone (PVP)-modified carbon-phenolic were manufactured characterized: influence PVP on final microstructure chemistry was studied through SEM-EDS,...

Traditional techniques provide effective means identify the chemistry and mineralogy of products. Nevertheless, a further step necessary upgrade understanding evolution three dimensions. In this regard, Multiscale X-ray Microscopy (XRM) enables multi-length scale visualization whole object provides spatial distribution phases. Herein, we propose an integrated...
Abstract 3D imaging is a powerful tool of high resolution and non-destructive technology for the study ancient weapons military technology, which reveals original microstructures corrosion patterns that threaten these artefacts. Here we report quantitative analysis distribution orientation fractures, uncorroded metal particles within wrought iron javelin unearthed at Phoenician-Punic site Motya, Italy. The aimed to gain better understanding relationship between local stresses artifact...

Managing the worldwide steady increase in production of plastic while mitigating Earth's global pollution is one greatest challenges nowadays. Fungi are often involved biodegradation processes thanks to their ability penetrate into substrates and release powerful catabolic exoenzymes. However, studying interaction between fungi challenging due deep hyphal penetration, which hinders visualisation evaluation fungal activity. In this study, a multiscale multimodal correlative microscopy...
Correlative light and electron microscopy (CLEM) is an advanced imaging approach that faces critical challenges in the analysis of both materials biological specimens. CLEM integrates strengths microscopy, a hardware software correlative environment, to produce composite image combines high resolution microscope with large field view microscope. It enables more comprehensive understanding sample’s microstructure, texture, morphology, elemental distribution, thereby facilitating...
In this work, we employed correlative imaging techniques to investigate the complex corrosion systems in nails from Phoenician-Punic site of Motya (Sicily, Italy), combining analytical chemistry and tomography across multiple dimensions scales. To accomplish this, used light electron microscopy, micro-Raman spectroscopy, X-ray microscopy. The results showed remarkable differences condition nails, with one nail well-preserved thinly coated oxyhydroxides, while other exhibited extensive...
The diffusion of pollutants in the marine environment is nowadays a well-recognized issue that attracting growing interest from scientific and social communities. One possible strategies to study effect quantify their presence inside organisms are directly exposed for certain period polluted environment. Among them, mussels, commonly considered as “biological water filters”, stand out ideal candidates since they stationary animals food intake comes only filtering surrounding water. Thus,...
Abstract In recent years, there has been a growing interest in the use of additive manufacturing (AM) to fabricate metallic components with tailored microstructures and improved mechanical properties. One most promising techniques for aerospace industry is powder bed fusion-laser beam (PBF-LB). This technique enables creation complex shapes structures high accuracy repeatability, which especially important where require precision reliability. However, impact PBF-LB process on microstructural...

The reconstruction of infant biological history and mortality profiles provides biocultural insights into adulthood morbidity, maternal health, parental caregiving practices, social dynamics. However, interpreting data from cremated remains in archaeological contexts can be challenging due to their often poor preservation potential biases. Tophets, sanctuaries for distinct burial present several Phoenician-Punic colonies the Mediterranean area, offer an ideal case study. This study presents...
Abstract Image segmentation is a valuable tool for visual image data inspection of semiconductor device structures. For the large amounts provided by recent advancements in automated scanning electron microscope (SEM) and focused ion beam-scanning (FIB-SEM) acquisition, automatic becomes indispensable to fully exploit information contained characterization workflows. Using two exemplary FIB-SEM tomography datasets, we explored artificial intelligence based using only minimum amount training...
