Summary: In this study, ABS composites filled with graphite powder were synthesized using FDM technique. The addition of graphite resulted in weight losses for FDM components and a decrease in coefficient of friction. The wear mechanisms in graphite filled ABS composites and ABS were extensively examined using microscopy techniques.

Summary: The microstructure of fired clay bricks made of five different Central European raw materials was investigated using Scanning Electron Microscopy, Energy Dispersive X-ray Spectroscopy, and Powder X-ray Diffraction. An automated process for characterizing and quantifying material phases in brick microstructures was developed based on extensive experimental data, revealing a large variety of microstructures in European brick materials. The collected data allows for a deep understanding of these materials and provides a reliable basis for the development and optimization of fired clay bricks using micromechanical models.

Summary: This study investigates the impact of trace impurities on the nodularity of spheroidal graphite cast irons during manufacturing, revealing the presence of impurities at the interface between the spheroid and protrusion alongside magnesium. Using Focused Ion Beam and atomic resolution scanning-transmission electron microscopy, it is shown that impurities can disrupt the spheroidizing effect of magnesium without a definite crystallographic relationship between protrusions and underlying spheroids.

Summary: Transport properties of hydrogel samples are modified by adding amphiphiles, such as lecithin, which affects their potential as drug carriers. Various probes are used to simulate drugs in diffusion experiments, controlled by UV-Vis spectrophotometry, and scanning electron microscopy is used to characterize the diffusion systems. The results indicate that lecithin can alter the structure of hydrogels and therefore affect their transport properties.

Summary: The early metabolic modifications in bacteria following induced stress were evaluated using a new method combining energy-dispersive X-ray microanalysis and scanning electron microscopy. Different preparation methods were investigated to detect alterations in the bacterial chemical composition. The results showed that the method could provide early predictions of bacterial viability state in different conditions, yielding earlier results than culture.

Summary: This study investigated the decomposition process of the isothermal alpha '' phase in beta-Ti alloys, and found that the resulting alpha + beta dual phase inherited the microstructural characteristics of the alpha ''(iso) phase. The research results indicate the existence of a strict variant selection rule between the decomposed alpha and beta phases, with a specific variant combination observed.

Summary: This article proposes a new method for serial section registration using an unsupervised optical flow network to measure feature similarity and eliminate nonlinear deformation. The optical flow network is also used to estimate and compensate for cumulative registration error, enabling the reconstruction of biological tissue structures. Experimental results demonstrate that this method effectively improves the spatial continuity of serial sections and enhances the accuracy of registration and reconstruction for biological tissue structures.

Summary: This article reports the exploration of the chemical versatility of entropy-stabilized pyrochlores (A(2)B(2)O(7)) with large chemical disorder introduced on the B site. It also investigates the effects of isovalent and aliovalent substitution on the B site and Ca2+-doping on the A site. The study obtained 20 new compounds, including 8 entropy-stabilized ones, and screened their physical properties for potential applications.

Summary: This paper proposes a preprocessing method for uneven-surface EDS maps to enhance the efficiency of the pansharpening process. The optimal order of preprocessing steps is background removal, noise filtering, and interpolation. The best performing pansharpening methodology is Affinity for individual map analysis and Wavelet for multi-elemental fusion purposes. High-resolution EDS maps are achieved for uneven-surface particles for the first time.

Summary: In X-ray spectroscopic studies, K beta 1,3 lines have been used to examine the chemical states of 3d transition metals, but are not suitable for characterizing iron oxides. Instead, FeL-lines, which involve the valence shell 3d electrons, were inspected and found to provide information on the chemical states of iron. The study established a linear relationship between the chemical shift of FeL beta 1 line and spin multiplicity, allowing for the speciation of iron.
