Summary: Experimental evidence of 3D chiral spin textures, including helical spins and skyrmions with different chirality and topological charge, has been reported in amorphous Fe-Ge thick films. These results demonstrate that structurally and chemically disordered materials can resemble inversion symmetry broken systems with similar magnetic properties, moments, and states, providing greater flexibility in materials synthesis, voltage, and strain manipulation.

Summary: The blend of PLA/FG with the presence of DCP through melt extrusion process shows potential for producing films with tailored characteristics, improved interfacial interaction, increased toughness, UV-C blocking effect, and hydrophobicity. The study also confirmed the grafting of PLA chains on FG through formation of new C-C linkage, and POM studies revealed higher crystal density in PLA/1FG compared to PLA at 120 degrees C. This melt extrusion process has great potential for developing bionanocomposite films and overcoming specific drawbacks of FG with the assistance of DCP.

Summary: It has been found that doping Sr into CsPbX3 perovskites can improve the photoresponse performance and reduce the Pb content for environmental protection. By investigating the effects of Sr doping concentration, it was found that Sr doping increased the density of CsPbBr3 thick films and modulated their bandgap. CsPb1-xSrxBr3 exhibited good optical responses under different bias voltages and X-ray doses. The X-ray response improved with increasing Sr doping concentration. Therefore, partially substituting Sr into CsPbBr3 is a feasible method for reducing Pb content in X-ray detectors. Furthermore, the development of CsPb1-xSrxBr3 thick films provides a new strategy for X-ray detection.

Summary: The formation of crystal phases in Li2O-Nb2O5 compound films deposited on sapphire substrates were studied by X-ray diffraction. Different crystallization behaviors were observed for films on C-plane and A-plane substrates, and the presence of Li-deficient or stoichiometric compositions influenced the crystallization process. The use of an amorphous LN buffer layer followed by solid-phase crystallization allowed for the growth of crack-free thick LN epitaxial films on a sapphire C-plane.

Summary: The microstructure at the interface between the cocatalyst and semiconductor is crucial for the concentration of photo-induced carriers and reactants. Recent research has observed the transformation of Ti-6c-O bonds into Ti-5c-O and Ti-6c-O-Pt bonds on the TiO2-010 facet, affecting the selectivity of resulting products. These findings provide valuable insights for the development of new methodologies using conventional lab-grade equipment.

Summary: A homogeneous bridging strategy was developed to directly prepare compact perovskite films. A stable perovskite slurry with suitable viscosity was formed by adding a weak coordination solvent to pre-synthesized microcrystalline powders. In situ growth of small perovskite grains filled the pinholes and connected the surrounding original grains, resulting in a large-area perovskite thick film with tight grain arrangement and ultralow current drift for X-ray imaging.

Summary: The study focuses on optimizing the deposition design of coextruded continuous carbon fiber composite filament with PETG filament, finding that the highest mechanical properties were obtained at a raster orientation of 0 degrees for both reinforced and non-reinforced materials. Additionally, the presence of shells improved the tensile strength of non-reinforced PETG, while the mechanical behavior of printed specimens depended on the anisotropy of porosity.

Summary: X-ray micro-computed tomography (X-ray mu-CT) is a non-destructive method for visualizing the internal microstructures of materials in 3D. It has been used in the field of food science to study the microstructures of different food materials. Small-angle X-ray scattering (SAXS) is another non-destructive method used for analyzing the structure of materials at the micro or nano level. This review discusses the applications and limitations of X-ray mu-CT and SAXS techniques in food systems.
