The emergence of highly resistant bacterial strains poses a major threat to patients, driven by extensive global use of antibiotics. In pulmonary infections, antibiotics are widely used, making bacterial resistance a serious risk. Cathelicidins (CATH) are antimicrobial peptides of the innate immune system in various organisms, including humans. CATHs act by interacting with negatively charged...
The main objective of this work is to analyze the structural properties of cobalt ferrite magnetic nanoparticles using the Small-Angle Neutron Scattering (SANS) technique, which involves neutron scattering at small angles, and to subsequently model and fit the experimental data. A key part of the research was carried out in September 2025 at the Institut Laue–Langevin (ILL) research center in...
Reliable extraction of microstructural information from X-ray diffraction (XRD) data requires accurate separation of instrumental broadening from the intrinsic sample response. In this work, we present an iterative forward-convolution method optimized using a genetic algorithm (GA) to recover intrinsic diffraction line profiles from measurements acquired in transmission geometry with a...
Fe-based amorphous ribbons can acquire tailored magnetic anisotropy when crystallization occurs under applied tensile stress. However, the accompanying structural evolution and its relationship to stress-induced anisotropy are not yet fully understood. Here, the crystallization behaviour of VITROPERM 800 was investigated in real time using high-energy synchrotron X-ray diffraction. Amorphous...
X-ray diffraction computed tomography (XRD-CT) combines the structural sensitivity of diffraction measurements with the spatial resolution of tomography, enabling the non-destructive mapping of crystalline phases and microstructural properties within heterogeneous materials. This talk will provide an overview of XRD-CT methodology and its implementation at the I12-JEEP beamline, with emphasis...
