In this work, CS/PVA membranes and nanofibers were synthesized and characterized to evaluate their blood biocompatibility. We used Fourier transform infrared spectroscopy (FTIR), atomic force microscopy (AFM), and scanning electron microscopy (SEM) to characterize the materials. The biocompatibility of the CS/PVA nanostructures was determined by the percentage of hemolysis, blood morphology by the Wright stain and apoptosis by the acridine orange/propidium iodide (AO/PI) stain. The results showed an interaction between CS and PVA in the membranes and in the nanofibers. When used as filters, the CS/PVA membrane changes and this change is drastic in CS/PVA nanofibers.

In addition to optimizing 3D printing orientation, this study uses Response Surface Methodology (RSM) and optimization algorithms to optimize design parameters such as safety factor and thickness for predicting stress and deformation in topology optimization. The results show that RSM, Artificial Neural Network (ANN) and observed simulation results strongly correlate, confirming their reliability for determining the most optimal design parameters for topology optimization.

These results were verified using optimization software, confirming the effectiveness of the study's methodology. Vertical orientation is the optimal printing orientation to develop parts with greater hardness, according to X-ray Diffraction (XRD), hardness, wear resistance, and morphological tests. Testing confirmed that the topology-optimized result, which utilized the most optimal process condition and orientation, effectively produced a stronger 3D-printed part.

Graphite samples were irradiated with hydrogen ions at incremental fluences (1, 10, 20 shots). Surface modifications (voids, cracks, melting) were analyzed using optical microscopy (OM) and scanning electron microscopy (SEM). The resulting surface changes were clearly visible in the SEM and OM images. Microscopic analysis of the samples subjected to gradual irradiation and point sputtering revealed voids and localized melting on the sample surfaces, which were correlated with increasing ion fluence, particularly after 20 shots. Structural changes in the graphite caused by high-energy proton irradiation were quantified via X-ray diffraction (XRD). The XRD spectrum of the irradiated samples exhibited shifts in peak positions and recrystallization (crystal growth) due to transient thermal annealing, indicating significant structural alterations. To characterize the hydrogen ions produced by the plasma focus device, the Lee code and a Faraday cup detector were utilized. The experimental results showed that the average ion energy was approximately 46 keV. Ion penetration depth, hydrogen retention, and radiation damage were simulated using the SRIM code. The simulation results indicated that the maximum damage occurred at a depth of 200 nm, with a damage rate of 0.024 displacements per atom (dpa) per shot. The highest concentration of hydrogen ions, measured at 0.6 %, was found at a depth of 220 nm.

A critical challenge, however, is the crucible's performance in the highly corrosive environment of aggressive melts and reducing gases. To address this, two protective measurements for a magnesium-oxide (MgO) crucible were investigated: one involved applying a thin graphite coating to minimize lithium diffusion, while the other utilized varying sizes of graphite cubes to create a protective temperature gradient. In addition, this study included the simulation of temperature distribution within the crucible using the OpenFOAM multi-region framework as a reason for the high impact of temperature on several different chemical and physical phenomena within the recycling process. Experimental findings show minimal lithium diffusion and corrosion in the graphite-coated crucible, with transfer coefficients above 90 % for all elements and up to 99 % for lithium. As revealed by Micro XRF cross-sectional analysis, the crucible with varying susceptor material sizes showed no contact between the input material and the refractory. This configuration can effectively act as a thermal and physical shield, providing an optimal barrier that prevents corrosion and diffusion effects at the crucible wall.
