ANTIMICROBIAL SOLUTIONS FOR BIOMATERIALS AND SURFACES

Biofilm formation on implant surfaces is the primary pathogenic mechanism, protecting bacteria from host defenses and antibiotics. Conventional approaches such as antibiotic-loaded cements, spacers, and beads can deliver high local drug concentrations but are limited by poor release control, inadequate biofilm penetration, and lack of biodegradability, underscoring the need for improved strategies. Recent advances in biomaterials research provide promising alternatives, including multifunctional biomimetic materials, bioresorbable metal alloys, and nanocomposites capable of controlled antimicrobial ion release. Coated Mg- or Zn-based alloys combine antibacterial activity with gradual degradation and suitable mechanical properties, while biomimetic scaffolds and antibacterial calcium phosphate coatings can both reduce bacterial adhesion and support osteogenesis and vascularization. Overall, multifunctional biomaterials that integrate infection control with tissue regeneration and significantly improve long-term implant success.

ENHANCED RADIATION SHIELDING IN SPS-PROCESSED B₄C CERAMICS THROUGH HIGH-ENTROPY ALLOY ADDITIONS

Boron carbide (B₄C) is one of the most critical structural ceramics for extreme environments, combining exceptional hardness, low density, chemical stability, and strong neutron absorption capability. These attributes make B₄C highly attractive for lightweight armor and nuclear shielding applications; however, insufficient densification and intrinsically low fracture toughness continue to limit its broader structural utilization. This talk presents an approach to overcome these limitations through the incorporation of an equiatomic FeNiCoCrMo high-entropy alloy (HEA) as a multifunctional sintering aid for B₄C, followed by consolidation via spark plasma sintering. Various microstructural, phase, and mechanical characterization techniques were employed, and neutron shielding performance was evaluated experimentally at the ITU TRIGA Mark-II reactor using a Pu–Be source. In addition, Monte Carlo simulations (Geant4) based on experimentally determined densities and geometries are discussed to further elucidate radiation attenuation behavior. The results demonstrate that HEA incorporation significantly improves densification, mechanical integrity, and neutron attenuation efficiency, revealing a synergistic pathway that integrates compositional complexity, advanced sintering, and physics-based modeling. Overall, this talk highlights HEA-assisted B₄C ceramics as a promising platform for next-generation lightweight radiation-shielding systems relevant to nuclear energy and defense technologies.

ELUCIDATING THE DYNAMIC MOLECULAR INTERACTIONS OF METAL-ORGANIC FRAMEWORKS (MOFs)-REINFORCED POLYMER NANOCOMPOSITES

The demand for polymer-based nanocomposite-reinforced nanoporous materials is becoming increasingly important in sustainable development studies. Integrating nanoporous materials such as metal–organic frameworks (MOFs) into polymer matrices is essential for the development of sustainable advanced materials. Combining MOFs with polymer matrices can produce hybrid materials with improved mechanical strength and stability compared to their individual constituents. This study aims to elucidate the effect of synthesised UiO-66 nanoparticles incorporated into a polyurethane (PU) matrix on the resulting hybrid materials’ microstructural mechanical properties and adsorption properties. UiO-66 nanoparticles were synthesised at 120 °C, 130 °C, and 140 °C. The nanoparticles and the resulting nanocomposites were characterised using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Brunauer–Emmett–Teller (BET) analysis, and field emission scanning electron microscopy (FE-SEM). The experimental findings indicate that UiO-66 nanoparticles synthesised at 130 °C exhibited a highly desirable crystal structure and effective adsorption properties; therefore, nanoparticles synthesised at this temperature were selected to reinforce PU, forming a polymer–MOF nanocomposite. The mechanical properties of the resulting nanocomposites were evaluated using tensile and nanoindentation tests. UiO-66 nanoparticles were incorporated into the PU matrix at various weight percentages (10 wt.%, 20 wt.%, 30 wt.%, and 40 wt.%) via the solution casting technique. The results indicate that the polymer nanocomposite containing 30 wt.% UiO-66 exhibited the best mechanical performance, while loadings beyond 30 wt.% were more likely to result in nanoparticle agglomeration and brittle behaviour. The intricate interplay between MOF fillers and polymer matrices governs the structure-property relationship of the resulting polymer nanocomposites, which is crucial for tailored material design. Investigating the iodine capture analysis and dye removal capabilities of PU/MOFs, UiO-66/PU emerges as the top-performing nanocomposite. This enhancement is attributed to the unique properties of UiO-66 MOF and its well-distributed pore sizes. Adsorption mechanisms, driven by Van der Waals forces, π-π interactions, and hydrogen bonds, facilitate the binding of iodine and dyes to the nanocomposite surface. This research signifies a step toward environmentally sustainable material synthesis using MOFs, offering potential applications in energy storage and contributing to improved environmental conditions. Furthermore, it lays the groundwork for resilient rubbery-MOF nanocomposite systems suitable for real-world applications.
