Article Synopsis
- The study investigates the dielectric properties and photocatalytic behavior of cobalt-doped P25 Degussa powder, focusing on various cobalt concentrations.
- Cobalt doping was achieved using a specific precursor, and the research identified a critical concentration limit beyond which metallic clusters form, affecting the uniformity of cobalt distribution in the titanium oxide matrix.
- Additionally, the findings indicate ongoing relaxation processes at temperatures below 400 °C, and reveal that certain electronic states exist within the energy gap of titanium oxide across all nanopowder samples, influencing their photocatalytic performance.
Article Synopsis
- CaTiO is identified as a potential scaffold material for bone implantation, with improved pseudo-piezoelectric properties when doped with magnesium and iron.
- The study employed sol-gel synthesis and spark plasma sintering to create both pure and doped CaTiO, revealing that doping enhances structural strain and defects, leading to a stronger pseudo-piezoelectric effect.
- Magnesium doped CaTiO produced a charge of (2.9 ± 0.1) pC, while iron doping resulted in the highest charge of (3.6 ± 0.2) pC, indicating that doping can be used to optimize piezoelectric responses for better bone tissue engineering applications.
Vitrification is the most effective method for the immobilization of hazardous waste by incorporating toxic elements into a glass structure. Iron phosphate glasses are presently being considered as matrices for the storage of radioactive waste, even of those which cannot be vitrified using conventional borosilicate waste glass. In this study, a structural model of 60P2O5-40Fe2O3 glass is proposed.

The titanium-manganese (TiMn) alloys have been extensively used in aerospace and hydrogen storage. In this study, the TiMn alloys with various manganese contents ranging from 2 to 12 wt % were prepared by using mechanical alloying and spark plasma sintering (SPS) techniques. The microstructures, mechanical properties including hardness, elastic modulus and ductility, cytotoxicity and cell proliferation properties of the TiMn alloys were investigated to explore their biomedical applications.
