Summary: Bioactive glasses incorporating metallic ions, such as Cu-45S5, have promising applications in bone tissue engineering due to their antibacterial activity and ability to stimulate osteogenesis and angiogenesis. This study investigated the structural changes of Cu-doped 45S5 BG during sintering, revealing the formation of combeite and rhenanite crystalline phases, as well as the presence of a residual glassy phase enriched with Na and P ions. The crystallinity and crystal size of Cu-45S5 glass-ceramics can be adjusted through appropriate heat treatment, with Cu localized in the residual glassy phase affecting the release of Cu ions in physiological environments.

Summary: In recent years, researchers have extensively studied multifunctional inorganic-organic hybrid materials to determine their potential effects on reactivity. This study designed and characterized a hybrid material by combining photocatalytic TiO2 nanoparticles with sodium surfactin (SS), a biosurfactant with high affinity for metal cations and antimicrobial properties. The synthesis methodologies and different TiO2:SS weight ratios were investigated to understand their effects on colloidal, physicochemical, and functional properties. The breaking point between TiO2 and SS single-component trends was identified and different ranges of applicability were determined. At low SS contents, the hybrid material showed preserved photocatalytic properties and additional antimicrobial effects, while at high SS contents, TiO2 photoactivity was inhibited and the hybrid material could be used as a UV blocker. Around the breaking point, the hybrid material exhibited high surface area, NOx depletion, and improved adhesion for antibacterial coatings, making it suitable for water/soil remediation applications.

Summary: PMMA-based composite bone cements with bioactive and ferrimagnetic glass-ceramic particles have been prepared and characterized. The study investigated their bioactivity, wettability, density, curing parameters, viscoelastic behavior, bending strengths, and creep at 37 degrees C. The presence of glass-ceramic particles improved the wetting behavior of the composite cements. The mechanical properties of the composite bone cements were almost unaffected compared to that of plain commercial cement, and radiographic imaging confirmed their radiopacity.

Summary: In this study, bioactive and antibacterial glass was added to a commercial PMMA-based bone cement to improve bone-cement integration and reduce bacterial contamination. The impact of the amount and size of glass powders on the mechanical properties, radio-opacity, bioactivity, and antibacterial effect of the composite cements was evaluated. The results showed that both the amount and size of the filler influenced the bending strength of the samples. The radio-opacity of the composites could be adjusted by varying the amounts of glass and radio-opaque agent. Introduction of 10 wt.% glass conferred bioactive behavior to the PMMA-based matrix and limited bacterial contamination. A proposed approach for technological transfer with controlled process parameters was also presented.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.
