Summary: The remineralizing potential of hydroxyapatite has led to its use in dental composites. However, the compatibility between hydroxyapatite and organic compounds is insufficient, resulting in low mechanical properties. Polyhedral oligomeric silsesquioxanes show promise as additives to dental composites, and their modification of hydroxyapatite surfaces improves mechanical properties and reduces water sensitivity.

Summary: A unique 3D interconnected Si/SiOx/C nanorings were successfully fabricated via AlCl3-assisted aluminothermic reduction, showing great potential in the field of lithium ion batteries. The obtained nanorings exhibited uniform diameter and well distribution of C and Si elements, along with superior high-rate capacity and good cycle stability as an anode for LIBs. Furthermore, they delivered high reversible capacity at ultra-low temperature, broadening the application possibilities of POSS.

Summary: This study investigates the improvement of lubricating coatings by covalently grafting octa-amino polyhedral oligomeric silsesquioxane (POSS) onto polyimide (PI) matrix. The results show that the addition of POSS enhances the tensile strength, nano-hardness, and wear resistance of the coatings without affecting the breaking elongation. This improvement can be attributed to the increased cohesion strength and load-bearing capacity of the composite coatings reinforced by POSS.

Summary: By introducing methacryl polyhedral oligomeric silsesquioxane (Ma-POSS), the holographic performance of phenanthraquinone-doped poly(methyl of high sensitivity, high diffraction efficiency, and neglectable volume shrinkage for holographic data storage has been dramatically enhanced. Ma-POSS significantly increases the photosensitivity by 5.5 times and improves diffraction efficiency by more than 50%, while suppressing volume shrinkage over 4 times. The molecular weight is increased by grafting PMMA to be a star-shaped macromolecule, and the residual C=C of POSS-PMMA enhances the photosensitivity. The addition of star-shaped POSS-PMMA as a plasticizer further enhances the mechanical properties and reduces photoinduced volume shrinkage.

Summary: By introducing eight methacryl polyhedral oligomeric silsesquioxane (Ma-POSS), the holographic performance of phenanthraquinone-doped poly(methyl methacrylate) (PQ/PMMA) is dramatically enhanced, with high sensitivity, high diffraction efficiency, and neglectable volume shrinkage. Ma-POSS increases the photosensitivity, diffraction efficiency, and suppresses volume shrinkage. The molecular weight of PQ/PMMA is increased by grafting PMMA into star-shaped macromolecules. The residual C=C of POSS-PMMA significantly enhances the photosensitivity and the star-shaped POSS-PMMA acts as plasticizer to improve the mechanical properties and reduce the photoinduced volume shrinkage.
