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.

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: Biomass-based polymers have attracted significant attention due to their ability to be regulated using functional materials. This study focused on the synthesis of nonisocyanate polyurethane (NIPU) using ricinoleic acid-derived cyclic carbonate and aliphatic diamine, with the incorporation of octa(aminopropyl) polyhedral oligomeric silsesquioxane (OAP-POSS) as a poly-amine for introducing POSS units and regulating the properties of the material. The curing process was monitored using Fourier transform infrared spectroscopy, and it was found that a curing time of 12 hours at 50 degrees Celsius was sufficient for polymerization. Different NIPUs modified with various molar fractions of OAP-POSS were obtained, and the material with 100% substitution of OAP-POSS for diamine showed the highest thermal stability, shore hardness, and water resistance.

Summary: Pt/C and SO42-/ZrO2 were used as catalysts for the synthesis of p-aminophenol through the catalytic transfer hydrogenation of nitrobenzene in water with formic acid as the hydrogen source. The optimal Pt loading for PAP selectivity was found to be 1 wt%. The presence of different valence states of Pt affected both the nitrobenzene hydrogenation and formic acid decomposition. Among different solid acid catalysts tested, SO42-/ZrO2 exhibited the highest catalytic activity for p-aminophenol formation. Under the optimized reaction conditions, the conversion of nitrobenzene reached 80.0%, with a selectivity of 47.6% for p-aminophenol.

Summary: The mechanism of the reaction between CO2 and styrene oxide for cyclic carbonate was revealed using density functional theory calculations. The noncatalytic reaction occurred via a concerted mechanism, while in the presence of guanidine and tetrabutylammonium iodide (TBAI) co-catalysts, the epoxide ring-opening by nucleophilic attack of an iodide anion was predicted to be the rate-determining step. Guanidine acted as the H-bond donor to activate styrene oxide, facilitating the reaction with a lower activation barrier.

Summary: Copper nanorods (Cu-NRs) exhibit significant plasmonic behavior and can act as efficient catalysts in redox processes and coupling. A benign decarboxylative approach, utilizing localized surface plasmon resonance (LSPR) assisted catalysis with Cu-NRs, has been developed for the production of alkane analogues from alkyl carboxylic acids under visible light. The catalyst shows a broad substrate scope and high functional group tolerance, without the need for an external oxidant or proton source. A plausible mechanism for this recyclable nano-catalyst has also been proposed based on control experiments.
