Summary: Silicon-containing arylacetylene resins synthesized with interchain pi-pi stacking interactions show higher mechanical properties and heat resistance compared to traditional resins. The strong interchain pi-pi stacking interactions in the PODSA resins result in higher melting temperature and thermal conductivity post-curing.

Summary: Porous Hap-Gel composite microspheres synthesized by wet chemical methods were used as carriers for DOX, and the addition of chitosan increased the drug entrapment efficiency and prolonged the release duration. The protection of pores in the microspheres allowed chitosan to effectively combine with HAp-Gel and DOX, enhancing the drug's therapeutic function.

Summary: By optimizing the loading strategy, proteins can be efficiently loaded into porous silicon nanoparticles (PSiNPs), forming nanocomposites with ultrahigh loading and high activity. These nanocomposites have colloidal stability under cryopreservation, endosome escape ability, and gene editing efficiencies twice that of the commercial standard Lipofectamine CRISPRMAX. In various animal models, PSiNPs can edit cells in different tissues and achieve significant reduction in gene expression, demonstrating their versatility and potential for both local and systemic gene editing applications.

Summary: This study investigates the degradation pattern of magnesium (Mg) alloys used as bone substitutes. It found that in situ cyclic compression accelerated the corrosion rate, but no critical failures in mechanical integrity were observed. The accumulation of corrosion products led to structural changes and changes in mechanical properties.

Summary: This study used PECVD to deposit a silicon nitride layer on multicrystalline silicon with and without porous silicon, aiming to enhance its properties for solar cell applications. The results showed that the application of silicon nitride reduced reflectance and improved the carrier lifetime and minority carrier diffusion length. Combining porous silicon with a SiNx thin film further improved the performance.

Summary: Dual-state emissive fluorogens play an important role in biological and biomedical applications. This study successfully designed and synthesized solid-state emitting twisted pi-conjugates to achieve specific anticancer dual-state emissive fluorogens. These molecules can detect and distinguish cancer cells from normal cells using bioimaging, and exhibit decent anticancer properties against certain cancer cell lines.

Summary: The paper introduces a multifunctional nano drug delivery system inspired by a PLA-TPGS copolymer, co-loaded with Doxorubicin and magnetic iron oxide nanoparticles. The drug release kinetics of Doxorubicin from this system fits best to the Weibull kinetic model and shows good cell penetration with maintained fluorescence properties. Various cell cycle profiles were observed in HeLa cell lines treated with the MNDDS.

Summary: New fluconazole-loaded hydrogels incorporating nanohydroxyapatite were prepared and characterized using XRD, SEM-EDS, and ATR-FTIR. The antifungal activity of fluconazole was tested against various Candida, Cryptococcus, and Rhodotorula species. The hydrogels were found to be excellent drug carriers and effective in preventing fungal infections in chronic wounds.
