By conducting a combination of experiments and Multiphysics finite element simulations, a comprehensive comparison was made regarding the properties exhibited by three polyimide (PI) composites: PI/sea urchin-like HAP, PI/spherical HAP, and PI/rodlike HAP. The incorporation of high-surface-area spherical HAP or high aspect ratio rodlike HAP introduces intricate and convoluted growth paths for electric tree formation within the PI matrix, thereby augmenting the energy storage density (U_e) at elevated temperatures (U_{η > 90%} = 4.82 J/cm³, U_{η > 80%} = 6.11 J/cm³, U_{η > 70%} = 8.73 J/cm³, at 150 ℃).

This method is widely anticipated by researchers due to its potential to enhance photon utilization efficiency at the reaction source. However, limited attention has been devoted to the variations in photothermal conversion performance of particle reaction suspensions caused by objective fluctuations of solar irradiation, especially when the morphology of the nanostructure changes, which is a crucial factor for practical applications in hydrogen production. Based on this bottleneck, we prepared the typical photo-responsive TiO₂@Go composite with varied dimensions (i.e., nanosphere TiO₂@Go, nanorod TiO₂@Go, nanosheet TiO₂@Go) as research models, and systematically investigated their thermal conversion and sensible heat conversion performance under different working conditions. The results showed that at low nanofluid concentration, nanosphere TiO₂@Go and nanosheet TiO₂@Go exhibit better sensible heat conversion. As the particle concentration increases, the sensible heat conversion efficiency of all nanofluids decreases. It can also be found that the latent heat conversion efficiency tends to increase with the increase of concentration, but the nanorod TiO₂@Go show the opposite, which should be closely related to the uniformity of the particle size in different directions. In addition, for the sensible heat storage properties of nanofluids, smaller particle size and abundant porosity due to particles aggregation were found to be more beneficial for varied shapes. The underlying functional mechanisms were elucidated associated with the analysis of particle structures, interfacial properties, and optical characteristics.

Gemcitabine, a cytosine nucleoside analog, is widely used for various solid tumors; however, its effectiveness is often limited by drug resistance and adverse side effects. In this study, we developed a novel drug delivery system, Mn/Se-Gem, designed to target tumor cells overexpressing CD44 and facilitate the controlled release of gemcitabine. This system exploits gemcitabine's pH sensitivity and HA-mediated CD44 targeting to induce DNA damage. Simultaneously, it neutralizes the acidic tumor microenvironment and releases nano-selenium and manganese ions, which promote the excessive production of reactive oxygen species (ROS), leading to mitochondrial damage and enhanced apoptosis of cancer cells. Furthermore, Mn (II) activates the cGAS-STING pathway, increasing susceptibility to ROS-induced DNA double-strand breaks, promoting macrophage maturation, inhibiting M2 polarization, and enhancing the cytotoxic function of T lymphocytes against tumor cells.
