NiFe₂O₄, characterised by a mesoporous spinel structure, was successfully synthesised from electroplating sludge by a single-step heat treatment. The catalyst was uniformly distributed with SiO₂ glass beads throughout the plasma discharge area, enabling an efficient transition from single filament to filament-surface coupled discharge. The outcomes were a 39.02 % increase in discharge charge and a 15 % increase in output power compared with plasma-only situation. CO₂-conversion optimisation tests showed the formation of a 'microreaction zone' enhanced the development of gas vortices and turbulence, promoting the CO₂-conversion ratio, CO generation ratio, and energy efficiency to 20.64 %, 15.74 %, and 1.864 %, respectively, under the NiFe₂O₄ catalyst-facilitated low-temperature plasma conditions. The conversion route involved generating excited-state CO, O₂, and electrons through plasma ionisation of CO₂, alongside the creation of oxygen vacancies (V_o). These vacancies regenerated by consuming lattice oxygen (O^2-), facilitating CO₂ convert to CO and O₂ by electrons. Furthermore, the catalysts offered sites for adsorbing reaction intermediates, which further facilitated CO₂ dissociation and product formation. The Fe and Ni ions in the NiFe₂O₄ catalyst reacted by redox to produce O^2- and V_o and maintain charge equilibrium.

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.

Meanwhile, phosphorus (P) atoms are doped into the carbon substrate to regulate the local environment of the second shell surrounding the Co site. These simultaneous modifications to the double-shell coordination influence the charge density of the active centers, and ultimately improve their activities.

In-situ thermal monitoring indicates that the chiral nematic liquid crystal phase (CLC) with structural color formed by HPMC under natural drying can uniform the temperature distribution during battery operation. The most important achievement, benefiting from the preeminent thermal stability of CLC special structure, is that the pouch cell assembled with this separator exhibits a lower temperature under nail penetration tests with Φ5 mm and Φ8 mm nail, even without any risk of thermal runaway. The superior cycling stability of the pouch cells under various commercial cathode materials indicates the HPMC coating exists stably in commercial energy storage systems.

The obtained AgSA/Al₂O₃ catalyst exhibited high rates, high tolerance to side reactions with O₂ and H₂O, and high NaBH₄ atomic efficiency for the catalytic hydrogenation of nitroaromatics in aqueous media.
