Elevating the charging cutoff voltage of cathode materials is an effective strategy to improve the energy density of ASSLBs. However, the limited oxidative stability of solid-state electrolytes (SEs) and structural and chemically irreversible changes in the cathode active material result in inferior electrochemical performance. Here, we synthesized nano-Li_1.2Al_0.1Ta_1.9PO₈ (LATPO) coatings on the surface of lithium cobalt oxide (LCO) by a facile ball-milling method combined with heat treatments. This artificial intermediate phase effectively enhances the structural stability and interfacial transport kinetics of the cathode and mitigates continuous side reactions at the cathode/solid electrolyte interface. As a result, the ASSLBs with modified LCO cathode exhibit a reversible capacity of 203.5 mAh g⁻¹ at 0.1 C and 4.0 V (corresponding to the potential of 4.6 V vs. Li⁺/Li), superior cycling stability (85.4% capacity retention after 500 cycles), a high areal capacity (4.6 mAh cm⁻²), and a good rate capability (62 mAh g⁻¹ at 3 C).

The PP-MgSi composite patch was manufactured via electrospinning and characterized by controllable degradation and local release of Mg²⁺ and SiO₃²⁻. The patch showed favorable in vitro biocompatibility and bioactivity, notably increased angiogenesis, myelination, and neurite outgrowth. In type 2 diabetic mice, the PP-MgSi patch exhibited MgSi dose-dependent effects on enhancing diabetic wound healing by modulating the expression of TNF-α, iNOS, and CD206 to balance inflammation, while boosting CD31 and β3-tubulin levels to promote neurovascularization. With the significant suppression of pro-inflammatory-related TNF and IL-17 pathways, while activating the peripheral nerve-associated axon guidance pathway, blood vessel-associated HIF-1α and VEGF pathways, the PP-MgSi patch ultimately achieved accelerated healing compared to the control group. Ultimately, the PP-MgSi patch exhibited an accelerated repair rate, with comparable neovascularization and superior peripheral nerve regeneration capacity compared to three representative commercially available products.

The limited understanding of the pathological characteristics of HS restricts the therapeutic efficacy of current strategies. In this study, we first identified the elevated mitophagy and suppressed apoptosis in hypertrophic scar fibroblasts (HSFs), which combined with excess inflammation to constitute the pathological microenvironment of HS, driving us to develop a functionalized microneedle (MN) patch for inhibiting mitophagy, promoting apoptosis and modulating inflammation to adapt HS treatment. The MNs integrate curcumin-loaded HSFs-derived extracellular vesicles (Cur@EV) and a decellularized extracellular matrix from umbilical cord-derived mesenchymal stem cells (UC-MSCs-dECM, UdECM). The homologous Cur@EV with enhanced cellular uptake significantly induced HSFs apoptosis via mitophagy inhibition, meanwhile reducing collagen deposition. Meanwhile, the UdECM exerted immunomodulation capacity by facilitating the M2 polarization of macrophages, aiding in the suppression of HSFs. Notably, the Cur@EV/UdECM-functionalized MN patches exhibited regenerative therapeutic outcomes on a rabbit HS model, with HS inhibition and new hair follicle formation. Overall, this study presents a synergistic strategy based on the regulation of “mitophagy-apoptosis-inflammation,” offering a novel, minimally invasive approach for HS management. The integration of homologous Cur@EV and UdECM into an MN patch represents an innovative, multifunctional approach that combines mitophagy inhibition, apoptosis induction, and immunomodulation. The regenerative outcomes observed in the rabbit HS model, including hair follicle formation, further underscore the translational potential of this strategy.

This approach employs thermokinetic feature engineering to optimize data quality and algorithm selection, thereby reducing dependence on data scale and computing power resources. Specific thermokinetic activation patterns for formaldehyde can be generated through a single materials processing strategy.

The mathematical model reveals that the physicochemical mechanism of odor coding logic in our e-nose is dictated by the mass action law. A quantitative detection of formaldehyde in 0.1–20 ppm with a precision of 5% full-scale (F.S.) has been demonstrated. We also showcase the adaptability of e-nose for binary mixture analysis.
