Under pure water-fed conditions, electrochemical reactions occur solely at active sites connected to ionic networks. This study introduces an eco-friendly patterning technique leveraging membrane swelling properties by applying mechanical stress during dehydration under fixed constraints. The method increases active sites by creating additional hydroxide ion pathways at the membrane-electrode interface, eliminating the need for additional ionomers in the electrode. This innovation facilitates ion conduction via locally shortened pathways. Membrane electrode assemblies (MEAs) with patterned commercial membranes demonstrated significantly improved performance and durability compared to MEAs with conventional catalyst-coated substrates and flat membranes under pure water-fed conditions. The universal applicability of this technique was confirmed using in-house fabricated anion exchange membranes, achieving exceptional current densities of 13.7 A cm<sup>-2</sup> at 2.0 V in 1.0 M potassium hydroxide (KOH) and 2.8 A cm<sup>-2</sup> at 2.0 V in pure water at 60 °C.

Their practical application is hindered by the strength, contact resistance, and high cost. Multi-principal elements alloys (MPEAs) provide the possibility to develop cost-effective materials with enhanced mechanical properties. To address this, a novel precious metal MPEA, PdAgCuAuPtZn alloy, is designed, which exhibits significant solid solution strengthening and aging strengthening effects. The ultimate tensile strength increases from 747 MPa in the solution state to 1126 MPa in the aged state, while resistivity remains low. This study presents the first systematic investigation into the strengthening mechanisms of precious metal MPEAs using nanoindentation technology. These findings indicate that the aging strengthening of the alloy is attributed to spinodal decomposition (SD) and chemical short-range order (CSRO) in the matrix. Furthermore, the precipitation structure with Cu-rich and Ag-rich phases gradually replaces the matrix, primarily accounting for aging softening. Additionally, it is discovered that precipitation structure can be strengthened by CSRO formed in the Cu-rich phase, thus providing an innovative strengthening in PdAgCuAuPtZn alloy.

The secretome, derived from hypoxia-preconditioned cardiomyocytes (SHPC), potentially mimics the IPC microenvironment and facilitates IPC clinical translation. This study aims to determine whether SHPC can be a feasible alternative to IPC for attenuating MI/R injury, and to identify the functional factor of SHPC. The ultrafiltration technique is applied to generate an SHPC formulation that is intramyocardially injected before reperfusion in a murine MI/R model. The effects of SHPC on cardiomyocyte apoptosis, pyroptosis, and neutrophil polarization are evaluated. Secretomics, neutralizing antibodies, and recombinant proteins are employed to identify the functional factor in SHPC. Co-immunoprecipitation assays, RNA sequencing, and site-directed mutagenesis are conducted to investigate the underlying mechanism. Additionally, a recombinant functional factor-encapsulated hydrogel is developed for intrapericardial injections (iPC). An intramyocardial SHPC injection in MI/R-injured mice strikingly reduces infarct size and the expression of cardiac injury biomarker while improving cardiac function. SHPC eliminated mitochondrial reactive oxygen species and triggered neutrophil polarization to reduce cardiomyocyte apoptosis/pyroptosis upon hypoxia/reoxygenation injury. Stanniocalcin 1 (Stc1) is identified as the functional factor in SHPC, mediating hypoxic microenvironment. Mechanistically, hypoxia-preconditioned cardiomyocytes secrete Stc1 into the microenvironment and activate calcium-sensing receptor (CaSR) that increases Stat3 phosphorylation at Ser727 via nitric oxide synthase 2 (NOS2)-mediated S-nitrosylation, thereby decreasing cardiomyocyte apoptosis/pyroptosis in an autocrine mechanism. Simultaneously, Stc1 facilitates cardiomyocyte-neutrophil crosstalk, thereby triggering neutrophil polarization to reduce inflammatory damage via the CaSR/NOS2/Stat3 axis in a paracrine mechanism. Pericardial delivery of a recombinant rStc1-encapsulated hydrogel has extended the therapeutic time window of rStc1, improving long-term cardiac function. The hypoxia microenvironment preconditioning, which mimicked by SHPC, attenuated MI/R injury via Stc1-mediated cardiomyocyte self-protection and neutrophil polarization.

Accumulating studies suggest mitochondrial dysfunction as the typical characteristics and key process of AKI, but the underlying mechanism remains elusive. The YME1-like 1 (YME1L1) ATPase, an inner mitochondrial membrane protein, is screened and identified to be downregulated in renal tubular epithelial cells of various mouse models and patients of AKI. Dramatically, restoration of YME1L1 expression significantly alleviates cisplatin-induced AKI and subsequent chronic kidney disease (CKD) through attenuating mitochondrial dysfunction via maintaining optic atrophy 1 (OPA1)-mediated mitochondrial energy metabolism homeostasis. Mechanistically, the upregulated expression of sterol regulatory element binding transcription factor 1c (SREBP1c) is demonstrated to be responsible for cisplatin-mediated transcriptional inhibition of YME1L1 via directly binding to its promoter region. Moreover, cisplatin-induced methyltransferase-like 3 (METTL3)-mediated m6A modification enhances SREBP1c mRNA stability, thereby upregulating its expression. Notably, both depletion of SREBP1c and renal tubule-specific overexpression of YME1L1 markedly ameliorate cisplatin-induced AKI and its transition to CKD.
