However, their molecular-scale thickness makes the SAM/perovskite buried interface sensitive to molecular coverage, precursor wettability, and initial nucleation, which can lead to insufficient interfacial coupling and defect-assisted recombination. Herein, we introduce 4-aminobenzenesulfonamide hydrochloride (4–Ah·HCl) as a protonation-enhanced molecular bridge between [4-(7<em>H</em>-Dibenzo[<em>c</em>,<em>g</em>]carbazol-7-yl)butyl]phosphonic acid (4PADCB) and the perovskite absorber. Compared to its neutral counterpart, the protonated NH₃⁺ sites in 4–Ah·HCl exhibit stronger positive electrostatic potential, enhanced hydrogen-bonding capability, and pronounced dipolar characteristics. This facilitates robust N–H···O–P interactions with 4PADCB. The S=O and N–H groups within the sulfonamide moiety interact with interfacial Pb²⁺ and I^– sites and contribute to defect passivation. The modification improves precursor wettability and are associated with denser perovskite films and reduced nonradiative recombination. The modified inverted PSCs achieve a champion power conversion efficiency (PCE) of 25.50% and exhibit improved thermal and storage stability.

Here, we developed a novel nanomaterial platform (SCs-ZIF-8@Au) to perform high-resolution serum metabolic fingerprinting using nanoparticle-assisted laser desorption/ionization mass spectrometry. By integrating machine learning algorithms with metabolic profiling, we established a robust diagnostic model that accurately distinguished MMD from ICAD and healthy controls (HCs). In a cohort comprising 178 MMD patients, 75 ICAD patients, and 103 HCs, our classifier achieved area under the curve (AUC) values of 0.97 (MMD vs HCs), 0.98 (ICAD vs HCs), and 0.88 (MMD vs ICAD). Beyond diagnostics, mechanistic exploration of key metabolic biomarkers revealed that reduced mevalonic acid in MMD impairs endothelial tube formation and migration by disrupting tight junction integrity, attenuating VEGF signaling, and altering calcium homeostasis in human endothelial cells. These findings link dysregulated mevalonate metabolism to pathological angiogenesis in MMD and support its role in endothelial dysfunction.

Here, we construct a Cu₇S₄/CuCo₂S₄ heterostructure in a single hydrothermal process, in which the two phases sharing a common Cu–S sublattice form a coherent interface within individual particles. By fixing the phase ratio independently through Rietveld refinement and benchmarking against both phase-pure constituents under identical conditions, we show that the composite exceeds the composition-weighted rule-of-mixtures prediction by a factor of 3.4 at 0.3 A g^–1. Because the constituents exhibit closely comparable charge–discharge profiles, the redox chemistry itself is unchanged, and this strongly super-additive response can primarily originate from the interface rather than from composition. Elemental mapping and surface-sensitive XPS, together with the coexistence of Li₂S and MgS in in situ XRD, further reveal that storage is spatially partitioned: Li⁺ converts the particle interior while Mg²⁺ reacts predominantly in the near-surface region, so that the two carriers occupy complementary regions of the same particle. Comparing APC-LiCl with APC-LiTFSI at matched salt concentration, and identical in every other respect, localizes the electrolyte effect to the electrode interface, where the chloride-containing system suppresses the progressive Mg-surface passivation that drives continuous overpotential growth in the TFSI^– system. The resulting cell delivers 400 mAh g^–1 at 0.3 A g^–1 and retains 152.56 mAh g^–1 after 330 cycles at 1.0 A g^–1 at ∼100% Coulombic efficiency.

To address this, we developed a core–shell microneedle (GS + IL-4@MN) patch loading Gymnema sylvestre (GS) extract and interleukin-4 (IL-4) as a promising therapeutic strategy. The patch comprised a 10 × 10 array of conical needles and the optimized shell-loading concentration of GS was determined to be 1.0 mg/mL.
