All-inorganic, hole-transport-material-free (HTM-free), carbon-based perovskite solar cells (C-PSCs) have garnered significant attention due to their exceptional stability and low cost. However, their performance and commercial potential are still constrained by issues such as poor interfacial contact, insufficient crystallinity, and energy level misalignment. In this work, we tackle these challenges via a molecular engineering strategy by introducing tetrakis(4-ethynylphenyl) methane (TEPM) as a multifunctional additive. The alkynyl moiety (C≡C) in TEPM coordinates with Pb 2+ ions in perovskite precursors, thereby synergistically slowing crystallization kinetics to regulate crystal growth and passivate deep-level defects. As a result, the CsPbI 3 films exhibit larger grain sizes, improved crystallinity, and lower defect densities. Devices modified with TEPM achieved a record power conversion efficiency (PCE) of 20.01% (certified 19.58%). Additionally, unencapsulated devices retained 87.6% of their initial efficiency after 1080 h under ambient conditions (25 °C, 30% relative humidity), and maintained 94.0% of their initial efficiency after 730 h of continuous AM 1.5G illumination in air.

Manganese is essential for zinc electrowinning but its recycling is challenging in oxide ore SX-EW circuits where P204 rejects Mn. This study proposes a novel manganese recycling strategy tailored for SX-EW streams involving the selective SO 2 reductive leaching of zinc anode slime followed by impurity removal. By controlling leaching pH at 5.0 with lime, Mn recovery > 92% while Fe, Ni, Co co-dissolution is suppressed to < 1%, 3%, 12% respectively. Residual impurities in the spent electrolyte are further removed by neutralization and DMDTC chelation. This integrated process effectively recovers manganese while simultaneously eliminating harmful impurities (Cu, Fe, Co, Ni), offering a sustainable solution for Mn management in complex oxide ore hydrometallurgy. The purified electrolyte enabled production of Grade #1 zinc with Pb < 0.005%.

The interplay of charge and spin orders lies at the heart of correlated electron physics and plays a critical role in the emergence of unconventional quantum phases. Kagome magnets provide a particularly promising platform to investigate these phenomena, owing to their geometrically frustrated lattice structure. However, resolving spin and charge orders microscopically and establishing ways to control them remain fundamental challenges. Here, we demonstrate magnetic-field control of an altermagnetic spin density wave order intertwined with charge density wave order in kagome magnet CsCr 3 Sb 5 . Scanning tunneling microscopy down to deep cryogenic temperature of 50 mK reveals two previously unreported charge density wave orders. Density functional theory confirms that one of them, a 4 \({a}_{0}\times \sqrt{3}{a}_{0}\) charge order, is coupled to a spin density wave with an altermagnetic ground state. The charge density waves can be tuned in both amplitude and phase by an external magnetic field, reflected in domain switching and stripe sliding of the charge density wave. Our findings deepen the understanding of symmetry-breaking in kagome systems, providing a tunable platform to explore the interplay of electronic correlation with emergent quantum magnetism.

Developing efficient and stable electrocatalysts is key to converting 5-hydroxymethylfurfural (HMF) into the value-added product 2,5-furandicarboxylic acid (FDCA). Herein, a three-dimensional porous nanosheet-structured nickel-molybdenum-copper (NiMoCu) ternary catalyst was constructed on nickel foam via a two-step electrodeposition strategy coupled with alkaline heat treatment. Characterization (XRD, Raman, TEM, XPS) revealed the homogeneous integration of Ni, Mo, and Cu species at the nanoscale, forming multiple heterointerfaces (MoO 3 –CuO/NiOOH). Meanwhile, Cu incorporation refined the MoO 3 crystallite size to 8.2 nm and promoted the in situ formation of amorphous NiOOH containing Ni³⁺ species. Furthermore, the interfacial electron transfer effect optimized charge transport pathways, thereby promoting an efficient HMFOR process. At 1.47 V vs. RHE, this catalyst showed record HMF electrooxidation performance. The HMF conversion was 99%, FDCA selectivity was near 100%, FDCA yield was 98%, and Faradaic efficiency was 98%. After four cycles in a row, the yield dropped by less than 2%. The excellent performance of the NiMoCu catalyst comes from the synergy of its three metals. Ni³⁺ acts as the active center and drives the reaction. Mo 6+ keeps the Ni³⁺ state stable and speeds up charge movement. Cu stops the side oxygen evolution reaction (OER). The OER contribution is under 2%. This work offers a new way to design efficient and stable catalysts for the electrocatalytic conversion of HMF, a key biomass platform compound.

Aqueous zinc-ion batteries have emerged as a highly promising energy storage technologies due to their abundant resources, high safety, and environmental friendliness. However, the cycle stability of Aqueous zinc-ion batteries is severely constrained by zinc dendrite growth on the anode and accompanying side reactions in the electrolyte. Mitigating this effect is crucial for the large-scale application of zinc-ion batteries, and separator modification is regarded as an effective strategy to address these challenges. Here, a method of modifying the glass fiber composite separator with amino-functionalized MXene (Ti₃C₂Tₓ) is attempted to alleviate these problems. The modified Ti₃C₂Tₓ was uniformly loaded on the surface of glass fiber separator by vacuum filtration to fabricate the composite separator. Systematic characterization and electrochemical testing revealed that the composite separator with an optimal coating loading of 2 mg cm⁻² significantly enhanced battery performance. The cycle life of Zn//Zn symmetric cells were markedly extended at 5 mA cm⁻², and specifically, reached 250 h at 0.5 mA cm⁻², which is about 8 times longer than that of the unmodified glass fiber separator (~ 30 h). Furthermore, the Zn||MnO₂ all-cell based on this composite separator also exhibited a higher capacity retention rate after 1200 cycles compared to the blank separator group. This provides an effective research direction for the design of high-performance Aqueous zinc-ion batteries separators. Graphical abstract

Conventional polymeric fibrous sponges, as universal passive acoustic control materials, provide a sustainable approach to noise mitigation. However, addressing the narrow effective acoustic bandwidth and inherent flammability remains challenging. Here, a fire-resistant hybrid fibrous sponge (HYFS) featuring broadband acoustic absorption is fabricated by the strategy of spontaneous hollowing and sacrificial template-assisted dynamic hybridization. The hierarchical phase separation within a solution jet enables the concurrent hollowing and three-dimensional self-assembly of ultrafine fibers in one step. Subsequently, a continuous inorganic sheath induced by template sacrifice was generated on the hollow fibers, forming a dynamically evolved multi-scale structural regulatory system, ranging from the microtubular fibers with hollow channels and nanoscale surface roughness to macroscopic fibrous assemblies with open inter-fiber porosity. Thus, the prepared HYFS demonstrates a remarkable noise-reduction coefficient of 0.62 at 270 g/m 2 , along with the broadband sound absorption of effective bandwidth up to 5.5 kHz (sound absorption coefficient > 0.90). Moreover, it demonstrates outstanding fire retardancy with a peak heat release rate of 7 kW/m 2 , representing a 75% reduction compared to the prepared polyimide sponges. This work sheds light on a novel avenue to the scalable fabrication of ultralight, fire-safe, and highly efficient broadband acoustic absorbers for practical applications. Graphical

Organic-inorganic hybrid metal halides have attracted considerable attention due to their structural diversity and promising optoelectronic properties. Although photoluminescence has been observed in hybrid zinc-based halides, the underlying emission mechanisms remain a topic of debate. In this study, we synthesized three phenylethylamine hybrid zinc halides, (C 8 H 12 N) 2 ZnX 4 (X = Cl, Br, I), which feature zero-dimensional (0D) structures consisting of isolated [ZnX 4 ] 2− tetrahedral units surrounded by organic C 8 H 12 N⁺ cations. Upon photoexcitation, these compounds exhibit blue-white emission. Comprehensive experimental analysis suggests that the emission originates from intrinsic lattice defects, specifically zinc interstitials, and radiative transitions from the conduction band to deep-level states. Our findings confirm the presence of defect states in zinc-based halides and reveal that these defects simultaneously act as luminescence centers and limit the overall emission efficiency, contributing to the relatively low photoluminescence quantum yield (PLQY) observed in these materials.

Hydrogel electrolyte based secondary batteries are promising for wearable electronics, yet face challenges including limited mechanical resilience, and narrow temperature range. Herein, we report a robust deep-eutectic hydrogel electrolyte fabricated via synergistic interplay of dual nanophase separation, hydrated eutectic solvation, and hydrogen-bond networks. The interwoven nanophase separation architecture, integrating hydrophilic polyvinyl alcohol phases and hydrophobic polyacrylonitrile phases, realizes high fracture-strength (4.1 MPa) and toughness (13.66 MJ m −3 ). Meanwhile, deep-eutectic chemistry modulates Zn 2+ solvation structures and leverages cyano-coordination channels of polyacrylonitrile to achieve high Zn 2+ ionic conductivity (28.2 mS cm −1 ) and transference number (0.65) at 20 °C. Concurrently, abundant hydrogen bonds induced by multiple donor sites of hydrophilic phases, urethane, and Zn(ClO 4 ) 2 immobilize active H 2 O to ensure broad-temperature durability. This tripartite synergy directs planar Zn deposition along (002) planes and suppresses dendrite growth, enabling Zn||I 2 batteries with a thinner-than-paper thickness (42 μm) and high flexibility. The assembled Zn||I 2 batteries demonstrate high specific energy (108.99 Wh kg −1 ) and cycling stability (over 36,000 cycles under −40 to 80 °C). In this work, the convergence of molecule design, phase modulation, and process engineering establishes a feasible methodological framework for developing advanced flexible batteries that integrate high energy density and harsh environment tolerance.

The design of superionic conductors has been largely focused on static structural features, with the dynamic ion transport mechanism less explored. Here, we explore a paradigm that harnesses the polyanion rotations to trigger the dynamically disordered Li sublattice as well as the liquid-like cation diffusion for superior ionic conductivity in crystals. A descriptor called rotation tolerance factor was proposed as a predictive metric for identifying the potential fast-rotating anion clusters with the low mass and reduced valence charge for given structural frameworks. Guided by this factor, halides with rotational polyanions, namely Li 3 Y(SH) 6 , Li 3 Y(NH 2 ) 6 , Li 2 Zr(NH 2 ) 6 , and an oxide (Li 6.5 La 3 Zr 2 O 11.5 (NH 2 ) 0.5 ) have been designed with synergistic polyanion rotation and Li⁺ sublattice disorder, which lead to enhanced Li ionic conductivities at room temperature compared to the counterparts without polyanions. The experimentally synthesized NH 2 - incorporated Li 2 ZrCl 5.92 (NH 2 ) 0.08 demonstrates a four-fold higher conductivity over Li 2 ZrCl 6 control, enabling all-solid-state Li-In | |LiCoO 2 and Li-In | |LiNi 0.88 Co 0.09 Mn 0.03 O 2 cells with 96.5% and 97.4% capacity retention after 190 cycles at 140 and 200 mA g -1 , respectively. This work provides an insight that flexible anion rotations could promote the dynamically disordered lithium sublattice distribution as well as the ionic conductivity.

Background Colorectal cancer (CRC) remains one of the most commonly diagnosed malignancies worldwide and is associated with high recurrence and poor survival outcomes, particularly in its advanced stages. Zi-Shen-Gu-Sui Decoction (ZSGSD), a traditional Chinese medicinal formula, has been clinically applied in CRC treatment and postoperative rehabilitation; however, its pharmacological mechanisms are not yet fully elucidated. This study aimed to explore the anti-CRC efficacy and molecular mechanisms of ZSGSD, with particular attention to the PI3K/AKT/mTOR signaling axis. Methods UPLC-Q-Orbitrap HRMS was utilized to characterize the chemical profile of ZSGSD. Network pharmacology was employed to identify key signaling pathways and bioactive compounds, and molecular docking was conducted to predict potential interactions between major constituents and PI3K/AKT/mTOR proteins. A xenograft mouse model of CRC was established to evaluate tumor suppression. Histological staining was used to assess apoptosis, and the expression of PI3K, AKT, and mTOR was quantified via RT-qPCR, Western blotting, and immunofluorescence assays. Results Sixty compounds were identified in ZSGSD, with flavonoids comprising approximately 50%. Network analysis suggested potential involvement of the PI3K/AKT/mTOR pathway, and docking results indicated favorable predicted binding between key flavonoids (including Genistein, Apigenin, and Naringenin) and proteins within this pathway. In vivo, ZSGSD treatment suppressed tumor growth in a dose-responsive fashion, with tumor inhibition rates ranging from 30.83% to 75.23% ( p < 0.05). Histological evaluations revealed reduced nuclear-to-cytoplasmic ratios and enhanced apoptotic activity, as confirmed by TUNEL staining ( p < 0.05). Molecular analyses showed a dose-related reduction in PI3K, AKT, and mTOR expression at the transcript and protein levels, indicating that this pathway may be modulated during ZSGSD treatment ( p < 0.05). Conclusion ZSGSD demonstrates notable tumor-suppressive and pro-apoptotic effects in a CRC xenograft model. These outcomes appear to be associated with modulation of the PI3K/AKT/mTOR signaling pathway, although further functional studies are required to confirm pathway specificity and clarify causal mechanisms.

Basic Fuchsin (BF), a recalcitrant organic dye, poses severe risks to aquatic ecosystems and human health, necessitating the development of efficient and stable environmental remediation technologies. Herein, a novel direct S-scheme heterojunction photocatalyst (MG-CQDs/TiO 2 ) was prepared by impregnating and calcining TiO 2 with mango peel-derived carbon quantum dots (MG-CQDs). The successful construction of the S-scheme charge-transfer heterostructure was systematically elucidated through band structure analysis and electron paramagnetic resonance (EPR) spectroscopy. Under ultraviolet–visible (UV–Vis) light irradiation, the MG-CQDs/TiO 2 composite exhibited exceptional photocatalytic performance, achieving a remarkable BF degradation efficiency of 96.5% within 180 min. Notably, its reaction rate constant was 2.1 times higher than that of pristine TiO 2 . Mechanistically, the synergistic interaction between MG-CQDs and TiO 2 significantly promotes the spatial separation of photogenerated carriers. Radical trapping experiments further confirmed that superoxide (·O 2 − ) and hydroxyl (·OH) radicals serve as the primary reactive oxygen species driving the oxidation process. Crucially, density functional theory (DFT) calculations combined with Fukui index analyses provided molecular-level insights into the degradation pathway, identifying the nitrogen atoms and the central carbon of the BF molecule as the preferential sites for radical attack. Furthermore, the composite demonstrated outstanding photostability, maintaining highly efficient degradation over multiple consecutive cycles. Supported by both macroscopic experimental evidence and microscopic theoretical calculations, this study presents a highly efficient, cost-effective, and green paradigm for the advanced treatment of industrial dye wastewater.
