The development of aqueous battery with dual mechanisms is now arousing more and more interest. The dual mechanisms of Zn 2+ (de)intercalation and I − /I 2 redox bring unexpected effects. Herein, differing from previous studies using ZnI 2 additive, this work designs an aqueous BiI 3 -Zn battery with self-supplied I − . Ex situ tests reveal the conversion of BiI 3 into Bi (discharge) and BiOI (charge) at the 1st cycle and the dissolved I − in electrolyte. The active I − species enhances the specific capacity and discharge medium voltage of electrode as well as improves the generation of Zn dendrite and by-product. Furthermore, the porous hard carbon is introduced to enhance the electronic/ionic conductivity and adsorb iodine species, proven by experimental and theoretical studies. Accordingly, the well-designed BiI 3 -Zn battery delivers a high reversible capacity of 182 mA h g −1 at 0.2 A g −1 , an excellent rate capability with 88 mA h g −1 at 10 A g −1 , and an impressive cyclability with 63% capacity retention over 20 K cycles at 10 A g −1 . An excellent electrochemical performance is obtained even at a high mass loading of 6 mg cm −2 . Moreover, a flexible quasi-solid-state BiI 3 -Zn battery exhibits satisfactory battery performances. This work provides a new idea for designing high-performance aqueous battery with dual mechanisms.

Cold tumors evade APC and T‐cell surveillance through low immunogenicity, defective antigen presentation, and immunosuppressive tumor microenvironments. We uncovered a non‐canonical function of bacterial outer membrane vesicles (OMVs), whereby OMVs activated the TLR4–NF‐κB–NLRC5 axis to induce tumor MHC I upregulation, thereby restoring tumor visibility to T cells. To further eliminate tumor invisibility to APCs, we reported a bacteria‐inspired strategy that drives APCs to perceive tumor cells as bacteria. By fusing OMVs with fusogenic liposomes, we constructed fusogenic OMVs (FOs) that anchor bacterial membrane components onto tumor surfaces, thereby functionally “bacterizing” tumor cells. This modification markedly increased APC recruitment and effectively reprogrammed APC perception from silent tumor clearance to active microbial‐like immune surveillance. Consequently, APCs exhibited enhanced phagocytic uptake of bacterized tumors, enabling efficient cross‐presentation of the tumor‐antigen repertoires to T cells. Concurrently, OMVs upregulated MHC I expression on tumor cells, which strengthened effector T cell recognition and cytotoxicity toward tumors. Furthermore, by loading 3‐bromopyruvate into the vesicles, we endowed the system with metabolic reprogramming capability, characterized by glycolysis suppression and lactate depletion. Together, the synergistic immune–metabolic modulation resulted in durable suppression of tumor progression following intratumoral administration, offering a bacterization‐inspired nanoplatform to overcome key immunological barriers in immune‐cold tumors. Tumor bacterization by fusogenic outer membrane vesicles enhances microbial‐like recognition of tumor cells while activating the TLR4–NF‐κB–NLRC5 axis to upregulate MHC class I expression. By simultaneously strengthening APC sensing and T‐cell recognition, this strategy breaks tumor immune invisibility and promotes more effective antitumor immune surveillance.

Given the widespread availability of low-grade heat (< 100 °C), its conversion into electricity represents a highly promising green technology. Thermo-electrochemical cells (TECs) have garnered significant attention for their potential in low-grade thermal energy harvesting, largely due to their relatively high thermopower. An efficient approach to achieve high thermopower is establish a high and stable concentration gradient (∆C). However, the ∆C construction process is often limited by a false saturation state in conventional I − /I 3 − TECs. To address this issue, we propose a enhancement strategy that utilizes a non-additive ion effect to enhance the free energy of hydrophobic ions. Specifically, the addition of strongly hydrating anions (SO 4 2− ) disrupts the coordination between weakly hydrating I 3 − ions and cations (K + ) by competitively occupying the K + coordination site. The free energy of I 3 − raise effectively and promote the hydrophobic interaction with methyl cellulose (MC), breaking the false saturation state and enabling a significantly greater ∆C. The implement of this strategy gets a high thermopower of 18.41 mV K −1 in this gel-based TECs. Moreover, a module comprising six series-connected devices produce a stable output of 520 mV under a 5 °C temperature difference. This work highlights the untapped potential of traditional systems for efficient thermal energy harvesting, offering a new strategy to overcome this false saturation state.

CuSn-codoped CdS (CdS:CuSn) quantum dots (QDs) with different Cu(I) and Sn(IV) doping levels have been successfully synthesized by a simple one-pot procedure. It was found that the doping ratio of Cu(I) and Sn(IV) in CdS QDs significantly affected the photoluminescence (PL) quantum yields (QYs), Stokes shifts, and emission window of as-prepared QDs. Compared to single Cu doping, CuSn codoping further significantly improved the PL QYs of as-prepared QDs (up to 24.6%). The CdS:CuSn QDs may be used as potential emitters in the PL industry.

Cardiac Troponin I (cTnI), a critical biomarker for diagnosing acute myocardial infarction (AMI), plays an essential role in clinical practice. While traditional lateral flow immunoassays (LFIA) are widely used for cTnI detection due to their simplicity and rapid results, they often suffer from limited quantification capability, low sensitivity, and compromised accuracy, limiting their broader clinical application. To overcome these issues, we developed a dual-signal LFIA (dLFIA) by incorporating Au@CoO nanoparticles (NPs) for quantitative and precise cTnI determination. The synthesized Au@CoO NPs present black color as colorimetric signals and its peroxidase-like activity was adopted to yield chemiluminescence (CL) signals. It is worth noting that sodium perborate was employed to replace hydrogen peroxide as the co-reactant for the aim of enhancing long-term stability and CL intensity. Such dual-signal strategy offers self-checking merit, significantly improving detection reliability. What is more, a portable assay device was designed for automatic release of the reagents involved, further simplifying the detection process. The dLFIA demonstrated a wide linear range with limits of detection of 0.39 ng/mL in colorimetric mode and 0.22 ng/mL in chemiluminescent mode, which are 8 and 15 times more sensitive than traditional LFIA, respectively. This dLFIA platform can act as a promising assay tool for point-of-care testing, particularly in AMI diagnosis and potentially in other applications.

With excellent thermal and chemical stability, tin dioxide (SnO2) has emerged as a promising electron transport layers (ETLs) for the high-efficiency n–i–p perovskite solar cells (PSCs). However, for perovskite films deposited on SnO2, the surface hydroxyl groups of SnO2 and lattice mismatch lead to severe nonradiative charge recombination at the buried interface. Moreover, the inherent brittleness of perovskite renders the buried interface mechanically more vulnerable. In this work, a dipolar π-conjugated molecule, 3,5-diaminobenzotrifluoride (CF3-mDA), is employed as a buffer layer to modify the buried interface of PSCs with a relatively wide bandgap (1.60 eV). This buffer layer effectively coarsens the perovskite grains at the buried interface, increasing the grain size from 381.50 nm to 503.47 nm, and further enhances the mechanical toughness of the buried interface and mitigates the risk of interfacial fracture. Furthermore, it passivates the defects of both SnO2 and perovskite through its functional groups, as well as induces a more favorable energy band alignment. With this buried interface modification, the champion device delivers an average power conversion efficiency (PCE) increased from 18.74% to 21.93% (22.12% under reverse scan, RS, and 21.74% under forward scan, FS), with an average open-circuit voltage (VOC) boosted from 1.188 V to 1.232 V and a significantly suppressed hysteresis. The modified devices also show a higher environmental stability than the control counterparts, maintaining an average 85.20% of their initial PCE after 16 days of storage in ambient air (with 25% relative humidity, RH, and at room temperature, RT).

Porous liquids (PLs), combine the high adsorption capacity of porous solids with the fluidity of liquids, show great promise in selective CO 2 capture. However, current studies on Type I PLs lacks systematic investigations into the regulatory role of porous host particle size and its impact on in-depth analysis of the gas sorption-separation process. Herein, we successfully fabricated PLs by grafting polyether amine oligomer chains onto the surface of size-tailored UiO-66-OH as the porous host, which endow the PLs with good thermal stability, transparency, low viscosity, and promising CO 2 /N 2 separation. UiO-66-OH-PLs were fabricated by grafting polyether amine oligomer steric solvent onto UiO-66-OH via dehydrative condensation. The effect of porous host size on CO 2 separation behavior of UiO-66-OH-PLs and the selective sorption-separation mechanism were systematically investigated using sorption isotherm and kinetic models. UiO-66-OH-PLs exhibit markedly enhanced CO 2 sorption capacity relative to the pure steric solvent, confirming the preservation of accessible cavities in porous hosts. The PLs further exhibit distinct size-dependent physicochemical and sorption properties as decreasing the particle size of UiO-66-OH porous hosts increases oligomer grafting density, reduces bulk viscosity and enhances both CO 2 sorption capacity and CO 2 /N 2 separation selectivity. CO 2 adsorption isotherms are best fitted by the SS-Langmuir-Freundlich model, indicating that CO 2 sorption by UiO-66-OH-PLs is single-component sorption on heterogeneous surfaces, integrating Langmuir monolayer sorption and Freundlich non-ideal sorption characteristics. Kinetic analysis reveals that the optimal pseudo-first-order kinetic model, demonstrating that CO 2 sorption rate is dominated by the sorption-desorption process between adsorbate molecules and adsorbent surface-active sites, rather than intraparticle or liquid film diffusion. This work opens up a promising avenue for the rational design of high-performance PLs that can be tailored to meet the demands of practical industrial chemical separation processes.

Iodine (I 2 ) cathodes for aqueous Zn–I 2 batteries suffer from sluggish redox kinetics and severe polyiodide shuttling, resulting in poor utilization and cycling stability. Herein, graphitic nitrogen-enriched carbonized polymer dots (CPDs) with a core–shell structure are integrated with a self-supporting porous carbon framework to construct a graphitic nitrogen-regulated porous carbon host. The porous framework provides abundant space for iodine accommodation and accessible pathways for mass transport, while CPDs introduce graphitic-N sites that strengthen iodine–host interactions and facilitate interfacial electron transfer. Their cooperative action favors a dominant direct I 2 /I − conversion pathway with substantially suppressed accumulation of soluble polyiodide species, thereby enabling fast iodine redox kinetics and excellent cycling stability. Benefiting from these synergistic effects, the optimized PCF-CPDs/I 2 -0.2 cathode delivers a high specific capacity of 146.1 mAh g −1 at 0.3 A g −1 with 99.6% capacity retention over 500 cycles. At 1 A g −1 , it maintains 117.5 mAh g −1 with 87.1% retention after 4000 cycles. This work demonstrates that coupling porous confinement with CPDs-mediated interfacial regulation provides an effective strategy for developing high-performance Zn–I 2 batteries. Graphical Graphitic-N-enriched carbonized polymer dots (CPDs) are integrated into a self-supporting porous carbon framework (PCF) to couple porous confinement with CPDs-mediated interfacial regulation. The resulting PCF-CPDs/I 2 -0.2 cathode substantially suppresses detectable accumulation of soluble polyiodide species, favors a predominantly direct I 2 /I − conversion pathway, facilitates interfacial charge transfer, improves iodine utilization, and enables long-term cycling stability in aqueous Zn–I 2 batteries.

Brucellosis, acting as a typical chronic zoonotic disease, is caused by the invasion ofBrucellainto the human body. Outer membrane protein 25 (Omp25), specifically localized on theBrucellamembrane, is the main virulence factor ofBrucellaand participates in multiple links of the damage process. Omp25c, a porin protein ofBrucella, is a paralog of Omp25 with high sequence identity. NADH dehydrogenase [ubiquinone] complex I assembly factor 2 (Ndufaf2) has a key function in cell energy metabolism, particularly in the formation and activity of the mitochondrial respiratory chain. Loss of Ndufaf2 results in oxidative stress and mitochondrial DNA (mtDNA) deletion. However, the functional relationship between Omp25c and Ndufaf2, the underlying mechanism of the proteins, remains unclear. In this work, we purified the Omp25c and Ndufaf2proteins. Our data revealed that Omp25c directly interacts with Ndufaf2, as determined using Biacore analysis. In addition, assays revealed that Ompa2c reshapes the host cell’s redox environment by decreasing the oxidized nicotinamide adenine dinucleotide/reduced nicotinamide adenine dinucleotide (NAD+/NADH) ratioand adenosine triphosphate (ATP) production, whereas Ndufaf2 exerts an opposing regulatory effect; Co-expression results further revealed an antagonistic relationship between the two during metabolic processes. These findings provide a new perspective for elucidating the mechanisms of mitochondrial functional regulation inBrucella–host interactions and lay the theoretical and experimental foundation for drug development targeting metabolic interventions to eliminate intracellular pathogens.

The degradation of complex plant polysaccharides, particularly Rhamnogalacturonan I (RG-I) pectin, is essential for unlocking the value of biomass. This study focuses on the enzymatic toolbox of Penicillium oxalicum for efficient RG-I breakdown. Here, we recombinantly expressed 15 novel pectinolytic enzymes and characterized their biochemical functions. The enzyme system consists of backbone-cleaving rhamnogalacturonan hydrolases and lyases, along with side-chain–degrading enzymes. Specific endo-β-galactanases (GH30, GH43, GH53) and an exo-β-galactosidase (GH35) collaboratively hydrolyze galactan side chains. Meanwhile, α-arabinanases (GH43) and exo-α-arabinofuranosidases (GH54, GH62) work synergistically to degrade arabinan side chains. Through coordinated action, these enzymes achieve complete degradation of complex RG-I structures. Our findings provide a comprehensive enzyme set for targeted polysaccharide deconstruction, offering valuable resources for biomass conversion and pectin valorization in industrial applications.

Zearalenone (ZEN) is a common mycotoxin widely present in food and agricultural products, posing a serious threat to human health. This work developed a fluorescent/smartphone-assisted colorimetric dual-mode aptasensor for detecting ZEN. Platinum nanowires-supported MXene (PtNWs/MXene) composites exhibit peroxidase-like (POD) activity, which can be inhibited by the adsorbed ZEN-specific DNA aptamers. In the presence of ZEN, the specific binding between ZEN and the aptamer triggers desorption of the aptamer from the PtNWs/MXene surface, thus restoring the POD activity of composites. With hydrogen peroxide introduced, PtNWs/MXene catalyzes the oxidation of colorless o-phenylenediamine into colored 2,3-diaminophenazines, simultaneously generating a fluorescent signal. Exonuclease I mediates target cycling to achieve signal amplification, further boosting the detection sensitivity. The smartphone-based colorimetric mode shows a linear detection range of 10 ~ 900 ng/mL with a limit of detection (LOD) of 6.57 ng/mL, while the fluorescence mode presents a linear range of 1 ~ 1000 ng/mL and a LOD as low as 0.74 ng/mL. This sensing platform can accurately distinguish ZEN-positive and ZEN-negative samples, and the detection results are highly consistent with those of ELISA. It provides an efficient and reliable new solution for highly sensitive on-site ZEN detection, demonstrating significant application potential in food safety monitoring.

The equilibrium mole fraction solubility of tanshinone I in acetone, N,N-dimethylformamide (DMF), methanol, ethanol, water, ethylene glycol (EG), n-propanol, isopropanol, and 1-butanol as well as methanol/ethanol/DMF/acetone + water was determined by the isothermal saturation method at 278.15–323.15 K under 101.2 kPa. The temperature and the composition of solvent mixtures play a decisive role in the solubility of tanshinone I. Then, four monosolvent models (Apelblat, van’t Hoff, λh, and NRTL) and three cosolvency models (Jouyban–Acree (J-A), van’t Hoff–Jouyban–Acree (V-J-A), and modified Apelblat–Jouyban–Acree (A-J-A)) were utilized to correlate the mole fraction of tanshinone I. The maximum deviation (relative average deviation (RAD) and root-mean-square deviation (RMSD)) between the experimental data and the solubility data calculated by the monosolvent models are 6.21% and 3.02 × 10–4, respectively. The maximum of RAD and RMSD for the mixture systems are 1.58% and 1.35 × 10–4, respectively. The Kamlet and Taft linear solvation energy relationship model was used to analyze the solvent effect, and the nonspecific dipolarity/polarizability interactions between the solute and solvent played a major promoting role. All in all, the experimental and computational data are able to provide basic data for the optimization and improvement of the recrystallization process of tanshinone I.
