Ozonized sunflower oil has been found to have a valuable antimicrobial activity against bacteria, viruses, and fungi. However, delayed cutaneous wound healing, severe adverse skin reactions such as pain, burns, irritation, and unsatisfactory storage stability have limited its clinical use as it is known that the performance of ozonized sunflower oil is reflected by core indicators such as iodine value (IV), peroxide value (PV), and acid value (AV). Aiming to improve the above characteristics, ozone oxidation conditions such as the oil water content of raw materials, stirring speed, and ozonized time were successfully optimized, and the optimized conditions were 5%, 300 rpm, and 6 h, respectively. Additionally, the UHPLC-Q-Exactive Orbitrap MS was used to identify the compounds of sunflower oil and ozonation sunflower oil, and 10 fatty acids were successfully identified. The results clearly indicated that the ozonized sunflower oil prepared under optimized ozonation conditions achieved a high degree of ozonation (II) and a satisfactory PV/AV ratio. These optimized conditions further proved to be valuable in improving not only the storage stability of ozonized sunflower oil for up to six months but also in ensuring its remarkable antimicrobial effects on Staphylococcus aureus and Candida albicans, with a PV of 165.75 mmol/kg achieving a 100% antibacterial efficacy.

Photoreforming of plastic waste offers a solution for reducing environmental pollution while producing value-added products. This study investigates the impact of conduction band edge modulation on the photoreforming efficiency of waste polyethylene terephthalate (PET) using a TiO2/black phosphorus nanosheet (BPNS) heterojunction catalyst, leveraging the tunable bandgap and high carrier mobility of BPNSs. The BPNS/TiO2 heterojunction demonstrated remarkable PET degradation under simulated solar illumination, achieving an 80% weight loss after 35 h. Simultaneously, the system exhibited efficient hydrogen evolution, producing 345.2 μmol g–1 h–1 of H2. Bandgap modulation analysis revealed that as the conduction band edge (ECB) of the photocatalyst became more negative, the increase in CO evolution rates surpassed those of H2 and CO2, likely due to enhanced charge transfer, stronger oxygen adsorption, and a more negative reduction potential. The influence of bandgap tailoring on charge separation, transfer dynamics, and oxygen radical generation, directly linked to photoreforming efficacy, was analyzed through EIS, ESR, and DFT calculations. This study underscores the potential of BPNS/TiO2 heterojunctions for efficient and selective photoreforming of different plastic waste, offering valuable insights into catalyst design for environmental remediation and energy recovery.

The severe side reactions caused by H 2 O molecules and polyiodides, along with rampant dendrite growth have critically impeded the progress of aqueous zinc-iodide batteries (ZIBs). Herein, we propose a strategy for in-situ constructing a zinc oxalate protective layer with an ordered nanocube structure (ZCO NC) on the surface of Zn metal anode (ZMA). This approach aims to remove the superficial passivation layer of ZMA and simultaneously suppress the formation of dendrites and the occurrence of parasitic reactions via a facile and cost-effective oxalic acid etching process. Initially, the removal of passivation layer homogenizes the ion distribution near the electrode, alleviating concentration polarization. Secondly, the ZCO NC protective layer serves as a robust physical barrier to resist the attack of H 2 O molecules, while simultaneously trapping free and active H 2 O molecules to accelerate Zn 2+ migration at the electrode/electrolyte interface through its high H 2 O affinity, in turn restraining H 2 O-triggered side reactions and dendrite growth. Moreover, the ZCO NC protective layer can immobilize I 3 − on the surface of the Zn anode, thus preventing the polyiodide-related corrosion. Benefiting from these synergistic effects, the symmetric cell with Zn@ZCO NC exhibit an extended lifespan of 1800 h at 1 mA cm −2 , while ZIBs demonstrate exceptional cycling stability with a discharge specific capacity of 121 mAh g −1 after 6000 cycles at 1 A g −1 .

Fenton oxidation technology utilizing hydrogen peroxide is recognized as an effective method for producing reactive oxygen species (ROS) to facilitate the degradation of antibiotics. However, the requirement for strongly acidic conditions during this process significantly restricts its broader applicability. In this study, we synthesized black phosphorus (BP) nanosheets by exposing the {010} crystal planes and then constructed a 0D/2D BP/Bi2MoO6(PBMO) heterojunction to function as a Fenton catalyst. The PBMO-75 heterojunction exhibited a remarkable increase in photo-Fenton catalytic activity towards oxytetracycline (OTC) under neutral conditions, achieving catalytic efficiencies that were 20 and 8 times greater than those of BP and Bi2MoO6(BMO), respectively. This can be attributed to its strong absorption of visible light, the establishment of an internal electric field (IEF) at the interface, and the implementation of a Z-scheme catalytic mechanism. Additionally, the photo-Fenton system was further improved in OTC degradation through the continuous conversion of Mo6+/Mo5+under visible light irradiation in conjunction with H2O2. Based on ERS, XPS, and active species trapping experiments, we propose a Z-scheme charge transfer mechanism for PBMO. This research offers compelling evidence that 0D/2D Z-scheme heterojunctions are promising candidates for the photo-Fenton treatment of antibiotic contaminants.

Rice wine is a beverage rich in flavor, but the flavor difference caused by rice raw materials has received little attention. To determine the key aroma compounds in rice wine, four types of samples were analyzed by gas chromatography–mass spectrometry (GC–MS), gas chromatography–olfactometry (GC-O), and sensory evaluation. Thirty-eight aroma compounds were detected in the experiment, thirteen of which were identified and quantified using the internal standard method. Additionally, multivariate statistical analyses such as partial least squares discriminant analysis (PLS-DA) effectively revealed three major differential aroma components in rice wine (VIP value ≥ 1). Furthermore, by correlation analysis, it was found that starch and fat in the raw material properties of glutinous rice were significantly and positively correlated with the main differential volatile aroma components in rice wine (p< 0.05). Combined with principal component analysis (PCA), the selection of glutinous rice varieties associated with starch and lipid characteristics during the rice wine brewing process is conducive to improving the overall quality of rice wine.

Radioactive iodine (I 2 ) is a potential risk to environmental safety and human health. The design of efficient and stable functional materials for I 2 capture remains a challenge. In this work, a simple in-situ impregnation method is used to load Ionic Liquid (IL)-[C 2 mim][Tf 2 N] into the pores of MOF-808, named IL@MOF. IL@MOF exhibit excellent I 2 removal performance (2.61 g/g), which is 1.75 and 21.75 times higher than that of MOF-808 and [C 2 mim][Tf 2 N], respectively. This is attributed to the excellent pore structure of MOF-808 and the abundant heteroatom adsorption sites of IL. After modification with hydrophobic IL, IL@MOF exhibit good adsorption performance in high humidity environment. I 2 is retained within IL@MOF in the forms of I 3 − (85 %) and I 2 (15 %). The formation of I 3 − is attributed to charge transfer between the unsaturated site, the heteroatom (N, O, S, F) adsorption site and I 2 within IL@MOF. In addition, the adsorption sites on the IL@MOF surface and adsorption energy are investigated by Density Functional Theory (DFT). Finally, this study provides ideas and guidance for designing MOF-based composites for the effective immobilization of radioiodine.

For I 2 cathodes, the severe polyiodide shuttling and sluggish reaction kinetics result in unsatisfactory cycling lifespan and rate performance. Herein, a bifunctional electrophilic host is designed by engineering the electron cloud density to effectively anchor electron-rich polyiodides. Three configurations are initially screened through density functional theory simulations, which reveal that Si─O bonds can firmly anchor I 3 − via Si electrophilic centers. Owing to the considerably lower electronegativity of Si (1.90) than that of O (3.44), electrons surrounding Si atoms are strongly drawn toward O atoms, creating Si electrophilic centers. Specifically, I 3 − adsorbed onto Si─O bonds exhibits a favorable orbital configuration with a low energy gap, thereby kinetically enhancing polyiodide conversion. As a proof of concept, SiO 2 nanocrystals embedded in conductive microporous bio-carbon are derived from poplar flowers. The resulting I 2 cathodes demonstrate excellent cycling stability over 110 000 cycles at 4 A g −1 and a high rate performance with a capacity of 123.8 mAh g −1 at 100 C. Furthermore, the I 2 cathode with a loading as high as 36.5 mg cm −2 can also perform well in terms of 127.6 mAh g −1 after 100 cycles. This study presents a new route for the rational design of high-efficiency and sustainable hosts for I 2 cathodes.

The intrinsically low electrical conductivity of elemental iodine and its slow redox kinetics represent two significant obstacles that hinder the commercialization of aqueous zinc-iodine batteries. These challenges can be addressed by modulating the adsorption-desorption equilibrium of iodide ions in the active material. This study presented a synergistic strategy of “Electronic Modulation” and “Phase Transition Engineering” to optimize the catalytic adsorption-desorption dynamics. A dual-designed Fe ions doped VO 2- x heterostructure anchored on reduced graphene oxide (Fe-VO 2- x /rGO) is demonstrated to synchronously adjust iodine adsorption and boost redox kinetics. The Fe-induced electronic structure modulation elevated the d-band center of vanadium, creating catalytic sites to promote the desorption of iodide ions and facilitate their diffusion. Concurrently, the phase transition from VO 2- x to V 2 O 5- n within the heterostructure establishes a 3D conductive network, synergizing with rGO to ensure rapid ion/electron transport. This “adsorption-catalysis-transport” collaborative mechanism enabled the Fe-VO 2- x /rGO cathode to achieve an ultrahigh capacity retention of 81.48% after 60,000 cycles at 20 A g −1 , surpassing state-of-the-art zinc-iodine systems. The work provides a paradigm for manipulating interfacial dynamics through electronic and crystallographic dual regulation in conversion-type batteries.

Here we pioneer the design of a nitrogen-rich covalent organic framework (Tph-Pa) with a special α-diimine structure for the effective capture of organic iodine. Tph-Pa, consisting of pyridine-2,5-dicarboxaldehyde and 5,10,15,20-Tetrakis(4-aminophenyl)porphyrin, exhibits abundant nucleophilic N sites for interactions including α-diimine, imine and porphyrin to interact with iodine, and achieves an impressive static adsorption capacity of 1.66 g g −1 for CH 3 I. Furthermore, the adsorption of CH 3 I on Tph-Pa is predominantly controlled by electron density of N sites (α-diimine > imine > porphyrin), which efficiently facilitates the chemical N-methylation adsorption of CH 3 I. This work highlights the exceptional iodine capture capability of α-diimine-functionalized COFs.

High energy density, intrinsic safety, and eco-friendliness of aqueous zinc‑iodine (Zn I 2 ) batteries are hindered by the shuttle effect and sluggish iodine redox kinetics. These limitations result in the formation of highly soluble triiodide ( I 3 − ) intermediates, which adversely affect energy density and cycle life. To address these issues, we designed N, O co-doped porous carbon with interconnected microchannels (N/O-PC) to create abundant catalytic sites and a locally strong adsorption microenvironment for the iodine reduction reaction (IRR). The unique structure of N/O-PC facilitates electrolyte penetration and enhances iodine fixation and loading, effectively inhibiting the formation and shuttling of I 3 − . Leveraging this favorable microenvironment, the battery exhibits exceptional cycling stability with a high capacitance retention rate after 65,000 cycles at 10 A g −1 . In situ characterization and theoretical calculations confirm that N/O dopants serve as active centers promoting the chemical immobilization and catalytic conversion of polyiodides. This work integrates physical adsorption and catalytic conversion to construct a host material, offering a novel strategy for developing a powerful Zn I 2 batteries.

As a sustainable and environmentally friendly polymer, starch is widely employed in textile sizing to enhance the weavability of yarns. However, due to the shortcomings of uneven liquid-phase dispersion and weak film-forming, the prospects for most starch applied to the sizing industry are severely limited. Hence, this work cleverly designed an amphiphilic starch utilizing small cationic molecules, hydrophobic reagents, and starch, which not only improved the requirements of film formation and dispersion uniformity of starch but also realized the applicability to yarns with different compositions. The dispersion exhibited a uniform particle size (905–990 nm) with long-lasting dispersion stability (7 days). Films with favorable film-forming exhibited outstanding mechanical properties with 72.72 MPa of breaking strength and 4.86% of breaking elongation and a hydrophilic effect (water contact angle of 45°), which facilitated the smooth production of the modified yarns. The breaking strength and abrasion resistance of modified cotton yarn were enhanced by 77.4% and 317%, respectively, and the hairiness index of the yarn was decreased by 85.7%. Furthermore, the performances of the modified blended yarn also achieved a marked improvement in relation to the original yarns. Consequently, the amphiphilic starch constructed in this work possesses the sustainable potential to meet the sizing requirements for different yarns.

Metal-organic framework membranes have been proven to possess outstanding iodine adsorption capacity, but many MOFs are highly sensitive to water, limiting their use in aqueous solution. Herein, polypyrrole (PPy) molecules are deposited onto Zn-based metal-organic framework (Zn-MOF) membranes to enhance water stability and the adsorption performance for iodine ions in aqueous solution. The hydrophobic nature of PPy molecules and the nitrogen atoms in the pyrrole ring, which have lone electron pairs, allow for the doping of iodine to form a charge-transfer complex. This effectively slows down the hydrolysis of the Zn-MOF and improves the iodine scavenging ability. For the iodine aqueous solution (I 2 /KI), the saturated capacity of iodine adsorption of the Zn-MOF@PPy membrane reaches up to 397 mg/g, compared to that of the Zn-MOF membrane (183 mg/g). Under dynamic adsorption processes, the Zn-MOF@PPy membrane achieved a removal efficiency of 93.89 % within 6 min. Molecular simulations reveal that Zn-MOF exhibits a water molecule binding energy of -4.6 kcal/mol, while Zn-MOF@PPy shows a weaker binding energy of -1.3 kcal/mol. Based on the Monte Carlo simulations, the atomic distance between I 3 - and Zn-MOF@PPy is 2.8 Å, representing a reduction compared to that of Zn-MOF (4.3 Å). The Zn-MOF and Zn-MOF@PPy have binding energies of -3.4 kcal/mol and -4.6 kcal/mol with I 3 - , respectively. Those results confirm that the hydrophobic PPy layer effectively repels water molecules, creating a low-dielectric environment that substantially mitigates direct water attack on the Zn-MOF framework. The presence of strong interaction sites in the PPy modified layer, which tightly anchors the iodine species on the framework surface. This attempt provides new insights into improving the MOF adsorption membranes’ capture performance and water stability for iodine in aqueous solution.
