As a major carbon resource, carbon dioxide recycling can effectively address issues of the greenhouse effect and carbon resource shortages. Carbon dioxide based polypropylene carbonate (PPC) is a polymer material produced from carbon dioxide and propylene oxide, with advantages in environmental protection and sustainability. However, its relatively low thermal stability severely limits its application prospects. In this study, a novel cellulose acetate grafted carbon dioxide based polypropylene carbonate (CA-DMC-CO 2 ) ultrafiltration membrane was prepared by epoxidation and high-pressure catalysis of cellulose acetate side chains. The molecular weight of CA-DMC-CO 2 was 428,169 Da, and its thermal decomposition temperature reached 365 °C. The introduction of polycarbonate side chains endowed the CA-DMC-CO 2 ultrafiltration membrane with good hydrophilicity and excellent permeability, reaching 115.9 L/m 2 h, which performed better than the CA ultrafiltration membrane. In addition, good hydrophilicity of CA-DMC-CO 2 provided effective anti-fouling performance. This study highlights the potential for developing environmentally friendly and sustainable ultrafiltration membranes for practical applications.

Breast cancer stands as the most prevalent type of cancer globally and the leading cause of cancer-related deaths among women. Owing to the substantial side effects associated with conventional treatments such as chemotherapy and radiotherapy, drug delivery systems have been proposed to co-deliver drugs with varying physicochemical properties to tumor cells, thereby achieving a synergistic therapeutic effect. Herein, we designed novel liposomes by membrane hydration method to co-deliver crocetin (CRO) and the chemotherapeutic drug docetaxel (DTX) for the treatment of breast cancer in order to potentiate the efficacy of chemotherapy. The prepared DTX-CRO liposomes (DTX-CRO-Lip) were characterized by transmission electron microscopy (TEM) and dynamic light scattering analysis. DTX-CRO-Lip showed homogeneous spherical morphology and the mean particle size of 75.35 ± 0.52 nm, polydispersity index of 0.26 ± 0.01, and zeta potential of -0.16 ± 0.19 mV. The in vitro drug release study and MTT assays showed that DTX-CRO-Lip had sustained drug release effects and synergistic antitumor effect. The in vivo antitumor efficacy was verified on 4T1 tumor-bearing mice. DTX-CRO-Lip showed the best antitumor efficacy and no apparent side effects, suggesting that it is a promising drug delivery system for the synergistic treatment of breast cancer.

Polycyclic aromatic hydrocarbons and zinc oxide nanoparticles are ubiquitous pollutants in the environment. However, little information is available about their toxicity interaction in food crops. In this study, seed germination and hydroponic experiments were conducted to assess the impact of ZnO (NPs and bulk at 250, 500 and 1000 mg L −1 ) individual and combined with phenanthrene (1 mg L −1 ) on wheat growth for 15 days. Under ZnO (NPs and bulk) alone and combined with phenanthrene exposure, dose-dependent toxicity in some indexes (germination rate, biomass, shoot height, root length) was observed. Both ZnO NPs and bulk inhibited plant growth at high concentrations, but no significant difference was observed between them ( P > 0.05). The chlorophyll concentration of wheat leaves decreased by 0.43–0.60 fold when the levels of ZnO NPs and bulk treated were elevated. There was a negative correlation between ZnO (NPs and bulk) and total chlorophyll. Hill reaction activity also exhibited the same tendency. Through transmission electron microscopy , ZnO NPs were found in wheat seedling root apoplast and symplasm at 1000 mg L −1 with or without phenanthrene. High doses (500 and 1000 mg L −1 ) of ZnO (NPs and bulk) caused more DNA damage to wheat seedling root cells, and ZnO NPs induced stronger genotoxicity than bulk ones to wheat root cells. Superoxide dismutase (SOD) and catalase (CAT) activities of wheat seedling roots decreased at 1000 mg L −1 ZnO (NPs and bulk), especially in the co-exposure treatments. Hence, ZnO (NPs and bulk) combined with phenanthrene cause more damage to wheat seedling roots, and even destroy the antioxidant system. Our findings are helpful for not only assessing the individual and combined toxicity between phenanthrene and ZnO (NPs and bulk), but also for understanding the different response of plants to individual and combined pollution.

(Nb 0.5 Ga 0.5 ) x Ti 1−x O 2 (x = 0.05%,0.2%,0.5%,1%,5%) single crystals were prepared by Verneuil method. Even if the doping amount is 0.05%, the dielectric permittivity (ε′) is obviously higher than that of pure rutile TiO 2 (260), reaching more than 10 4 . As the doping amount x increase, the ε′ increases, and reaches the maximum value when x = 5%, but the dielectric loss increases correspondingly. The best dielectric performance (ε′=1.0 ×10 5 , tanδ=0.034 under 1 kHz) is obtained when the doping amount is 0.5%. Even at 10 6 Hz, the dielectric loss is only 0.019, much lower than the reported ceramic samples. This may be due to the fact crystalline materials can effectively reduce defects such as grain boundary, second phase, porosity and segregation. The dielectric spectra, impedance analysis, XPS and DC bias results show that the colossal permittivity (CP) properties could be attributed to EPDD polarization. With the increase of doping concentration (>1%), the hopping polarization occurs, resulting in a slight increase in dielectric loss. These results indicate that TiO 2 crystal materials with lower dielectric loss are good candidates for dielectric materials. Taking TiO 2 crystal as the research object, we can have a clearer understanding of the origin of TiO 2 dielectric properties and the influence of doping ion content, which is of great significance to the development of TiO 2 -based dielectric materials.

In order to investigate the role of the lignin in the co-pyrolysis process of the sludge and the cellulose, the co-pyrolysis process was carried out in a thermogravimetry analyzer. The result shows that when the proportion of the sludge:cellulose:lignin was 1:1:0.4, the main co-pyrolysis temperature range was narrower, the ultimate pyrolysis weight loss was more, and the synergistic effect had a longer duration time. When the pyrolysis temperature was below 400°C, the addition of the lignin could promote the co-pyrolysis process of the cellulose and the sludge, such as the decrease of the activation energy E.

CuBr 2 serves as a dual-functional additive to realize anion-cation co-passivation for perovskite defects. • CuBr 2 modification boosts crystallinity, increases grain size, and suppresses non-radiative recombination in perovskite films. • The optimized device yields enhanced efficiency, reduced hysteresis, and improved stability. Perovskite solar cells (PSCs) are a promising photovoltaic technology, characterized by high efficiency, low cost, and simple solution fabrication. However, the defects at grain boundaries impair optoelectronic performance and degrade long-term operational stability of PSCs. Herein, CuBr 2 additive was incorporated into the perovskite precursor solution, enabling Cu 2+ and Br⁻ to co-passivate iodine vacancies and uncoordinated Pb 2+ . The CuBr 2 -mediated perovskite films demonstrated the optimized crystallinity, facilitated interfacial carrier transportation, and diminished trap concentration. The PSCs achieved an improved efficiency from 18.53% to 20.10% and demonstrated significantly improved long-term environmental stability. This work provides a novel strategy for anion-cation co-passivation of defects in PSCs.

Achieving high CO selectivity in integrated carbon capture and hydrogenation (ICCH) remains a challenge because Ni-based dual functional materials (DFMs) inevitably catalyze competing methanation. Here, we demonstrate that trace chloride incorporation into Ni–Ca DFMs switches the dominant hydrogenation pathway from methanation to the reverse water−gas shift reaction. Chloride preferentially interacts with the CaO sorbent phase, forming Ca–Cl species that drive CaO densification and substantially lower the reducibility of the adjacent Ni active sites. Consequently, the 1% Cl-modified DFM attains 91.6% CO selectivity at 600 °C, in contrast to the 20.5% CO selectivity of the Cl-free counterpart. Cyclic testing confirms that the Cl-modified DFM maintains stable CO2 conversion and high CO selectivity. In situ experiments further show that chloride suppresses the deep hydrogenation of formate intermediates, thereby terminating the reaction at the CO-forming step rather than proceeding to CH4. This study establishes halogen engineering as an effective and operationally simple strategy for steering product selectivity in ICCH processes.

A Ru nanocluster-coupled Co/Co 2 P heterostructure was rationally designed. • Ru nanoclusters regulate interfacial electrons and catalytic active centers. • Electronic modulation optimizes H* adsorption and accelerates water dissociation. • Hierarchical porous carbon improves mass transport and active-site accessibility. • The catalyst delivers excellent HER activity and overall water splitting. Achieving sustainable hydrogen production via water electrolysis relies heavily on the availability of efficient, stable, and economically viable electrocatalytic systems. Herein, we report a Ru nanocluster-regulated Co/Co 2 P heterostructure catalyst confined within a nitrogen-doped hierarchical porous carbon framework via an ion-exchange-assisted chemical vapor deposition strategy. The synergistic interaction among Ru nanoclusters and Co/Co 2 P heterointerfaces induces interfacial charge redistribution and modulates the electronic structure of the catalytic active sites, thereby facilitating the HER process. Combined experimental analyses and density functional theory calculations reveal that Ru nanoclusters effectively regulate hydrogen adsorption behavior, accelerate water dissociation kinetics, and reduce the Gibbs free Gibbs free-energy change of alkaline HER. Benefiting from the synergistic effects of heterointerface engineering, nanocluster regulation, and hierarchical porous architecture, the resultant optimized catalyst delivers a current density of 10 mA cm −2 at an ultralow overpotential as low as 40 mV, coupled with remarkable long-term cycling stability. Moreover, the Co-Co 2 P@Ru@NC||RuO 2 electrolyzer delivers a low cell voltage of 1.52 V at 10 mA cm −2 , demonstrating its potential for efficient overall water splitting. This work provides a rational strategy for constructing advanced electrocatalysts through synergistic electronic modulation and interface engineering toward sustainable hydrogen production.

Nitrogen-rich carbon dots loading with transition metals have received tremendous attention during the last decade due to superior catalytic performance in toxic pollutants degradation. The cobalt-doped carbon dots (Co-CDs) with high content of pyrrolic N have been synthesized in formamide solution via one-step solvothermal method. The pyrrolic N offers binding sites for the cobalt ions, forming Co N bond which facilitates the peroxymonosulfate (PMS) adsorption. It was found that the degradation in the Co-CDs/PMS system was dominated by high-valent cobalt-oxo species (Co IV =O) through a nonradical pathway. The simulation reveals that the formation of Co IV O species is favored by cleavage of the Co N bond and electron transfer from Co atom to O atom in the PMS. This study provides a deep understanding of PMS activation by carbon dots, and inspires rational design of environmental catalysts.

Steel slag-derived CaO-based composites were designed for high-performance heat storage. • Fe Mn co-modified composites retained 97% heat storage density after 20 cycles. • Fe Mn co-modification enhanced solar absorptance (82%) and compressive strength (1.26 N). • Fe Mn coexistence promoted oxygen vacancies and accelerated CO 2 uptake. CaO-based thermochemical energy storage (TCES) materials have attracted wide attention due to their high energy density, favorable reaction reversibility, and potential integration with CO 2 capture. Steel slag, as a Ca-rich solid waste naturally containing Fe and Mn, offers intrinsic advantages for developing structurally stable and solar-absorptive heat storage materials. However, current steel slag-derived TCES materials still suffer from limited understanding of the functional role of inherent transition-metal elements during repeated high-temperature cycling. In this work, Fe/Mn modified steel slag-derived CaO-based composites were rationally designed to clarify the individual and synergistic effects of Fe and Mn during high-temperature cycling. Fe/Mn containing phases formed a stable framework among CaO particles, effectively suppressing grain sintering and pore collapse. The Fe Mn co-modified sample exhibited superior overall performance. After 20 cycles, Fe Mn co-modified composite maintained a heat storage density of 1263 kJ/kg, corresponding to 97% retention of its initial capacity. The Fe Mn co-modified composite achieved a solar absorptance of 82% and a crushing strength of 1.26 N, which were 1.2 and 4.1 times higher than those of the unmodified sample, respectively. Moreover, the coexistence of Fe and Mn promoted electron transfer and oxygen vacancy formation through double-exchange interactions, thereby facilitating the carbonation reaction. This study demonstrates a targeted Fe Mn co-modification strategy based on the intrinsic Fe-rich feature of steel slag and provides new insights into the high-value utilization of steel slag for sustainable and durable TCES materials.

To address the issues of energy depletion and environmental pollution caused by the combustion of fossil fuels, electrocatalytic overall water splitting for hydrogen production is one of the very promising approaches. The key to the large-scale application of electrocatalytic overall water splitting lies in the search for low-cost, high-content, and high-performance electrocatalysts. In this paper, through a two-step process of carbonization followed by phosphination, the P-modified Co2C@Co/NF composite material (P–Co2C@Co/NF) was successfully designed and synthesized. P–Co2C@Co/NF exhibits excellent performance in hydrogen evolution reactions (HER) and oxygen evolution reactions (OER). Under alkaline conditions, the overpotential for HER and OER can reach 10 mA cm–2 current density with only 75 mV and 246 mV respectively. P–Co2C@Co/NF demonstrates excellent overall water splitting capability, requiring only 1.63 V of driving voltage to achieve 10 current density. This provides a new method for enhancing the electrocatalytic performance of heteroatom-modified transition metal compounds.
