Facile Construction Engineering of Pr6O11@C with Efficient Photocatalytic Activity.

In this study, facile construction engineering of Pr6O11@C with efficient photocatalytic activity was established. Taking advantage of the flocculation of Pr3+ in the base medium, acid red 14 (AR14) was flocculated together with Pr(OH)3 precipitate, in which Pr(OH)3 and AR14 mixed highly uniformly. Calcinated at high temperature in N2, a novel Pr6O11@C was successfully synthesized. The resulting materials were characterized by XRD, SEM, FT-IR, Raman, and XPS techniques. The results show that the cubic Pr6O11@C with Fm3m space group, similar to that of Pr6O11, was obtained. From the results of the photodegradation of AR14, it is found that the photocatalytic efficiency of Pr6O11@C is higher than that of pure Pr6O11 due to the formation of abundant carbon bonds and oxygen vacancies. Compared with pure Pr6O11 and other carbon-based composites, the acid resistance of Pr6O11@C is greatly improved due to the highly uniform dispersion of Pr6O11 and C, which lays a solid foundation for the practical application of Pr6O11@C. Moreover, the role of NH3·H2O and NaOH used as precipitants for the photocatalytic efficiency of Pr6O11 was investigated in detail.

3D porous PEDOT/MXene scaffold toward high-performance supercapacitors

3D architectures of conductive polymer, especially PEDOT hold great promise in energy storage and conversion fields. However, the facile construction of 3D PEDOT and its functionalization have still been challenges due to its poor processability. Herein, the fabrication of 3D porous PEDOT:PSS and its functionalization with MXene are realized synchronously through a simple and low-cost self-assembly process. The prominent capacitive performance of MXene, excellent chemical stability of PEDOT:PSS and 3D porous architecture with inhibited aggregation of MXene nanosheets, large amount of active sites, and electrolyte storage chamber endow the PEDOT/MXene-based porous structure with superior capacitive performance than individual PEDOT:PSS or MXene porous and flat structures. Furthermore, the PEDOT/MXene-based porous structure can be applied as a flexible scaffold for the deposition of conductive polymer to construct excellent electrodes for supercapacitors (SCs). When polypyrrole (PPy) is deposited, the prepared porous PEDOT:PSS/MXene/PPy electrode exhibits a high gravimetric specific capacitance of 345 F g−1 at a current density of 0.5 A g−1 and a remarkable capacitance retention of 89 % over 5000 cycles. Based on it, an asymmetric supercapacitor (ASC) with a high energy density of 56.34 Wh kg−1 at the power density of 120 W kg−1, and a capacitance retention of 75 % after 5000 cycles is developed. Besides, the porous PEDOT:PSS/MXene/PPy can be constructed on various substrates in any pattern with high design freedom, thus enabling customizable electrochemical performance. When constructing on a flexible substrate, excellent deformation-tolerant performance is shown. This work provides a high-performance electrode for SCs, as well as a universal route for the construction and functionalization of 3D PEDOT-based structures.

Scale-up of plug-flow reactors in anaerobic treatment of agro-industrial wastes

This study is aiming to evaluate the optimization potential of anaerobic digestion systems for the treatment of complex agro-industrial wastes at an industrial scale. In previous work, the performance of a 20 L pilot-scale Plug Flow Reactor (PFR) that was able to operate at Organic Loading Rates (OLRs) of up to 25 kg Chemical Oxygen Demand (COD) m−3 d−1, was demonstrated. This concept was then successfully transferred in a semi-industrial scale PFR of a volume equal to 50 m3, and the optimal operational parameters were evaluated. The construction of a full industrial scale facility followed, utilizing initially a 380 m3 PFR. Since PFR systems in practice do not behave ideally, due to short Length to Diameter ratio (L/D) and/or higher axial dispersion, the ideal PFR behavior was compared with real data of the non-ideal industrial-scale system; a performance reduction of 25–30 % was detected. However, the disadvantage of the non-ideal behavior of PFRs can be overcome by the cascaded arrangement of two such reactors (2 × 380 m3 PFRs), leading to a total volume reduction of 35 %, as depicted by experimentation on the industrial scale cascaded PFRs. The optimal design parameters for the PFRs are provided.

Facile construction of a bifunctional Eu-MOF for selective fluorescence sensing and visible light photocatalysis of tetracycline

Contamination detection and removal are important steps in environmental monitoring and cleanup. In this study, europium metal-organic framework structures (Eu-MOF) were designed and prepared that can act as fluorescent probes and photocatalysts for the detection and removal of tetracycline (TC) antibiotics. Eu-MOF was generated by a one-step solvothermal method using europium ion as the metal ion and terephthalic acid as the organic ligand source. The red fluorescence of Eu-MOF is selectively enhanced by TC due to the antenna effect. Eu-MOF, which has a linear range of 0.5–60 μM, can be utilized as a fluorescent probe for tetracycline detection based on this phenomena. In particular, Eu-MOF was found to be able to effectively photocatalyze the degradation of TC, with tetracycline removal rates of about 70 % and 55 % after 180 min of irradiation under ultraviolet light (UV) light and simulated visible light, respectively. The photocatalytic ability of Eu-MOF originated from the generation of hydroxyl radicals (•OH), superoxide radicals (•O2−) and electron holes (h+) under light irradiation. This study innovatively proposed a bifunctional Eu-MOF for TC fluorescence detection and photocatalytic degradation, which provides a novel method for the quick and easy identification and elimination of pharmaceutical contaminants. It can also provide some reference value for the construction of ratiometric fluorescent probes and heterojunction photocatalysts and their application in the treatment of water pollution.

Innovative strategy for the facile construction of active multifunctional coating on inert thermal insulation surface

Ethylene propylene diene monomer rubber is highly attractive as a thermal insulation material for solid rocket motors but is plagued by its inherent low wettability. Existing methods have been used to solve this problem by manually or mechanically sanding the surface, which is environmentally hazardous. Herein, a multifunctional composite coating is constructed on the surface of inert thermal insulation materials using a two-step low temperature plasma surface treatment via an efficient hydrogen-bonding assembly strategy. The resultant composite coating exhibits excellent adhesion to the inert thermal insulation substrate. Benefitting from this, the coating retained its superhydrophilicity after 80 abrasion cycles and 12 h of agitation scrubbing with saturated salt water. Due to the superhydrophilicity of the coating, a self-cleaning effect for oils of different viscosities on the surface can be achieved by the simple action of water. Besides the adiabatic performance tests showed that the average top surface temperature of the coated thermal insulation was 30.9 °C lower than that of the original thermal insulation. Char residue analysis showed that the coating formed a more complete char layer at high temperatures, resulting in improved adiabatic performance. Our work would afford a new frontier to fabricate solid rocket motor thermal insulation materials with excellent surface comprehensive properties in a simple, eco-friendly and sustainable way, opening new possibilities for the advancement of high-performance inert materials.

Assessment of Rural Industry Integration Development, Spatiotemporal Evolution Characteristics, and Regional Disparities in Ethnic Regions: A Case Study of Inner Mongolia Autonomous Region Counties

Ethnic regions in China primarily focus on the development of agricultural and animal husbandry economies, which are relatively underdeveloped. Rural industry integration development (RIID) is considered the foundation and guarantee for ethnic regions to achieve high-quality modernization of agriculture. The purpose of this article is to measure the level of rural industrial integration in ethnic minority areas, analyze the spatial evolution and regional differences, and explore the actual situation of RIID in these regions. The aim is to provide a decision-making basis for local governments to effectively promote the development of rural industrial integration. Based on the improvement of the evaluation index system for rural industrial integration development, this paper takes the counties of the Inner Mongolia Autonomous Region as the research area. Utilizing panel data from the statistical yearbooks of 68 banners and counties in Inner Mongolia from 2011 to 2020, the panel entropy weight TOPSIS method is employed to assess the average level of rural industrial integration in the research area. The ArcGIS natural breakpoint method is employed to classify the level of RIID in county areas. Exploratory Spatial Data Analysis (ESDA) and GeoDa are utilized to analyze the spatial distribution characteristics of RIID. Finally, the Theil index is employed to analyze the regional differences in the level of RIID. The results show the following: (1) The overall level of RIID in ethnic regions is relatively low, with the contributions of the four dimensions in the evaluation index system as follows: integration path > integration foundation > integration sustainability > integration effect. The level of RIID in the study area is as follows: western region > eastern region > central region. (2) Spatially, there are positive correlations and significant spatial clustering in the level of RIID, with the spatial clustering effect of RIID weakening. (3) There are regional differences in the level of RIID, which are expanding. The inter-regional differences are decreasing, while the intra-regional differences are increasing. (4) The construction of agricultural processing facilities, financial investment, financial support, and talent policies are important influencing factors for the current stage of RIID in ethnic regions. Therefore, in the low-level development stage of RIID in ethnic regions, it is necessary to fully utilize the advantages of resource endowment, increase investment in rural infrastructure, and strengthen the guidance of talent flow into rural revitalization construction.

Polyphenol-Based Bicontinuous Porous Spheres Via Amine-Mediated Polymerization-Induced Fusion Assembly.

Bicontinuous porous materials, which possess 3D interconnected network and pore channels facilitating the mass diffusion to the interior of materials, have demonstrated their promising potentials in a large variety of research fields. However, facile construction of such complex and delicate structures is still challenging. Here, an amine-mediated polymerization-induced fusion assembly strategy is reported for synthesizing polyphenol-based bicontinuous porous spheres with various pore structures. Specifically, the fusion of pore-generating template observed by TEM promotes the development of bicontinuous porous networks that are confirmed by 3D reconstruction. Furthermore, the resultant bicontinuous porous carbon particles after pyrolysis, with a diameter of ≈600nm, a high accessible surface area of 359m2g-1, and a large pore size of 40-150nm manifest enhanced performance toward the catalytic degradation of sulfamethazine in water decontamination. The present study expands the toolbox of interfacial tension-solvent-dependent porous spheres while providing new insight into their structure-property relationships.

Assessment of the Local Impact of Retention Reservoirs—A Case Study of Jagodno (Existing) and Sarny (Planned) Reservoirs Located in Poland

Facile Construction of a Double-Heterojunction Perovskite Quantum Dot System for Efficient Photocatalytic Cr6+ Reduction.

Based on their excellent stability, high carrier mobility, and wide photoresponse range, composites formed by embedding perovskite quantum dots (PQDs) into metal-organic frameworks (PQDs@MOF) show great development potential in the field of photocatalysis, including the toxic hexavalent chromium (Cr6+) degradation, CO2 reduction, H2 production, etc. However, the rapid recombination of photogenerated carriers is still a major obstacle to the improvement of photocatalytic performance, and the internal mechanism of photocatalysis is still unclear. In this work, we construct a novel double heterojunction photocatalyst by encapsulating CsPbBr3 PQDs in Zr-based metal-organic frameworks (UiO-67) and loading additional hole-acceptor pentylenetetrazol (PTZ). Spontaneous photoinduced charge-transfer and separation between interfaces are confirmed by time-resolved photoluminescence and transient absorption spectroscopy. Furthermore, compared with pure UiO-67, the photoactivity of CsPbBr3 PQDs@UiO-67@PTZ increased 3-fold due to the long-lived charge-separated state. Our findings provide a new guideline for the design of PQDs@MOF-based photocatalysts with long-lived photogenerated carriers and outstanding photocatalytic activity.

Hygienic assessment of the carcinogenic risk to the health of the population of the industrial district of Samara due to atmospheric air pollution

The article presents the results of a study assessing the possible risks of the population living in one of the districts of the city of Samara. The object of the study is the Kuibyshev district of Samara. The high anthropogenic load of the district is formed by enterprises of the oil refining and petrochemical industries, enterprises for the production of metal structures, sewage treatment plants, construction facilities, as well as intensive traffic flow. The initial information for assessing public health risks was the data obtained during the analysis of ambient air samples, as well as the results of calculations of the dispersion of pollutant emissions to nearby territories from the leading industrial enterprises of the district and mobile sources. The research was carried out in several stages. At the first stage, we identified the main sources of ambient air pollution, took into account the terrain, wind directions, and the nature of pulse operation of a number of leading sources. At the second stage, 6234 studies of ambient air samples taken in the Kuibyshev district of Samara, were conducted, priority substances were identified, and carcinogenic hazard indices (HRIc) were calculated. The data obtained indicate that the risks to public health are primarily formed as a result of atmospheric pollution with substances such as nitrogen dioxide, sulfuric acid, sulfur dioxide, a mixture of hydrocarbons, hydrogen sulfide, benzene. The main pollutants forming the level of the total carcinogenic risk to the health of the Samara population are hexavalent chromium and benzene. The total carcinogenic risk to the health of the population of the Samara region with a high degree of anthropotechnogenic load during the study period belongs to the 2nd range of reference boundaries and is characterized as acceptable, however, with the simultaneous presence of various pollutants in the air, an unfavorable background of combined effects on the body is created, which can lead to the formation of a certain pathology in the population.

Facile construction of recyclable heat‐resistant polymers via alkaline‐induced cation‐π cross‐linking

AbstractThe cation‐π cross‐linked heat‐resistant K‐poly(N‐aryleneindole sulphone) PINSU film, which has a high glass transition temperature (Tg = 268°C) and a decomposition temperature (Td = 547°C), was prepared by soaking PINSU film in alkaline aqueous solutions. Compared with the linear polymer PINSU, the Tg and Td of the K‐PINSU were significantly enhanced. The dynamic cation‐π cross‐linking can be reversibly removed and reconstructed driven by external stimulations in the polymer network, which endows the cross‐linked K‐PINSU with cyclable behavior and excellent mechanical stability. In addition, we have successfully demonstrated that the Tg of the K‐PINSU can be nondestructively detected by monitoring the changes in fluorescence intensity.

Facile construction of copper-doped metal organic framework as a novel visible light-responsive photocatalyst for contaminant degradation

ABSTRACT Metal–organic frameworks (MOFs) with photocatalytic activity have garnered significant attentions in environmental remediation. Herein, copper-doped zeolitic imidazolate framework-7 (Cu-doped ZIF-7) was synthesized rapidly and easily using a microwave-assisted technique. Various analytical and spectroscopic methods were employed to access the framework, morphology, light absorption, photo-electrochemical and photocatalytic performance of the synthesized materials. Compared to ZIF-7, Cu/ZIF-7 (molar ratio of Cu2+ to Zn2+ is 1:1) demonstrates superior visible light absorption ability, narrower band gap, enhanced charge separation capability, and reduced electron–hole recombination performance. Under visible light irradiation, Cu/ZIF-7 serves as a Fenton-like catalyst and demonstrates exceptional activity for contaminant degradation, while virgin ZIF-7 remains inactive. With the addition of 9.8 mmol H2O2 and exposure to visible light for 30 min, 10 mg of Cu/ZIF-7 can completely decompose RhB solution (10 mg/L, 50 mL). The synergistic effect of the Cu/ZIF-7/H2O2/visible light system is attributed to visible light photocatalysis and Fenton-like reactions. Cu/ZIF-7 demonstrates excellent catalytic performance stability, with only a slight decrease in degradation efficiency from an initial 97.0% to 95.4% over four cycles. Additionally, spin-trapping ESR measurements and active species trapping experiments revealed that h+ and ·OH occupied a significant position for Rhodamine B (RhB) degradation. Degradation intermediate products of Rhodamine B have been identified using UPLC-MS, and the degradation pathways have been proposed and discussed. This work offers a facile and efficient technique for developing MOF-based visible light photocatalysts for water purification.

Facile construction of porous carbon fibers from coal pitch for Li-S batteries

Coal pitch, an important by-product in the coal coking industry with a high output, is a low-cost and high-carbon yield precursor for the manufacturing of high-value carbon materials. Herein, N/O co-doped carbon fiber (CFCP), fabricated by electrospinning using pre-oxidized coal pitch as the precursor, was employed as the sulfur host for Li-S batteries. The presence of more pyrrolic N and graphic N in CFCP than carbon fiber made from polyacrylonitrile benefits the adsorption of lithium polysulfide and the battery’s life. Sulphur-CFCP cathode (S@CFCP) exhibited excellent specific capacity and cyclability, with a specific capacity of 701.1 mAh/g and a low capacity decay rate of 0.088% per cycle over 200 cycles at 2.0 C, respectively. The high ion diffusion rate, low charge transfer resistance, and effective conversion of lithium polysulfides enable the high electrochemical performance of S@CFCP.

Stable ionic liquid/Zr-MOF co-modified silica microspheres: Facile construction strategy and promising chromatographic applications

The stability of porous metal-organic frameworks (MOFs) as ideal materials for adsorption and separation has always been a key concern. In this study, an ionic liquid (IL) with excellent properties synthesized under solvent-free conditions was used to modify Zr-MOF@SiO2 for the first time to enhance the stability and improve the separation ability of Zr-MOF@SiO2 for chromatographic applications. The IL serves a dual purpose of supporting the backbone structure of Zr-MOF and acting as a ligand to coordinate with Zr(IV). This facile construction strategy ensures that the overall structural framework of the IL/Zr-MOF composite is more stable. Additionally, the presence of IL with imidazolium and carboxyl groups can facilitate efficient chromatographic separation by providing multiple interaction mechanisms. The results shows that the separation performance of the IL/Zr-MOF composite is significantly superior to that of the original Zr-MOF. Furthermore, the obtained new IL/Zr-MOF@SiO2 column exhibits appreciable stability, repeatability and reproducibility, which also performs well in the analysis of real samples with no significant matrix effects, demonstrating good reliability of the developed method. This study proposes a facile strategy for cleverly synthesizing a novel IL/Zr-MOF@SiO2 as an efficient chromatographic separation material, thereby potentially broadening the application of Zr-MOF in separation science. The facile preparation and promising application of IL/Zr-MOF may also offer a new possibility for employing MOF-based composite materials as effective liquid chromatographic stationary phases.

Multi-Encoder Spatio-Temporal Feature Fusion Network for Electric Vehicle Charging Load Prediction

Electric vehicles (EVs) have been initiated as a preference for decarbonizing road transport. Accurate charging load prediction is essential for the construction of EV charging facilities systematically and for the coordination of EV energy demand with the requisite peak power supply. It is noted that the charging load of EVs exhibits high complexity and randomness due to temporal and spatial uncertainties. Therefore, this paper proposes a SEDformer-based charging road prediction method to capture the spatio-temporal characteristics of charging load data. As a deep learning model, SEDformer comprises multiple encoders and a single decoder. In particular, the proposed model includes a Temporal Encoder Block based on the self-attention mechanism and a Spatial Encoder Block based on the channel attention mechanism with sequence decomposition, followed by an aggregated decoder for information fusion. It is shown that the proposed method outperforms various baseline models on a real-world dataset from Palo Alto, U.S., demonstrating its superiority in addressing spatio-temporal data-driven load forecasting problems.
