In this study, β-cyclodextrin-coated CoFe₂O₄ (CoFe₂O₄@BCD) nanoparticles were synthesized and characterized to assess their efficacy in enhancing the adsorption of Coomassie Brilliant Blue dye. The nanoparticles exhibited an average size of 14 nm and a magnetic saturation of 48.53 A·m²/kg. Rapid adsorption kinetics were observed, with 87% of the dye removed within the first 3 minutes and saturation achieved within 5 minutes, corresponding to a maximum adsorption capacity of 175 mg/g. The adsorption process conformed to a pseudo-second-order kinetic model (R² = 1), and remained stable under varying pH, temperature, and saline/glucose conditions, although minor fluctuations in adsorption capacity were noted. Regeneration tests showed that the CoFe₂O₄@BCD nanoparticles retained their performance over five cycles. Cytotoxicity assays on the A549 human alveolar adenocarcinoma cell line confirmed their biocompatibility. With their rapid, high-capacity adsorption, magnetic properties, and biocompatibility, CoFe₂O₄@BCD nanoparticles offer significant potential for future water remediation applications. © 2024, The Authors.

This research uses Molecular Dynamics (MD) simulations to explore the structural properties and feed transportation behaviors of Ionic Liquid-Polydimethylsiloxane (IL-PDMS) membranes in the pervaporation process. The effects of concentration, temperature, and surface area on IL-PDMS membranes and the Fractional Free Volume (FFV) and Mean-Squared Displacement (MSD) are examined. Additionally, the glass transition temperatures (Tg's) are explored through the construction of a specialized IL-PDMS unit cell. The simulated Tg value of a pure PDMS is 150 K, which aligns with previous studies, validating the method's accuracy and highlighting its potential application for investigating the glass transition of various polymers. By analyzing feed movement, including ethanol/water trajectories, MSD, and diffusivity at different temperatures, the diffusion mechanism within the IL-PDMS membrane matrix is elucidated. An increment in the operational temperature enhances the chain mobility of the polymer and enlarges the membrane's free volume. Notably, water molecules exhibit higher mobility due to their smaller size and less attraction to PDMS, resulting in a small transfer hindrance compared to ethanol. Consequently, ethanol demonstrates a greater preference for concentrating within the IL-PDMS membrane from ethanol/water mixtures. The findings demonstrate the efficacy of MD simulations in analyzing the performance of IL-PDMS membranes during pervaporation separation. This approach offers valuable insights into membrane behavior and holds promise for advancing membrane-based processes. © 2023, The Authors. All rights reserved.

Metal–organic frameworks (MOFs) are ideal adsorbents because of their porous structure, ultra-large specific surface area, abundant active sites, and specific surface charge. Recently, light-response MOFs have received considerable research interests regarding their potential applications in environmental remediation, medical treatment, and artificial intelligence. This review systematically summarizes the recent progress of light-response MOFs and MOF-based composites for light-response adsorption/desorption. The fabrication strategies of light-response MOFs, including in situ synthesis, post-synthesis modification, and introduction of guest molecules, are presented. The mechanisms of light-induced structural change and light-responsive adsorption/desorption are summarized. The prospects for further development of light-response MOFs are discussed. The facile regeneration of light-response MOF-based adsorbents by light irradiation is highly promising for energy saving, environmental friendliness, and sustainability.

China is committed to the sustainable development Agenda and peaking its carbon emissions by 2030. However, interactions between these two agendas and pathways to achieving both remain understudied. This study assesses the sustainability performances and carbon emission patterns of Chinese cities and analyzes their interplay. To measure sustainability, we adopt the Inclusive Wealth Index framework that looks at the productive base of an economy, including produced capital, human capital, and natural capital. The results reveal that several national demonstration zones achieve sustainable peaking in correspondence with declining emissions and increasing sustainability from 2012 to 2019, driven by industrial transformation, education improvement, and renewable resources growth. Comparatively, some northeastern cities mitigate emissions by cutting carbon-intensive industries but fail to develop new sectors to support socioeconomic development, leading to a decline in well-being. Our findings emphasize the need for cities to synergize sustainable development and carbon-peaking pathways while tailoring strategies to local contexts. © 2025 The Author(s)

This article presents the direct torque control (DTC) strategy for the doubly fed induction motor (DFIM) connected to two three-level voltage source inverters (3LVSIs) with neutral point clamped (NPC) structure. This control method allows to reduce the torque and flux ripples as well as to optimize the total harmonic distortion (THD) of motor currents. The use of 3LVSI increases the number of generated voltage, which allows improving the quality of its waveform and thus improves the DTC strategy. The system modeling and control are implemented in Matlab/Simulink environment. The analysis of simulation results shows the better performances of this control, especially in terms of torque and flux behavior, compared to conventional DTC.

This study aims to analyze the incorporation of widely available, cheap and biobased waste material such as wood charcoal which is used as filler in natural fiber reinforced polymer composites. Jute woven fabric (1 × 1 plain weave) was used as a natural fiber reinforcement, unsaturated polyester resin was used as matrix material, and wood charcoal powder used as bio-filler to manufacture various composite material formulations of 25% fiber weight fraction. The wood charcoal filler loadings were 4, 8, 12, 16 and 20 wt% in the polymer matrix of the composites. The developed composite formulations were tested in terms of mechanical and physicochemical properties. Improved tensile properties were revealed with a 4 wt% filler modification, compared to the reference (unmodified) polymer composite. Nonetheless, further increase of filler (8–20 wt%), led to lower mechanical properties. Thermogravimetric analysis showed increased thermal stability of the 4 wt% charcoal filler modified composite compared to the reference one.

While the 17 United Nations sustainable development Goals (SDGs) have explicitly called on businesses to contribute, little is known to what extent have the business sectors engaged with the SDGs. Here we benchmarked the engagement of the Fortune Global Top 500 corporations with the SDGs based on publicly available information screened between November 1, 2019, and February 15, 2020. The results revealed that 304 of the 500 corporations had presented relevant content on their websites. However, 32.6% of the corporations tend to match their usual business practices with relevant SDGs instead of implementing new initiatives. Only 22.8% of the corporations developed specific actions or strategies for specific SDGs, and only 0.2% developed methods and tools to evaluate progress. European-headquartered corporations are leading the way to engage with the SDGs, whereas U.S.- and China-headquartered ones fall short. The SDG 8 (Decent Work and Economic Growth) and SDG 13 (Climate Action) are the most popular SDGs among these corporations. At the same time, SDG 2 (Zero Hunger) and SDG 14 (Life below Water) received the slightest interest. The level of engagement is uneven across various business sectors, with the corporations in the Information & technology sector have largely engaged with the SDGs. In contrast, the Health Care sector has shown the slightest interest in the SDGs. Our results call for leading corporations in these sectors for continuous and enhanced efforts to help accelerate the global process towards the SDGs. Governments could provocatively encourage and regulate business sectors to engage with the SDGs and disclose uniform data to benchmark the progress towards a sustainable future. © 2022

Accurate real-time traffic forecast is critical for intelligent transportation systems (ITS) and it serves as the cornerstone of various smart mobility applications. Though this research area is dominated by deep learning, recent studies indicate that the accuracy improvement by developing new model structures is becoming marginal. Instead, we envision that the improvement can be achieved by transferring the "forecasting-related knowledge" across cities with different data distributions and network topologies. To this end, this paper aims to propose a novel transferable traffic forecasting framework: Domain Adversarial Spatial-Temporal Network (DastNet). DastNet is pre-trained on multiple source networks and fine-tuned with the target network's traffic data. Specifically, we leverage the graph representation learning and adversarial domain adaptation techniques to learn the domain-invariant node embeddings, which are further incorporated to model the temporal traffic data. To the best of our knowledge, we are the first to employ adversarial multi-domain adaptation for network-wide traffic forecasting problems. DastNet consistently outperforms all state-of-the-art baseline methods on three benchmark datasets. The trained DastNet is applied to Hong Kong's new traffic detectors, and accurate traffic predictions can be delivered immediately (within one day) when the detector is available. Overall, this study suggests an alternative to enhance the traffic forecasting methods and provides practical implications for cities lacking historical traffic data.

Ensuring compliance with legal discharge regulations for total phosphorus (TP) is crucial in wastewater treatment plants (WWTPs), considering the minimization of chemical consumption like poly aluminum chloride (PAC). However, the relationship between actual TP removal and PAC consumption presents numerical complexities, hindering data-driven modeling efforts. This study analyzed daily observations over one-year period in WWTP to assess elasticity and productivity, revealing decoupling and congestion patterns between PAC consumption and TP removal. Binary dependent features were established for modeling. The results highlighted the importance of wastewater inflow and biological treatment features, suggesting PAC reduction to mitigate decoupling and congestion. Thus, insights were obtained for sustainable WWTP operations to sufficiently leverage influent characteristics and utilize biological treatment to minimize chemical dosing. The assessment workflow, incorporating elasticity and productivity considerations, establishes a robust basis for further optimization within a normalized production trajectory in wastewater sector, concurrently lowering resource depletion and enhancing environmental benefits. © 2024, The Authors.

Conventional direct torque control (DTC) is one of the excellent control strategies available to control the torque of the induction machine (IM). However, the low switching frequency of the DTC causes high ripples in the flux and torque that leads to an acoustic noise which degrades the control performances, especially at low speeds. Many direct torque control techniques were appeared to remedy these problems by focusing specifically on the torque and flux. In this paper, a state of the art review of various modern techniques for improving the performance of DTC control is presented. The objective is to make a critical analysis of these methods in terms of ripples reduction, tracking speed, switching loss, algorithm complexity and parameter sensitivity. Further, it is envisaged that the information presented in this review paper will be a valuable gathering of information for academic and industrial researchers.
