Fermentation residue of food waste (FRFW) is rich in degradable organics (e.g., carbohydrates, proteins) that nourish microbial metabolism, offering dual potential as a carbon source supplement and waste valorization strategy. This study focused on the influence mechanisms of sterilized and non-sterilized FRFW on membrane fouling in anaerobic-anoxic-aerobic membrane bioreactor (AAO-MBR) processes for rural wastewater treatment. The results demonstrated that FRFW could synergistically mitigate membrane fouling through multiple pathways. Under non-sterilized and sterilized conditions, FRFW addition reduced transmembrane pressure (5.16 and 3.10 kPa), increased live cell proportion on membrane surfaces (9.15 % and 15.05 %), and decreased polysaccharide content (5.82 % and 1.60 %), while reducing inorganic elements (i.e., Fe and P). Analysis of sludge characteristics revealed that FRFW induced an increase in floc, reduced average fluorescence intensity of polysaccharides in extracellular polymeric substances (EPS), while effectively suppressing soluble microbial products accumulation and inhibiting polysaccharide/humic acid generation in EPS. Finally, FRFW shifted dominant genera on membrane surfaces from Acinetobacter and Pseudomonas to functional taxa including Saccharimonadales and Saprospiraceae. Enhanced negative interactions in co-occurrence networks drove competitive inhibition, while significantly increasing the abundance of membrane fouling control-associated functional bacteria. This study will provide theoretical foundations and technical references for evaluating FRFW's applicability in rural wastewater treatment systems. © 2025 Elsevier B.V.

controlling amine monomer diffusion behavior plays a crucial role in fabricating well-defined architecture and high-performance nanofiltration (NF) membranes through interfacial polymerization. Herein, a zwitterionic liquid hydrogel transition layer was introduced to the sustained-release amine monomer to the regulated interfacial polymerization process to fabricate a high-performance NF membrane. The hydrogel (Gel) was fabricated via in-situ one-step UV photo-initiated free-radical polymerization between 1-vinyl-3-ethylimidazolium chloride ([VEIm][Cl]) and 3-sulfopropyl methacrylate potassium salt (SMP) on PES substrate membrane surface. Then polyamide layer formed on the Gel layer surface under the regulation of mitigating the amine diffusion behavior. Low-field time-domain NMR (LF-NMR) analysis and water-absorbing demonstrated that the Gel-PA membrane showed high water-membrane interaction. Positron annihilation lifetime spectroscopy (PALS) also confirmed the Gel-PA composite membrane possessed enlarged free volume . Membrane surface and cross-sectional SEM morphologies also showed the Gel-PA membrane with a less ridge-and-valley loose structure and thinner thickness. Combined with the uptake ability of the Gel layer, the obtained Gel-PA composite membrane displayed a high permeance of 13.22 L m -2 h -1 bar -1 , a high Na 2 SO 4 rejection of 98.23%, a favorable NaCl/Na 2 SO 4 selectivity of 49.75, and excellent long-term operational stability . This sustained-release strategy provides a facial and feasible approach to controlling the IP process and obtaining high-performance nanofiltration membranes. © 2022, The Authors.

A nonlinear model predictive controller for the anaerobic digestion of readily biodegradable substrates is presented. The controller aims to achieve a planned methane production, following a reference trajectory for the whole operation. Using an existing dynamic model of anaerobic digestion, the controller optimizes the operation conditions by conveniently manipulating a set of process variables such that the methane flow rate follows the reference trajectory. The controller works in a sequential approach, i.e., the plant trajectory is estimated over a prediction horizon with a simplified dynamic model of the process that includes only two biological reactions: acidogenesis and methanogenesis ; then, the model predictions are optimized via a sequential quadratic programming method to match the desired trajectory. Due to the simplicity of the process model, the iterative optimization process is solved in a relatively short time. Both the dynamic model of the process and the optimization algorithm are implemented in MATLAB. The controller is tested in a simulation case study treating a readily biodegradable liquid effluent, where the same process model is used to mimic the measurements of the real plant.

The control performance of the 3-phase grid inverter decides the quality and quantity of power transfer from solar panels to the utility grid. Therefore, performance enhancement of control techniques of grid-tied photovoltaic system has practical significance. The objective of this work is to enhance servo control of the grid-tied PV system using a multi-variable internal model control (IMC) technique. The design guidelines of IMC for the grid-tied photovoltaic system is clearly presented. The filter model of the voltage source inverter is employed to design the IMC. Experimental results are demonstrated for two conditions. In one of the conditions, cascaded control of DC-link capacitor voltage and grid current has been carried out. The current reference for the IMC is generated from the PI controller which controls the capacitor voltage. Maximum power of the PV is tracked by generating suitable reference voltage for the DC-link voltage control. In the other condition, only IMC performance is verified assuming constant DC source. The experimental setup is explained in detail and concluding remarks are presented.

Photocatalysis is considered an economical, environmentally friendly, and effective technology for removing pollutants. The construction of Z-Scheme heterojunctions has been identified as one of the feasible solutions capable of enhancing the photocatalytic activity. Herein, a series of visible light responsive photocatalysts (NiIn2S4/Uio-66 composites) with excellent activity and stability were prepared by using a solvothermal process. It is found that 20 mg L-1 of tetracycline (TC) could be almost completely degraded under visible light irradiation within 1 h, when the mass ratio of NiIn2S4 to Uio-66 is 0.5:1 (NISU-0.5) and the solution pH=11. In addition, after six cycles, the degradation rate of tetracycline photocatalyzed by NISU-0.5 still reach up to 90%. Ultraviolet photoelectron spectra (UPS), X-ray photoelectron spectra (XPS) and electron spin resonance measurements (ESR) confirm the formation of the Z-Scheme heterostructure between NiIn2S4 and Uio-66. The synergistic effect between built-in electric field, energy band bending and coulomb interactions in interface of Z-Scheme heterojunction is conducive to restrain the recombination of photogenerated electrons and holes, which greatly improve the photocatalytic activity. In conclusion, this study offers a new thought for design and synthesis of Z-Scheme heterojunctions and provides a cost-effective strategy for solving environmental pollution and energy problems in the future. © 2022, The Authors.

This paper studies the leaderless consensus problem of heterogeneous multiple networked Euler-Lagrange systems subject to persistent disturbances with unknown constant biases, amplitudes, initial phases and frequencies. The main characteristic of this study is that none of the agents has information of a common reference model or of a common reference trajectory. Therefore, the agents must simultaneously and in a distributed way: achieve consensus to a common reference model (group model);achieve consensus to a common reference trajectory;and reject the unknown disturbances. We show that this is possible via a suitable combination of techniques of distributed 'observers', internal model principle and adaptive regulation. The proposed design generalizes recent results on group model learning, which have been studied for linear agents over undirected networks. In this work, group model learning is achieved for Euler-Lagrange dynamics over directed networks in the presence of persistent unknown disturbances. Copyright © 2021, The Authors.

Photodynamic therapy (PDT) is an emerging noninvasive therapy modality for treating cancer diseases. However, conventional PDT suffers from poor stability of organic photosensitizers, limited tissue penetration depth of excitation light and hypoxic tumor microenvironment, which hinders its modern clinical applications. The combination of PDT and nanotechnology is becoming a promising technology to tackle these troubles. Core-shell structured nanoparticles are of great interest as they can integrate the functionalities of individual components into one structure and exhibit improved physical and chemical properties that are different from the single component. Therefore, many efforts have been paid to develop core–shell structured nanoparticles for PDT of cancer. This review provides a panorama of the latest achievement in the developments of core–shell structured nanoparticles for PDT-based cancer treatment and related imaging. Concretely, this review starts with the categories of core–shell structured nanoparticles, followed by the functions of these nanoparticles in PDT of cancer, including photosensitizer delivery vehicle, energy transducer, photosensitizer and hypoxic tumor microenvironment modulator. Then the applications of core–shell structured particles for photodynamic synergistic therapy of cancer are highlighted as well as their imaging applications as contrast agents. Finally, perspectives on the major challenges and opportunities are presented for better developments in the future research. © 2022 Elsevier B.V.
