Summary: This study investigates the design of a Model Predictive Control (MPC) formulation for polytopic multi-model system representation and applies it to a continuous stirred tank reactor (CSTR) system. The proposed method uses a virtual model-process tuning variable and optimizes the Linear Time Invariant (LTI) prediction sequence based on the LTI vertices of the polytopic system. Discussions are made on the a-priori design procedure, online computational effort, and application difficulties.

Summary: The widespread presence of polycyclic aromatic hydrocarbons (PAHs) in marine sediments has ecological and human health implications. Sediment washing (SW) has been found to be an effective remediation approach for PAH-polluted sediments, but concerns about waste handling remain. This study investigated the biological treatment of a synthetic PAH-polluted SW solution using a continuous-flow stirred-tank reactor. The results showed that a PHE removal efficiency of up to 75-94% was achieved, mainly through biodegradation by a PHE-degrading consortium composed of Proteobacteria, Bacteroidota, and Firmicutes phyla.

Summary: The temperature system of CSTR is characterized by strong nonlinearity and uncertain parameters, making it difficult for the linear PID controller to meet the control requirements. The NPID can improve the control effect of nonlinear controlled objects, but its performance decreases when parameters are uncertain or subject to external interference. To improve the adaptive capability of NPID, the RBF-NPID control algorithm is proposed, utilizing the learning ability of RBF neural network to adjust NPID parameters online and improve control performance. Simulation results in MATLAB show the effectiveness and superiority of the proposed algorithm.

Summary: This paper presents an adaptive neural network control method to stabilize a continuous stirred tank reactor (CSTR) under unknown time-varying delays and full state constraints. The use of Lyapunov-Krasovskii functionals in the adaptive controller design deals with time-varying delays effectively, and ensures convergence of tracking error without violating constraints.

Summary: This study focused on the semihydrogenation of acetylene in an ethylene-rich stream using two alloyed Pt catalysts PtCu and PtCo. The PtCu catalyst showed higher activity and ethylene yield compared to PtCo due to its higher unoccupied Pt d-orbital density. This indicates that alloying Pt with Cu is more promising for industrial relevant SHA catalyst.

Summary: This work presents a continuous solvent extraction method for the separation of cobalt and nickel in a millifluidic system using Cyphos IL 101 (C101) as the extractant. The optimal conditions for extraction performance and solvent properties were determined by investigating the effects of channel length, flow rate, and temperature. The performance of a developed manifold structure was compared to a single-channel system, and excellent separation results were achieved. The continuous separation process using the manifold structure resulted in high purity cobalt and nickel products.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
