Summary: Computational fluid dynamics was used to study the laminar hydrodynamics and heat transfer characteristics of highly viscous fluid in a Sulzer mixer reactor (SMR), which showed better performance in terms of mixing and heat transfer compared to a straight tube heat exchanger (STHE) and a straight tube heat exchanger with segmental baffles (STHE-SG). SMR exhibited more uniform velocity and temperature distributions, as well as a narrower residence time distribution. The regularly arranged heat exchange tubes in SMR helped to continuously twist and split the highly viscous fluid, leading to radial mixing and improved heat transfer efficiency.

Summary: This study simulates the effect of baffles on heterogeneous photocatalytic oxidation of gas-phase ethylene in three annular reactors using computational fluid dynamics. The results show that baffles can improve the uniformity of flow and prolong the residence time, but have little effect on radiation distribution and complex effects on the diffusion of ethylene.

Summary: This study applied computational fluid dynamics to analyze the hydrodynamics, heat transfer, and mixing of highly viscous non-Newtonian fluid in a Sulzer mixer reactor. The study found that increasing the rheological parameters led to higher viscosity and power consumption. The yield stress and power-law index significantly affected shear distribution, residence time distribution, and mixing efficiency. Increasing the inlet velocity improved heat transfer performance and mixing efficiency.

Summary: A membrane-assisted stirred slurry reactor was developed by introducing a membrane tube into a stirred tank, and simulations using Euler-Lagrange method showed good agreement with experimental data on cake mass and particle deposition patterns. The presence of the membrane tube created an asymmetric flow field, with shear stress on the membrane surface directly affecting particle deposition. Increasing impeller speed reduced particle deposition, and positioning the membrane tube close to the impeller decreased cake mass. Upward liquid flow from a pitched-blade impeller resulted in lower shear stress, making a vertical-blade impeller preferable.

Summary: In recent years, there have been numerous numerical studies on scour around offshore pipelines, primarily focusing on two-dimensional setups. This study introduces a numerical tool based on the Ansys FLUENT flow solver to investigate three-dimensional scour around finite length pipelines. The model's accuracy is validated against measurements of both two-dimensional scour around a long pipe and three-dimensional scour around a sphere. Subsequent computations reveal the relationship between scour depth and pipeline length.

Summary: Pre-treatment is crucial in enhancing cellulose accessibility from lignocellulosic biomass like empty fruit bunch. Ozonolysis pre-treatment is a green alternative for isolating cellulose from EFB. A diffusion-reaction model of EFB ozonolysis in a novel reactor was developed, showing larger biomass particles consume more ozone and have faster delignification rates. Computational simulations revealed that larger particles have lower ozone velocity but higher surface concentration.

Summary: Efficient penetration and retention of therapeutic agents in tumor tissues can be achieved through rational design of drug delivery systems. In this study, a polymer-dendron conjugate is proposed, which undergoes a structural transformation triggered by a specific enzyme, leading to the release of therapeutic agents and interaction with tumor cell membranes for deep penetration and prolonged retention in the tumor tissues. Additionally, this conjugate disrupts cell homeostasis, making tumor cells more susceptible to photodynamic therapy.

Summary: Emerging nanomedicines can eliminate cancer cells by promoting excessive intracellular reactive oxygen species (ROS) generation. However, tumor heterogeneity and poor penetration of nanomedicines often result in varying levels of ROS production, where low levels of ROS can actually promote tumor cell growth, reducing the effectiveness of these nanomedicines. In this study, a novel amphiphilic and block polymer-dendron conjugate-derived nanomedicine (GFLG-DP/Lap NPs) was developed, incorporating a photosensitizer (Ppa) for ROS therapy and Lapatinib (Lap) for molecular targeted therapy. By combining ROS therapy with Lap, the synergistic effect effectively kills cancer cells, even in deep tumor regions.

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.

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.
