This article aimed to study the characteristics of chaotic advection and mass transfer of viscous liquid–liquid flows in a novel 3D serpentine microchannel (TSM) with hybrid structures. The TSM and its corresponding experimental setup are established, and the CFD model is verified through flow field visualization experiments. Results reveal that efficient chaotic convection in TSM is achieved through

Noble metal-catalyzed reductive amination of carbonyl compounds using molecular hydrogen is a promising green route for amine synthesis, but a challenge remains to boost the atomic efficiency of noble metal species. Herein, MFI zeolite encapsulated Pt species with tunable Si/Al ratios were synthesized to allow the formation of Pt nanoparticles (NPs) with almost the same loading amount, particle size

Furfural (FFR) is one of the most important biomass derivatives, usually obtained by initial hydrolysis of xylose oligomers derived from hemicellulose to xylose and then acid catalyzed dehydration. The FFR liquid-phase hydrogenation reaction conditions are mild, which is conducive to connecting with upstream chemicals. The solvent systems play a crucial role in the selectivity of target products and

Antibiotic resistance has emerged in recent years, posing a threat to human health and the environment. There is promising evidence that Fe3O4 nanomaterials can act as catalysts for the breakdown of antibiotics in aqueous systems. Herein, Fe3O4 was synthesized using a hydrothermal technique, and its potential as a catalyst for tetracycline (TC) degradation in the persulfate (PS) system was explored

Developing accurate kinetic models to predict cracking processes is essential for enhancing production quality and efficiency. Establishing a comprehensive free radical network that precisely predicts the product distribution in the cracking processes of all light hydrocarbons presents significant challenges. This study introduces a reaction network initiated from four individual hydrocarbons using

Distillation is arguably the most studied unit operation in the chemical engineering literature. Thousands of papers and dozens of books over the last century have been devoted to the design and control of distillation systems. The reason for the extensive interest is the high energy consumption of the thousands of distillation columns operating around the globe for separating a host of different mixtures

Pervaporation technology has shown great potential for organic solvent recovery and separations in biorefinery industry. However, industrial application of polymeric pervaporation membranes is still constrained by the slow mass transfer property and severe permeability-selectivity trade-off effect. Herein, we propose a novel electrospraying strategy to prepare high-performance covalent organic fra

Carbon dioxide (CO2) is the most significant greenhouse gas and one of the strategies to reduce CO2 emission is to convert CO2 into commercially valuable products. Currently, methods that can effectively capture and convert CO2 into carbonate nanomaterials, which have unique applications in various fields, have rarely been reported, and there are no universal methods that can capture and convert CO2

Wound repair is a common clinical challenge and is critical to patients’ life quality after skin injuries. Despite extensive efforts, the wound healing remains unsatisfied due to the complicated cell behavior and biochemistry of the wound healing process. In recent years, biomaterials have gained attention for their potential to promote skin regeneration, underscoring the need for innovative materials
