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

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

Electroluminescent devices, particularly in fiber form, demand highly transparent and conductive materials as external electrodes to maintain high brightness during stretching. As a result, materials with poor conductivity but good transparency, or good conductivity but poor transparency, are restricted in their applicability. Addressing this challenge, we introduce a compensation strategy for external

A key challenge in achieving a circular economy within the plastics industry lies in the upcycling and revalorization of post-consumer recycled (PCR) thermoplastic polyolefins (TPOs). PCR polyolefins typically exhibit inferior mechanical properties compared to virgin materials, limiting their use to low-value applications. Covalent adaptable networks (CANs), a class of dynamic crosslinked structures

Icephobic surfaces (e.g., superhydrophobic surfaces and slippery surfaces) have significant economic, energy and safety implications by offering prevention and easy removal of ice in many critical applications. So far, the durability of these surfaces remains to be a major concern, preventing their adoption in practice. Here, we design a low-surface-energy framework of bridging rigid nanoparticles

Achieving in vivo fast and long-lasting fluorescent tracking to short lived NO becomes challenging, which arises from probes needing efficient interaction, hindered by uncontrollable self-aggregation and a preference for hydrophobic conditions in NO-specific reactions. It is imperative to transform the uncontrollable aggregated structure to dispersed structure and umpolung of the nanoenvironment from

Two-dimensional MoS2 materials exhibit considerable promise for elemental mercury adsorption. However, challenges persist to identify the intrinsic active site in MoS2 adsorbent for Hg0 immobilization. In this work, three MoS2 samples with different sulfur vacancy concentrations and sulfur vacancy species, namely few-layer MoS2, multi-layer MoS2, and edge-rich MoS2, were engineered to confirm the pivotal

This study introduces a novel synthesis of sulfur (S)-doped Ag3PO4 photocatalyst using a simple precipitation method facilitated by ammonium sulfate ((NH4)2SO4). The calcination at 200 °C in air optimized the photocatalytic performance, leading to the complete degradation of cylindrospermopsin (CYN) within only 5 min under visible light irradiation. The degradation rate constant for the calcined S-doped

Rampant dendrite growth and hydrogen evolution reaction of Zn anode severely hinder the practical application of aqueous zinc-ion batteries (AZIBs). Traditional surface modifying layers tend to have distinct interface with the Zn plate, which readily results in detachment and failure of the modification under repeated cycling. Herein, inspired by mussel adhesive proteins, a uniform and dense polydopamine

The heterogeneous migration of dual ions within the gel polymer electrolytes (GPEs)-based lithium metal batteries leads to significant concentration polarization and compromises interfacial stability during cycling. Therefore, an in-situ GPE (BAEDA-PETEA-LE-PAN) is fabricated in polyacrylonitrile (PAN) porous membrane, with the benzene ring-containing bisphenol A ethoxylate diacrylate (BAEDA) oligomer

Aptamer-based biosensing methods, despite achieving advancements in the detection of tumor-associated proteins, are only effective for a limited number of specific proteins and thus have restricted clinical value. This is mainly attributed to the requirement of prior knowledge and precise modulation of the aptamer structure, or the special spatial distribution of multiple binding sites in the target

Studying surface-adsorbed species for catalytic oxidation reactions at the atomic scale has been challenging owing to the occurrence of reactions at elevated temperatures. Herein, we report an acid etching in conjunction with incipient wetness impregnation strategy to construct the asymmetric active sites (isolated Pt atoms and dispersed CuxO) supported on the diversely defective CeO2/halloysite nanotubes

Film capacitors based on polymer dielectrics are key components in pulsed power systems. But they always suffer from severe deterioration in energy storage performance at high temperatures because of accelerated carrier transfer and thermal runaway. Incorporating ceramic fillers into polymer is one of the most promising strategies to suppress the high-temperature carrier transfer. However, poor compatibility
