Packed bed microreactors offer a promising platform for intensifying heterogeneously catalyzed reactions. To understand hydrodynamics therein, N2 or water flow was investigated experimentally through microreactors packed with glass beads in this work, corresponding to a microreactor to particle diameter ratio (D/d) of 1.29–25.12. The porosity of a single pellet string microreactor (D/d < 1.866) agrees

The traditional Pb-Ag anodes used in zinc electrowinning exhibit high overpotential for oxygen evolution reaction (OER) and poor mechanical strength, leading to high energy consumption. To overcome the shortcomings, Ti/SnO2-Sb2O4/PbO2-La-doped MnCo2O4.5 composite anode was prepared by this work. It demonstrated enhanced electrochemical performance, requiring 565 mV to reach the benchmark current density

The development of pilot plants is important in establishing new technology to close the gap between lab-scale and full-scale operations by minimizing technical uncertainties. Currently, limited research is available to evaluate different aspects of pilot plants for producing lignin-based materials before commercialization. This paper focuses on designing a safe and eco-friendly pilot plant for optimizing

Emission control of gaseous elemental iodine discharged from nuclear industries is of extreme importance for ecological environment and human health. An obvious barrier hindering the extensive application of activated carbon-based sorbents primarily derives from the absence of active ligands with satisfactory binding towards iodine. To effectively face this challenge, copper sulfide (CuS) with high

To recycle isobutanol and ethanol from wastewater, different extractive distillation flowsheets with different entrainers are proposed. Firstly, the entrainers glycerol (GI), ethylene glycol (EG) and different deep eutectic solvents (DESs) are compared from the perspective of relative volatility and quantum chemical calculation. Subsequently, the indirect extractive distillation (IED) process and direct

Electrocatalytic conversion driven by renewable energy generation is expected to emerge as an effective approach in reducing global reliance on fossil fuels and achieving environmentally friendly and sustainable development. However, regulating the electrocatalytic properties has emerged as a significant challenge in bridging the gap between theory and practical application. Fortunately, pulsed electrocatalysis

Ionic thermoelectric (i-TE) hydrogels have a high thermal energy utilization rate for low-grade heat, presenting a renewable energy supply option for sustainable global development. Conventional i-TE materials need to be conductive, stable and environmentally friendly, which remains a challenge today. This study presents a highly temperature-sensitive i-TE hydrogel with negative Seebeck coefficient

Room temperature phosphorescence (RTP) materials have important applications in biosensing, bioimaging, drug delivery, and photodynamic therapy for tumor diagnosis and therapy owing to their long luminescence lifetimes, large Stokes shifts, and no need for real-time excitation. Carbon dots (CDs) are a new type of RTP materials, which have attracted wide attention because of their long RTP lifetime

Epigenetic drugs have been used in the treatment of many diseases. Unfortunately, however, epigenetic drugs are not targeted, which makes the action of epigenetic drugs often systemic. This systemic epigenetic alteration can lead to a host of unwanted side effects. To improve delivery targeting and enhance the efficacy of drugs, the application of novel drug carriers in the field of epigenetic drug

Preparation of fire safety and high mechanical strength epoxy resin (EP) has become a hot topic for its valuable applications in construction and other fields. Here, bis-2-aminobenzimidazole-modified phenyl phosphonates (PP-BMI) with symmetric structures were synthesized by a simple chemical modification strategy, and its fine structure and composition have been thoroughly characterized. Due to the

Catalytic ceramic membranes with ozonation have gained increasing attention due to their high efficiency in removing organic pollutants for water treatment. The combination of ceramic membranes and catalytic ozonation can effectively create a synergistic effect between the physical separation of ceramic membranes and the chemical reaction of catalytic ozonation, which is mainly attributed to the unique

Modulating surface terminating groups has been recognized as an effective approach for regulating the electrical properties of MXene. Nevertheless, achieving the simultaneous majorization of electrical and magnetic properties of MXene through terminating groups modulation remains an essential challenge. Herein, we present an innovative series of M−Ti3C2Tx (M = Fe, Co, Ni) with M−O bonds as partial

Environmental1 concerns have spurred research into replacing thermal power with microwaves in chemical plants to promote sustainability. However, there is a lack of established methodologies for scaling up microwave heating furnaces through analytical and experimental approaches. In this study, a sintered material intended for use as roadbed material was developed using concrete sludge cake and fly

Interface engineering is an effective approach towards developing low-cost highly efficient electrocatalysts for green hydrogen production in alkaline water or seawater environments. Herein, we have successfully fabricated an interface engineered Mott-Schottky heterostructure catalyst i.e., Fe3O4@Ni3S2, in which, Ni3S2 nanosheets are evenly dispersed on the surface of Fe3O4 flower-like nanosheets,

Benchtop pulsed field gradient (PFG) nuclear magnetic resonance (NMR) measurements of the intra-diffusion coefficient (Di∗ ) for binary gaseous mixtures are presented as a function of composition, for temperature and pressure conditions broadly relevant to industrial and geological processes. This required the design, construction, and application of a novel NMR-compatible sapphire sample cell. Measurements

The expansion of bubbles in viscous fluids in microchannels is normally overlooked. The bubble dynamics in liquids with varying viscosities (1.15 ∼ 101.47 mPa·s) and contact angles (29.3 ∼ 137.6°) in a microchannel were investigated under various inlet pressure drops (8 ∼ 202 kPa). The findings indicate that bubble formation occurs within a squeezing-shearing regime over a wide Capillary number range

This research investigates how combining forced periodic operation with spatially distributed catalyst activity can enhance heterogeneous catalytic processes. It focuses on analyzing reaction-diffusion phenomena within porous catalyst pellets. These pellets exhibit a Gaussian distribution of active sites, and the study investigates how externally forced periodic variations in bulk reactant concentration
