The preparation of di-isopropyl ether (DIPE), as an important chemical solvent, by isopropanol (IPA) etherification is limited by chemical equilibrium and azeotropic formation in its production processes. A novel sustainable etherification process based on reactive distillation (RD) coupled with extractive distillation is proposed. The reaction of IPA etherification was carried out by cation exchange

CO2 mineralization is a significant method for effective CO2 emission control because of formation of stable carbonate products and the availability of abundant mineral resources. The economic concern of the direct aqueous CO2 mineralization prevents the application to global warming mitigation. This work discovers that the CO2 mineralization of olivine can be significantly enhanced by using nitriloacetate

Massive spent lithium-ion batteries (LIBs) were emerged worldwide as a consequence of the extensive use in energy storage applications. The recovery of cathode electrode materials from spent LIBs has received great attention due to economic benefits, which has led to the neglect of the deep utilization of low-value copper current. The present study focuses on the selective crushing of copper foil and

In recent years, nitrobenzene (NB) leakage has emerged as one of the most pressing environmental issues related to groundwater contamination that requires immediate attention. This study aimed to combine S-nZVI reduction with persulfate (PDS) oxidation for NB degradation in aquatic solution. The strong synergistic effect of reduction and oxidative degradation processes in the S-nZVI/PDS system was

It is well known that the emission of volatile organic compounds (VOCs) is a significant threat to human health and the ecological environment, and toluene is a typical representative of aromatic VOCs, whose elimination makes an important contribution to the prevention and control of air pollution. Absorption is the classical process to eliminate air pollutants, but the application of absorption is

Graphene oxide membrane (GOM) shows great advantages in nanofiltration with the hydrophilicity and the tunable two-dimensional nanochannels. However, the instability in solution hinders the further utilization of GOM in nanofiltration. Therefore, we presented a method to improve the stability and permeability by constructing vertical channels using swift heavy ion (SHI) irradiation. In this work, the

This paper presents a novel multigeneration framework based on fossil fuels, which offers several advantages such as high thermodynamic efficiency, low electricity and liquid carbon dioxide (CO2) production costs, and significantly reduced pollutant emissions. The simulation was carried out using the Aspen HYSYS software. The thermodynamic analysis revealed that the process achieves a total exergy

Prostate cancer serum biomarkers, such as the U.S. Food and Drug Administration (FDA)-approved prostate specific antigen (PSA), are valuable markers of diagnosis, response to treatment and disease progression. Despite the expected benefits of using PSA to better manage the mortality and morbidity associated to prostate cancer, sample complexity and interference within analysis make its quantification

Oxygen-containing groups on the surfaces of materials (i.e., –COOH and –OH) are vital to the adsorption of toxic metals. Acrylic acid is used as a green grafter to enhance the density of these groups in carbonaceous materials, whereas ammonium cerium nitrate is used as an initiator. Hydrochar (prepared via hydrothermal carbonization at 190 °C), biochar (generated via pyrolysis at 800 °C), and activated

Control of deposit formation during skim milk microfiltration (MF) remains challenging, particularly in membranes with spacer nets between membrane layers like flat-sheet and spiral-wound membranes, due to the extensive occurrence of flow shadows behind spacer filaments. One approach to improve process control and efficiency is applying pulsed or alternating flow, which creates regular fluctuations

Desalination using solar-driven photothermal evaporators (SPEs) is of great significance for solving mankind's current shortage of fresh water. Herein, inspired by the vascular bundles for the directed and rapid transport of water and organic pollution such as inorganic salts in the vascular system of sugarcane, a polydopamine (PDA) @ attapulgite (ATP) based biomimetic aerogel (named as PAS aerogels)

Developing the efficiently degradation of organic pollutants in heterogeneous Electro-Fenton (E-F) process was still a challenge. In this work, the synthesized CeO2 and MoS2 were used to modify graphite felt (GF) for obtaining a novel electrode defined as CeO2@MoS2@GF, constructing a heterogeneous E-F system that could in-situ electrically generate and activate H2O2, thereby efficiently degrading sulfamethoxazole
