Biogas is a promising energy source that could replace non-renewable, polluting energy. However, some impurities, including carbon dioxide, hydrogen s…

As the shipping industry accelerates its decarbonization efforts, onboard carbon capture and storage (OCCS) has emerged as a critical transitional strategy. Existing studies on OCCS have mainly focused on fragmented aspects of the technology, resulting in a lack of systematic evaluations. This review introduces a novel framework that systematically assesses OCCS technologies through the lens of sorption

The recently developed poly(epoxyether) (PEE) membranes show great potential to treat a variety of liquid and gas streams thanks to their impressive chemical, thermal and mechanical robustness, even allowing application in extreme pH and strongly oxidative conditions. A significantly shortened synthesis protocol is however still needed to enable the industrial-scale production of PEE-based thin-film

In this work, a novel, large scalable, multifunctional carbon fabrics/rayon/polyur-ethane (CF/rayon/PU) Janus membrane was designed and successfully developed. The Janus membrane was purposely designed based on premises of: i) mass production, excellent photothermal conversion, and hydrophobicity of CF that is selected to be upper layer. ii) effective water transporting property of rayon that is chosen

Singlet oxygen (1O2) is considered to be a superior electrophilic active species for degrading electron-rich antibiotic contaminants. However, selective generation of 1O2 remains a huge challenge. Herein, oxygen-vacancy assisted Bi2Fe4O9/BiOCl homology heterojunction was fabricated through hydrochloric acid etching coupled with in-situ solvothermal method for photocatalytic peroxymonosulfate (PMS)

Bubbling is usually accompanied by an apparent sound. Determining the acoustic characteristics and sound generation mechanisms of this process is essential for the application research on the passive acoustic monitoring. In the present work, sound generation mechanisms of bubbles during necking fracture at an orifice and bursting at a gas–liquid interface were investigated using the simultaneous sound-image

Functional mechanism of a new high-efficiency collector was studied in ilmenite flotation. Microflotation experiment showed that flotation recovery of ilmenite remained above 80 % using 50 mg/L dodecyl dimethyl benzyl ammonium chloride (DDBAC) collectors at a pH range of 1.0 ∼ 10.0, while the recovery of titanaugite decreased from 67.06 % at pH 6.0 to 19.92 % at pH 1.5. Contact angle and AFM analyses

A significant challenge remains in developing a reusable, cost-effective, and eco-friendly adsorbent for the efficient removal of malachite green (MG) dye. Inspired by the dynamic grasp-and-release mechanism of octopus tentacles, this study developed a series of hydrogels using carboxymethyl fenugreek gum as the foundational polysaccharide. Acrylic acid (AA) was grafted as the primary comonomer, while

Gold hydrogen, formed by natural processes and found within the Earth’s crust, is frequently mixed with helium gases. Due to the significant economic value of both hydrogen and helium, the development of efficient recovery and separation technologies is critical. Currently, cryogenic distillation is the only commercially viable method for helium production, but it is highly energy intensive. While

This study focuses on the development and characterization of dense and thin film composite (TFC) membranes based on polymer of intrinsic microporosity (PIM-1). Various membrane formulations were fabricated, including PIM-1/Matrimid®5218 blends at ratios of 90/10 and 10/90 wt%, and PIM-1/6FDA-DAM:DABA (3:1) blends at ratios of 90/10, 50/50, 10/90, 5/95, and 2.5/97.5 vol./vol. Additionally, TFC membranes

Dihydroxylammonium 5, 5′-bistetrazole-1, 1′-diolate (TKX-50) is a new high-energy and insensitive material with broad application prospects. However, the discharge of TKX-50 wastewater from its production and applications not only causes the waste of high-value explosives, but also pollutes the environment. The traditional used adsorbents are poor adsorption efficiencies and recyclability performance

Crystallization systems exhibiting ultra-wide metastable zone widths (MSZWs) due to pronounced solute–solvent hydrogen bonding interactions are characterized by impeded de-solvation and aggregation of solute molecules, resulting in nucleation inhibition. In our previous experiment, we found that the MSZW of 4,4′-Oxydianiline (ODA) in N, N-Dimethylacetamide (DMAC) can be as high as 40–50 K. Here, we

In this work, a diamine (2-(bis(3-amino-4-hydroxy-5-methylphenyl)methyl)benzoic acid, OBP) was synthesized using o-cresolphthalein and copolymerized with 4,4′-(hexafluoroisopropyl) phthalic anhydride (6FDA) and paraphenylenediamine (PPDA) to yield a 6FDA‐OBP/PPDA (1:3) (6FOP) copolyimide. The copolyimide was crosslinked by Ca2+ or Fe3+. The influence of the coordination effect of ion crosslinking on

Polydimethylsiloxane (PDMS)/ceramic tubular pervaporation membranes hold significant promise for advancing industrial separation processes, owing to their robust mechanical stability, chemical resistance, and exceptional separation performance in challenging operating conditions. However, achieving uniform PDMS layers on ceramic supports with complex surface properties and intricate pore structures
