The incorporation of zeolite and amine-zeolite ZSM-22 in the selective PA layer resulted in distinct ridge-like and valley-like surface morphologies, contributing to improved hydrophilicity and fouling resistance. Comprehensive characterisation using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and water contact angle (WCA) analysis confirmed the successful incorporation and uniform dispersion of zeolite and amine-zeolites fillers within the PA layer. The functionalised PA layers demonstrated superior hydrophilicity, resulting in significant improvements in water flux, high anti-fouling ratios and salt rejection compared to the zeolite PA-TFC membranes. The obtained PA-TFC membrane structural design, supported on ZSM-22/polyethersulfone ultrafiltration (ZSM-22/PES UF) substrate, played a crucial role in ensuring mechanical stability and promoting interfacial bonding. The amine-zeolites PA-TFC membranes achieved exceptional water fluxes, reaching up to 48.92 L·m⁻²·h⁻¹ ·bar⁻¹ , and exhibited fouling ratios ranging from 65.78 % to 73.68 % as well as salt rejection to about 77 %. Notably, the H<sub>2</sub>N@T60-ZSM-22/PA@ZSM-22/PES configuration showed the lowest fouling ratio of 65.78 % and higher salt rejection, demonstrating the potential for selective filtration under low-pressure conditions. Despite minimal performance variations among the different membrane configurations, consistent and robust antifouling behavior was observed across all samples. These findings underscore the promise of amine-zeolite ZSM-22 PA-TFC membranes as high-performance candidates for achieving enhanced flux, fouling resistance, and selective separation, contributing valuable insights for the advancement of membrane technology in water treatment applications.</div></div>","PeriodicalId":100960,"journal":{"name":"Next Sustainability","volume":"6 ","pages":"Article 100097"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143163057","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Incorporating MK as a partial or additive for cement in concrete can negatively affects its workability, especially at higher replacement levels, and may also adversely affect concrete strength. Magnetized water (MW) is a technique of treating regular tap (TW) water by exposing it to a magnetic field with a specific intensity and a certain number of cycles, making the water magnetized. The incorporation of MK and MW in concrete promotes sustainability by reducing cement consumption, thereby lowering carbon emissions. This research investigates the effects of using magnetized water (MW), prepared in a magnetic field of 1.4 tesla, on the workability and compressive strength of concrete containing MK in different ratios. MK was incorporated at 5 %, 10 %, and 20 % as either a partial replacement or additive to cement by weight. Two sets of concrete mixes were prepared: one with MK (ranging from 0 % to 20 % as a replacement and additive) mixed with ordinary tap water (TW), and the other with the same MK percentages mixed with MW. The results of the hardened concrete tests indicated that the optimal MK ratio for concrete was 10 + % (10 % as an addition to cement), whether or not MW was used. The slump of concrete decreased when TW was used; however, using MW improved the slump by up to 2 %. The compressive strength increased by 13 %, 11 %, and − 5 % at 7, 28, and 365 days, respectively, with no MK and the use of MW. When 10 + % MK was used with MW, the compressive strength improved by 5 %, 0 %, and − 5 % at 7, 28, and 365 days, respectively. Also, in the SEM images, the cement pastes in the presence of MK and MW became denser and more cohesive compared to the control mix without them, indicating an improvement in the hydration process with the efficient use of MW. Also, FTIR analysis was conducted to the optimal mixes to show the function groups of these mixes in microscale.

The primary objectives of this work are to: i) introduce the morphological and physicochemical properties of prevalent geocolloid varieties and explain their formation mechanisms, ii) outline the mechanistic pathways by which geocolloids alter contaminant transport dynamics, and iii) analyze the ramifications for applications such as coal mining, hydraulic fracturing, chemically-enhanced oil recovery, and radionuclide storage. A systematic literature review was conducted, synthesizing findings from experimental investigations, computational simulations, and field observations. These studies reveal that geocolloids can facilitate or impede contaminant mobility by modifying parameters such as effective diffusivity, rheological properties, and interfacial deposition kinetics across multiple spatiotemporal scales. The presence of geocolloids introduces non-linear complexities in contaminant fate and transport that go beyond conventional advection-dispersion models.

The G Raman band of the biochar appeared to be less intense in the nanocomposite, compared to pristine biochar prepared as a reference, meaning Ni nanoparticles hinder carbonaceous graphitization during pyrolysis.
