Various analytical techniques including XRD, HRTEM, FESEM, FTIR, UV-Vis, and DLS have been employed to characterizations. In terms of antioxidant activity, MoS₂ exhibited significant scavenging effects against various radicals including DPPH, hydroxyl, nitric oxide, hypochlorous, superoxide anion, peroxynitrite, and inhibited lipid peroxidation. It has been revealed that MoS₂ and ascorbic acid (standard antioxidant) are almost equally capable to inhibit lipid peroxidation and scavenge DPPH and hydroxyl free radicals, superoxide anion, hypochlorous acid, nitric oxide and peroxynitrite. In HCT 116 cells, MoS₂ has been demonstrated to decrease cell viability at an IC₅₀ concentration of 18.49 μg/ml. MoS₂ increases the ROS production and altered the levels of GSH and GSSG in HCT 116 cells. The decrease in cell viability for normal FHC cells was notably less severe compared to cancerous HCT 116 cells, indicating selective cytotoxicity. Paramount antibacterial activity of MoS₂ NSs towards both Gram positive and Gram-negative bacteria has been established. Overall, the findings suggest that MoS₂ possesses notable anticancer capabilities along with strong antioxidant and antibacterial properties. The MoS₂ NSs exhibit good photocatalysts for tetracycline (TC) degradation. The maximum 71 % degradation has been achieved within 50 min under visible irradiation. The synthesized catalyst exhibited stable performance over three reuse cycles, with post-reaction XRD analysis confirming the structural integrity of MoS₂.</div></div>","PeriodicalId":100960,"journal":{"name":"Next Sustainability","volume":"6 ","pages":"Article 100175"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144987954","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of this treatment was to make the lignocellulosic sheets suitable as water filtration membranes. To promote a cleaner production of the lignocellulosic sheets with no chemicals, both processes were conducted biologically using a common fungus, Aspergillus niger. This is another singularity of the study, as these processes are not known to have been run sequentially and from the same microorganism. The techno-economic analysis done showed that the proposed one-pot system is sustainable. Moreover, the results in this study confirmed that the biological process occurred, through the detection of the enzyme produced. A chemical composition analysis validated that amorphous constituents (lignin, pectin and hemicellulose) were removed to a high extent (40 – 50 %), thereby causing an enhanced cellulose content of 66 – 77 % (an increase of 30 %). Furthermore, the developed one-pot process allowed a reproducible decrease in pore size (58 %), giving the microfibre sheet a higher salt rejection capacity. Additionally, the banana microfibre sheets exhibited a high porosity of 98 % and a high water flux (460 – 1350 L/h m² bar), comparable to commercial membranes (around 1000 L/h m² bar). Furthermore, despite the expectation that the one-pot process would only maintain the mechanical strength, it caused an increase of 95 % in the wet tensile strength of the banana microfibre sheets while causing a maximum boost of 21 % in the dry tensile strength. Thus, the identified optimum conditions were acidic bleaching (pH: 3 – 5) and acid treatment of 8 days. In summary, following the one-pot process, the banana microfibre sheets were observed to be suitable for use as water filtration membranes due to their enhanced characteristics of the microfibre sheets. The one-pot system has resulted in an effective, cost-effective and eco-friendly process for successfully bleaching and acid-treating microfibre sheets.</div></div>","PeriodicalId":100960,"journal":{"name":"Next Sustainability","volume":"6 ","pages":"Article 100178"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145010171","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Bio-derived fuels have been blended with conventional fuels to address the depletion of fossil fuels and their associated greenhouse effect. The researchers focus on finding new technology that leads to carbon-free mobility. Renewable energy sources such as ammonia, hydrogen, and CNG are becoming increasingly popular as efficient substitutes for traditional fuels. Due to the concern about the production and storage of hydrogen, ammonia is gaining momentum due to its better hydrogen-storing capacity. This review paper aims to discuss the various ammonia production processes, the possibilities of ammonia as fuel in conventional CI engines, and the use of ammonia in internal combustion engines. Research has shown that the addition of ammonia to CI enhances its performance, and the use of dual fuel can boost the output's economic efficiency. However, it is important to note that this approach may also lead to increased NOₓ emissions. Some of the most important things that the review showed were that ammonia works well in dual fuel mode, 40–60 % diesel fuel energy is needed for maximum fuel efficiency, and NO emissions go down if ammonia replaces less than 40 % of the energy. For this reason, ammonia could potentially serve as a fuel for CI engines, leading to improved performance and a reduction in NOₓ emissions.</div></div>","PeriodicalId":100960,"journal":{"name":"Next Sustainability","volume":"5 ","pages":"Article 100116"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143455050","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}

High-speed shadowgraphy and embedded thermocouples enabled precise measurements of droplet diameter and surface temperature. Additionally, a validated multi-pseudo-component, transient two-phase evaporation model (developed using Aspen HYSYS) was used to simulate the evaporation process under high-temperature conditions. Experimental results showed that soybean oil (BF) had the highest evaporation rate, while rapeseed oil (RF) evaporated the slowest. Diesel exhibited puffing behavior at elevated temperatures, whereas biofuels demonstrated more uniform and stable evaporation dynamics.

This study introduces a novel systems-driven framework that integrates three key components: (1) the Environmental Drought Index (EDI), facilitating the inclusion of environmental flow deficits within compound drought assessments to complement traditional drought indices; (2) the Entropy-based Compound Drought Index (ECoDI), which combines conventional drought indices [Standardized Precipitation Evapotranspiration Index (SPEI), Standardized Soil Moisture Index (SSMI), Standardized Streamflow Index (SSI)] with EDI using Shannon entropy weights to emphasize signals with high informational variability; and (3) the joint application of Causal Loop Diagrams (CLDs) and the Cross-Index Synergy Matrix (CISM) to bridge drought science and governance. CLDs illustrate nonlinear feedbacks, while the CISM (a newly developed dual-matrix approach) translates ECoDI/EDI severity tiers into adaptive policy recommendations. Applied to the Jaraikela catchment in India’s Brahmani River basin, the framework highlights temporal mismatches in drought propagation (1982–2023), such as the rapid transition from meteorological to agricultural drought (lag of 1–2 months), the delayed onset of hydrological drought (lag of 2–4 months), and the persistence of environmental droughts (lag of 1–3 months after hydrological drought). The analysis identifies major drivers, including the impact of agricultural withdrawals on environmental flows and the effect of delayed monsoon onset on soil moisture deficits. Validation against the Vegetation Health Index (R=0.873, AUC-ROC=0.84) demonstrates ECoDI’s effectiveness in detecting compound drought events and capturing post-2000 intensification trends.
