To remove dioxin residues from contaminated water, CuZn-ZIFs, a material from bimetallic zeolitic imidazolate frameworks (ZIFs) has been synthesized and explored its efficacy treatment with dibenzofuran (DBF). The pristine structure of CuZn-ZIFs was confirmed using powder X-ray diffraction, Fourier-transform infrared, thermogravimetric analysis, energy-dispersive X-ray, Brunauer–Emmett–Teller, and scanning electron microscopy. CuZn-ZIFs exhibited its role as a heterogeneous catalyst promoting H2O2 oxidation and as an adsorbent in DBF treatment. Herein, at room temperature, more than 86% of DBF adsorbed and 90% of DBF degraded in the presence of H2O2 with 10 mg catalyst dosage, 30 ppm of DBF within 40 and 60 min, respectively. Remarkably, the CuZn-ZIFs’ reusability of each process showed a high efficacy removal with over 80% after five cycles. Therefore, CuZn-ZIFs synthesized could be a prospective candidate for the indirect or direct degradation of dioxins/DBF derivatives from contaminated water.

The present study brings an amalgamation of nanoscience and “clean technology” by fabricating nature-friendly nanoparticles (NPs) sans the use of chemical surfactants using Indian mustard seed, Brassica juncea L. The as-synthesized NPs were characterized to assess their average size, crystallinity, morphology, and constituent functional groups through conventional techniques: dynamic light scattering (DLS), X-ray diffraction (XRD), scanning electron microscopy (SEM), and Fourier-transform infrared spectroscopy (FTIR). The NPs were crystalline in nature and exhibited a mean size of 205.5 nm (PDI of 0.437) being primarily polygonal in shape. Additionally, the therapeutic efficacy of the green NPs was evaluated based on their cytotoxic effect against two human cancer lines, MCF-7 and HepG-2. Both the NPs and the bulk seeds showed a dose-dependent cytotoxic effect. However, an assessment of the antiproliferative/cytotoxic potential of the green NPs versus the bulk seeds showed that the NPs were relatively more efficacious on both cell lines. Taken together, the mustard seed NPs could be potential nutraceuticals considering the green credential in their mode of biosynthesis.","PeriodicalId":12758,"journal":{"name":"Green Processing and Synthesis","volume":" ","pages":""},"PeriodicalIF":4.3,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49052028","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

If not collected and transported promptly or treated improperly, it is highly likely to pollute the environment and spread diseases. Because the lipid content in kitchen waste is high and a portion of organic matter is not subject to hydrolysis, the development of anaerobic digestion technology has been greatly limited. Kitchen waste was pretreated with NaOH, KOH, and Ca(OH) 2 with different concentrations, and 50 days sequencing batch mesophilic anaerobic digestion experiments were conducted. This study sheds light on the pollution reduction and energy generation of kitchen waste. The results are as follows: (1) The lipid content of kitchen waste could be reduced, and the concentration of dissolved organic matter could be increased by pretreating with alkali. The degradation rate of kitchen waste lipid reached a maximum of 50.51%, if 3% NaOH was added, and the soluble chemical oxygen demand concentration was increased by 235.3%. (2) The cumulative methane (CH 4 ) output and biogas production efficiency were improved in the anaerobic digestion process with kitchen waste pretreated with alkali. The maximum daily gas output of kitchen waste pretreated with NaOH and KOH took place on the 11th to 12th day, with the biogas production efficiency of 40.4 and 45.2 mL·g·VS −1 . The cumulative CH 4 output was increased from 370.2 mL·g·VS −1 (untreated) to 393.1 and 434.1 mL·g·VS −1 , respectively. In addition, the concentration of CH 4 in biogas was increased from 54.8% (untreated) to 59.1% and 61.7%, respectively. (3) The Chao1 and Ace values of bacteria were increased first and then decreased. On the 10th day, the diversity of bacteria reached the highest value, and on the 20th day, the diversity of archaea reached its maximum. Therefore, it was verified that the improvement in the hydrolysis acidification efficiency and degree was crucial for the rapid and complete anaerobic digestion reactions.","PeriodicalId":12758,"journal":{"name":"Green Processing and Synthesis","volume":"122 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135211883","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The works involved the examination of physico-chemical characteristics of carbonate lake sediments and the analysis of impact of the sediments’ depth extraction on their chemical composition and physico-chemical properties. The lake sediment consists mainly of calcium carbonate (CaCO3) and can be a potential filler for plastics. Tests were carried out to determine chemical composition of the sediments and their thermal stability. The thermogravimetric analysis showed the three stages of the thermal decomposition. Sediments in deeper layers of the lake are characterised by the presence of not only CaCO3 and silica, but also other chemical compounds, including aluminosilicates. In addition, as the depth increases, the average size of sediment particles changes, with the main fraction particle size being the smallest for the material from the 6–12 m depth.

Disappointingly, various adverse effects are being observed with currently used antiepileptic drugs. Nanomedicine represents an effective strategy to overcome these limitations with a better central drug delivery. Hence, our work aimed to unravel the antiepileptic efficacy of rutin (Rut) loaded with selenium nanoparticles (SeNPs) against pentylenetetrazole (PTZ)-challenged mice. Ten days before PTZ (60 mg·kg−1) intraperitoneal injection, mice were orally administered Rut (100 mg·kg−1), sodium selenite (0.5 mg·kg−1), SeNPs (100 mg·kg−1), or sodium valproate (reference drug, 200 mg·kg−1). Remarkably, administration of Rut-loaded SeNPs (Rut-SeNPs) to epileptic mice markedly increased the latency time and decreased the severity and duration of seizures. Remarkable increases were also noticed in acetylcholinesterase, brain-derived neurotrophic factor, dopamine, and norepinephrine levels in epileptic mice treated with Rut-SeNPs. Furthermore, Rut-SeNPs boosted the cellular antioxidant defense by increasing superoxide dismutase, catalase, GSH, Nrf2, and HO-1, along with decreased malondialdehyde and nitric oxide levels. In addition, the nanotherapy successfully mitigated the inflammatory mediators (tumor necrosis factor-α, interleukin-6, cyclooxygenase-2, and nuclear factor kappa B) in mice hippocampus. Rut-SeNPs antagonized neuronal apoptosis by decreasing Bax and caspase-3 and increasing the levels of Bcl-2. Conclusively, the present work suggests Rut-loaded SeNPs as an effective antiepileptic therapy through correction of disturbed neurotransmitters, oxidative status, neuroinflammation, and apoptosis.","PeriodicalId":12758,"journal":{"name":"Green Processing and Synthesis","volume":" ","pages":""},"PeriodicalIF":4.3,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47526600","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
