These wastes contain chitin, an abundant natural polymer found next to cellulose. Thus, disposal of this waste becomes a huge problem for the environment; besides this, reutilization boosts the circular economy. Chitin is partially deacetylated to yield the economically useful product of chitosan and is a heteropolymer. The current study isolated chitosan from mushrooms and various marine crustaceans, i.e., crabs, shrimp, and fish. Chitosan was extracted from marine crustaceans by demineralization, deproteination, and deacetylation. Later, extracted chitosan was characterized by physicochemical characteristics like deacetylation degree, ash content, protein, color, fat-binding capacity (FBC), water-binding capacity (WBC), pH, and moisture content. The result showed that chitosan yield ranges from 13.0% to 17.0%, the degree of deacetylation range from 82.0% to 85.0%, ash content range from 0.8% to 3.0%, and protein content is below 1.0%. The FBC and WBC range between 320% and 444% and 535% and 602%, respectively. The pH and moisture content range from 7.4 to 8.0 and from 2.0% to 4.0%, respectively. Overall, results specified that crustacean waste was an exceptional chitosan source with availability and production consistency.","PeriodicalId":12758,"journal":{"name":"Green Processing and Synthesis","volume":"137 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":"135318465","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 synthesized NPs were characterized with XRD, FE-SEM, FTIR, and PL spectroscopy measurements. SrSnO2 NPs were analysed for antimicrobial and anticancer activities. The XRD analysis revealed that the synthesized samples exhibited a tetragonal rutile crystal structure type of tin oxide. The EDX spectrum conforms to the chemical composition and elemental mapping of SrSnO2 NP synthesis. At 632 cm−1, the O–Sn–O band was observed and chemical bonding was confirmed using an FTIR spectrum. The PL spectrum identified surface defects and oxygen vacancies. The SrSnO2 NPs were tested against both Gram-positive and Gram-negative human pathogens. The synthesized nanoparticles exhibited effective antibacterial properties. The anticancer effects of SrSnO2 nanoparticles were also assessed against MCF-7 cells, and growth was decreased with increasing concentrations of the nanoparticles. Dual staining revealed high apoptosis in SrSnO2 NP-treated MCF-7 cells, proving its apoptotic potential. To conclude, we synthesized and characterized potential SrSnO2 nanoparticles using a green approach from the Mahonia bealei leaf extract. Further, green SrSnO2 nanoparticles showed significant antibacterial and anticancer properties against breast cancer cells (MCF-7) through apoptosis, which suggests a healthcare application for these nanoparticles.

Cashew nut shells (CNS) or Cassia fistula pods (CFP) were pyrolyzed at 400°C, 500°C, or 600°C, with biomass-to-activated carbon ratio set at 70:30, 80:20, or 90:10.

This work investigated, through geochemical modeling, the extraction of europium and ytterbium carbonates from rocks containing one of four silicates (chrysotile, forsterite, montmorillonite, and phlogopite) via chemical (mineral acid) or biological (organic acid) leaching. The results indicated conditions that led to either congruent or incongruent dissolution of the mineral phases and the formation of transient mineral phases. Chemical leaching models suggest that REE carbonates are recoverable in one-step leaching from forsterite and chrysotile rocks, while they are recoverable in a secondary leaching step from montmorillonite and phlogopite rocks. Gibbsite as a transient phase is shown to complicate REE recovery, potentially requiring reactive extraction. REEs have the potential to be recovered from silicate rocks via chemoorganotrophic bioleaching, but the process configuration would differ depending on the predominant minerals that make up the rock, and the type of REE present in it.","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":"46753808","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}

Ultraviolet spectrum at 416 nm confirmed the formation of AgNPs. X-ray diffractometer calculated size was reported to be 42.47 nm. The SEM analysis confirmed spherical-shaped AgNPs. FT-IR suggested that the phytochemical groups present in the KE extract and their nanoparticles (NPs) are responsible for the biosynthesized of NPs.

Statistical analysis showed that both KE and AgNPs exhibited non-competitive type inhibition against AChE, i.e. V max decreased (34.17–68.64% and 22.29–62.10%), while K m values remained constant.

The most commonly used nanoparticles are titanium dioxide nanoparticles (PF-127 coated TiO 2 NPs), which can be formulated with physical, chemical, and environmental factors. The establishment of an economical and environmentally beneficial method for its fabrication is due to increasing concerns about human health impacts. In this exploration, green Pluronic F-127 (PF-127) coated TiO 2 NPs using leaf extracts of Atractylodes macrocephala have been formulated and studied through various methods. PF-127 coated TiO 2 NPs were 60 nm large and a polygonal rutile-type crystalline structure was observed. Moreover, the NPs’ antimicrobial capacity against several pathogens was investigated. The cytotoxicity of the NPs against HEp-2, KB, and Vero cell lines was assessed using the MTT test. Increased antimicrobial potential of PF-127 coated TiO 2 NPs against several pathogens was noted. Furthermore, NPs displayed remarkable antioxidant activity, which increased with concentration. The NPs exhibited significant cytotoxic effects against HEp-2 and KB cell lines but failed to demonstrate toxicity against Vero cells. This is indicative of their cytotoxic potential against cancer cell lines and non-toxic nature towards healthy cells. This indicates that PF-127 coated TiO 2 NPs possess beneficial antimicrobial and antitumor properties.","PeriodicalId":12758,"journal":{"name":"Green Processing and Synthesis","volume":"30 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":"135007957","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}
