The nanoparticles were characterized using X-ray diffraction and FT-IR. On the targeted weeds, the nanoherbicides were sprayed at the third to fourth leaf stage. Six different doses were applied. The mortality and visual injury caused by both chitosan-based nanoherbicides reached 100% at the recommended dose of standard herbicide. The 5-fold lower dose exhibited weed density and maximum wheat yield and related parameters. For the same traits, the nanoherbicide at 10-fold lower dose of commercial herbicides showed a comparable influence as the suggested dose. The size of both herbicides was found to be 35–65 nm. It was observed that the clodinofop-propargyl nanoherbicide has an intense peak appearing at a 2 θ value of 29.83°, corresponding to the (176) plane of the anatase phase and NPs of fenoxaprop- P -ethyl showed an intense peak around the 2 θ value of 30.55° corresponding to the (74) plane of the anatase phase. The FT-IR spectra of fenoxaprop- P -ethyl clearly showed that the major functional groups were located in the FT-IR region between 610 and 1,840 cm −1 and the major functional ones of clodinofop propargyl were located in the FT-IR region between 640 and 1,740 cm −1 . Nanoherbicides could restore the efficacy of conventional herbicides by improving stability and reducing toxicity.","PeriodicalId":12758,"journal":{"name":"Green Processing and Synthesis","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134890456","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}

According to the results, when the working pressure of the absorber column increases, the process becomes significantly exergy deficient, with an exergy loss of 7.63 MW compared to 5.7 MW for a normal MEA process. The majority of the exergy deficit is due to flue gas compression effort, which accounts for 99% of the total process exergy. The process’s exergy shortfall can be improved by lowering the absorber pressure from 10 to 3 atm, lowering the carbon dioxide removal efficiency from 90% to 60%, and increasing the solvent-to-gas ratio from 075 to 7.05. Furthermore, the incorporation of an energy recovery device could allow for an 80–90% reduction in the energy consumed by the gas compressor when running at 10 atm, from 5.7 to 1.2 MJ‧kg CO2 −1. With this adjustment, the deep eutectic solvent-based process can match or outperform the corresponding aqueous alkanolamine solvent-based process in terms of exergy destruction and specific energy consumption.","PeriodicalId":12758,"journal":{"name":"Green Processing and Synthesis","volume":null,"pages":null},"PeriodicalIF":4.3,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46325027","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}

To evaluate the effectiveness of the green produced AgNP therapy, the mosquitocidal activity of A. stephensi, cytotoxicity assay in Vero cells, and antiplasmodial activity assay were performed. The larval and pupal toxicity of biosynthesized AgNPs against the malarial vector A. stephensi is 90% promising in laboratory settings at low dosages (10 ppm). When tested on African green monkey kidney cells, the cytotoxic effect of biosynthesized materials was found to be inappropriately damaging up to 100 g·mL−1. The antimalarial efficacy of AgNPs was evaluated against P. falciparum strains. The parasites that were restrained by AgNPs at 100 ppm had the highest parasitemia restraint rate (80.4%). AgNPs then showed significant in vitro antimalarial activity against P. falciparum.

Our extended study on micro-impacts showed the formation of carboxylic acids, amines, and amino acids from Fe3C/Fe4N, carbon, and carbonates/nitrates by milling up to 30 h at 40 G. Fe(CO2)2·2H2O accelerated the formation a step further. Cu addition caused superior capability to form amines and amino acids. Two reaction fields were disclosed. In the impact field, the hydration of ferrous materials generated hydrogen which hydrogenated inorganic carbons to organics and ferrous transient materials and, in the maturing field, hydrogenated materials were then transformed into complex organics. Iron and CO2 were presumably the key components in the Hadean Ocean. Discussions on the mechano-chemical reaction were extended to serpentinization coupled with diastrophism of oceanic crusts and further led to a depiction that organic precursors were formed by micro-impacts and frictions of rocks and sands (like milling-balls) due to tremors in crusts. It provides a new path on how organic precursors were formed on the aqua-planet Earth.","PeriodicalId":12758,"journal":{"name":"Green Processing and Synthesis","volume":null,"pages":null},"PeriodicalIF":4.3,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42051891","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}
