Therefore, the goal of this work was to investigate the chitosan nanoparticles loaded with mesosulfuron methyl and mesosulfuron methyl + florasulam + (2-methyl-4-chlorophenoxyacetic acid) MCPA isooctyl herbicides as a possible environmentally benign substitute to manage weeds in wheat. Due to intriguing characteristics including biocompatibility, low allergenicity, biodegradability, and nontoxicity, chitosan biopolymers as sustainable chitin derivatives have received intense scrutiny in the biomedical business. The manufactured nanoparticles were characterized by using ultraviolet absorbance, scanning electron microscopy (SEM), X-ray diffraction (XRD), and Fourier transform infrared spectroscopy (FT-IR). The average particle size as revealed by SEM was 40–70 nm in a cluster form with the porous structure. The maximum absorption peaks of both nanoparticles of mesosulfuron methyl and mesosulfuron methyl + florasulam + MCPA isooctyl were 330 and 360 nm. The FT-IR analysis showed an intensive peak at 2θ value of 30.55° for mesosulfuron methyl and 32.79° for mesosulfuron methyl + florasula + MCPA isooctyl, which correspond to the 78 and 198 planes of the anatase phase, respectively. The nanoparticles were sprayed at the third to fourth leaf stages of the targeted weeds. Seven different doses were applied. A total of 100% mortality and visual injury were caused by the chitosan-based nanoparticles of both herbicides at the recommended dose of standard herbicide. The 5-fold lower dose showed the minimum chlorophyll content (5.75%), plant height (2.35 cm), fresh biomass (1.08 g), and dry biomass (0.33 g) of a weed mixture. For the same traits, the herbicide nanoparticles at 10-fold lower dose of commercial herbicides exhibited a similar effect as the recommended dose. Nanoherbicides could recuperate the conventional herbicide effectiveness by enhancing the stability and reducing the toxicity.","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":"46052858","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}

In this study, tanshinone IIA was encapsulated in poly(lactic-co-glycolic acid)-block-poly (ethylene glycol)-carboxylic acid (PLGA-PEG-COOH) nanoparticles, and its therapeutic efficacy on CIRI was investigated. Morphology and dynamic light scattering analyses were performed to identify and optimize nano-formulations. A drug release test was conducted using the dialysis method. The cytotoxic effect of tanshinone IIA on human neuroblastoma cells (SH-SY5Y) and brain endothelial capillary cells (hCMEC/D3) was measured using the MTT assay. The protective effect of PLGA-PEG-COOH-encapsulated tanshinone IIA against CIRI was evaluated in oxygen and glucose deprivation/reoxygenation-induced SH-SY5Y/IR cells and middle cerebral artery occlusion (MCAO) rats. Results showed that PLGA-PEG-COOH-encapsulated tanshinone IIA promoted viability and inhibited apoptosis of SH-SY5Y/IR cells (P < 0.01). Moreover, PLGA-PEG-COOH-encapsulated tanshinone IIA facilitated the invasion of SH-SY5Y/IR cells and repressed inflammation in MCAO rats (P < 0.01). Noteworthy, PLGA-PEG-COOH-encapsulated tanshinone IIA combined with angiopep-2 peptide presented a better inhibitory effect on CIRI than tanshinone IIA alone (P < 0.01). Angiopep-2 peptide contributes to traversing blood–brain barrier by recognizing lipoprotein-related protein expressed in the brain capillary endothelial cells. In conclusion, PLGA-PEG-COOH-encapsulated tanshinone IIA plus angiopep-2 peptide holds promising therapeutic potential toward CIRI.","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":"47863737","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}

It is an environment-friendly catalyst. Using Lewis acid immobilized as the catalyst, 2-methyl-6-propionyl naphthalene is synthesized by Friedel–Crafts reaction with 2-methylnaphthalene and propionic anhydride, which has a good development prospect. A variety of AlCl3 catalysts supported by H-zeolite molecular sieves are prepared using the solvent reflux method in the paper. It is found that AlCl3/Hβ has better catalytic performance. The results showed that AlCl3/Hβ catalyst is mainly composed of L acid. The acid content of B acid and the specific surface area increase, and the pore volume and pore size decreases. With the increase in AlCl3 concentration, the acid content of strong acid, medium strong acid, and weak acid increases, but the solubility of AlCl3 in CHCl3 is limited. When the concentration of AlCl3 is too high, too much AlCl3 is deposited on the surface of the molecular sieve, which is useless to its binding with Si–OH. AlCl3/Hβ’s activity is higher when the concentration of AlCl3 is 3 g·L−1, and the solvent is refluxed for 8 h and calcined at 550°C for 3 h. Under these conditions, the conversion of 2-methylnaphthalene is 85.86%, and the yield of β,β-methyl propyl naphthalene is increased to 81.19%.","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":"43367958","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}

One option to address Se deficiency is to biofortify plants with Se. Biofortification of forage with Se nanoparticles (NPs) is gaining more attention as an efficient and safe source of Se for livestock. The purpose of this study was to investigate the effect of different concentrations of NPs-Se (0, 30, 50, 100, 150, and 250 mg·L−1) on the growth of alfalfa harvested multiple times, and to provide a basis for the production of Se-enriched forages. Applying 50 mg·L−1 concentration of NPs-Se had the best effect on yield over three harvests. Over three harvests, low-dose NPs-Se (30 and 50 mg·L−1) application significantly increased peroxidase and superoxide dismutase activities, chlorophyll content and carotenoid content, and significantly decreased malondialdehyde content. The total Se content and Se accumulation in plants at the same harvest showed an upward trend with increasing Se concentration. At the same concentration, from first harvest to third harvest, Se content and Se accumulation showed an initially increasing and then decreasing trend. The evaluation found that foliar application of NPs-Se at 50 mg·L−1 could have the greatest positive effect on the growth and yield of multiple-harvested alfalfa.","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":"42607243","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 morphological and physicochemical features of Se–Fe NCs were evaluated by UV–visible spectroscopy, scanning electron microscopy, energy-dispersive X-ray, Fourier transform infrared, X-ray diffraction, and Zeta potential analysis. The findings showed that garlic cloves extract was a promising capping and reducing agent for the formulation of the NC. To explore the antioxidant potential of a bioinspired Se–Fe NC, 2,2-diphenyl-1-picrylhydrazyl and reducing power assays were performed. Furthermore, antioxidant efficacy was confirmed through antimicrobial activities against clinical pathogens. Phytosynthesized Se–Fe NCs (25, 50, 75, and 100 ppm) showed a dose-dependent response. Higher concentrations of Se–Fe NCs impose a more potent antioxidant and antimicrobial potential. The astonishing findings suggest that phytochemicals in Allium sativum extract are useful reducing agents in the formulation of well-defined Se–Fe NCs, and such NCs could act as competitive inhibitors against pathogens.

The effects of catalyst concentration, catalyst ratio, reaction temperature, reaction time, reaction pressure, and solvent ratio on the reaction of FDCA were investigated. The products are subjected to qualitative and quantitative analyses using high-performance liquid chromatography, infrared spectroscopy, and hydrogen nuclear magnetic spectroscopy. Moreover, considering the loss of catalytic liquid, the suitable reaction conditions were determined as follows: n (Co)/ n (Mn)/ n (Br) = 1/0.04/0.5, n (HMF)/ n (HAC) = 0.05, reaction temperature of 170°C, reaction pressure of 2 MPa, reaction time 40 min, and airflow rate 1.0 L·min −1 . Under these conditions, the yield of the product is 86.01%, the purity is 97.53%, and the loss of the catalytic liquid is about 5.63%, which is at an ideal level and provides a good basis for the recovery of the subsequent catalytic liquid and multiple cycle reactions.
