In Fourier-transform infrared spectroscopy spectrum, the characteristic signal was observed at 3,262 cm−1 belonging to the OH group. The crystal structure of nanoparticles was revealed by X-ray diffraction analysis. The diffraction peaks (2θ) can be indexed to 111, 200, 220, 311, and 222 components representing the face-centered cubic unit structure. The spherical particle size was calculated as 18.1 nm by transmission electron microscopy. Cytotoxic effects of extract and AgNPs@Org were executed by MTT assay using Capan-1, L929, and Caco-2 cell lines. AgNPs@Org exhibited the excellent cytotoxic effect on Capan-1 cell lines with the viability of 37.6% (0.5 µg·mL−1).

The gum TGC not only qualifies the principles of green chemistry but also embraces unique qualities. In this perspective, the current review concentrates on the composition, uses, and exploitation of gum towards synthesizing metal NP of silver (Ag), gold (Au), palladium (Pd), platinum (Pt), and their characterization (UV-visible absorption spectroscopy, X-ray diffraction, Fourier transform infrared spectroscopy, and transmission electron microscopy). In addition, applications of synthesized NP as a bactericide, catalyst, antioxidant, and peroxidase mimic are emphasized. Ag NP (13 nm) showed antibacterial action against Gram-negative and Gram-positive bacteria at 2–12 μg‧mL−1. The exploitation of Ag NP as a bactericide makes it a candidate of choice for medicinal and pharmacological applications. The catalytic activity of Pd NP (14 nm) demonstrated borohydride reduction of methylene blue. The gum reduced/capped metal and metal oxide NP serve as redox and photocatalysts for the remediation of toxic pigments and dyes in industrial effluents. At 15 μg‧mL−1, Pd NP exhibited 1,1-diphenyl-2-picrylhydrazyle radical scavenging activity (95.8%) and served as an artificial enzyme mimic for colorimetric sensing of hydrogen peroxide. The industrial applications of other TGC-based nanocomposites, such as heavy metal sorption, wound dressing, drug carrier, tissue engineering, etc., are mentioned.","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":"44404451","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 results show that the modification mechanism of both the natural asphalt and petroleum asphalt is mainly a physical blending process. The polar functional groups contained in natural asphalt make modified asphalt with natural asphalt have characteristic good scaling resistance and water stability. Subsequently, the carbon emissions of each link of asphalt production stage were quantified, and the influence of mining, transportation, and processing on the total carbon emissions were all analyzed by establishing the carbon emission calculation model of asphalt production. The calculation results of GREET model showed that the equivalent carbon dioxide emission (CO2e) of rock asphalt mining was only 9.4% of that of crude oil production. At the same time, the CO2e of modified asphalt with natural asphalt processing was 44.7% lower than that of petroleum asphalt, and the carbon emission of rock asphalt transportation accounted for only 1/3 of that of petroleum asphalt transportation. Furthermore, the increased energy consumption caused by petroleum asphalt transportation and modified asphalt with natural asphalt processing will partially offset the contribution of natural asphalt to reducing carbon emissions. Meanwhile, the CO2e of modified asphalt with natural asphalt was lower than that of petroleum asphalt when the content of natural asphalt exceeded 18%. Thereafter, the analytic hierarchy process calculation results showed that petroleum asphalt processing and transportation had the largest weight of carbon emissions in the production stage of modified asphalt with natural asphalt. Ultimately, it is significant to further reduce carbon emissions by increasing the content of natural asphalt, which will then inevitably lead to the reduction in the production and transportation energy consumption of petroleum asphalt.","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":"43841629","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}

Because the properties of graphene are closely related to their structural parameters, graphene with different size distributions is suitable for different applications. However, current methods of fine-scale separation of graphene and its derivatives have certain limitations. In this study, graphene oxide (GO) size separation using multilayer dialysis was proposed. Multiple size separation in one step was achieved by customizing the dialysis size of each layer according to the actual requirements. In this way, GOs of different sizes were separated and large-scale synthesis can be achieved using this method. Meanwhile, the anti-friction and lubrication properties of aqueous dispersion solutions of GOs of different sizes were investigated. The results indicated significant improvements of the anti-friction and lubrication properties of GO samples prepared by the proposed method, as large-scale GOs can act as lubricants by relieving, if not preventing, friction between the two friction surfaces.","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":"135445367","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}

Copper nanoparticles have considerable potential for reducing the environment’s harmful pigments and nitrogen contaminants.

Ultraviolet spectroscopic, transmission electron microscopy (TEM), and X-ray crystallography (XRD) techniques were used to evaluate the produced oxidized copper nanocrystals. The particles produced have been very robust, are cylindrical in form, and have an outer diameter of 12 nm. Furthermore, under normal conditions, copper oxide (CuO) nanomaterials demonstrated strong photocatalytic efficiency in liquid media for the oxidation of Congo red, bromothymol blue, and 4-nitrophenol in an acidic solution acetic anhydride. Moreover, the CuO nanocrystalline enzyme could be readily vortexed or used for five cycles with an exchange rate of even over 90%. The evaporation process caused around 18% of the loss of weight between 25°C and 190°C, while soil organic breakdown caused almost 31% of the loss of weight around 700°C. As a result, the little reduction in enzymatic effectiveness of the recoverable multilayer CuO substrate might be attributed to catalytic degradation throughout spinning and processing.","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":"42868689","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 develop a feeding strategy for PHA production in a large-scale FBBR, an optimization-based control scheme that considers nutrient dispersion is proposed in this work. A coupled partial differential equations and ordinary differential equation model is proposed to describe the axial-dispersed nutrient and well-dispersed microbial dynamics with process constraints. An analytical model predictive control (AMPC) method that applies integrated variables of nutrients is employed to develop the real-time control system. The control objective is to regulate the PHA concentration at the updated set points by adjusting the nutrient feed rates; a process disturbance is introduced to evaluate the control robustness. Simulation experiments of a fed-batch operation are conducted to investigate the performance of the developed controller; the controlled output is designed to track the updated set points corresponding to the biomass concentration. Results of closed-loop and regulatory systems showed that the proposed control strategy could provide more productivity (33–38%) compared to the applied PI controller. The performance test demonstrates that the developed control system could apply the biomass concentration for updating set points, provide the optimal control actions that promote PHB accumulation and handle the disturbance effectively.","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":"44817649","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}

From the optimization experiments, it was found that the extraction using the MW irradiation at 300 W for 3 min produced the extract with high and reproducible brazilin content which could be readily used for the synthesis of AuNPs. Under the optimal synthesis conditions, roughly spherical CS-AuNPs with an average diameter size of 49.6 nm and acceptable 28-day stability were obtained within only 1 min. The resulting CS-AuNPs were capable of selective binding to Fe2+, Fe3+, and Al3+, leading to particle aggregation as well as noticeable change of color and shift of UV-Vis absorption maxima. From these results, CS-AuNPs could be fabricated via this fast, green, and efficient route.
