Nowadays there are several concerns regarding this traditional petroleum-based filler: on one side its environmental footprint is enormous and its production process is no more sustainable and on the other side its price increases annually. For these reasons, sustainable alternative fillers are being studied. In the present research the main waste of the steel industry, namely the steel slag from electric arc furnace (EAF), is investigated as non-conventional filler for a nitrile butadiene rubber matrix (NBR). The slag has been characterized to ensure its safe reuse as filler according to the heavy metals leaching. The slag filled compounds have been characterized and compared to CB filled compounds, in terms of processability by rheometric parameters, mechanical properties, Payne effect, and physicochemical properties to investigate the filler-matrix interaction. From the obtained results, it was shown that EAF slag-filled NBRs are comparable to CB filled NBRs in terms of crosslink kinetics and, when compared at the same hardness level, are comparable in terms of viscosity, stiffness, and elongation at break, while when compared at the same filler volume fraction are similar in terms of compression set and stress relaxation.</p></div>","PeriodicalId":52958,"journal":{"name":"Carbon Resources Conversion","volume":"7 4","pages":"Article 100230"},"PeriodicalIF":6.0,"publicationDate":"2024-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S258891332400019X/pdfft?md5=dedc200f8ca3f915509eb27fb71629f6&pid=1-s2.0-S258891332400019X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139966668","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The development of plastic waste for higher value-added applications instead of landfilling and incineration has received consideration interest in bioenergy and material science research. Herein, a nanoporous carbon support of nickel phosphide catalyst for palm oil hydrotreating was developed from blended polystyrene waste and maize stover via the Co-hydrothermal carbonization (HTC) coupled with the KOH activation process. The Co-HTC parameters, such as temperature, reaction time, and PS percentage, were studied on the properties of co-hydrochar feedstocks for further activation using the Box behnken design. From the comprehensive characterization results, response surface methodology (RSM) results showed that the rising polystyrene proportion significantly exhibited the higher production yield and fixed carbon of co-hydrochar products, an essential characteristic for porous carbon manufacturing. After activation step, the final nanoporous carbon derived from the co-hydrochar (PMPC) exhibited the highest specific surface area of 1033.58 m<sup>2</sup>/g with total pore volume of 0.45 cm<sup>3</sup>/g. Moreover, the PCMC-supported nickel phosphide catalysts were successfully synthesized and tested for the catalytic hydrotreating of palm oil as alternative catalyst. The NiP-PMPC catalyst represents an impressive liquid hydrocarbon yield of 74.68 % with a high green diesel selectivity of 85.92 % at 100 % palm oil conversion.

The compounds were synthesised using a one-pot, three-component reaction. The structures of the synthesised compounds were confirmed using spectroscopic techniques such as FT-IR, 1H NMR, mass spectrometry, and elemental analysis. The antibacterial activity of all the synthesised compounds was tested against <em>Escherichia coli</em> (<em>E. coli</em>) and <em>Bacillus subtilis</em> (<em>B. subtilis</em>), two types of Gram-positive bacteria. The thiamine-pyrophosphate riboswitch <em>E. coli</em> and the purine riboswitch <em>B. subtilis</em> were chosen as targets to determine how compounds bind to them. The molecular docking data showed that compound 6f bound well and had the lowest binding energy in the active site areas of both targets. This was in line with the tests done in vitro. The majority of the compounds have been demonstrated to be antibacterial.</p></div>","PeriodicalId":52958,"journal":{"name":"Carbon Resources Conversion","volume":"7 3","pages":"Article 100222"},"PeriodicalIF":6.0,"publicationDate":"2024-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2588913324000115/pdfft?md5=a37d61cf3cdd97ee42c81f8e8ba242dd&pid=1-s2.0-S2588913324000115-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139454310","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
