However, the exposure of the steel to acids such as hydrochloric acid (HCl) accelerates its corrosion rate. Green organic corrosion inhibitors are among the most effective materials to reduce the mild steel corrosion rate in an acidic medium. These inhibitors are environmentally accepted, easy to extract, and non-toxic. This study investigates the feasibility of using different green Jordanian natural agro-wastes as green organic corrosion inhibitors and determines the efficiency of these inhibitors at different concentrations at room temperature. The potentiodynamic polarization test was used in two sets of runs; the first set of runs was used to screen ten extracted green inhibitors and choose three based on their highest efficiency. In the second set of runs, the test was performed only for the highest efficiency inhibitors selected from the first run. A weight-loss and Fourier-transform infrared spectroscopy test was also performed for the selected inhibitors. The results of the tests indicate that the green Zucchini (Cucurbita pepo) leaf extract (CPLE), Oak (Quercus) leaf extracts (QLE), and Okra (Abelmoschus esculentus) leaf extracts (AELE) were the selected inhibitors.","PeriodicalId":12929,"journal":{"name":"Green Materials","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2023-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48955054","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For the manufacture of cement, limestone is the key component that is the major source of carbon dioxide (CO2) emission. Moreover, local municipalities all over the world have long been concerned about the disposal of sewage sludge. Larger quantity of sewage sludge generation is becoming an urgent alternative solution for sludge disposal and waste recycling in construction materials. In accordance with the concept of sustainability, low carbon cement is produced in the current study by blending sewage sludge ash (SSA) and carbide lime sludge (CLS) (industrial waste) with Ordinary Portland Cement (OPC). In terms of physical properties, the influence of low carbon cement containing different percentages of SSA with 10% CLS is compared with composite cement containing fly ash (FA) in different percentages addition with 10% CLS. The outcome from the study shows that the utilization of SSA with CLS up to 45% would be possible with OPC as it indicates an acceptable level of compressive strength, conservation of depleting limestone reserves, saving in thermal and electrical energy besides emissions reduction of CO2.","PeriodicalId":12929,"journal":{"name":"Green Materials","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2023-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42791394","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, the coconut fiber (CF) surface was enriched via four kinds of modification routes including mercerization, amino-functional silane treatment, bio-based epoxy resin sizing, and isocyanate treatment to enhance its interfacial adhesion to thermoplastic polyurethane (TPU) matrix. Tensile strength and Shore-hardness parameters of composites were improved by surface-modified CF inclusions. Thermo-mechanical response of TPU was optimized after CF loadings regardless of treatment type. Composite involving silane-modified CF exhibited the lowest water uptake due to the hydrophobic behavior of the silane layer. The increase in interfacial interaction between the TPU matrix and modified CF was confirmed by SEM investigations. The chemically enriched surface of CF confers the performance of composites thanks to improved adhesion in the TPU-CF interface.","PeriodicalId":12929,"journal":{"name":"Green Materials","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2023-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42847123","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among the emerging technologies stands out one that uses sodium (Na+) and iron ions. Sodium iron oxide (NaFeO2) has polymorphism, with only the α phase being active for the reversible deintercalation of sodium ions, so this phase has potential application as an electroactive material in green sodium-ion batteries. The novel synthesis of α-sodium iron oxide through the sol–gel route, which provides a material with small particles and high crystallinity, is described in this work. Through X-ray diffraction and Rietveld refinement, it was found that the initial chelating agent/metals ratio affects the concentration of the α and β phases at the end of the synthetic route. The α-sodium iron oxide, obtained with an appropriate chelating agent/metals ratio, showed high purity and crystallinity. A discharge capacity of approximately 110 mAh/g was achieved when the α-sodium iron oxide electrode, obtained through the sol–gel route, was cycled from 1.00 to 4.00 V against sodium ions/sodium (Na), corresponding to the intercalation of approximately 0.5 sodium ions of the Na1−x FeO2 formula. The success of the synthesis of the α-sodium iron oxide phase can lower the cost and ensure the economic viability of green sodium-ion batteries.","PeriodicalId":12929,"journal":{"name":"Green Materials","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2023-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42916708","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
