Current approaches to control corrosion have some paucity of efficiency which triggers the search for novel materials that are green, cheap, and made from renewable resources. In this study, an attempt was made to prepare Acacia auriculiformis seed oil (ASO) based fatty amide (AFAM) through a simple reaction route involving aminolysis of ASO fatty acid (AFA) and diethylenetriamine (DETA). FTIR and 1HNMR were used to determine the structural characterisation of the synthesised amide. Properties like acid value, amine value, refractive index, and specific gravity were measured. The coating films were prepared by using a standard formulation, in which synthesised fatty amide was added in different proportions. The performance of the cured films was evaluated and compared. The hydrophobicity test reveals that the hydrophobicity of film increases with the addition of fatty amide up to 2% then decreases. The effect of the synthesised product on mild steel was investigated as per the standard protocol. The results revealed that developed fatty amide inhibits the corrosion of carbon steel up to a certain concentration (2%) in the film.","PeriodicalId":12929,"journal":{"name":"Green Materials","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2024-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141337722","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}

Cocoon waste, including damaged or uncoiled cocoons and those with pupae, is recognized as an eco-friendly choice. This study aims to develop and assess the incorporation of varying amounts of cocoon waste as reinforcement in epoxy resin matrix composites through the cold pressing process. The cocoon waste content in the composite specimens ranged from 0 – 40 wt%. Tensile testing and ballistic impact testing were conducted to evaluate specimen performance. The cocoon waste composite plate exhibited a maximum tensile strength of 62.21 MPa at 30 wt%, slightly surpassing that of woven hemp. These findings indicate the advantageous reinforcement attributes of cocoon waste. However, a limitation was identified: bullets fully penetrated the composite plate. To address this, ultra-high-molecular-weight polyethylene was incorporated in cocoon waste composite, resulting in enhanced tensile strength (107.36 MPa) and complete bullet penetration prevention. These outcomes position the study as a promising avenue for developing body armour plates meeting the stringent Level II certification standards set by the National Institute of Justice.","PeriodicalId":12929,"journal":{"name":"Green Materials","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2024-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141340154","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}

Additionally, one of the most crucial ways to increase drilling efficiency since environmental rules were passed is by finding an inexpensive and ecologically acceptable drilling fluid additive. Pomegranate peel extract (PP) and PP modified by AlCl3 (PPA) were created in this study. Their effects on inhibiting clay swelling were evaluated by linear swelling test, mud ball test, anti-swelling test and drilling fluid performance evaluation. The performance of the modified pomegranate peel extract on inhibiting clay swelling was compared with that of KCl. The swelling rate of bentonite was effectively reduced by 1.20% PP, which represented a substantial improvement above 4% KCl. The results of this study indicated that PPA has excellent performance in inhibiting clay swelling compared to known inhibitors. PP was modified by 0.06% AlCl3 (named as PPA-1). The YP/PV remained basically stable after the addition of PPA-1 to the drilling fluid in the 100°C hot rolling experiment. Thus the drilling fluid showed good rheological properties. And the drilling fluid prepared with PPA-1 has a high shale recovery rate. Finally, the correlation between the molecular structure of PP and PPA-1 and its inhibition mechanism was assessed by XRD and IR. This study provides a pathway for converting low-cost agricultural by-products into high value-added industrial materials.","PeriodicalId":12929,"journal":{"name":"Green Materials","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2024-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141338655","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}

Sustainable resource utilization in industrial sectors including infrastructure and building sector shall address the shared challenges. Concept of circular construction materials can be a game changer and catchment to industrial sustainability. The objective of the study is to develop Eco epo-seal, ancillary construction material without incorporating conventional materials. Discarded mine waste (DMW), Industrial by-products Porous Fine Aggregate Like (PFAL) and Iron and Steel Waste (ISW), epoxy was employed in the preparation. A total of 36 compositions were attempted by varying DMW (7-27%), PFAL (37-81%), ISW (0-12%) and epoxy (10-30%). The Eco epo-seal was tested for consistency, density, water absorption (WA) (Normal- N, Long term -LT, Long term alkaline- LA), porosity, compressive strength (CS) (N, LT, LA), Flexural strength (FS) and Ultrasonic pulse velocity (UPV). Performance of the Eco epo-seal was reported as density (1065.2 Kg/m3 (B1) to 1763 Kg/m3 (W3)), WA (0.23 % (W1- N) to 68.07% (B3- LA)), porosity (0.0037 (Z3) to 0.479 (A2)), CS (2.36 MPa (A3- N) to 39.44 MPa (W1- LA)), FS (0.41 MPa (Q2)-15.64 MPa (W1)) and UPV (0.8 Km/s (B3) to 2.58 Km/s (W1)). Among the raw materials of Eco epo-seal, epoxy content greatly influences the performance in normal medium. In comparison of performance of Eco epo-seal in LT condition and LA environment over normal medium, enhanced performance is observed with higher epoxy content and deteriorates for lower epoxy content. Multiple linear regression using principal component analysis was employed to model the performance. Porosity, WA and CS of Eco epo-seal varies linearly and FS follows a nonlinear trend. Eco epo-seal is a versatile composite suitable for various civil engineering and building applications, circular approach adopted is a one-step solution to prevailing waste management issues and places construction industry as a forerunner in cleaner practices of Industry 5.0.","PeriodicalId":12929,"journal":{"name":"Green Materials","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2024-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141364488","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}

This work focuses on the improvement of its viscoelastic performance by using natural sand particles as fillers. Experiments are carried out to investigate the static and dynamic viscoelastic properties of epoxy with various sand particles content. Static mechanical tests demonstrated an increase in the elastic modulus, albeit at the cost of reduced strength at higher sand content due to stress concentrations. Dynamic tests indicated substantially improved storage modulus and damping of epoxy after being filled with the sand particles. Moreover, the glass transition temperature of the epoxy shows a substantial rise upon the addition of sand particles, signifying an augmentation in its heat resistance. Static viscoelastic characterization revealed an elevation in both room and high-temperature relaxation moduli upon incorporating sand. By applying time-temperature superposition principles, long-term relaxation curves are obtained, which can provide a reference for engineering design. These viscoelastic investigations offer insights into the underpinning mechanisms governing the performance of sand-reinforced epoxy. This enables the rational design of sand particle reinforced epoxy for customized durability, heat resistance, and vibration damping.","PeriodicalId":12929,"journal":{"name":"Green Materials","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2024-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140999440","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}
