Current treatment approaches, such as surgery, chemotherapy, and radiotherapy, encounter significant difficulties due to the heterogeneous and intricate regulation of tumors. Nanotechnology, especially the utilization of graphene oxide (GO), presents a promising approach to overcoming the limitations of traditional treatments. GO's unique properties, including its two-dimensional structure, functional groups, and high surface area, make it an ideal material for developing multifunctional nanocarriers. Graphene oxide-based nanocarriers have demonstrated immense potential in breast cancer therapeutics by overcoming the limitations and adverse reactions associated with chemotherapy. The functionalization of GO's surface using biocompatible substances like chitosan and polyethylene glycol improves the cytotoxicity of GO. Enhancing the cytotoxicity also improves the ability to treat tumors that have developed resistance to traditional treatments. These findings demonstrate the promising efficacy of GO-based nanocarriers in treating breast cancer and pave the way for the development of more precise and efficient treatment strategies in the future, potentially improving therapeutic outcomes.\u0000","PeriodicalId":14116,"journal":{"name":"International Journal of Materials Science and Applications","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141388763","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They have the advantage of being biodegradable and sometimes less expensive. To this end, the use of packaging with the function of hot preservatives but made from local and biodegradable materials is a very interesting alternative to synthetic enclosures. This work involved formulating eco-materials made from cow dung coatings and a mixture of cow dung coatings with a framework of fibres extracted from the stalks of oil palm leaves. In addition, to monitor the temperature rise in the various eco-materials manufactured and characterise them using the hot ribbon method to determine their effusivity and thermal conductivity. The pair of materials exposed to heating showed a gradual rise in temperature within the materials when the resistor was energised. A slightly faster rise was observed in the first fifty minutes. The results obtained indicate that the cow dung has a higher effusivity (E = 517.32 J.m-2. °C-1. s-1/2) than its composite (E = 501.20 J.m-2. °C-1. s-1/2). The thermal conductivity values obtained indicate that the cow dung has a higher thermal conductivity (λ'=0.19 W.m^(-1).K^(-1)) than that of the composite structure (λ=0.15 W.m^(-1).K^(-1)). From the above, the presence of the fibre frame has the effect of reducing thermal conductivity because it absorbs more energy. The materials produced therefore have proven insulating properties, which are improved when the framework is made from fibres extracted from the stalks of oil palm leaves. Using oil palm fibres in combination with cow dung as eco-materials for thermal insulation is an excellent alternative to synthetic insulation.\u0000","PeriodicalId":14116,"journal":{"name":"International Journal of Materials Science and Applications","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140992439","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

If their potentials for industrial application could be exploited, selling the fibers for manufacturing uses would be a win-win situation for both the industries and the farmers, and provide the latter with a much needed source of additional income since composite material reinforced with lignocellulose fibers can be used for diverse application including the production of parts in automotive industry. For this to be successful, it is mandatory to make fiber level characterization. In this process, there are various determinants that affects the characteristics of lignocellulose fiber including agro-ecological zone, plant age from which the fiber is extracted, lignocellulose structure, fiber extraction method and subsequent treatment to enhance properties. This review, therefore, presents the basics of lignocellulose fiber potential and insight into selected deliberation related to fiber level characterization in light of micromechanical analysis for new biocomposite under development. Included in this review, there are considerations to be potted during characterization at fiber level. For fiber diameter measurement and estimation, the following considerations are reported in this paper: measurement method validation, proper cross-section and fiber geometry assumption, lignocellulose structure and internal holes; enough sample consideration, incorporation of analytical method for cross checking. Likewise consideration during estimating fiber density, single fiber tensile strength and stiffness are review and discussed in this review.","PeriodicalId":14116,"journal":{"name":"International Journal of Materials Science and Applications","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140693402","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to create a uniform coating with optimal thickness, the effective parameters of Electrospinning coating, including solvent, polymer concentration, and bioceramic percentage, were investigated. Also, the cytotoxicity and corrosion tests were evaluated by the electrochemical polarization test method of the created coating in comparisons and different percentages. In order to characterize the coating, a test such as a scanning electron microscope was used. The results showed that as much as the amount of Graphene oxide is increased, the diameter of Nanofibers decreases. The diameter of Polycaprolactone Nanofibers was 1.3 micrometers, which increases to 56.0 micrometers by adding Graphene oxide. The results of the corrosion test showed that the use of Nano composite coating increased the corrosion resistance to the size of the coating. The nanocomposite coating consists of polycaprolactone nanofibers and graphene oxide, which mimics the behavior of the extracellular matrix and improves the biological and antibacterial behavior of the titanium surface. So far, there has been no report on the creation of this fibrous nanocomposite coating on titanium. The results of the cytotoxicity test showed that the use of Nanocomposite coating has effectively reduced the cytotoxicity on the scaffolds. By creating a polycaprolactone-graphene oxide nanofiber composite coating, the biological and antibacterial properties of titanium alloy will be improved and its corrosion resistance will probably change. In this project, the main question is extracting effective parameters in creating a composite coating on titanium surface by electrospinning method and characterizing and biological evaluation of the created coating.","PeriodicalId":14116,"journal":{"name":"International Journal of Materials Science and Applications","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140752833","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
