X-ray diffraction spectra confirm that all the samples have a tetragonal structure. Electronic distribution over the unit cell of Sn1−x\u0000 Fe\u0000 x\u0000 O2 showed the dependence of electronic density on the x. The crystallite size of the obtained samples was in the range of 42–72 nm. Impedance spectroscopy was employed to investigate the variation of the electrical impedance and some related parameters as frequency functions in the range of 75 k Hz–10 MHz at room temperature. The dielectric behavior was explained using the Maxwell–Wagner model of interfacial polarization. The ac conductivity results were used to evaluate the maximum barrier height, the minimum hopping distance, and the density of the localized states at the Fermi level. The effect of adding the iron ion into the tin dioxide compound was apparent, as the electrical and magnetic properties as well as the morphology were affected, although the crystal structure phase still has the same tetragonal crystal system for the different iron concentration (Fe from x = 0 up to x = 0.04) with slight variation in the lattice constants. The magnetic measurements illustrated that the Fe-doped SnO2 nanoparticles exhibit ferromagnetic ordering at room temperature. Variation of the Fe content affects the ferromagnetic characteristics of the samples.","PeriodicalId":14079,"journal":{"name":"International Journal of Materials Research","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2024-02-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140408647","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}

Available anticancer drugs used in chemotherapy are associated with severe side effects due to high dosage requirements. Electrospun nanofibers have an extensive surface area, controllable pore size, and tunable drug release profiles, which make these nanofibers promising candidates in the medical field. Electrospun fibrous matrices are increasingly used in cancer research as patches for drug delivery in living organisms and as scaffolds for cancer modeling in the lab. Towards these applications, nanofibers synthesized by electrospinning have exhibited great clinical potential as a biomimetic tumor microenvironment model for drug screening, a controllable platform for localized, prolonged drug release for cancer therapy, and a human cancer diagnostic tool for capture and isolation of circulating tumor cells in the bloodstream and detection of cancer-associated biomarkers. This review briefly describes most of the materials used in electrospinning. Then, we discuss two ways that electrospinning is used to fight cancer: first, as patches with anticancer agents for therapeutic cargo delivery, and second, as three-dimensional fiber for filtering and detecting cancers.","PeriodicalId":14079,"journal":{"name":"International Journal of Materials Research","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2024-02-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140413012","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}

When biomaterials are utilised as templates in the creation of inorganic materials, they can lead to constructed mesostructures via cost-effective and environmentally friendly synthetic pathways. Based on this context, the goal of this study was to assess the impact of palm oil on the surface properties and crystallite characteristics of titania nanoparticles. In this work, the various physico-chemical parameters such as thermal, surface area, porosity, crystallinity, chemical composition, textural and morphological characteristics of the palm oil (PO) templated titania were studied using various analysis techniques. Palm oil templated titania samples were synthesised using various amounts of palm oil as templates. The sample generated with a molar ratio of PO over titania precursor of 0.07 possessed large surface area (74.5 m2 g−1), small particle size (13.4 nm), uniformly dispersed spherical particles with good morphology and porosity among the various templated titania produced in this work. In addition, it was found to possess maximum photocatalytic efficiency in degrading the target 4-chlorophenol under UV irradiation.","PeriodicalId":14079,"journal":{"name":"International Journal of Materials Research","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2024-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140419946","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}
