The growth of plasmonics has been greatly aided by the creation of novel ways for creating metallic nanostructures and a large deal of work on the creation of numerical algorithms to cope with arbitrarily shaped metallic nanostructures. The LSPR and field enhancement of an Al nano-star were the main topics of this paper. A larger RIS factor is obtained after adjusting the refractive index sensitivity parameter, making it appropriate for refractive index-based sensor nanostructures.\u0000\u0000\u0000\u0000This study's primary goal is to provide a comparative analysis of the refractive index sensitivity factor for Al nanostars dependent on their size and number of arms.\u0000\u0000\u0000\u0000Al nano star's LSPR and field enhancement have been assessed using the Finite Difference Time Domain (FDTD).\u0000\u0000\u0000\u0000By altering the size and number of arms of the nano star, the tenability of the plasmonic peak has been assessed, and it has been found that the peak is sensitive to the ambient dielectric constant. A study has been done on the refractive index sensitivity parameter. A higher sensitivity of about 370 nm/RIU, which is significantly higher than that of other metallic Nanostar (NS), is seen after adjusting the size and number of arms. A wide range of applications is covered by the Al NS field enhancement pattern, which exhibits stronger enhancement with no aggregation at the plasmon peak.\u0000\u0000\u0000\u0000For LSPR sensing applications, the impact of modifying the environmental dielectric constant is examined. By changing the size and quantity of the Al NS's arms, we were able to compare the refractive index sensitivity parameter. The bigger size NS exhibits more peaks due to the contribution of the multipole; however, after tuning a number of parameters, better sensitivity in comparison to Au and Ag nanostar has been attained. Al NS can therefore be a promising sensing material for refractive index sensing employing LSPR properties.\u0000","PeriodicalId":38913,"journal":{"name":"Nanoscience and Nanotechnology - Asia","volume":"65 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73541863","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 the present study, the synthesized TiO2 nanotubes (TNT) from Ti-6Al-4V alloy, which were left unattended and exposed to environmental conditions (i.e., humidity and ambient temperature) for more than 4 years, were investigated to underline any important alteration/changes and ageing effects, on the surface morphology, the surface composition, and the electrochemical behaviour.\u0000The nanotubes were made in 2018 by anodization in different potentials (20V, 40V, 50V, and 60V) for different times (30 min, 60 min, 90 min, 150 min and 180 min) in an Ethylene Glycol solution for other purposes.\u0000\u0000\u0000\u0000For the surface morphology characterisation, electronic microscopy (SEM) was performed to depict any tendency with anodization conditions: potential and time.

The EDXS spectra analysis was realised to investigate the storage time impact on structure surface stability. A drastic decrease in the amount of oxygen was noticed on all of the surfaces where wettability measurements by contact angle were performed to confirm the latter.
