However, industrial production of these particles is difficult, complicated, and dependent on a variety of physical characteristics such as temperature and infrastructure availability. This research describes an instant industrial method for producing titania nanoparticles using a wet chemical sol-gel synthesis. X-ray diffractogram (XRD) and Fourier transform infrared spectroscopy (FTIR) analysis of as-synthesized titania nanoparticles revealed a strong diffraction peak at Bragg angle 25  , which can be attributed to the titania anatase phase, and vibration bonds at 463 cm – 1 , which confirms the presence of titania. The morphology of these titania nanoparticles was examined using a field emission scanning electron microscope (FESEM), which determined the particle size to be around 37 nm. Using diffuse reflectance spectroscopy (DRS), the optical properties of the as-synthesized nanoparticles were studied, and their band gap was determined to be 3.37 eV. At room temperature, the dielectric constant and loss of titania nanoparticles were measured as a function of frequency. Additionally, titania particles were mixed into transformer oil to assess its dielectric breakdown strength for better insulating properties.","PeriodicalId":16654,"journal":{"name":"Journal of Nano-and electronic Physics","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68046465","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}

The millimeter-wave (mm-wave) and sub-6 GHz bands are integrated into the new antenna system which is suggested for the 5G handheld devices. The suggested antenna is a single antenna system that covers a 32.4 GHz bandwidth from 5.8 GHz to 38.2 GHz. The intended antenna structure has been obtained by introducing T-Shaped slots in the patch along with presence of parasitic elements on either side. The antenna's FR-4 substrate is developed with dimensions of 30  28  1.6 mm 2 . The gain varies be-tween 5 and 32 dBi across the operating frequency. The parasitic components are designed and connected with the patch to support the patch's ability to radiate with multiple resonances over a wide operating band. The optimal antenna includes six resonant frequencies 11 GHz, 18.2 GHz, 20.3 GHz, 21.7 GHz, 23.2 GHz, and 27 GHz. During the entire working frequency, the Voltage Standing Wave Ratio (VSWR) is obtained below 2, which signifies well impedance matching. The antenna maintains an efficiency of at least 65 % throughout, making it a strong candidate for 5G devices. The novel antenna geometry with compact size, wide operating band with multiple fruitful resonant frequencies, high gain, good radiation efficiency, omni-directional stable radiation patterns are the major findings reported in this article.","PeriodicalId":16654,"journal":{"name":"Journal of Nano-and electronic Physics","volume":"298 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135698828","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}

Concrete's interior relative humidity influences its strength and longevity. In the process of internal curing concrete along with the surface moisture, extra internal moisture is provided so that self-desiccation or dehydration can be avoided. In this paper, biomaterial extract is used to examine the performance of internally cured concrete and is compared with the performance of air-cured and conventionally cured concrete. The dosages of biomaterial extract used as internal curing agents are 0.0 %, 0.20 %, 0.40 %, 0.60 %, 0.80 %, and 1.0 % by weight of cement. This manuscript focuses on the compressive power of M-20 grade concrete and using Biomaterial extract as an internal curing agent determined for 3, 7, and 28 days and compared with air-cured and traditional cured cement concrete respectively. From the experimental test results and observations, the compressive potency of M-20 grade tangible enhances with a boost in dosages of extract of biomaterial up to 0.60% by weight of cement, if the dosage increased more than 0.60 % compressive strength decreases. The results are optimistic in bio-self-cured concrete which is environmentally friendly and low-cost and also improves the level of hydration.","PeriodicalId":16654,"journal":{"name":"Journal of Nano-and electronic Physics","volume":"278 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135699109","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 generate the wideband width of 26-70 GHz a proposed antenna is designed. The design composed of rectangular patch antenna with edge-cut technique (making slots at the corner of the patch) and introduced on partial ground plane for an improved impedance matching. The suggested microstrip antenna (proposed antenna) has been designed and examined on Rogers RT5880 substrate with dimensions 10 mm  10 mm with dielectric constant 2.2, loss tangent 0.0009 and thickness of 1.57 mm using computer simulation tool (CST) software 2019. The results reveal that the antenna shows a return loss under – 10 dB over a range from 26-70 GHz and resonated at multiple frequencies 29 GHz, 32.8 GHz, 42 GHz, 47 GHz, 56.6 GHz, and 66 GHz.
