The negative dielectric constant appeared for all voltages at frequencies of 103, 102, 10 Hz, proving that the dielectric constant has negative values only at frequencies above one megahertz 106Hz. Also, the dielectric loss has negative values with temperature at all voltages and high frequencies. This structure also has a low dielectric loss tangent from 4 to 50 with all voltages and temperatures and high rectification ratio reach to 1200 times, and high Rj. The performance of dielectric constant, dielectric loss, and dielectric loss tangent depend on the change of frequencies and voltages. The electrical properties of this structure were examined by conventional, dv/dlnI, and the Nord and Cheung method. The ideality factor fluctuates between 3.09 and 3.29, and the barrier height is in the range of 0.56 to 0.58 at room temperature. We found similar results using different methods of measuring the electrical properties. This indicates that the structure is a promising material for preparing diodes, supercapacitor, and high storage devices.","PeriodicalId":504734,"journal":{"name":"ECS Journal of Solid State Science and Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141021679","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}

We investigated the reduction/oxidation of ceria nanoparticles (CNPs) by hydrogen gas-dissolved water (H2 GDW), carbon dioxide gas-dissolved water (CO2 GDW), and oxygen gas-dissolved water (O2 GDW). The concentration of Ce3+ on the CNPs changed from 18.64% to 19.48%, 20.31% to 21.94%, and 21.27% to 19.22%, respectively, after immersion in H2 GDW, CO2 GDW, and O2 GDW for 3 to 12 h. Following the Ce3+ concentration of the CNP surface, adhesion energies between CNPs immersed in H2 GDW, CO2 GDW, and O2 GDW for 6 hours with SiO2 surface were 6.06E-16 J, 6.18E-16 J, and 4.83E-16 J. Cleaning experiments under megasonic conditions revealed the efficacy of H2 GDW and O2 GDW in removing residual CNPs from SiO2 surfaces. The residual cerium (Ce) ion concentrations remaining on the SiO2 film surface after cleaning, were 0.06, 0.41, and 0.10 ppb for H2 GDW, CO2 GDW, and O2 GDW, respectively.","PeriodicalId":504734,"journal":{"name":"ECS Journal of Solid State Science and Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141022842","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 ceramic synthesized using the conventional solid-state route resulted in a single-phase material exhibiting a cubic structure with an Fm-3m space group. The densely packed cylindrical disk of the ceramic was subsequently characterized for its microwave dielectric behaviour in TE01δ mode using the Hakki-Coleman method. The dielectric permittivity (εr) measures 14.4, with a loss factor (tan δ) nearly equal to 4.01×10-4 and a temperature coefficient (τf) of -50.9 ppm/°C. The antenna design was executed using the high-frequency structure simulator design software, utilizing the dielectric ceramic as the resonator, Cu strip as the feedline, and FR4 as the substrate. The maximum energy was coupled to the antenna when the resonator was placed at 11.75 mm on the substrate. The fabricated CDRA, using appropriate simulated parameters, resonated at 7.67 GHz, offering a return loss (S11) of -32.64 dB and an impedance bandwidth of 10.73%. Furthermore, the CDRA displayed a voltage standing wave ratio of 1.04, ensuring a nearby ideal impedance match and a bandwidth of 810 MHz to support high-speed data transmission.","PeriodicalId":504734,"journal":{"name":"ECS Journal of Solid State Science and Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140669703","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}

Calcium cations on nanofiller surface dissociate away from coordinating with silicon-oxygen tetrahedron and infiltrate into void spaces in EP matrix, leaving a larger free volume at filler/matrix interface than in matrix. Calcium cations dissolved in EP matrix adsorbed in the low electrostatic potential region or coordinate with carbonyl groups in EP matrix and thus introduce a miniband of deep electron traps at energy levels >1eV lower than conduction band minimum of the amine-crosslinked EP polymer. Even at room temperature, thermal vibrations can break coordinate bonds between calcium cations and silicon-oxygen framework on calcium-silicate nanofiller surface and make considerable calcium ions infiltrating void spaces within EP matrix, leading to comprehensive improvements of cohesive energy, thermal stability, and charge trapping ability in the calcium-silicate/EP nanocomposite.","PeriodicalId":504734,"journal":{"name":"ECS Journal of Solid State Science and Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140666412","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 major cause of death in COPD patients is due to late diagnosis. Early detection of COPD is crucial for significantly reducing the risk of death but is challenging to attain. A distinguished way to early diagnosis is by using the nanosensor for sensing the COPD breath biomarkers. For the first time, we report an armchair silicene nanoribbon (ASiNR) as a promising sensing material for the diagnosis of hexanal a COPD breath biomarker. In this present study, the density functional theory (DFT) with Grimme D2 corrected approach was incorporated to observe the ground state electronic properties and adsorption mechanism of hexanal on the pristine, defect induced (D) and B-, C-, and N-doped ASiNR systems. N-ASiNR systems show the highest adsorption energy value among previously reported works due to the presence of strong covalent interaction, and it does not show recovery at room temperature. The B-ASiNR system with higher charge transfer exhibits large work function change with the fastest recovery at room temperature in 1.81 s. Our results confirms B-doped ASiNR system acts as an efficient reusable work function-based sensor for the early diagnosis of COPD at room temperature.","PeriodicalId":504734,"journal":{"name":"ECS Journal of Solid State Science and Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140685587","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}

Here, an in-situ generation-carbonization one-step method is proposed to synthesize excellent absorbents based on a common solid waste, willow catkins. The results demonstrate that the microwave absorption performance has been successfully improved owing to the magnetic particles, the core-shell nanoparticles, and the hierarchical porous structure, which results in strong conductivity loss, dielectric loss, magnetic loss, interface polarization, and multiple scattering. The maximum reflection loss (RLmax) reaches up to -50.66 dB and -49.09 dB, respectively, at 16.6 and 17.1 GHz with the thickness of 1.65 mm, resulting in double-peak absorption. What’s more, the effective absorption bandwidth (EAB, RL<−10 dB) can get up to 5.7 GHz (from 12.4 to 18 GHz) with the thickness of 1.84 mm. Great absorption performance can be obtained simply through impregnation and carbonization, which constructs a fruitful and cost-effective paradigm for resource utilization of solid waste such as willow catkins.","PeriodicalId":504734,"journal":{"name":"ECS Journal of Solid State Science and Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140690141","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}
