Influence of Ni2+ ions on structural, spectral and dielectric properties of Sr–Co spinel ferrites synthesized by sol-gel auto-combustion route

Nickel substituted Sr–Co nano spinel ferrites with composition Sr0.5-xNixCo0.5Fe2O4 (0.0, 0.1, 0.2, and 0.3) were prepared with the help of a sol-gel auto combustion route. The prepared materials were sintered at 800 for four and a half hours. Analysis of XRD confirmed that the material is composed of a cubic spinel structure with a single phase, and its space group is Fd-3m. Rietveld refinement of X-ray diffraction data was done for all prepared compositions using FULLPROF software. As the composition under study contains more nickel than lattice constant, crystalline size, X-ray density, and bulk density decrease. The dielectric properties were observed about frequency. The dielectric properties revealed that dielectric loss, dielectric constant, and ac conductivity decrease with increasing the Ni2+ content. The activation energy (ΔE) was calculated from the slope of Arrhenius plots. The ΔE found in the range of 0.580–0.096 eV. The analysis of XPS was carried out to examine the elemental state of annealed samples. The prepared material is suitable for employment in applications involving high frequencies because the Ni-doped Sr–Co ferrites with the greatest Ni2+ concentration have the lowest dielectric loss, dielectric constant, and tangent loss value.

Strain-induced changes in the electronic, optical and mechanical properties of the inorganic cubic halide perovskite Sr3PBr3 with FP-DFT

In recent years, inorganic perovskite materials have garnered significant attention in solar technology due to their outstanding structural, optical, mechanical, and electronic properties. A comprehensive investigation, employing first-principles density-functional theory, was conducted to assess the impact of compressive and tensile strain on the optical and electrical properties of cubic perovskite Sr3PBr3. The unstrained Sr3PBr3 exhibits a direct bandgap of 1.528 eV/2.32 eV with PBE/HSE functions at the Γ point. Under compressive strain, the bandgap decreases (1.23 eV at −4% strain), leading to a redshift in the absorption coefficient spikes, while tensile strain results in a slight bandgap increase (1.723 eV at +4 % strain) and a blueshift in absorption coefficient spikes. Total density of states was computed as 18.75 and 1.60 electrons/eV at VB and CB without strain. The value of static dielectric constant was measured as 5.24. The initial critical point of dielectric constant, large absorption peak, and maximum loss function were calculated at 1.47, 7.28, and 9.15 eV without strain. The material demonstrates excellent light absorption in the range of visible light, aligning with its electronic properties. The Sr3PBr3 perovskite is therefore thought to be perfect for usage in solar cells for the generation of power and light control.

Optimization of an innovative hybrid approach ZnO-Doped PVP nanofibers for electrical devices applications

The solid solution of pure ZnO nanoparticles and doped Polyvinylepyrrolidone (PVP) green hybrid nanomaterial’s synthesized by using the electro spinning method. The synthetic polymer matrix nonwoven fibrous mats containing innovative properties are shown to shrink and encapsulated the zinc oxide materials to change the surface morphology when the concentration of PVP is increased from 1 % to 2 % dopants. The crystalline nature and morphological studies were examined by using x-ray diffraction and a scanning electron microscope. The average crystallite sizes of easily formed ZnO nanoparticles and nanorods that are 21 nm and 62 nm respectively. Moreover, the electrical and optical properties of the fibrous mesh were determined by using electrical impedance analyzer. The electrical conductivity values were measured in the pure ZnO nanoparticles in contrast to the doped ZnO/PVP. The tangent loss, dielectric constant, capacitance and relaxation time values are revealed in this study. All the characterization has been carried out at room temperature. The relaxation time for 1 %, and 2 % ZnO/PVP is (0.8 ns) and (0.79 ns) respectively which is suitable for the application of trigger using devices. The overall findings of this study implemented in a wide range of technologies i.e. photonics, electronics and super capacitor devices etc.

Temperature Dependence of the Dielectric Constant on the Lunar Surface Based on Mini-RF and Diviner Observations

Radar observation is an effective way to understand subsurface structures in terms of the dielectric constant, whose controlling factors include chemical composition, packing density, and water/ice content. Recently, laboratory measurements have shown that the dielectric constant of lunar regolith simulants also depends on the temperature, which has never been evaluated from remote sensing data. In this study, we estimated the dielectric constant from the Miniature Radio Frequency (Mini-RF) data on a lunar crater floor in the north polar region at two different local times (i.e., different surface temperatures). We calculated the dielectric constant using the inversion method and obtained the bolometric surface temperature from the Diviner Lunar Radiometer Experiment (Diviner) data. The histograms of the estimated dielectric constant values are different between the two local times. This could be interpreted as a result of the temperature dependence of the dielectric constant, while further evaluation of the influence of topography on the incidence angle and small surface roughness is needed. Nevertheless, our result suggests that the temperature dependence of the dielectric constant should be considered when interpreting S-band radar observations of the Moon and other celestial bodies with large surface temperature differences.

Optimizing dielectric constants for enhanced performance in nanoscale DG-FinFETs: A comprehensive study on short channel effects

This study explores how variations in fin and gate dielectric constants impact nanoscale, DG-FinFETs’ sensitivity to Short Channel Effects (SCEs). Various fin (channel) materials; Gallium Arsenide (GaAs), Gallium Antimonide (GaSb), Gallium Nitride (GaN), and Silicon (Si), are considered. PADRE simulation environment is used to investigate the threshold Voltage (Vth) Roll-off, a crucial performance parameter. GaAs-FinFET, with a gate dielectric and fin dielectric constant values of 15 and 45 shows the lowest threshold voltage of 0.412 V. The study concludes that FinFETs with a higher fin dielectric constant than gate dielectric constant exhibit reduced SCEs, leading to lower power consumption, faster switching, and improved efficiency. This underscores the importance of optimizing dielectric constants, especially the fin dielectric constant, for enhanced DG-FinFET performance.

The proposed antenna is simulated, fabricated, and experimentally tested.

Effect of Microwave Radiation on Tobacco (Nicotiana tabacum) Using VSWR Method

The values of dielectric constant (ε'p), dielectric loss (ε"p), relaxation time ( p) and conductivity ( p) of the sample were measured for different packing densities at 9.85 GHz microwave frequency and different temperature (200C, 35°C and 500C). Complex permittivity of Tobacco leaves has been measured over the 9.85 GHz single High frequency range using X - band microwave bench. To measure the dielectric parameter by using Sample holder for pulverized sample. We have designed and fabricated the sample holder at Microwave Research Laboratory, NES, Science College, Nanded. The experimental and calculated values for dielectric constant ( ) and dielectric loss ( ) are found to be same at relative packing fractions δr = 1. The above fact indicates that there is a fair agreement between calculated values of dielectric parameters and measured values of solid bulk. The co-relation formulae of Bottcher can be used to provide accurate estimates of ( ) and ( ) of powder materials at known bulk densities. The values of ( p) obtained suggest that the dielectric loss factor ( p) increases with the increase of bulk density of the material. The increase in conductivity with increase of packing fraction suggests that, at higher compaction the particles are more packed, and no micro-cracks developed in the samples. As packing fractions (δr) and temperature increases the moisture content of sample decreases linearly. The variations of ( p), ( p), tanδ, and σp with relative packing fraction (δr), and temperature clearly indicates that, effect of density and temperature on the dielectric parameters. The result shows that large cohesion in the particles of Tobacco leaves powder under investigations.

Electromechanical properties of uniaxial polar ionic plastic crystal [(C2H5)4N][FeBrCl3

Abstract Ferroelectric plastic crystals are an emerging class of materials that combine room temperature ferroelectricity and piezoelectricity with a high temperature plastic mesophase prior to melting. These materials offer possibilities for accessing different property parameter spaces from the state-of-the-art metal oxide and polymer ferroelectrics. Tetraethylammonium bromotrichloroferrite, [(C2H5)4N][FeBrCl3], has a unipolar wurtzite-like structure and thus may have potential for small but stable piezoelectric coefficients like the iso-symmetrical AlN. In this study, density functional theory was used to compute elastic compliance, piezoelectric coefficients, and dielectric constant values. Single crystals grown from aqueous solutions were evaluated via single crystal synchrotron x-ray diffraction, impedance spectroscopy and high and weak-field electromechanical characterization. Diffraction studies revealed that the anion tetrahedra orientated preferentially so that the Br− ion had a 30% alignment with the polarization vector. Electromechanical measurements found piezoelectric coefficients in the 5–9 pC N−1 and pm V−1 range. The piezoelectric coefficient (d 33) was most stable with 3.4% variation between 0.4 and 90 Hz and 0.5 and 3 V. Additional piezoelectric stability measurements were made as a function of DC bias field and temperature. Impedance measurements indicate contributions from either intrinsic effects unique to ionic plastic crystals, such as molecular rotation, or the extrinsic effect of electrode interfaces, both of which can play a role in the electromechanical response of the materials. The results show that [(C2H5)4N][FeBrCl3] has potential as a small signal piezoelectric that has a softer elastic moduli than AlN but a stiffer moduli than polyvinylidene fluoride, and thus occupies a unique parameter space.

Enhanced Dielectric Constant of PVDF-HFP/BFO Composite Films for Ferroelectric Applications

We have developed multiferroic Bismuth ferrite (BiFeO3, BFO) incorporated Poly (vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) polymer-ceramic composites through the solution casting method. The polymer-ceramic composites are fabricated by varying the composition of the BFO as a filler material ranging 5, 10, 15, 20, 25, 30, and 40 wt% into the PVDF-HFP polymer matrix. We have investigated the effect of BFO loading on the structural, morphological, spectroscopic, and dielectric properties by different characterization techniques. X-ray diffraction analysis indicates the presence of non-polar α- and polar β- phases of PVDF-HFP in the composites. Scanning electron microscope studies revealed the spherulite morphology and homogenous dispersion of BFO particles. The addition of BFO filler in PVDF-HFP matrix at various percentages has been studied to improve the polar β- phase of PVDF-HFP which may enhance ferroelectric properties. The dielectric studies at room temperature showed an increase in dielectric constant value from 9.5 (pure PVDF-HFP) to 21.08 (30% loaded BFO) at 100 Hz. It is also evident from the Fourier Transform- Infrared (FT-IR) spectra, that a maximum of 75.24% of β-fraction is observed for 30% loaded BFO composition. The enhanced properties of the fabricated materials suggest that they may be useful for polymer-ceramic capacitor applications. The results are discussed in detail.

4 Bromo—4’Chloro Benzylidene Aniline - as per suggestion it is named as 4B4CBA; Schiff based organic material has been synthesized and successfully grown by slow solvent evaporation technique. The orthorhombic crystal system of the grown crystal with space group Pccn is confirmed and cell parameters of the grown crystal of 4B4CBA is found by single crystal X-ray diffraction (XRD) analysis. The forming of the C-Cl and C-Br stretching vibrations at 719 cm−1 and 538 cm−1 in Fourier Transform Infra-Red (FTIR) study reveal the confirmation of 4B4CBA compound. The CHNSO analysis shows the presence of element in the 4B4CBA. The lower cutoff wavelength and wide optical absorption window of 4B4CBA exhibit the suitability of the present material for the projective opto-electronic applications. Nonlinear optical efficiency for different micro-crystalline of 4B4CBA is determined by second harmonic generation (SHG) experiment and is also compared with Potassium Dihydrogen Phosphate - KDP material. The electrical studies confirm that the 4B4CBA crystal possess low dielectric constant values at high frequency region. The experiment of photo-conductivity confirms the nature of the photo-conductivity of 4B4CBA crystal. The Scanning electron microscopy (SEM) analysis reveals the morphology of 4B4CBA crystal.

Optical and gamma ray shielding properties of lead magnesium zinc borate (PMZB) glasses

As the concentration of PbO in PMZB glasses is increased, the result is an elevated density and a reduced molar volume. As the percentage of PbO in the sample grows, the absorption peak in the optical spectrum has moved towards longer wavelength side. Creating non-bridging oxygens leads to a reduced gap in the band energy. When the content of Pb rises, so do the dielectric and optical dielectric constant values and the refractive index, suggesting an enhanced influence of non-bridging oxygens. The non-metallic character is confirmed by the metallization values, which vary from 0.382 to 0.362. Molar refractivity decreases with PbO content. This study conducted an evaluation of the radiation shielding characteristics in the 0.122–1.46 MeV range. The linear attenuation coefficient varied between 11.073 and 15.161 cm−1 at 0.122 MeV. The PMZBX glasses have lesser absorbing capabilities for high energy photons because of their greater penetration abilities. Thus, the PMZB4 glass, which has the greatest PbO content, shows the most promise out of the tested glasses.

Dielectric and Electrical Behavior of Apraseodymium Based Tungsten Bronze Ceramics

AbstractThe ceramic oxide Na2Ba2Pr2W2Ti4Nb4O30 (NBPWTN) is prepared by a mechanical mixed oxide route. The compound formation and the phase are concluded from the x‐ray diffraction pattern taken at room temperature (XRD). The uniform distribution of grains of various sizes with negligible voids is studied from scanning electron micrograph of the sample pellet. The presence of dielectric dispersion and ferroelectric phase in the material is observed from the temperature‐dependent dielectric parameters at selected frequencies. The existence of ferroelectricity in the material is further confirmed by the room temperature hysteresis loop. Impedance spectroscopic studies informed about the correlation between the microstructure and electrical behavior. The frequency variation of AC conductivity refers to Jonscher's law. The temperature variation of frequency exponent term n indicates OLPT (overlapping large polaron‐tunneling) model of the conduction mechanism in the sample. NBPWTN is a strong candidate for applications involving thermistor‐related devices because of the temperature dependency of resistance. The value of temperature sensitivity coefficient β in our investigation is achieved between 2000 and 11 000 K, confirming that the material has a high‐temperature stability property and is ideal for high‐temperature electronics applications. The high room temperature dielectric constant value of the ceramic (around 500) is useful for dielectric capacitor applications.

Structural, magnetic, impedance and electric modulus response and dielectric relaxation in Co-doped inverse spinel [formula omitted] nanoferrite

In this research work, we report synthesis, structural, electric and magnetic properties of Cu1−XCoXFe2O4(x = 0.05, 0.10, 0.15, 0.20) nanoferrite. All the samples are synthesized using sol-gel auto-combustion method. X-ray diffraction patterns validate the formation of single phase tetragonal structure at room temperature for all the samples. Absence of secondary phases confirms the successful substitution of Cu2+ by Co2+ ions in CuFe2O4 matrix. Dielectric analysis reveals that all the materials exhibit remarkable single dielectric relaxation. The dielectric relaxation peaks are observed between 150–225 °C. In addition, Co-doped CuFe2O4 exhibit marked enhancement of dielectric constant value for potential technological applications. Further, the correlated barrier hopping (CBH) model well explains the conduction phenomena in all the samples. Activation energy values are analyzed by applying the Arrhenius equation. Impedance analysis indicates that both grain and grain boundary effects contributed the electrical response in the ferrites which is confirmed from the plot of Z″ vs. Z′. The bulk and grain boundary response are further determined by modeling the impedance data with an equivalent circuit. Modulus study confirms the existence of non-Debye type of relaxation in the synthesized ferrites. Magnetic study shows the improved value of magnetic parameters such as saturation magnetization (Ms), remanent magnetization (Mr) and coercive field (Hc).

Plasma-Driven Tuning of Dielectric Permittivity in Graphene.

Materials with tunable negative electromagnetic performance, i.e., where dielectric permittivity becomes negative, have long been pursued in materials research due to their peculiar electromagnetic (EM) characteristics. Here, this promising feature is reported in materials on the case of plasma-synthesized nitrogen-doped graphene sheets with tunable permittivity over a wide (1-40GHz) frequency range. Selectively incorporated nitrogen atoms in a graphene scaffold tailor the electronic structure in a way that provides an ultra-low energy (0.5-2eV) 2D surface plasmon excitation, leading to subunitary and negative dielectric constant values in the Ka-band, from 30 up to 40GHz. By allowing the tailoring of structures at atomic scale, this novel plasma-based approach creates a new paradigm for designing 2D nanomaterials like nanocarbons with controllable and tunable permittivity, opening a path to the next generation of 2D metamaterials.

Theoretical insights into the electronic and optical properties of lithium-based perovskite for solar cell applications

This study explores the influence of central metals and halide anions on the structural, electronic, and optical properties of LiBX3 perovskites (B = Ge, Sn, Pb, X = F, Cl, Br, I) in both unit cell and supercell configurations, aiming for potential applications in photovoltaic devices. Density functional theory calculations reveal that increasing the atomic radius of halogens and central metals directly affects the lattice parameters. Our research indicates that Ge and Sn-based perovskites (except for unit cell LiSnF3) exhibit semiconductor properties with direct band gap energies, while Pb-based perovskites in the unit cell configuration display an indirect band gap. Key factors contributing to the reduction of the band gap energy in most materials include the expansion of the atomic radius of halogens and the examination of perovskites in their supercell state, such that perovskites like LiGeI3, LiSnI3, and LiPbI3 represent a band gap value of 0.001 eV in their supercell configuration. Furthermore, the light absorption characteristics of these perovskites demonstrate a high absorption coefficient ranging from 105 to 106. Among the studied compounds, I-based perovskites exhibit the highest static dielectric constant, surpassing other perovskite variants, with for example, unit cell and supercell of LiSnI3 having static dielectric constant values of 38 and 70, respectively. Additionally, the investigation of perovskites in their supercell form suggests that the number of atoms in the network does not significantly impact their optical properties. In conclusion, based on various analyses, I-based perovskites are proposed as ideal candidates for application in Photovoltaic Solar Cells (PSCs).

This research paper presents a soil brick moisture measurement by capacitive measurement with radio frequency of 50 MHz and the soil brick as the dielectric material sandwiched between the conductive plates of the capacitor. The moisture content of the soil brick was considered from the capacitance storage capacity of the capacitor. The proposed measurement consisted of a voltage-controlled oscillator, capacitance measurement circuit, radio frequency amplifier, radio frequency detector, and microcontroller unit. After that, a circuit was built and assembled to the radio frequency soil moisture meter of soil bricks for evaluate the soil brick with width of 20 cm, length of 40 cm and the thickness of 20 cm. There are four types of soil brick with moisture of 10% to 30% and 10 times of iterations. From measured results, it was found that the dielectric constant and capacitive value are directed variation with moisture content of soil bricks. Therefore, the moisture content of soil bricks can be found by capacitive measurement. From the measured results, it accurate when comparing the standard measurement with an error of 4–16%.

Antimony-doped cerium ferrite: a robust photocatalyst for the mitigation of diclofenac potassium, an emerging contaminant

The present work reports an improvement in the photocatalytic performance of cerium ferrite (CeFeO3) via doping of antimony (Sb) towards the photodegradation of toxic pharmaceutical pollutant i.e. diclofenac potassium. The variable concentrations of Ce1-xSbxFeO3 (x = 0.00, 0.01, 0.03, 0.05, 0.06, 0.07, 0.09) were prepared using facile co-precipitation route and subsequently characterized for their optical, structural, morphological, and dielectric properties using various analytical techniques. It was established that an increase in Sb concentration as dopant (up to x = 0.07) reduced the optical band gap from 2.74 eV to 2.42 eV making it suitable candidate for photodegradation. The X-ray diffraction (XRD) pattern revealed orthorhombic phase of synthesized materials with small crystallite sizes in the range of 15.28 to 2.42 nm. The high value of dielectric constant (3.5841 × 106) for Ce0.93Sb0.07FeO3 with small loss tan (3.1208) compared with the CeFeO3 indicated its ability as photocatalyst to effectively store charges to make them utilize for photocatalytic activity. The degradation efficiency of Ce0.93Sb0.07FeO3 reached 86.7% in 120 min of light irradiation under optimized conditions (pH = 4, catalyst dosage = 15 mg, primary drug concentration = 5 mg/L). Ce0.93Sb0.07FeO3 was also found to be stable over its multiple catalytic runs as only 6.5% decline in degradation efficiency was observed in recyclability test. The remarkable performance of antimony doped cerium ferrite against the removal of persistent pharmaceutical pollutant indicated its strong potential to be used in wastewater treatment in future works.

Card-bisphenol based bio-silica reinforced poly(urethane-co-benzoxazine) foam for an electrical insulation

Agricultural waste by-products such as cashew nut shell liquid and rice husk ash were utilized for the syntheses of card-bisphenol (C) and precipitated bio-silica (S), respectively. A hydroxyl terminated card-bisphenol based benzoxazine resin (CHB) was synthesized and then converted it into soft-foam namely benzoxazine-co-urethane pre-polymer (CHB-UF) by polymerizing with hexamethylene diisocyanate (HMDI) in the absence of any catalysts or foaming agents. Subsequent thermal ring opening polymerization of CHB-UF at 200 °C provides poly(benzoxazine-co-urethane) hard-foam (PCHB-UF) with little shrinkage. Similarly, different weight ratios of precipitated bio-silica (0–15 wt%) reinforced bio-based PCHB-UF hard-foam composites (PCHB-UFS) were prepared to utilize them for high-k dielectrics and hydrophobic applications. The foam microstructure was ascertained through the field emission scanning electron microscopy (FE-SEM). The reinforcement of bio-silica into the CHB-UF foam increases the value of dielectric constant according to the increase in weight percentage concentration, which might be due to the reduction in volume of voids. The neat PCHB-UF possesses the value of dielectric constant of 7.04 with lower value of dielectric loss of 0.01. Similarly, the values of dielectric constant and dielectric loss of 15 wt% bio-silica reinforced composites (PCHB-UFS15) are 10.1 and 0.08 respectively. The PCHB-UFS15 has shown hydrophobic nature with the value of water contact angle of 135°. Data obtained from different studies suggest that the bio-foam composites obtained from sustainable sources can be considered as an efficient dielectric materials used for electronics insulation.

Determination of optimum limestone filler content in asphalt mastic by dielectric spectroscopy

The rheological and dielectric characteristics of asphalt mastics with different ratios of limestone filler were analyzed and compared with each other for road pavement applications. The dielectric properties of asphalt mastics are studied as a function of frequency (0,1–106 Hz) at different temperatures ((-)40°C−40°C). The glass transition temperature and the relaxation behaviour were determined by Vogel–Fulcher-Tamman and Cole–Cole equations, respectively. The free volume fraction was calculated by the Dolittle equation. The filler ratio dependence of the dielectric properties was attributed to the variation of the void fraction. This result was related to the glass transition temperature and ductility. The sample with 6 wt% limestone filler showed the highest dielectric constant value among all samples for all temperatures due to the excellent adhesion between binder and filler. Consequently, it was determined to be the optimum value to design hot mix asphalt for use in territories with high-temperature differences.

Sm3+ doping-adjusted mechanical, dielectric, and radiation shielding properties of cobalt copper nanoferrites

The scarcity of research on the shielding properties of spinel ferrites underscores the necessity for more rigorous investigations. Consequently, this study introduces a facile synthesis method for Co, Cu, and Sm spinel nanoferrites (referred to as CCS nanoferrites) using the citrate combustion technique. The investigation focuses on their mechanical, dielectric, and gamma-ray shielding parameters. Gamma-ray shielding features are obtained theoretically via the Phy-X database. The particle size, nature, and distribution of the present CCS nanoferrites were analyzed using HR-TEM microscopy. HR-TEM results reveal both the spherical shapes and the aggregation of nanoparticles. These observations can be attributed to the interplay of high surface energy and magnetic interactions among the components of the CCS nanoferrites. The Co0.5Cu0.5Sm0.15Fe1.85O4 nanoferrite exhibits an optimal dielectric constant value of 4587, with an enhanced ratio of 1618% compared to the pristine CCS0 sample. Additionally, it demonstrates an optimal conductivity of 38.59 μ (Ω·m)−1, with an enhanced ratio of 1105%. Furthermore, the loss is reduced to 2.65, showing an improvement ratio of 54% compared to the pristine nanoferrite at room temperature and 50 Hz. Moreover, the longitudinal modulus, shear modulus, Young's modulus, and bulk modulus of the nanoferrite Co0.5Cu0.5Sm0.15Fe1.85O4 were increased from 1.79 to 4.96 GPa, 0.32–0.93 GPa, 0.88–2.56 GPa, and 1.37–3.73 GPa, respectively, when compared to the pristine sample. The comparative study of half-value layers at 0.662 MeV revealed that CCS nanoferrites exhibit smaller half-value layers than common radiation shielding materials. Additionally, the study highlighted the enhanced radiation shielding performance of the nanoferrites. Concerning the dielectric, mechanical, and ionizing radiation shielding properties of the CCS spinel nanoferrites, the CCS5 (with the highest Sm content) has the optimum ionizing radiation shielding ability with the highest dielectric and mechanical parameters compared to the other samples. The implications of these findings extend to potential applications in biomedicine, radiation protection, and the optimization of electronic devices operating in radiation fields.
