ABSTRACT A new four-parameter generalized van der Waals equation of state is proposed. The criteria for the applicability of the proposed equation of state in describing the thermodynamic properties of substances have been formulated. The generalized van der Waals equation of state is found to be applicable to vanadium, niobium and tantalum. To validate the generalized van der Waals equation of state, the spinodal, ideal tensile strength, thermodynamic limit of superheat and binodal of vanadium, niobium and tantalum have been determined. The obtained results agree with that of Filippov correlation and other equations of state. Using the obtained spinodal, the binodal of vanadium, niobium and tantalum has been determined.

ABSTRACT The standard solid state reaction method was followed to synthesize the polycrystalline xBa0.95Sr0.05TiO3-(1–x)BiFe0.9Sm0.1O3 [xBST-(1–x)BFSmO, x = 0–0.35] ceramics. The XRD pattern revealed a structural transition of the prepared ceramics from rhombohedral to cubic symmetry. The mean grain size was estimated in the micrometer range, with values ranging from 0.40 to 1.95 μm. The maximum real part of the complex initial permeability of 28.26 was noticed for x = 0.30 multiferroic ceramics. The highest remanent magnetization determined for the x = 0.30 sample was 3.4 10−2 emu/g. For the sample with x = 0.35 the maximum recorded dielectric constant was found to be 677 at 103 Hz. A small value of dielectric loss (<5%) was observed. The compound exhibited significant remanent polarization and a reduction in the leakage current. In addition, the investigated materials comprise large magnetoelectric coefficients and the optimum magnetoelectric coefficient of 0.662 mV.cm−1.Oe−1was obtained for the x = 0.30 composition.

ABSTRACT Polycrystalline chalcopyrite CuGaS2 thin films were prepared using a spray pyrolysis route has been considered a potential material for the solar cell absorber layer. Scanning Electron Microscopy (SEM) and Atomic Force Microscopy (AFM) studied the impact of substrate temperature in the range of 200–300˚C on surface profile and roughness. Powder X-ray diffraction disclosed that the films were polycrystalline at all examined substrate temperatures, with crystallite size increasing with increased substrate temperature. The UV-Vis displays the cut-off wavelength in 550–880 nm for varied substrate temperatures of CuGaS2 thin films, and the observed band gap is 2.75 eV–1.89 eV. The electrical attributes showed the enhancement in mobility (4.632 cm2 V−1 s−1) for varied substrate temperatures of CuGaS2 thin films. The 300˚C temperature sprayed CuGaS2 polycrystalline films are a decent candidate to be apposite as an absorber layer in thin film photovoltaic solar cells.

ABSTRACT The effect of ageing process at 1073.15 K on the athermal phase transformation in different nanograins (4.5, 6 and 9 nm) of Nickel–Titanium shape memory alloy is studied using molecular dynamics simulations. The martensitic transformation start temperature and transformed martensite volume decrease with decreasing grain size. The two-stage phase transformation with intermediate phase formation is observed only in the smallest grain (4.5 nm) where a single martensite variant is formed. On the contrary, larger grains show a self-accommodated twinned martensite variants with one-stage transformation from austenite to martensite. The ageing process hardly influences the morphology of the martensite phase, however, it rises the martensite start temperature and reduces the austenite start temperature. The nano grain size models demonstrate the constrained transformation due to the transformation barrier and the accumulation of internal stress, while the ageing process shows the tendency for stress relaxation.

ABSTRACT The results of differential thermal analysis of the Se70Te20Cd10 glass under non-isothermal settings are presented and analyzed. The heating rate affects the temperature of the glass transition (Tg ), the onset temperature of crystallization (Tc ) and the peak temperature of crystallization (Tp ). The glass transition activation energy (Eg ), the crystallization activation energy (Ec ), the Hurby number (Hr ) and the order parameter (n) were all calculated. The results show that the rate of crystallization is connected to heat stability and glass-forming capabilities for the current composition. The results indicate two-dimensional development for the composition Se70Te20Cd10 in accordance with the Avrami exponent (n).

ABSTRACT Dy substituted Ni ferrite nanoparticles with composition NiFe1.95Dy0.05O4 were synthesized by using the citric acid sol–gel auto combustion method. The samples were sintered at temperatures of 400°C, 700°C, and 900°C. The X-ray diffraction measurements clearly showed the formation of a cubic spinel structure along with a small orthoferrite phase for all the sintered samples. The crystallite size increases from 17.79 to 39.36 nm while the grain size increases from 50.70 nm to 83.05 nm. The lattice parameter and lattice volume decrease with increasing sintering temperature was observed. The Spinel ferrite structure of prepared samples has been confirmed from FTIR spectra. With increasing sintering temperature saturation magnetization increases from 25.80 emu/gm to 49.48 emu/gm while the coercivity value decreases from 207.95 Oe to 165.43 Oe. Increasing saturation magnetization and decreasing coercivity values with increasing sintering temperature make the synthesized nanoparticles suitable for high-density data storage devices.

ABSTRACT Herein, we report the detection and removal/degradation of metal ions and dye species using nanotechnology-based approach. A Schiff base (Sb) ligand has been prepared by a solvent-less method; post which, the ligand is used for functionalizing zinc sulphide nanoparticles (ZnS NPs) in the aqueous medium. The Sb–ZnS NPs proved to be a dual probe, viz., for the detection of Pb2+, Hg2+ and Fe3+ ions, and as a photocatalyst for the degradation of methylene blue (MB) dye. The experiments using the Sb–ZnS NP photocatalyst under daylight illumination revealed higher efficiency with 96% degradation of MB than that in the dark with only 66% degradation of the dye. Further, the degradation of the dye followed first-order rate kinetics with a higher rate constant for light-illuminated sample (16.3 × 10−4 min−1) than the one kept at dark (6.85 × 10−4 min−1). UV–Vis, PL, FT-IR, TEM and powder XRD analyses have been routinely used for the present investigation.

ABSTRACT MgF2 is a compound that is transparent to the full spectrum from UV to IR and is a good candidate for UV applications. Structural, optical, electronic and elastic properties of MgF2 compounds in the three phases in which our materials may crystallize have been studied using the linearized full potential self-consistent plane wave (FLAPW) method with Wu-Cohen generalized gradient approximation (WC-GGA) and modified Becke–Johnson potentials. The most remarkable is the similarity between the properties of the three phases at all levels (gaps, optical constants). A comparison of our outcomes with the literature indicates great agreement.

ABSTRACT The ceramic composite electronic material of (Sn0.8Ti0.2)O2 has been synthesized through a cost-effective solid-state ceramic approach. The crystallographic tetragonal structure from the XRD spectrum, hydrophilic porous structure from SEM micrograph, dielectric, conductivity, and electrical modulus in addition to impedance spectroscopy over an extensive range of temperature and frequency have been elucidated. Hydrophilicity, superior dielectric response with significantly low dielectric loss, and enhanced capacitive behaviour draw the major attraction of this ceramic-based material system. The temperature-dependent conductivity spectrum evinces Arrhenius’s behaviour. The grain and grain boundary effects in the synthesized sample has been displayed through the Nyquist spectrum. The non-Debye type of relaxation mechanism has been established through an electric modulus study. The extensive study sketched out this composite as a potential capacitive electronic component for humidity sensor device applications. The investigated electrical parameters associated with the ceramic composite may enlighten the development of functional electronic devices.
