PVDF-co HFP blended PMMA complexed with Mg(CF3SO3)2 polymer electrolytes were synthesized using the solution casting process, zirconium nanofiller of 20 nm has been distributed with various concentrations. Utilising electronic Impedance Spectroscopy from 1Hz to 10MHz at various temperatures, the sample's electrical properties are investigated. The dielectric permittivity values of real (ε'), imaginary (ε"), electric modulus (M' and M"), and relaxation time are used to analyse the sample's dielectric behaviour. The thermal behaviour of composite polymer electrolytes Disseminated with Zirconium nanofiller are changed tremendously. The ionic conduction of nano composite polymer electrolyte films has been improved by one order of magnitude by the addition of nano filler, and the extreme ionic conductivity (0.3434 x 10−3 Scm−1) is perceived for 8 wt % of ZrO2 dispersed in PVDF-co-HFP, PMMA & Mg(CF3SO3)2 polymer electrolyte system. The growth in conductivity is ascribed to an increase in disconnection of ions and conception of large number of conducting paths for ion mobility by the addition of nano sized ZrO2.

The goal of the Multi-Purpose Detector (MPD) experiment at NICA collider is to explore the QCD phase diagram of strongly interacting matter produced in nucleus-nucleus collisions at S N N = 4 − 11 Gev. The performance of MPD detector for elliptic flow measurements of charged hadrons is studied with Monte-Carlo simulations using collisions of Au+Au ions employing UrQMD, SMASH, and AMPT heavy-ion event generators. Different methods for flow measurements: event plane and direct cumulants are used to investigate the contribution of non-flow correlations and flow fluctuations. [ABSTRACT FROM AUTHOR]

RAON, which is an acronym of Rare isotope Accelerator complex for ON-line experiment, is being constructed in Korea. Among various experimental setups at RAON, the LAMPS (Large Acceptance Multi-Purpose Spectrometer) system is dedicated to studying the equation of state (EoS) and symmetry energy of the compressed nuclear matter. Several detector components for LAMPS, including the Time Projection Chamber (TPC) and the neutron detector array, have been developed, constructed and tested. The characteristics of TPC fullfill the requirements of LAMPS, as the drift velocity is larger than 6 cm/μs and the position resolution is smaller than 250 μm. The time and position resolutions of the prototype neutron detectors are measured to be 309 ps and 4.8 cm, respectively, which are superior to other existing neutron detectors with similar configuration. The current status of the detector developments for LAMPS is summarized with some perspectives. [ABSTRACT FROM AUTHOR]

The present study reveals the high pressure phase transition and associated volume collapse of SmAs which crystallize in NaCl (B1) structure. We have calculated the phase transition pressure, volume collapse and second order elastic constants of SmAs. In order to achieve this goal, we have formulated a three-body interaction potential model (TBIPM), which consists of the long-range Coulomb and three-body interactions and Born-Mayer overlap repulsion operative up to next nearest neighbor ions. This compound undergoes transition from NaCl structure to body-centered tetragonal (BCT) structure (distorted CsCl-type P4/mmm). The values of phase transition pressure and associated volume collapse estimated by us are found to be well suited with experimental values. Thus, our TBIPM is in good agreement with available measured data of SmAs. [ABSTRACT FROM AUTHOR]

In the present paper, we have evaluated the phase transformation and elastic properties of MnO at high pressure by formulating effective interionic interaction potential. The elastic constants, including the long-range Coulomb and van der Waals (vdW) interactions and the short-range repulsive interaction of up to second-neighbor ions within the Hafemeister and Flygare approach, are derived. Assuming that both the ions are polarizable, we employed the Slater-Kirkwood variational method to estimate the vdW coefficients .From the present study, we predict a structural phase transition from NaCl structure (B1) to CsCl structure (B2). The estimated value of the phase transition pressure (Pt) and the magnitude of the discontinuity in volume at the transition pressure are consistent as compared to the other theoretical data. The variations of elastic constants with pressure follow a systematic trend identical to that observed in others compounds of NaCl type structure family. [ABSTRACT FROM AUTHOR]

Due to ion mobility properties, Zn powder had been chosen as anode part in this Zn-air battery study. So, binder is needed to produce the compact form of Zn anode since the powder form will segregate and move freely in the electrolyte. The presence of the binder should be importantly considered if the binder will affect the electrochemical performance of battery. The conductivity test was conducted on binder to verify the ability of natural binder as ionic carrier in porous Zn anode by applying different concentration of KOH. Then, second test is to find out the electrochemical stability window of binder in the different concentration of KOH. The conductivity value increasing with increasing of KOH concentration with the recorded highest value owned by Bacto-agar in 0.2 M KOH, 1.63 x 104 Scm-1. However, the highest window stability value was possessed by commercial agar with the value of 2.219 V in 0.2 M KOH. [ABSTRACT FROM AUTHOR]

Here we are exploring the widespread features or the characteristics of the microscopic transport modeling and also the speculations made for the approach to fit it to the dynamics of high energy heavy ion collisions, when we see its expansion in space-time dimensions. The explanation of initial stages of the hot and high dense region, the hydrodynamics is instigated and further moderate stages of reaction are complemented to microscopic transport.

Kinetic Alfven wave (KAW) generation due to variation of loss-cone index J and density of multi-ions (H+, He+ and O+) in the plasma sheet boundary layer region (PSBL) is investigated. Kinetic approach is used to derive dispersion relation of wave using Vlasov equation. Variation of frequency with respect to wide range of k⊥ρi (where k⊥ is wave vector across the magnetic field, ρi is gyroradius of ions and i denotes H+, He+ and O+ ions) is analyzed. It is found that each ion gyroradius and number density shows different effect on wave generation with varying width of loss-cone. KAW is generated with multi-ions (H+, He+ and O+) over wide regime for J=1 and shows dissimilar effect for J=2. Frequency is reduced with increasing density of gyrating He+ and O+ ions. Wave frequency is obtained within the reported range which strongly supports generation of kinetic Alfven waves. A sudden drop of frequency is also observed for H+ and He+ ion which may be due to heavy penetration of these ions through the loss-cone. The parameters of PSBL region are used for numerical calculation. The application of these results are in understanding the effect of gyrating multi-ions in transfer of energy and Poynting flux losses from PSBL region towards ionosphere and also describing the generation of aurora.

We have performed the phase transformation and elastic properties of BeO at high pressure by formulating effective interionic interaction potential. The elastic constants, including the long-range Coulomb and van der Waals (vdW) interactions and the short-range repulsive interaction of up to second-neighbor ions within the Hafemeister and Flygare approach, are derived. Assuming that both the ions are polarizable, we employed the Slater-Kirkwood variational method to estimate the vdW coefficients, a structural phase transition (Pt) from ZnS structure (B3) to NaCl structure (B1) at 108 GPa has been predicted for BeO. The estimated value of the phase transition pressure (Pt) and the magnitude of the discontinuity in volume at the transition pressure are consistent as compared to the theoretical data. The variations of elastic constants with pressure follow a systematic trend identical to that observed in others compounds of ZnS type structure family. [ABSTRACT FROM AUTHOR]

In this paper, the effect of ion-neutral collision type on the ion cloud formation around a dust particle immersed in plasma in the presence of an external electric field is considered. It is shown that elastic ion-neutral collisions in low-temperature low-density plasma lead to the persistence of directed velocity compared to the resonant charge exchange collisions, where ions lose almost their energy. Thus the ion drift velocity is larger for the case of elastic collisions than for resonant charge exchange collisions. With the increase of an external electric field strength, the charge of dust particle increases faster for the elastic case than for resonant case. The dipole moment of the ion cloud-dust particle system is also appeared to have higher values for the case of elastic collisions. [ABSTRACT FROM AUTHOR]

When deposited on a surface, electric charge usually accumulates near the tips of surface irregularities, from where it can be transferred to nearby objects due to ionization of ambient air. The amount of transferred charge, the rate of charge transfer, the size of the charged spot (e.g., on the surface of an insulator) and its tendency to spread will depend on properties of air during electric discharge, on the magnitude of charge accumulated at the tip of an object, on possibilities for replenishing that charge, on the time spent for charge transfer from the tip onto the insulating layer, on properties of the insulating layer, etc. Those properties are discussed in this work by comparing the results of measurements and theoretical analysis.

Water is an integral part of living organisms and it amounts to 80-90% of their weight. Water has many-sided significance on a cell. It acts as a solvent for mineral and for many organic materials, it is a medium for transportation of nutrients, were enzyme-catalysed metabolic reactions take place and chemical energy is transferred. Exposure to magnetic fields has changed water properties: polarized liquid structures are destroyed; changes occur in water, in ionic mobility of solutions and in intermolecular contacts, moistening and capillary properties of water (adhesion, cohesion) have been changed, as well as electrical conductivity, dielectric permittivity, magneto-optical characteristics and effect on biological objects. The article analyses effect of industrial frequency magnetic fields on moisturising properties of water and solution. Analysis of the obtained results showed that dilatation area on filter paper and height of water in a capillary glass tube of magnetised water and solution depended on strength of magnetic field (H) and on speed of water and solution movement (v) through magnetising apparatus.

We investigate the properties of the insulator surface or environment by charging insulator through the needle shape electrode and calculating and measuring kinetics of deposited charge. It can be determined the sheet resistance of isolator surface. Deposited ions can move and this changes charge density distribution. The tangential electric field strength component causes charge distribution on the insulator surface. This distribution is initial condition for the splitting charge calculation on the isolator surface. In this work we study only slow charge movement on isolator surface compare to the charge deposition rate from the needle onto the isolator surface. [ABSTRACT FROM AUTHOR]
