Article 4. Investigation Of Effective Permeability And Dielectric Aspect Of Dilute Magnetic Dielectrics By Optical Method

The objective of the fourth article of the issue is to investigate the magnetic nature of Dilute Magnetic Dielectrics (DMD) under variation of external magnetic field. The said variation is studied over developed nano sized Gadolinium Nickel Sulfide complex, Cobalt Sulfide, Nickel Sulfide and Titanium Sulfide as a DMD system. Here, the experiment records the variation of Brewster angle of incident polarized LASER beam from the surface of developed DMD specimen with applied out of plane external magnetic field. The relative permittivity and relative magnetic permeability were estimated by following the electromagnetic theory. The overall results obtained are found to be holding a good agreement between theory and experiment.

Article 5. Effect Of Sorbitol Addition To Polymer Solid Electrolytes Based On Chitosan

The fifth article reported by the Evi Yulianti et al from Centre For Science And Technology Of Advanced Materials – National Nuclear Energy Agency, Indonesia.

Here author emphasize about the Solid Polymer Electrolyte. Solid Polymer Electrolyte has great potential in replacing liquid electrolytes. The SPE has many advantages such as high thermal stability, good flexibility, and non-flammable. One of the polymers that can be used is chitosan biopolymer from shrimp skin extraction. In this study the synthesis of chitosan electrolyte film was prepared by casting method. Then qualitative and quantitative analysis was carried out by using X-ray diffraction, electrochemical impedance spectroscopy, and mechanical properties. Here, sorbitol addition also increases the tensile strength, elongation and Young modulus of film flexibility become 52.3%, and 158.3MPa and 19.8MPa, respectively.

Article 7. Complex Formation Behavior Of Copper-Tin Alloys At Its Molten State

The seventh article of the issue presents the details about the materials formation behavior. This study is published by N. Panthi et al. from Tribhuvan University, Nepal. Here, thermodynamic and structural properties of compound forming binary liquid copper tin alloy at 1400K have been well analyzed as a function of concentration by considering Cu3Sn complex by using Quasi lattice model. The study provides the information of moderately interacting as well as ordering nature on the entire range of concentration of the liquid alloy. Similarly, transport and surface properties (viscosity surface tension) of the liquid have also been studied under statistical models; Budai-Banko-Kaptay model and Butler's approach. The viscosities and surface tension of the alloys computed predicts noticeable negative derivation from ideal case and these increase with increase in copper atoms in the alloy.

Article 8. Thermoelectric Properties Of ZrxInxZn1-XO1-Δ Thin Films

The eighth article is published by the Prasoon Prasannan et al from Kannur University, India. In this work, variation of thermoelectric properties of Zr2O3-In2O3-ZnO film system is reported. The films are fabricated in a chemical composition satisfies the relation ZrxInxZn1-xO1-δ, (0.01≥ x ≥ 0.04), through spray pyrolysis technique. XRD analysis shows a switching of preferred crystal growth orientation from (002) to (100) and (101) planes as x increases. Here, maximum Seebeck coefficient of -159 µV/K was obtained for x=0.01 at 400K. The decrease in the Seebeck coefficient for higher x values is explained with simplified broadband model. At elevated temperature power factor increased considerably up to 2.33 X 10-4 Wm-1K-2 for x=0.03 which was attributed to decrease in sheet resistance at high temperature.
