Abstract: The ac conductivity σ and dielectric properties (dielectric constant ', dielectric loss '' and loss tangent tan δ) were measured as a function of frequency between 100 Hz and 20 MHz for the mixed ferrites ZnxMn1-xFe2O4 (where x = 0.2 to 0.8), synthesized by solid-state route. The ac conductivity σ below 1 MHz seems to be nearly frequency independent for all compositions; and above these frequency ranges, σ sharply increases until it reaches a maximum value. The relaxation time (τ) was found to be in the range 0.3x10-5 – 1.5x10-5sec from the hopping frequency. The dielectric constant for these ferrites is approximately inversely proportional to the square root of the resistivity. The electrical conduction mechanism was explained in terms of the electron hopping model. The formation of spinel structure and crystalline size was confirmed using X-ray diffraction (XRD) technique. Morphology of the samples was studied using Scanning Electron Microscopy (SEM).
Keywords: Solid-state route; spinel ferrite; dielectric properties; ac conductivity

Abstract: Various methods have been developed in the manufacture of Poly (vinylidene fluoride) (PVDF) thin films such as coating, spreading, evaporation and calendaring. The method of making this film certainly has many advantages and disadvantages as in the case of operational processes and also the cost of the required treatment. In this paper, an alternative method to preparation of PVDF thin films has been done through the development calendaring method by using roll hot press. The advantages of roll hot press are simple in terms of operation and relative low cost. PVDF thin film has been produced for several temperatures of roll hot press with several different thicknesses. The PVDF thin films are characterized using X-Ray Diffraction and IR spectra. In addition to determine the surface resistivity are caried out using I-V meter. We found that an increase in β fraction of PVDF thin films with increasing temperature at fixed film thickness, while the surface resistivity of PVDF film are decreased. This shown that the piezoelectric property of PVDF films has been improved.
Keywords: β fraction, piezoelectric, PVDF film, Roll hot press, Surface resistivity

Abstract: CuAlS2 thin films of the same thickness are deposited on suitably cleaned coning 7059 glass substrate by two stage vacuum thermal evaporation technique at room temperature and sulfurised at different temperatures. The structural properties studied by means of XRD revealed that the films are of crystalline in nature having tetragonal structure. For all the films the preferential orientation is [112]. The other orientations like [220], [312] and [400] were also observed in the films depending upon the sulfurisation temperatures. The values of lattice constants, grain size, micro strain and dislocation density of the films are calculated and the values agree strongly with ICDD data. Visual inspection of (SEM) micrographs of the films showed that crystallite size increase with increase in sulfurisation temperature.

Title	:	Entangled Photon Encoding Using Trapping of Picoseconds Soliton pulse
Country	:	Malaysia
Authors	:	I. S. Amiri, D. Gifany, J. Ali
	:	10.9790/4861-0312531

Abstract: The microring resonator (MRR) system can be used to trap optical solitons. These types of pulses are used to generate entangled photon required for quantum keys. The required information can be provided via the quantum keys. We simulate localized spatial and temporal soliton pulses to form an optical communication used in wireless systems. The input soliton pulses with peak power of 500 and 550 mW are used to generate a spectrum of chaotic signals within the nonlinear medium, where the nonlinear refractive index is selected to n2=2.2 x 10-17m2/W. The ultra-short soliton pulse can be trapped within the 3.52 GHz frequency, where the temporal soliton pulse with FWHM of 25 ps could be simulated and used to generate entangled photon pair. The generated entangled photons are input into a wireless router system which is used to transfer them within a network communication system. The router system is used to receive the information and convert it to analog signals at the end of the transmission link, thus data can be sent to the users via a secured optical communication system using MRRs

Abstract: A system of microring resonators (MRRs) is presented to generation entangled photon. Different time slot for continuous variable quantum key distribution (CVQKD) use is applicable in optical wireless link. Chaotic behavior of a soliton pulse within the device can be presented respect to the Kerr nonlinear type of light in the MRR devices. Continuous spatial and temporal signals are generated spreading over the spectrum. The CVQKD is formed using the localized spatial soliton pulse. Here localized temporal soliton with FWHM and FSR of 0.2 ps and 0.58 ns is obtained respectively. The spatial soliton pulse has a FWHM of 80 pm. Transmission of soliton pulse with FWHM of 1.5 ps is simulated along the long distance fiber optics where the polarized photons are formed incorporating with the polarization control unit into the MRRs, which allows different time slot entangled photons to be randomly formed.

Title	:	A Rapid and Simple Spectrophotometric Determination of Traces of Chromium (VI) in Waste Water Samples and in Soil samples by using 2-Hydroxy, 3-Methoxy Benzaldehyde Thiosemicarbazone (HMBATSC)

Abstract: A rapid and simple Spectrophotmetric method has been developed for the determination of microgram amount of Chromium (VI) in aqueous dimethyl formamide (DMF). Chromium (VI) forms a yellowish green coloured M:L complex with 2-hydroxy-3-methoxy benzaldehyde thiosemicarbazone in the acidic buffer medium (pH=6.0) at room temperature. The complex shows maximum absorption at 385nm. Beer's law is obeyed in the range 0.260 to 2.60  gmL-1. The sensitivity of the proposed method has been derived from its molar absorptivity value (1.202X103 lit.mol-1 cm-1), detection limit (0.014 g mL-1) and determination limit (0.041 g mL-1), correlation coefficient (0.9999) and relative standard deviation (0.32%) confirm the best suitability of the proposed method for the determination of chromium (VI). The effect of foreign ions on the determination was studied. A second order derivative spectrophotometric method for the determination of chromium (VI) has also been proposed. This method was applied for the determination of chromium (VI) concentration in samples of circulating industrial waste water, soil samples and in standard steel samples.

Title	:	Geoelectric Investigation Of Deghele Community In Warri South West L.G.A, Delta State, Nigeria
Country	:	Nigeria

Abstract : A geoelectric investigation has been conducted at Deghele Community, Warri South West L.G.A, Delta State, Nigeria. The Vertical Electrical Sounding (VES) method was adopted with maximum current electrode separation (AB) of 600m. The interpretation revealed four to six geoelectric layers which include Topsoil, Silty sand, Clay and Sand. The topsoil has thickness varying from about 1.43 to 3.8m while its resistivity values vary from 2.23 to 131 m. The second and third geoelectric layers are composed of Silty sand/sand. This layer which is saline has resistivity values ranging from 2.23 to 78m and thickness varying from 7 to 20 m. The low resistivity values may be as a result of tides propagating saline sea water inland through the interconnecting creeks. The fourth geoelectric layer is composed of sand with resistivity values varying from 1121 to 2796 m. This layer forms the aquifer unit and has a maximum thickness of about 170m and at a depth of about 180m. The sixth layer terminated in a clay formation with resistivity values of about 65 m. This study has provided an insight to the subsurface disposition of the aquifer systems and delineated areas for groundwater development programme in Deghele community.

Abstract: The nonlinear behavior of light such as chaos traveling in an optical fiber ring resonator as a single ring resonator is presented. This phenomenon can be used to generate secret codes or arbitrary digital codes of "0" and "1" applicable in the communication system such as time division multiple access (TDMA) system. Such a system can be used to secure the information signals therefore, the ability of chaotic carriers to synchronize in a communication system is performed. The used optical material is InGaAsP/InP regarding to suitable parameters of the system. The nonlinear refractive index is fixed to n2=3.8 × 10−20 m2/W. The input power is selected at 1 W, where the coupling coefficient of the system varies as 0   0.1. As a result, train of logic codes could be generated and transmitted via a fiber communication link using the chaotic signals. To optimize the microring systems, Lower input power is recommended in many applications in optical optical communication systems
