Experimental ultrasonic velocities of binary liquid mixture of acetone and carbon tetra chloride at temperatures 286.15 K, 289.15 K and 293.15 have been evaluatedat 2 MHz as a function of molar concentrations. The experimental values were compared with various theories for analysis of ultrasonic velocity in binary liquid mixtures such as Nomoto theory (NOM), ideal mixing relation (IMR) of Van Dael andVangeel, Impedance Relation (IDR), Rao’s Specific Velocity Method (Rao) and Junjie’s relations (JR). Chi-square test and average percentage error were applied to investigate the relative applicability of these theories to the present systems. The variation of thermo acoustical parameters of the systems with the mole fraction has been discussed in term of molecular interactions.

The optical signal processing is the future of communication network. High speed all-optical packet routing is one of the essential applications of all-optical networks which is only possible with the development of all-optical logic technology. The development of optical logic elements and circuits are the steps in the growth of this technology and higher speed up to Tbit/sec can be achieved. The optical carrier frequency range 1013 to 1016 Hz provides enormous potential bandwidth with superior information carrying capacity over a long transmission distance. The need of higher capacity is continuing to encourage research in wavelength division multiplexing (WDM) and optical time division multiplexing (OTDM) based transmission systems, which need optical demultiplexing and wavelength conversion technology. Therefore, for high-speed optical networks, it is required to develop the all-optical gates to avoid power consumption in opto-electronics conversion. All optical logic gates perform computing operations, storage and transmission of data using light also known as optical computing. Optical technology promises massive upgrades in the efficiency and speed of computers, aswell as significant shrinkage in their size and cost. The non-linear optical device to be used i.e. Semiconductor Optical Amplifier (SOA) has proved to be the promising for all optical functions like wavelength conversion, logic functions, signal representation in all optical domain. Its compact size, high gain, fast response, strong refractive index variation, easy to manufacture and integration, and power efficiency makes it most optimum device for optical signal processing. In this paper, the application of SOA in optical processing is thoroughly reviewed and orient towards the latest application in neural networks.

In the present study, we have investigated the motion of cylindrical imploding shock in a real dusty gas having uniform initial density distribution by using (CCW) Chester2 -Chisnell3 -Whitham (1958) method. It is considered that the real dusty gas is the mixture of real gas and a large number of small spherical solid particles of uniform size. Initial volume fraction of the solid particles is also assumed constant in this particular study. The particles do not interact with each other therefore their thermal motion is negligible. Initial density of the medium is taken to be constant and medium ahead of the shock front is at rest with small counter pressure. Here the particles behave like a pseudo-fluid. Maintaining the equilibrium flow condition in the flow field, the analytical expressions for the shock velocity, shock strength, pressure, and flow velocity have been derived. The variation of flow variables with propagation distance (r), mass concentration of solid particles in the mixture (kp) and the ratio of the density of solid particles to the initial density of gas (G) are obtained and discussed through figures. The results accomplished are compared with those for dusty ideal gas Yadavet, al. 28

In this research we demonstrate the synthesis of pristine tris(8-hydroxyquinoline) aluminium (Alq3) and nickel-doped Alq3 nanorods as well as their characterization. The thermal vapour transport method was used to synthesize nanomaterials in the morphology of nanorods. The surface morphology was studied using scanning electron microscopy (SEM). The structural properties were analyzed using X-ray diffraction. UV-Visible and photoluminescence (PL) spectroscopy were used to examine the optical characteristics. Doping of Ni introduced ferromagnetic properties in the Alq3 and also retained its semiconductor properties. Ni-doped Alq3 nanorods are useful for the development of spintronics devices.

In this paper, we have reported the calculated results of anisotropy parameter (Pl) and angular momentum transfer parameter (L) for positron (electron) scattering by Calcium (Ca) atom using close coupling approximation method in the framework of R-matrix theory at 20eV. Since this theory has deep root in nuclear physics, it also provides better results in atomic and molecular physics. The authors have compared the reviewed results with available theoretical results. A good agreement between these results shows that the present method gives better understanding for the positron (electron)-atom scattering.

The present paper reveals that the potential of China clay and Fly ash were used as adsorbent for the removal of heavy metals such as Ni(II) and Mo(VI) from known concentration of waste water was investigated. Hence the study indicates that the low cost adsorbent of China clay is used for removing 90% and 69% of Ni(II) and Mo(VI) respectively. Fly ash used for removing 84% and 77.6% of Ni(II) and Mo(VI) from wastewater from the initial metal ion concentration of 4.26x105 M and 1.49x105M solution respectively. Batch adsorption studies demonstrated that the adsorbents had significant capacity to adsorb Ni(II) and Mo(VI) from aqueous solution. It was found that the adsorption increased with increase in contact time. Also, percentage adsorption depends on change in pH of N(II) and Mo(VI) solution.

The study of optical properties such as the optical band gap and refractive index of zinc tellurite glass were studied. Zinc Tellurite glasses doped with Er3+ ions were synthesized by varies researcher. The glasses were characterized by X- ray diffraction, optical absorption and photoluminescence spectra. The glassy nature of zinc Tellurite host glass has been confirmed through XRD measurements. The glasses doped or co-doped with rare-earth ions have generated much interest due to the possibility of several promising applications such as optical data storage, visible laser, fibre amplifier, optical communication and sensor devices

Graphene, a unique allotrope of carbon, has garnered a huge amount of attention amongst researchers as its unique properties and promising applications in various real-life domains like in efficient batteries, solar cells, medicinal technologies, environmental remediation, circuit boards, lighting and display, and anti-corrosion has resulted in its commercial exploitation and implementation in everyday life. Since 2004 graphene has been one of the most beautiful scientific and technological achievements. The unique electronic cloud forming the bond between different carbon atoms in graphene leads to several inquisitive questions raised in the field of quantum physics. Till now graphene has been exploited for its electronic and optical properties but new research has shown that phononic properties of graphene will lead to the development of “killer” practical applications in the future. In this review article we have explored the structure, properties and the phononics of graphene with a special reference to few-layer graphene (FLG) and graphene Thermal Interface Materials (TIMs).
