  • Friction and Adhesive Wear Study of Flame Sprayed Nickel Base Powder
    • Authors: Sushil Kumar, Shashi Prakash Dwivedi, Satpal Sharma
      Pages: 79 - 82
      Abstract: Nickel base alloys are being widely used to improve the abrasive and adhesive wear resistance of various industrial components. In the present investigation, commercially available Ni-base (nickel-base) powder (MEC 1260) was used for coating deposition. The coating was deposited by flame spraying process. The microstructure of the flame sprayed coating mainly showed Ni-cells surrounded by eutectic. The Ni (nickel), Cr (chromium) and Fe (iron) were uniformly distributed in the coating while the distribution of boron was found along the grain boundaries. The Rockwell hardness of the coating was found as 56±8 (HRc). Sliding wear resistance of coating is 3-4 times higher than substrate.

    • Authors: Ahmed I. Adawy
      Pages: 83 - 90
      Abstract: In this study, different cationic surfactants were prepared by esterfication of different fatty acids with ethanol then amidation of the prepared esters with N, N dimethyl ethylene diamine then quaternized the tertiary amines with benzyl bromide to produce a series of quaternary ammonium salts (cationic surfactants). Surface tension at four different temperatures of these cationic surfactants was investigated. The surface parameters including critical micelle concentration (CMC), the lowest concentration of surfactants at which micelles are present, maximum surface excess (Γmax), the number of surfactant molecules at the interface, minimum surface area (Amin) area occupied by each molecule, efficiency (pC20) of surfactant concentration that suppresses surface tension by 20 dyne/cm and surface pressure at CMC (πCMC), were studied and the thermodynamic parameters such as free energy of micellization (ΔGomic), the work of transfer of surfactant molecules to the bulk of a solution to form micelles and adsorption (ΔGoads), the work of transfer of surfactant molecules from the bulk of a solution to the surface, enthalpy (ΔHo m) total heat content of the system in micellization process, (ΔHoads) total heat content of the system in the adsorption process and entropy (ΔSom) the degree of disorder in the system in micellization, (ΔSoads) and the degree of disorder in adsorption were calculated. The antimicrobial activity of the prepared surfactants was determined via the inhibition zone diameter against different microorganisms also against sulfate reducing bacteria (SRB) by the dilution method.

  • Electronic and Transmission Properties of Low Buckled GaAs Armchair
    • Authors: B. P. Pandey
      Pages: 91 - 95
      Abstract: The electronic and transmission properties of N atom width (N: 4, 8, 12, 16)low-buckled (LB) armchair GaAs hydrogen (H) passivated nanoribbons (NA GaAs NRs) are studied with the help of first-principle theory. In low buckled armchair GaAs nanoribbon, quantum confinement effect is observed due to which all of the investigated NA GaAs NRs with H passivated are found to be semiconducting. The fundamental direct band gap at k-point Г (gamma) have been calculated, which exhibit interesting width dependent (N: 4~16) behaviour of bandgap. The H passivated edge of NA GaAs NRs with different width of nanoribbons provides great flexibility to modulate fundamental bandgap. The transmission coefficient is calculated from which thermal conductance has been calculated forall width of GaAs armchair nanoribbon.

  • Magnetic and Thermal Studies of Zn Doped Forsterite Ceramic Nanomaterial
    • Authors: B. Karthikeyan, N. Rajamanickam
      Pages: 96 - 100
      Abstract: The present study emphasizes the unique magnetic and thermal properties of nano-ceramic forsterite (pure and Zn doped) powder synthesized by mechanical activation technique and subsequent annealing, using the raw materials talc, periclase and zinc oxide. The structural properties of the samples were studied using XRD technique. The magnetic measurements of pure and the cation Zn2+ substituted samples were done by using Vibrating Sample Magnetometer (VSM) at room temperature. The hysteresis (M-H) curves were obtained for both the samples and they clearly show the existence of ferromagnetic behavior of the as synthesized samples. The results of VSM analysis show that the saturation magnetization (Ms), the coercive field (Hc) and retentivity (Mr) were found to be increased with Zn doping. The values of Ms for the undoped and doped forsterite nanomaterials are found to be 9.47 × 10-3 emu/g and 13.68 × 10-3 emu/g respectively. The thermal behaviour of the samples was investigated using Differential Scanning Calorimetry (DSC) technique over a temperature range of 30-450°C. The specific heat capacities for the samples were also calculated using the DSC data.

    • Authors: M. Mohamed Musthafa, G. Sridharan
      Pages: 101 - 105
      Abstract: This study describes preparation of biodiesel through micro emulsification of diesel with 15, 25 and 35% of used mustard oil and 2.5% of Triton-X100 as surfactant by volume. The prepared blends are designated as B15; B25 and B35.The physiochemical properties of blends were tested as per American Society for Testing and Materials (ASTM) standard and compared their properties with diesel. Experiments were conducted on single cylinder, 4 strokes, water cooled direct injection diesel engine fuelled by three different micro emulsified fuel blends. The results indicated that a slight decrease in the brake specific energy consumption and increase in brake thermal efficiency for B35 fuel compared to diesel fuel operation. Reduction in HC, CO2, CO and nitric oxide emission was observed for all test fuels compared to diesel fuel.

  • Efficient Micellar Extraction of Ternary Mixture of Cationic Dyes from
           Aqueous Medium
    • Authors: Narinderjit Kaur, Sangeeta Sharma, Ekta Khosla
      Pages: 106 - 114
      Abstract: In the present work an attempt has been made to extract ternary mixture of Basic Yellow-2 (BY-2), Basic Red-12 (BR-12) and Basic Blue-26 (BB-26) dyes from simulated textile effluent by solvent extraction using anionic surfactant Sodium Dodecylsulfate (SDS). This study proposes an efficient, fast, simple and effective microemulsion system for the removal of cationic dyes using reverse micelles of anionic surfactant from wastewaters. In this method, dyes are dissolved in aqueous phase and mixed with organic solvent in the presence of surfactant. The effects of the concentration of feed mixture (dye and surfactant), temperature, pH and salt concentration on extraction of dyes from aqueous phase have been studied after the complete separation of two phases. The method poses no environmental threat, so it is an eco-friendly way to treat dye house effluents.

  • Enhanced Dielectric Properties of Polypropylene based Composite using Zinc
           Oxide Nanorods Filler
    • Authors: D. J. Sharmila, J. Brijitta, R. Sampathkumar
      Pages: 115 - 120
      Abstract: Polypropylene and zinc oxide nanorods composites were prepared by combination of solution and mixture melting methods. Dielectric properties of the composite thin films were studied to see if zinc oxide nanorods have effect on the dielectric properties of polypropylene thin film. Introduction of zinc oxide nanorods at low filler content in the polypropylene matrix significantly improves the dielectric constant of the matrix. Simultaneously the structure of the composites was characterized by UV, XRD and SEM to understand the features in the structure that determine the functionality of the material. Composites with different weight percentage of zinc oxide nanorods show better absorption in the UV region compared to polypropylene matrix. This is due to the inherent capability of nano zinc oxide to absorb in the UV region. X-ray diffraction pattern of nanocomposites show sharp and highly intense peaks whereas neat polypropylene shows less intense peaks. This may due to the development of crystallinity in the polymer. Uniform distribution of zinc oxide which have a width of around 160-200 nm is observed in the SEM photographs of composites.

  • Microstructural and Mechanical Properties of Cu-based Alloy Manufactured
           by Self-Propagating High-Temperature Synthesis Method
    • Authors: Y. Amiour, K. Zemmour, D. Vrel
      Pages: 121 - 126
      Abstract: Microstructure and properties of Cu1-xZn1-yAl1-z ranging through (0.29 <X< 0.30; 0.74 <Y< 0.75; and 0.83 <Z< 0.96) alloys obtained by the Self- propagating High-temperature Synthesis (SHS) were examined. The microstructural and mechanical properties were examined, respectively by X-ray diffraction, tensile tests and Brinell hardness. The obtained results showed that the modification of composition lead to the formation of new phases. Therefore, this microstructure affects strongly the mechanical properties of the selected samples. In this study, we will also highlight the SHS technology and prove that it can alternate the conventional methods regarding the development of a Shape Memory Alloys (SMAs).

  • Physicochemical Investigation on the Pulmonary Surfactant of Some
    • Authors: Suvasree Mukherjee, Clive A. Prestidge, Sandra Orgeig, Amiya Kumar Panda, Satya Priya Moulik
      Pages: 127 - 136
      Abstract: Large aggregate (LA) fraction of the pulmonary surfactant (PS) isolated from five different animals of the vertebrate group, lungfish, chicken, crocodile, stumpie lizard and guinea pig were isolated and characterized. Active pulmonary surfactant components were obtained by chloroform-methanol extraction of the saline suspended LA fraction. Total phospholipid (PL) and protein content were estimated biochemically by standard enzymatic methods. A systematic progression in the PL and protein content was noticed with the developmental sequence of the animals, except the crocodile, which could be due to the difficulty in the PS isolation procedure. In vitro functionality of the solvent spread film was carried out in a Langmuir surface balance by way of surface pressure (π)-area (A) measurements. PS from all the species exhibited reversible compression and expansion cycles. A clear correlation between the maximum attainable surface pressure (πmax), also known as the collapse pressure (πc) and the developmental sequence, with some exceptions, could have been established. Langmuir-Blodgett deposits, transferred onto freshly cleaved mica, were imaged by atomic force microscopy for the five different species. DPPC enriched domains showed different dimensions for the five different species. The comprehensive set of studies shed light on the composition, film functionality and structure of the pulmonary surfactants of the vertebrates where a correlation with the evolution sequence is observed.
