    Opis:
    The electrical characterization of the Al/p-Si/P3HT/Ag organic-on-inorganic diode was done by current-voltage, capacitance-voltage and conductance-voltage methods. The values of ideality factor and barrier height of the diode were determined from the current-voltage characteristics and found as 2.32 and 0.77 eV, respectively. These values were also determined from Cheung's functions and Norde's method due to the non-ideal behavior of the diode. The electronic parameters obtained from the various methods indicate a good consistency with each other. The density of interface states for Al/p-Si/P3HT/Ag organic-on-inorganic diode was found to be $7.64 × 10^{10} cm^{-2} eV^{-1}$. The obtained electrical parameters of the Al/p-Si/P3HT/Ag organic-on-inorganic diode are higher than that of the conventional Ag/p-Si Schottky diodes. This indicates that the electrical properties of the silicon Schottky diodes can be controlled using organic interfacial layer.

    Opis:
    Electrical characteristics of the heterojunction fabricated by thermal deposition of copper phthalocyanine (CuPc) on an n-silicon substrate have been investigated. The frequency has significant effect on capacitance (C), conductance (G) and series resistance $(R_{s})$ interface states $(D_{it})$ of the junction. Measured capacitance and conductance were corrected for $R_{s}$. The conductance technique was used to measure the density of the interface states. This method revealed the value of the interface state density distribution for the Au/n-Si/CuPc/Au interfaces of the order of $10^{12} cm^{-2} eV^{-1}$.

    Opis:
    A chelating resin based on Salicylic acid-Formaldehyde copolymer, containing Orcinol (SFO), has been synthesized and characterized on the basis of Elemental Analysis, Particle Size Distribution, FT-IR Analysis, XRD, SEM and Optical Photographs. The Physico-Chemical properties have been studied. This resin is highly stable in acidic and alkaline solutions and has been studied as a chelating sorbent for heavy metal ions and transition metal ions. The Exchange capacity order is Ni(II) > Cu(II) > Zn(II) > Cd(II) > Pb(II). The effect of nature and concentration of different electrolytes on distribution coefficient (Kd) for metal ions have been investigated. Separation of synthetic mixtures containing Cu(II)-Pb(II), Ni(II)-Cd(II) and Brass constituents has been carried out using a column prepared from the synthesized chelating resin. The developed procedure was also tested for the removal of Cd(II) and Pb(II) from natural water of Purna River near by Navsari, Gujarat, India. Keywords

    Opis:
    Granular materials have vast applications both in industry and in daily life. They display quite interesting and exceptional properties different from the other known forms of matter. To investigate the complex properties of particulate materials, experimental, analytical, and numerical techniques have been employed. In this paper the results of experimental and numerical tests of various grain sizes and coefficient of friction between granules and cylindrical walls on the mass measured at bottom of container, known as apparent mass, are reported. It is revealed that apparent mass augments with the grain size. Moreover, it is also found that the variation in apparent mass measurement is strongly dependent on bead diameter rather than the silo size. The results suggest that the conversion of vertical stresses into horizontal in silo is mainly due to the friction between the grain and system boundary than the arching phenomenon.
