A function of external doping: Characteristics of inorganic nanostructure based diode

The present study has been related to synthesis and characterization of ZnO films growth by chemical spray pyrolysis technique. Variation in the characteristics of ZnO film has been evaluated as a function of Cobalt content. The influence of cobalt content on structural, morphological, optical and electrical features have been observed by XRD, SEM, AFM, UV–vis spectroscopy and I-V measurement, respectively. Structural measurements of the samples indicate that all samples have polycrystalline nature with (002) preferential orientation. SEM and AFM images have indicated that films have smooth and uniform morphology. Changes in the surface morphology of the samples have been explained by taking Cobalt incorporation into consideration. Optical studies reveal that the band gap values of the samples exhibit decreasing tendency with Cobalt content. Performance of ZnO films in Schottky diode application has been conducted by evaporation Au contact on ZnO:Co films. From I-V curves of the devices, it has been observed that all devices exhibit good rectifying properties. Also, some diode parameters such as ideality factor, barrier height have been calculated by considering thermionic emission theory (TE) and have been found in the range of 1.89–1.57 and 0.57–0.62 eV, respectively. Additionally, these results and series resistance values of the diodes have been checked and calculated by using Cheung's function. Results showed that all diode parameters highly depended on cobalt concentration. All results have been discussed in detail depending on cobalt incorporation.     

A Review of Contemporary Views of Theories of Adhesion

The once distinct and independent theories of adhesion have been losing their isolation and converging. Ideas of the effects of surface roughness, once dismissed as irrelevant except in the case of textiles, have been revised; albeit on a smaller scale as details of surfaces have been revealed by sophisticated techniques. Electrostatic interactions across an interface have been more deeply explored and their significance recognised and expounded. Diffusion of groupings and chain segments within a polymer have been related to the possibilities of interaction with a variety of surfaces. Perhaps most important, theories of adsorption have been extended in depth. The precise nature of the molecular interactions have been recognised and quantified. In doing this the contribution of diffusion and elastoplastic phenomena have been integrated. These developments are collated and analysed to present the present understanding of the concepts.     

Differential scanning calorimetry investigation of curing of bisphenolfurfural resins

Bisphenolic resins have been prepared by alkali catalyzed condensation of bisphenol-F, bisphenol-A, and bisphenol-C, respectively, with furfural. The resin samples have been characterized by elemental analysis, dilute solution viscosity measurement, and measurement of number-average molecular weight. Curing reactions of these bisphenolic resins with hexamine have been investigated by differential scanning calorimetry. The overall apparent activation energies for the curing have been found to be 24 ± 2, 34.2 ± 1.9, and 36.8 ± 2.3 kcal/mole for bisphenol-F-furfural, bisphenol-A-furfural, and bisphenol-C-furfural resin, respectively. The curing reactions have been found to follow an overall first-order kinetics.

The individual components have been extracted from the plate and determined colorimetrically by using anthrone reagent. Standard substances of monoesters, diesters and triesters, which have been synthesized from gas-chromatographically pure methyl esters of fatty acids, have been isolated by column chromatography and identified by elemental analysis, colorimetric determination and N.M.R. determination.
