  • Synthesis and characterisation of nanostructured barium cuprate thin films

    Thin films of Ba1−y CuO2+x system were prepared by DC magnetron sputtering technique, using a BaCuO2 target sintered at 850°C for 24 hours. The sputtering was performed under 0.04 Torr Ar-pressure and at 500 V-135 mA target current. The effect of substrate and substrate bias on the morphology of the films was investigated. The films were characterised by atomic force microscopy (AFM), X-ray ...

  • New frontier in thin film epitaxy and nanostructured materials

    Nanomaterials hold the key to the success of nanotechnology. This review starts with a new paradigm for thin film growth based upon matching of integral multiples of lattice planes across the film-substrate interface. This paradigm of domain matching epitaxy (DME) unifies small as well as large misfit systems utilising the concept of systematic domain variation. By controlling the kinetics of ...

  • Comparative analysis of the thin-film desalination plant process

    Thin-film installations with different heating surface orientations are widely used in seawater technology. Despite the presence of various thermal schemes and the construction of evaporating devices for installations of this type, comparisons of their power output are not available. We have carried out a comparison of the thermal schemes of MSF and thin-film installations in order to determine ...

  • Walmart turning to thin-film solar for new installations

    Walmart (Bentonville, AR) announced that it plans to expand its renewable energy development initiatives through the adoption of thin-film solar technology at a number of its solar power development sites. The company is in the process of adding solar generating systems at 20 to 30 facilities in California and Arizona, and many of these sites will feature thin-film technology, the ...

  • Corrosion protection with synergistic LBL/Ormosil nanostructured thin films

    Stratified systems comprising an inhibitor-doped layer-by-layer (LBL) clay-polyelectrolyte overcoated with a dense organically-modified silicate (Ormosil) are investigated as corrosion protectors for aluminium. As separate coatings, neither the LBL nor Ormosil films were found to provide adequate corrosion protection of the underlying metal. A combination of the two coating methods was found to ...

  • Breakthrough curves of oil adsorption on novel amorphous carbon thin film

    A novel amorphous carbon thin film (ACTF) was prepared by hydrolyzing wood sawdust and delignificating the residue to obtain cellulose mass that was subjected to react with cobalt silicate nanoparticle as a catalyst under the influence of sudden concentrated sulfuric acid addition at 23 °C. The novel ACTF was obtained in the form of thin films like graphene sheets having winding surface. The ...

  • A study of the annealing atmosphere effects on the electrical properties of graphene-incorporated direct-patternable ZnO thin films

    An improvement in the electrical properties of the films is absolutely required for the application of ZnO thin film in electrical devices. And the conventional dry etching process is accompanied by the generation of physical defects, degradation of the properties. The electrical property of direct-patternable, graphene-incorporated ZnO thin film prepared by photochemical solution deposition was ...

  • Low Energy Biological Nitrogen Removal by Cation Exchange, Thin Film Oxygen Transfer, and Heterotrophic Nitrification in Sequencing-Batch, Packed-Bed Reactors

    Sustainable solutions for biological nitrogen removal (BNtR) in wastewater require new treatment process concepts to lower energy requirements. A novel configuration of six packedbed, flood and drain (PFAD) reactors were used in a pilot study to remove nitrogen from a manufactured wastewater comprised of urea, cheese whey, and well water. The reactors operated in a sequencing-batch manner in ...
