The interest in quantum dot sensitized solar cells (QDSSC), which has theoretically proved to have up 44% energy conversion efficiency recent years, is growing rapidly. Although it high value, PCE obtained studies with QDSSCs far from these values. This situation shows that there are many difficulties be solved QDSSC technology. One of the main challenges technology irradiated load recombinatio...

Several in vitro methods have been developed over the years to improve correlation between screening tests and usage tests of dental restorative materials. Pulpal responses to restorative materials in usage tests are usually less severe than are responses of cells either in vitro screening tests or in implantation tests where there is direct contact between experimental materials and vital cell...

The low quantum yields and lack of visible light utilization hinder the practical application of TiO2 in high-performance photocatalysis. Herein, we present a design of TiO2 nanopillar arrays (NPAs) decorated with both Au and Pt nanoparticles (NPs) directly synthesized through successive ion layer adsorption and reaction (SILAR) at room temperature. Au/Pt NPs with sizes of ~4 nm are well-disper...

TiO(2) hollow fibers with high surface area were manufactured by a simple synthesis method, using natural cellulose fibers as template. The effective light scattering properties of the hollow fibers, originating from their micron size, were observed by diffuse reflectance spectroscopy. In spite of the micrometric length of the TiO(2) hollow fibers, the walls were highly porous and high surface ...

Semiconductor-sensitized NiO photocathodes have been fabricated by successive ionic-layer adsorption and reaction (SILAR) deposition of CdS, CdSe and cascaded CdS/CdSe onto mesoscopic NiO films. Detailed morphological and structural characterization reveals that the growth of CdS and CdSe on mesoscopic NiO electrodes results in the formation of crystalline and conformal layers under ambient con...

Abstract Copper iron sulfide (CFS) (chalcopyrite) thin-film electrodes have been synthesized for energy storage applications using the SILAR method without use of a binder. The film’s structural as well morphological and electrochemical characteristics were studied to check effect varying deposition cycles. x-ray diffraction (XRD) test reveals crystalline tetragonal CuFeS 2 with decreasing peak...
