Dye-sensitized solar cells (DSSCs) based on titanium dioxide (TiO2) have been extensively studied because of their promising low-cost alternatives to conventional semiconductor based solar cells. DSSCs consist of molecular dye at the interface between a liquid electrolyte and a mesoporous wide-bandgap semiconductor ox…
The recipe of silicone glass sealant was studied, and the influence of crosslinking agent, plasticiser and reinforcing agent on its property was investigated. After compositing the glass sealant with polytetrafluoroethylene (PTFE) nanoparticles, a novel superhydrophobic silicone/PTFE glass sealant was obtained with co…
The nature of water adsorption on TiO 2 (110) rutile surface attracts a lot of attention for quite some time. In spite of the considerable experimental and theoretical efforts a lot of details remain unclear. We have been using work function study to follow the adsorption of water on TiO 2 at room temperature, and int…
Silver ions (Ag+) used as secondary ion, cetyl trimethyl ammonium bromide (CTAB) used as surfactant and ascorbic acid(AA) used as reducing agent, the gold(Au) nanorods were synthesized by seed-mediated growth method. The resulting substrates have been characterized by UV-vis spectroscopy. The law of Au nanorods growin…
In the past few years, recycled asphalt materials have been used successfully in asphalt concrete pavement in China. However, there are no results of the performance of using abson method and vacuum rotating reclaim to recycled asphalt. The objective of this study is to investigation of recycled asphalt materials perf…
In the present research, we have mainly concentrated on the survey of interactions in Ln 3+ (Ln = La, Ce, Nd, and Sm) ternary complexes of 5,7-dichloroquinoline-8-ol (DCQ) and 4-vinyl pyridine (VP), [Ln(VP) 2 (DCQ) 3 ] 3+ by means of density functional theory, Hartree-Fock and Sparkle/PM3 semi-empirical computational…
The title Sm(III)-erythritol complex, [Sm(NO3)3(C2H6O)(C4H10O4)], is isotypic with its Nd, Eu, Y, Gd, Tb and Ho analogues. The Sm(III) cation exhibits a coordination number of ten and is chelated by a tridentate erythritol ligand and three bidentate nitrate anions. It is additionally coordinated by an O atom of an eth…
Abstract. The phonon spectrum of zigzag h-BN nanoribbons with the edges passivated by hydrogen atoms under tensile strain along the axis direction were calculated by first-principle calculations. It is found that the uniaxial strain can lead to a narrow frequency range of lattice vibration modes. But it hardly affects…
To investigate the effect of CaCO3 concentration and velocity on scaling fouling process on plain and SOFT, experiments have been done at different CaCO3 concentration and velocity on the two kind tubes. The results are that the homogeneous nucleation rate and the growth rate are both increase when CaCO3 concentration…
Single walled carbon nanotube (SWNT) field effect transistors (NTFETs) are quickly becoming the foundation for bioelectronic sensors. We describe a multimodal NTFET device that could be used as a real time single cell biosensor with the potential for chemical, optical and electrical sensing capabilities. This device u…
The fiber shaped monoclinic tungsten oxides with high preferential orientation has been synthesized by dialysis and aging treatment at room temperature, of the white precipitates prepared from HCl acidified (NH4)10W12O41 solution. The microstructure evolution of the above tungsten oxide was studied by SEM. The morphol…
The template polymerization of aniline in the presence of polymeric sulfonic acids of various structures and their mixtures is studied. In the latter case, the dominant effect of a polyacid on the kinetics of aniline polymerization and the electronic structure of the resulting polyaniline complex is observed. As shown…
Deposition of Ti-Si-C thin films by magnetron sputtering was examined using elemental targets of titanium, silicon and carbon, in order to investigate the effects of substrate temperature on the formation of carbide compounds such as TiC x and/or Ti 3 SiC 2 , and thereby on mechanical properties and on physical proper…
This study investigates optical properties as a function of internal and external fields in the quantum well (QW). Optical properties of CdZnO/MgZnO QW structures, considering various applied electric fields are evaluated by using many-body effects. The strain-induced piezoelectric polarization and the spontaneous pol…
Comparison of microstructures between LPSed and SSSed SiC ceramics were made. Several kinds of structure defects for LPSed SiC were emphasized to discuss. They related with whole flow path of processing, compositional design of powder mixture, spray granulation of powder mixture, milling, shaping, and sintering contro…
Zinc oxide (ZnO) is a one of the most interesting compound semiconductors that received more attention during last few years due to its unique properties. Due to that, this study has been done to manipulate those properties to be used for FET applications. The ZnO thin film has been deposited using the thermal chemica…
A novel and simple approach is reported to fabricate ZnO nanorods. Zinc acetate dihydrate, ethanol and de-ionized water were used to prepare seed layer. Zinc nitrate and hexamethylenetetramine solution were used for growth of ZnO nanorods. The ZnO nanorods were grown at two different temperatures of 90°C and 120°C and…
Li-doped zinc oxide (ZnO) films were deposited on nucleation side of freestanding diamond (FSD) films by the radio frequency magnetron sputtering method.
