Thorough examination of a previous report on the high solubility of carbon nanotubes in refluxing aniline reveals that the reported optical properties of the “nanotube” solution are due to aniline decomposition products, rather than functionalized nanotubes. No appreciable dissolution of single-wall carbon nanotubes c…

The behavior of leakage current and electric field of insulators primarily depends on the environmental stresses. A mathematical analysis based on dimensional analysis technique is applied to develop the correlation of leakage current (LC) and electric field with the physical variables of the environmental stresses. T…

Molecular dynamics modelling has been used to simulate the structures of phopshine-functionalised, silsesquioxane-based dendrimers whose excellent catalytic properties have been previously demonstrated. The effect of changing the chemical composition of the dendrimer branches is simulated. The results indicate that ad…

The terahertz (THz) refractive indices of a liquid crystal 4′-n-pentyl-4cyanobiphenyl (5CB) in both of the nematic and isotropic phases were determined by terahertz (THz) time-domain spectroscopy for the first time, to our knowledge. We find that the extinction coefficient of 5CB is negligibly small in this frequency…

Hybrid sol–gel films were developed for tissue-derived cell growth. Specifically, Buffalo green monkey kidney cells were grown on hydrophobically modified silica sol–gel thin films and on such films in which poly-L-lysine (PLL) was entrapped in order to affect surface positive charge density. Intermediate hydrophobici…

We studied the aging characteristics of the plasma display panel (PDP) containing -coated blue phosphors and the thermal characteristics of coated phosphors. The nanoscale coatings on phosphors were obtained by the sol-gel method for an concentration of 2.0 wt %, pH values from 2 to 4, and a solution temperature of 50…

Proton conductivity measurement and ac impedance analysis of composites were carried out using two different methods to prepare sample powders: mechanical mixing and evaporation to dryness. At temperatures below the superprotonic phase transition temperature of ca. 140°C, the conductivity of the composite prepared by…

Two N-methylphosphonic acid derivatives of a 14-membered tetraazamacrocycle containing pyridine have been synthesized, H(4)L(1) and H(6)L(2). The protonation constants of these compounds and the stability constants of complexes of both ligands with Ni(2+), Cu(2+) and Zn(2+) were determined by potentiometric methods at…

Carbon nanotubes are formed in bulk compositions from thermal decomposition of a cobalt-containing organometallic compound in the presence of an excess amount of a multi(ethynyl)aromatic compound. The novel method described here permits the large-scale production of carbon nanotubes in a shaped, solid configuration. 1…

We report on the synthesis of highly uniform, single phase zinc ferrite films prepared through a single step low temperature reaction by the liquid phase deposition (LPD) method. X-ray diffraction, TGA and EDX measurements support the assumption that the as-deposited films are constituted from a mixture of crystallize…

Micrometric ordered mesoporous silica spheres are synthesised by spray-drying alcoholic sols. For this synthetic route, the important effect of siloxane chemistry on both the morphological and the textural properties of spray-dried silica particles is demonstrated. This is achieved by correlating data obtained on the…
