Adsorption of xenon on single-walled (10,10) carbon nanotubes at a temperature of 95 K has been studied by molecular simulation and the results have been compared with recent experiments [A. Kuznetsova, J. T. Yates, Jr., J. Liu, and R. E. Smalley, J. Chem. Phys. 112, 9590 (2000)]. Simulations indicate that adsorption…
Consumption of hot chips is a convenience food in most countries. Unfortunately, these are high in fat and contribute to fat-related diseases in societies with a high fat consumption. There is substantial scope through best-practice deep-frying techniques for producing lower fat, high-quality chips. From a review of t…
Naturally occurring gem opals would seem to be the inspiration for the recent explosion of work on three-dimensionally ordered macroporous, or “3DOM” materials. Myriad techniques have been developed for the creation of 3DOM products. This work focuses on ordered metal oxides and the effects that the chemistry behind p…
Microcontacts on adjacent grains of polycrystalline Fe‐doped SrTiO 3 samples have been used to locally investigate the properties of individual grain boundaries. Impedance spectroscopy was employed to separate bulk and grain boundary impedances. Experiments at about 30 different grain boundaries permit far‐reaching co…
Modeling magnetic components for simulation in electric circuits requires an accurate model of the hysteresis loop of the core material used. It is important that the parameters extracted for the hysteresis model be optimized across the range of operating conditions that may occur in circuit simulation. This paper sho…
The organization of nanoparticles into superstructures of predefined geometry is an important challenge in the area of nanoscale architecture. Attractive Coulombic interaction between positively charged amine groups on gold particle surfaces and negatively charged phosphate backbones of DNA molecules (see Figure) driv…
The organophilic montmorillonite clay and poly(ethylene oxide) (PEO) nanocomposites were intercalated by a solvent casting method using chloroform as the cosolvent. The prepared nanocomposites were characterized by an X-ray diffraction method to examine their microstructure. Rheological properties of both the PEO/clay…
In the last decade, great progress has been made in atomic-layer synthesis of high-temperature superconductors (HTS) and related oxides. Achievements include growth of single-crystal films of various HTS phases, precise multilayers and superlattices, the first artificial HTS compounds, and superconductor-normal metal-…
Novel metal nanoparticles of Pd and Pt were prepared by sonochemical reduction of solutions containing H 2 PtCl 6 or K 2 PdCl 4 . The effect of atmospheric gas on the particle size distribution was investigated. Average diameters and standard deviations of the Pd particles prepared under Ar (Pd/Ar) and N 2 (Pd/N 2 ) w…
Several group contribution methods to estimate the aqueous solubility of organic molecules are proposed and evaluated for their ability to predict the water solubility of new molecules. The learning set consisted of 1168 organic compounds with experimental data taken from the literature after critical evaluation. The…
In this paper, we present the results of variations in the bulk solvent type and the addition of cosolvents on the growth rate of metallic copper nanoparticles produced through a reduction reaction within AOT reverse micelles. The metallic copper particles were characterized using both UV−vis spectroscopy and TEM micr…
Sol-gel electrochemistry is gaining popularity as a versatile general method for the production of inorganic-organic electrodes and electrochemical sensors. Carbon-ceramic electrodes constitute a fine example that demonstrates the disadvantages, capabilities and promise of sol-gel electrochemistry. The compositions, c…

The defect structure of undoped and Sn-doped In2O3 (ITO) materials was studied by preparing powders under different processing environments and performing neutron powder diffraction. The effect of tin doping and oxygen partial pressure was determined. Structural information was obtained by analyzing neutron powder dif…
Two new methods of preparing thin porous metallic films, based on controlled co-crystallization of latex microspheres and gold nanoparticles, have been developed by these authors. The new materials show interesting optical properties and excellent surface-enhanced Raman spectroscopy (SERS) activity. The Figure shows a…
Recent progress in the production, purification, and experimental and theoretical investigations of carbon nanotubes for hydrogen storage are reviewed. From the industrial point of view, the chemical vapor deposition process has shown advantages over laser ablation and electric-arc-discharge methods. The ultimate goal…
A transparent ZnO homostructural light-emitting diode (LED) with a structure of Au electrode/p(i)-ZnO film/n-ZnO single crystal/In electrode was fabricated using the technique of N 2 O plasma-enhanced pulsed laser reactive deposition. The contact between the p(i)-ZnO layer and n-ZnO wafer was found to exhibit nonlinea…
We have tried to establish a relationship between the raw material and the mechanical properties of ceramic pieces subjected to different firing processes, so under the determinant of the thermal process we have done a follow up on the petrogenetic process that the manufacture of ceramics represents. This is evaluated…
Although there are many research studies about plaster strengthened with glass fibre E in Spain, there are no publications which advise the users (plasterers, manufacturers of prefabricated blocks or suspended ceilings, etc) about the most appropriated types of fibre E in respect to its dispersebility degree in the ma…
