Abstract Miocene volcanic rocks from northeast of Lopburi, Thailand, include a suite of highly potassic (<6.3% K 2 O) perlitic rhyolites that are similar chemically to rhyolites from Sardinia (which are also perlitic) and Vulcano. Electron microprobe analysis using a defocussed beam has shown that glass composition…
Hydrophobic compounds of smectic liquid crystals are spontaneously spread on a liquid surface to form softly-condensed monomolecular films. The constituent molecules are coherently tilted from the surface normal when they form smectic-C phase in the bulk state, while the molecules are aligned perpendicular to the surf…
In order to explore the utilization of persimmon juice-dyed T-shirts under vigorous sports activities, persimmon juice-dyed and undyed cotton knitted T-shirts were compared in terms of comfort-related physical properties such as moisture transport characteristics and wear performances including sweat amount, moisture…
Polylactide (PLA) filaments produced by melt spin-drawing in different conditions (draw ratio, temperature of the draw roll) have been studied to demonstrate the influence of the process conditions on the tensile properties of the PLA filaments. Draw ratio varies from 2 to 3.5 and temperature of the draw roll from 80°…
Abstract A new hexanuclear copper(II) sandwich complex based on two 12‐membered macrocyclic methylsiloxanolate ligands, [Cu 6 {(MeSiO 2 ) 6 } 2 ] · 6DMF, was synthesized and characterized by single‐crystal X‐ray diffraction analysis and magnetic measurements. The cluster compound crystallizes in the monoclinic system,…
We demonstrate a simple method for growing organic crystal fiber bundles as long as centimeters by controlling the shape and dimension of the evaporation channel of the chloroform solution of N,N'-bis(1-ethylpropyl)-3,4,9,10-perylenebis(dicarboximide) (EPPTC). The capillary effect induces a thin solution film (capilla…
The question of the statistical accuracy of EBSD data for global texture calculation was re-explored on the basis of a very large grain population (83 000 grains measured on a recrystallized low-alloyed Zr sheet). Previous works aimed mainly at identifying and quantifying the main texture components and were based on…
The vibrational configuration interaction method used to obtain static vibrational (hyper)polarizabilities is extended to dynamic nonlinear optical properties in the infinite optical frequency approximation. Illustrative calculations are carried out on H(2)O and NH(3). The former molecule is weakly anharmonic while th…
A practical approach for adsorption modeling of heterogeneity of single-walled carbon nanotube (SWNT) bundles has been developed. The method integrates experimental analysis with grand canonical Monte Carlo (GCMC) simulation of a small probe molecule, such as nitrogen at 77 K. Using this method, it is possible for one…
Abstract Ag nanoparticles of two different sizes (1 and 4 nm) were prepared within an apoferritin cavity by using an Ag + ‐loaded apoferritin as a nanoconfined environment for their construction. The initial amount of Ag + ions injected in the apoferritin cavity dictates the size of the final Ag particles. The protein…
Epitaxial thin films of ZnMn 2 O 4, grown from an aqueous solution on (100) and (111) spinel MgAl 2 O 4 substrates, have been topotactically reduced and leached to produce epitaxial rock salt MnO on the same substrates. The volume change accompanying the conversion of ZnMn 2 O 4 to 2MnO associated with a loss of Zn an…
Abstract Different ink‐jet printed paper materials were investigated using X‐ray photoelectron spectroscopy (XPS) yielding the elemental composition of the near‐surface region of the papers. We found significant differences with respect to the detected elements and their atomic concentrations in the different inks stu…
In this study, we investigated the relationship between the fabric drape coefficient from the drape meter and mechanical properties tested on the fabric assurance by simple testing system (FAST). Different kinds of woven fabrics with two kinds of weave (plain and twill) were tested. Three regression models are propose…
Epitaxial ultrathin titanium dioxide films of 0.3 to approximately 7 nm thickness on a metal single crystal substrate have been investigated by high resolution vibrational and electron spectroscopies. The data complement previous morphological data provided by scanned probe microscopy and low energy electron diffracti…
Abstract Castor oil (CO) based polyurethane (PU)– polyester nonwoven fabric composites were fabricated by impregnating the polyester nonwoven fabric in a reactive composition containing CO and diisocyanate. Composites were fabricated with two different isocyanates such as toluene‐2, 4‐diisocyanate (TDI) and hexamethyl…
In the past few years, reconstruction methods have been developed and applied successfully to restore the beta microtexture in titanium alloys. This contribution shows how these methods are extended to other transformations often encountered in advanced titanium alloys: the alpha (hcp)-->gamma (tetragonal) and the bet…
The thermal stability and hydrogen desorption kinetics for MgH 2 and Mg 2 NiH 4 before and after doping with TiF 3 or Ti(OBu n ) 4 were studied by X-ray diffraction, differential thermal analysis, thermogravimetry, Fourier transform infrared spectroscopy, and X-ray absorption spectroscopy techniques. Unlike the previo…
Sodium phosphate tellurite glasses in the system (NaPO(3))(x)(TeO(2))(1-) (x) were prepared and structurally characterized by thermal analysis, vibrational spectroscopy, X-ray photoelectron spectroscopy (XPS) and a variety of complementary solid-state nuclear magnetic resonance (NMR) techniques. Unlike the situation i…
Au@Ag and Ag@Au core−shell nanoparticles were synthesized using sequential laser ablation of metal targets in water. The resulting core−shell particles were then exposed to iodine or 1,6−hexanedithiol. For the Ag@Au + I 2 → Au@AgI and Au@Ag + dithiol → Ag@Au−dithiol reactions, inversion of the core−shell structures re…
In this work, the potential of low-viscous branched polymers for gas separation applications such as CO 2 absorption from flue gas is examined. Carbon dioxide and nitrogen solubilities are measured at low pressures for linear and branched polyethers, hyperbranched polyesters, and polyamines such as a polyamidoamine an…
