This paper explores the effect of the depth-of-cut of an indenter on the phase transformations during nanoscratching on monocrystalline silicon on the Si(100) orientation. The analysis was carried out by molecular dynamics simulations. It was found that the depth-of-cut and the impingement direction of the indenter ha…
The Ce(III) ion in the title complex, [Ce(NO(3))(3)(C(13)H(12)N(4)O)(2)], is 12-coordinated by six chelating nitrate O atoms and six donors (2 O and 4 N atoms) of two N'-[1-(2-pyridyl)ethylidene]isonicotinohydrazide ligands, exhibiting a bicapped pentagonal-antiprism-type coordination geometry. The title complex posse…
In the title complex, {[Cd(C(5)H(6)O(4))(H(2)O)(2)].4H(2)O}(n), the dimethylmalonate-cadmium metal-organic framework co-exists with an extended structure of water molecules, which resembles a sodalite-type framework. In the asymmetric unit, there are five independent solvent water molecules, two of which are in specia…
The synthesis of meso-tetrakis(4-allyl-2,6-dimethylphenyl)porphyrin from 2,6-dimethylaniline is described.
Abstract We prepared starch films by jet‐cooking aqueous dispersions of high‐amylose starch and then allowing the jet‐cooked dispersions to air‐dry on Teflon surfaces. When the starch films were immersed in 1% solutions of polyethylene (PE) in 1‐dodecanol, dodecane, and xylene at 120°C and the solutions were allowed t…
We demonstrated that anodized aluminum oxide (AAO) enables the fabrication of micellar nanotubes and nanopores decorated with nanoparticles. Block copolymer micelles containing precursors of nanoparticles were coated on the nanopores of AAO, from which we were able to select nanotubes containing nanoparticles or nanop…
Abstract In this study, a novel bi‐order model combined with zero‐ and first‐order kinetics was proposed for the decomposition of PMMA (MW = 120,000 g/mol) in concentrated HNO3 by microwave irradiation. To develop and validate this model, Fourier Transform Infrared spectroscopy, scanning electron microscopy, fractiona…
Rodent surgery is often an important component in assessing the utility of engineered tissues. A wide variety of surgical procedures can be performed in common laboratory rats or mice and these quite frequently serve as an intermediate step between bench-top experiments and large animal testing or human trials. Given…
Multi-wall carbon nanotubes (MWCNTs) were grown by spray pyrolysis of acetylene as the carbon source in the presence of Au–Co as catalyst precursors. A high yield of network-shaped carbon nanotubes (CNTs) with further purification has been obtained in the optimal conditions. The optimum synthesis parameters included a…
Abstract 4,4′‐Diazidomethylbiphenyl (DAMBP) and poly(dimethylsilylene‐ethynylenephenyleneethynylene) (PDMSEPE) were thermally polymerized to form a novel silicon‐containing polytriazole resin (PDMSEPE‐DAMBP) by 1,3‐dipolar cycloaddition. Differential scanning calorimetry, FTIR, and 13C‐NMR were used to characterize th…
Ultraprecision diamond-ground silicon wafers were irradiated by a high-frequency nanosecond pulsed Nd:YAG laser equipped on a four-axis numerically controlled stage. The resulting specimens were characterized using a white-light interferometer, a micro-Raman spectroscope and a transmission electron microscope. The res…
In a recent article (Mitsoulis, 2007, “Annular Extrudate Swell of Newtonian Fluids: Effects of Compressibility and Slip at the Wall,” ASME J. Fluids Eng., 129, pp. 1384–1393), numerical simulations were undertaken for the benchmark problem of annular extrudate swell of Newtonian fluids. The effects of weak compressibi…
We present an extensive study of an ultracompact grating-based beam splitter suitable for photonic integrated circuits (PICs) that have stringent density requirements. The 10 microm long beam splitter exhibits equal splitting, low insertion loss, and also provides a high extinction ratio in an integrated coherent bala…
Current polishing pads cannot polish a workpiece without using slurry with free abrasive. The new slurry is required to be continually poured into the working area, so more than half of the slurry may be lost from the table without contacting the wafer surface; this leads to economic and environmental problems. In the…
Abstract In this study, a polar conductive filler [carbon black (CB)], a nonpolar polymer [polypropylene (PP)], and a polar polymer [nylon 6 (PA6)] were chosen to fabricate electrically conductive polymer composites by melt blending and compression molding. The morphological developments of these composites were studi…
Abstract One of the most important properties of clothes is their ability to help the body's thermal system to keep the body temperature in its natural range, even if the environmental conditions or physical activities are outside the body's ideal range. Perspiring is one of the most important effects of physical acti…
Abstract Cardanol‐based novolac resins were separately prepared with different mole ratios of cardanol‐to‐formaldehyde with different acid catalysts. These resins were epoxidized with epichlorohydrin, in basic medium, at 120°C. The resins were, separately, blended with different weight percentages of carboxyl‐terminat…
Fluorescence decay dynamics of photo-excited p-element (Bi, Pb, Sb, Sn)-doped and Al-codoped germanate glasses have been studied over a wide range of time scales and intensities upon excitation with 800 nm and 532 nm short light pulses. Decay of fluorescence contains several components with different spectral and temp…
We synthesized suspended single-walled carbon nanotubes (SWNTs) by the thermal chemical vapor deposition method and functionalized them with Au nanoparticles (NPs). We used 3-(aminopropyl)triethoxysilane as a linker and controlled the Au NP density on the SWNT surface by changing the reaction time. In the Raman scatte…
We investigate the quasiparticle dynamics in the two-orbital Hubbard model on the square lattice at quarter filling by means of the cellular dynamical mean-field theory. We show that the Fermi-liquid state is stabilized up to the large Hubbard interactions in the symmetric case without Hund's coupling, and find the he…
