Abstract Structural chemistry began with Louis Pasteur, who first saw the configuration of molecules manifest in the shapes of crystals. Here is reviewed forgotten, century‐old efforts to make molecular configuration vivid in polycrystalline ensembles. Resorcinol, and a variety of other simple molecular crystals, when…
Barium has been established as an alternate codopant other than conventional aluminum or phosphorous for fabrication of rare‐earth‐ (RE) doped optical fiber through modified chemical vapor deposition (MCVD) coupled with solution doping technique. Different optical and material characterization results of our fabricate…
A multicomponent vaporization model is integrated with detailed fuel chemistry and soot models for simulating biodiesel–diesel spray combustion. Biodiesel, a fuel mixture comprised of fatty-acid methyl esters, is an attractive alternative to diesel fuel for use in compression-ignition engines. Accurately modelling of…
Microstructural investigations by cross section Transmission Electron Microscopy have been carried out on Al-doped ZnO films epitaxially grown on (0001) ZnO and a-sapphire by RF magnetron sputtering, since it is known that crystallographic defects influence the physical properties of ZnO films. Threading dislocations…
Photomagnetism in three-dimensional Co/Fe Prussian blue analogues is a complex phenomenon, whose detailed mechanism is not yet fully understood. Recently, researchers have been able to prepare molecular fragments of these networks using a building block synthetic approach from mononuclear precursors. The main objectiv…
Abstract Nanosized Fe2O3 particles (nano‐Fe2O3) with two shapes (tetrakaidecahedral and grainy) were synthesized by hydrothermal methods. The morphologies and structures were characterized using a combination of experimental techniques including X‐ray diffraction (XRD) and scanning electron microscopy (SEM). Two compo…
Multiwalled carbon nanotubes (MWNTs) were functionalized with four different functional groups and used as nanofillers to reinforce biodegradable polyurethanes (PU), in an effort to explore their effect on the thermal and mechanical properties of the obtained nanocomposites. The PU were synthesized via one step proces…
Recent experiments find the signal of giant nonlocal resistance ${R}_{\mathrm{NL}}$ in $\mathsf{H}$-shaped graphene samples due to the spin/valley Hall effect. Interestingly, when the Fermi energy deviates from the Dirac point, ${R}_{\mathrm{NL}}$ decreases to zero much more rapidly compared with the local resistance…
Recent research has shown that using multiple diverse-bandgap photovoltaic (PV) cells in conjunction with a spectrum splitting optical system can significantly improve PV power generation efficiency. Although volume Bragg gratings (VBGs) can serve as effective spectrum splitters, the inherent dispersion of a VBG can b…
The nitriding process is widely used to improve the tribological properties and wear resistance of metal surfaces. An “edge effect” occurs due to distortions of the electric field around the corners and edges of the components, although the components are well heated. This results in nonuniformity in properties such a…
Band alignment at a MgO/GaSb heterointerface using x-ray photoelectron spectroscopy measurements, Li, Ruxue, Wei, Zhipeng, Liu, Xue, Li, Yongfeng, Fang, Xuan, Tang, Jilong, Fang, Dan, Gao, Xian, Wang, Dengkui, Hao, Yongqin, Yao, Bin, Ma, Xiaohui, Wang, Xiaohua
In this paper, we establish a general formalism to quantify the interaction of electromagnetic waves with mushroom-type structures (high impedance surface and bi-layer) with diodes inserted along the direction of the wires. The analysis is carried out using the nonlocal homogenization model for the mushroom structure…
, avoiding the retardation effect arising in electron energy-loss spectroscopy (EELS). The EELS data differed from the optical data in the energy range of 10-20 eV due to the retardation effect, even though Cerenkov loss was thoroughly suppressed. The calculated differential cross-section indicates that the influence…
The enhancement of light from semiconductors due to surface plasmons coupled resonantly to its emission is limited because of dissipation in the metal and is also restricted by the dielectric characteristics and homogeneity of the metal-semiconductor interface. We report a new mechanism based on electrostatic interact…
Current vertex correction (CVC), the backflowlike correction to the current, comes from conservation laws, and the CVC due to electron correlation contains information about many-body effects. However, it has been little understood how the CVC due to electron correlation affects the charge transports of a correlated m…
The results of high-frequency dielectric measurements with obtained -CuInSe 2 single crystals provided an opportunity to determine the mechanisms of dielectric losses and charge transport, and also to evaluate the density of states at the Fermi level; the average time of charge carrier hopping between localized states…
Abstract We investigate the effect of a strong magnetic field on a three dimensional smectic A liquid crystal. We identify a critical field above which the uniform layered state loses stability; this is associated to the onset of layer undulations. In a previous work García-Cervera and Joo (2012 Arch. Ration. Mech. An…
Efficient Monte Carlo simulations are used to determine the liquid–liquid binodal line of mixtures of hard-sphere colloids and neutral polymers under good-solvent conditions for two values of the polymer-to-colloid size ratio q, q = 0.5 and 1. We use a multiblob coarse-graining approach, in which groups of monomers ar…
The orientation relationships (ORs) between the Al matrix and Si2Hf precipitates with an orthorhombic structure in an Al–Si–Mg–Hf alloy after heat treatment at 833 K for 20 h were investigated by transmission electron microscopy and electron diffraction. Four ORs are identified as (100)Al||(010)p, (0\overline {1}1)Al|…
The paper summarizes in brief applications of perfluoropolymer thin films deposited from the gas phase by several different methods, for protection of various materials and devices both at the research stage and already in industry. Perfluoropolymer films protect from corrosion coated metals, attain superhydrophobic p…
