We present an efficient method for calculating the reflectivity of three-dimensional gratings on multilayer films based on a finite-element, Green's function approach. Our method scales as NlogN, where N is the number of plane waves used in the expansion. Therefore, it is much more efficient than the commonly adopted…

We propose a guided-mode resonant grating (GMRG) filter using silicon-on-insulator wafer. In the fabrication, electron beam lithography and fast atom beam etching are used. The periods of the three filters are 680, 700, and 720 nm, respectively. The reflectivity is measured to be nearly 100% at the wavelength of 1502…

Abstract Summary: The behaviour of a flexible polymer chain in solvents of variable quality in dilute solution is discussed both in the bulk and in the presence of an adsorbing wall. Monte Carlo simulations of coarse‐grained bead‐spring models and of the bond fluctuation model are presented and interpreted in terms of…

Simple equations are derived that give the shapes of various convex polyhedra. The five regular polyhedra, called Platonic solids (the tetrahedron, hexahedron or cube, octahedron, dodecahedron and icosahedron), and polyhedra composed of crystallographically low-index planes are treated. The equations also give shapes…

The interaction of Bel-7402 hepatocellular carcinoma cells (HCC) as a single cell suspension with hydroxyapatite (HAP) nanoparticles was investigated. It was observed by an inverted microscope that the cells were still homogeneously distributed in the culture medium after 24 h. A TEM analysis showed that the HAP nanop…

ABSTRACT Polymer nanocomposites are an emerging class of multifunctional materials that have not been optimized for their functional potential. As a part of a series of studies conducted by Wong and collaborators [1-6], a novel processing design for polymer nanocomposites using ball milling and nanoscale graphite plat…

A methodology for the numerical simulation of bird strike on a novel leading edge (LE) structure of a horizontal tail plane is presented. The innovative LE design is based on the ‘tensor skin’ concept, comprising one or more folded composite sub-laminates that unfold during the bird impact, thus providing high-energy…

Phase transitions in a partially fluorinated compound, MHPO(13F)BC, have been studied by optical microscopy, calorimetry and miscibility methods. Spontaneous polarization (PS), helical pitch measurements, and frequency-domain dielectric study, have also been carried out. These studies indicate the presence of an inter…

High thermal conductivity aluminum nitride (AlN) substrates were prepared by aqueous tape casting. The characteristics of surface‐treated AlN powder were studied in aqueous ball‐milling media. The oxygen content of AlN powder with the dispersant was lower than that of AlN powder without the dispersant at the same ball…

Droplets of oil containing oleic acid were observed to spread, then recoil, on an aqueous solution of sodium hydroxide. Surfactant is produced at the interface during spreading, and for reagent concentrations of order O(1mM) spreading is observed to be much faster than in the absence of a chemical reaction [radius R(t…

The effect of Re segregation on the α-Fe Σ5 [001] (010) grain boundary (GB) is investigated by using a software called DMol and discrete variational method (DVM). Based on the Rice–Wang model, the calculated segregation energy and defect formation energy show that Re is a strong cohesive enhancer. We also calculated t…
