We have incorporated chain stiffness and correlations between neighboring bonds into a self-consistent field (SCF) lattice model for end-attached polymer layers (commonly known as ‘‘brushes’’). An increase in the chain stiffness leads to an increasing brush height. This increase is directly related to the change of th…

A third-order geometric aberration theory of the ellipsoidal grating has been developed by analytically following an exact ray-tracing formalism with the aid of power series expansions. The theory takes into account all the possible aberrations up to third order and provides analytic formulas for the spot diagram of a…

The finite element method (FEM) is introduced to numerically model near-field diffraction devices using Maxwell's equations. This method is commonly used in the antenna and microwave communities to analyze scattering and waveguiding problems, but is not yet popular in the optics community. Its advantages are the rigor…

Experimental results are presented on subcritical crack growth under sustained and cyclic loads in a HIPed Si 3 N 4 at 1450°C and a hot–pressed Si 3 N 4 –10 vol% SiC w composite in the temperature range 1300°–1400°C. Static and cyclic crack growth rates are obtained from the threshold for the onset of stable fracture…

On the basis of a model similar to that of Su, Schrieffer, and Heeger, we investigate transitions between bipolaron and polaron states in doped heterocycle polymers such as polypyrrole, polythiophene, and polyselenophene. The dopant impurity is assumed to be located between chains, and the interchain coupling is due t…

Abstract An in situ FTIR study of the reduction of NO by propylene in O2 has shown that the reaction on the Rh/Al2O3 surface at 623 K leads to the formation of IR bands assigned to adsorbed hydrocarbons, -NCO, -CN, -NO+, -CO32− and CO2 species. The intensity of the bands depends on the reaction time and the presence o…

Based on the RBAO technology, low‐shrinkage mullite/SiC/ Al 2 O 3 /ZrO 2 composites were fabricated. A powder mixture of 40 vol% Al, 30 vol% A1 2 O 3 and 30 vol% SiC was attrition milled in acetone with TZP balls which introduced a substantial ZrO 2 wear debris into the mixture. The precursor powder was isopressed at…

Summary X‐ray detection by energy‐dispersive spectrometry in the analytical electron microscope (AEM) is often limited by low collected X‐ray intensity ( P ), modest peak‐to‐background ( P/B ) ratios, and limitations on total counting time (τ) due to specimen drift and contamination. A new AEM has been designed with m…
