The scattering matrix, differential cross section, and total cross section for supramicrometer-size nematic droplets in a polymeric matrix are derived in the anomalous-diffraction approach. Scattering patterns are calculated in detail for three different nematic-director configurations: one characteristic of a droplet…

Dense ‘‘diamondlike’’ hydrocarbon films (a-C:H) are a class of amorphous solids which can be condensed as thin films from nonequilibrium environments by several plasma deposition techniques. Films with hydrogen atom fractions from 0.5 to 0.6 select a structure with an average coordination number close to the theoretic…

A single-crystal Lorentz correction is derived for the case of a general scan through an out-of-plane reflection on a four-circle diffractometer with relaxed sample-to-detector collimation. When the Lorentz correction is expressed in terms of the incremental steps in the Eulerian setting angles, structure amplitudes o…
α-titanium single crystals, containing three different amounts of interstitial impurities, have been tested in compression at temperatures between 77 and 700 K. The mechanical behaviour is characterized by a strong temperature dependence of the yield stress for slip on the primary prismatic slip plane (1010)[1210], a…
In the directional solidification of concentrated alloys, the frozen solid region is separated from the melt region by a mushy zone consisting of dendrites immersed in the melt. Simultaneous occurrence of temperature and solute gradients through the melt and mushy zones may be conducive to the occurrence of salt-finge…
An explicit form of the spin-adapted multireference coupled-cluster formalism in the linear approximation is developed for the special case of a two-dimensional model space involving only closed-shell-type configurations. The formalism is applicable to a number of quasidegenerate systems with two valence orbitals of d…

Summary The fundamental, pore-level mechanisms of foam generation are investigated in monodisperse bead packs. First, direct visual observations identify the following generation mechanisms: lamella leave-behind, gas-bubble snap-off, and lamella division. Then, to ascertain the relative importance of these mechanisms,…

A new switching process was observed in surface stabilized ferroelectric liquid crystals. The switching is associated with a third stable state in addition to the well-known bistable states. The appearance of the third state is characteristic of materials with a large spontaneous polarization and is caused by minimizi…
We perform an accuracy analysis of several possible reflectance–difference (RD) configurations that are compatible with standard molecular-beam epitaxy (MBE) growth chambers, and describe in detail an optical-bridge system that can determine relative changes in RD signals as small as 5×10−5 under standard growth condi…

The atomic bonding configurations of carbon bonding in diamond and diamondlike thin films are explored using Raman scattering. The general aspects of Raman scattering from composites are presented. Effects are discussed due to crystalline or amorphous structures, large versus microcrystalline domains, and strong optic…
There is now a new series of high-temperature superconductors that may be represented as (A(III)O)(2)A(2)(II)Can-1CunO2+2n where A(III) is Bi or Tl, A(II) is Ba or Sr, and n is the number of Cu-O sheets stacked consecutively. There is a general trend toward higher transition temperatures as n increases. The highest n…
