Abstract The preparation and isolation in the solid state of five aryl 1,2,3,5‐dithia‐ and diselenadiazolyls is reported. The structure of the dimer of 4‐ClC 6 H 4 CN 2 S 2 in the solid state was obtained: monoclinic, C2/c with Z = 8, a = 20.982(10), b = 10.058(3), c = 15.867(6) Å, β = 93.34(4)°, R = 0.066, R w = 0.…

Single- and three-phase broad-beam x-ray attenuation data have been obtained using lead, steel, plate glass, gypsum wallboard, lead acrylic, and wood. Tube voltages of 50, 70, 100, 125, and 150 kVp were employed and the resulting curves were compared to transmission data found in the literature. To simplify computatio…

Abstract SBR compounds containing ground vulcanizates of known composition and cure state were prepared and the cure behavior studied. Decreases in scorch times and maximum rheometer torques were observed when ground vulcanizates were added to the SBR compounds. Two primary phenomena are proposed to explain these find…

We report the results of a theoretical study of the interaction between aluminum and poly(p-phenylenevinylene) and derivatives of poly(p-phenylenevinylene). This allows us to investigate the initial stages of formation of the metal/conjugated polymer interface. Applying the semiempirical Austin model 1 method, we find…

The Jiles-Atherton (J-A) model is applied to the problem of describing the dynamics of a nonlinear circuit driven by a square wave voltage source and comprising a linear resistor and capacitor in series with a nonlinear inductor, whose core displays saturation and hysteresis. The presence of hysteresis is shown to inc…

Corrosion behavior of grade 550 (X-80) pipeline steel with coating disbondments was studied in a range of bicarbonate (HCO3−) solutions using a potentiodynamic polarization technique. Corrosion morphology of the steel was examined using optical and scanning electron microscopy. The shape of the polarization curves and…

Migration of a small drop of liquid, initially at rest on a level, solid surface, can be induced by means of thermocapillary forces. If a temperature gradient is imposed across the solid, it has the effect of diminishing the surface tension on the warmer side of the droplet. Consequently, migration manifests itself as…

b 29 Si and 27 Al MAS‐NMR were performed on NaOH‐activated blast‐furnace slag to better characterize the amorphous and poorly crystalline phases which occur in this system. The unreacted glass has a mainly dimeric silicate structure represented by a broad 29 Si peak (FWHM = 15 ppm) centered at –74.5 ppm [ Q 1 ], with…

The conversion of phosphazene high polymers to useful materials depends on the development of methods to cross-link the macromolecular chains. A number of cross-linking routes have been used, including chemical, photochemical, and high energy radiation techniques. The relationship of the cross-linking processes to ele…

Assuming a saturated ferromagnet, the anomalous crystal structures of the magnetic 3d transition elements Fe, Co, and Ni are explained from simple band-filling arguments. The full-potential linear muffin-tin orbital (FP-LMTO) method is used to calculate the elastic constants (${\mathit{C}}_{11}$, ${\mathit{C}}_{12}$,…
