An atomistic step of growth to a faulted loop, a stacking fault tetrahedron (sft) and a void by clustering of vacancies in fcc metals was studied by molecular dynamics computer simulation with an isotropic EAM potential due to Daw and Baskes [1]. In aluminum, a tri-vacancy relaxes to the Damask-Dienes-Weizer structure…

Abstract Volatile organic compounds and organochlorine species liberated by UV exposure of poly(vinyl chloride) (PVC) siding samples have been identified and preliminary quantification made. These volatiles included those remaining in a PVC sample after weathering or laboratory UV exposure and which could be released…

Instantaneous normal modes (INM) are the harmonic approximation to liquid dynamics. This is an extension of the phonon description of lattice dynamics, in which case Bloch's theorem shows that all modes are extended. Long-range order is destroyed in liquids and glasses, and the INM spectrum has contributions from both…

Three established methods for deriving the surface energetic parameters for calcite were studied. These are based on the contact angle in air using various wetting liquids, and submerged systems in water and in alkanes. Two variations of these methods that require less elaborate experimental procedures were also explo…

Summary The hardening of soils containing little clay content has often been related to the cementing of skeleton grains. In sandy‐loam soils from the southern plain of the Chad basin the skeleton grains of the hard horizon are coated and bonded by wall‐shaped bridges. We have studied the bonding agent by X‐ray diffra…

The martensitic - austenitic phase transformation of a polycrystalline shape memory alloys (SMA) occurs gradually over a range of temperatures even though the monocrystal undergoes a first-order transition (at a single temperature). Factors such as material inhomogeneities and internal stresses in a polycrystal are be…

The oxidation of phosphorus by sulfur at low temperatures (<100 °C) has been shown to produce complex mixtures that include 12 of the 17 known binary phosphorus sulfides. Two of these 17 sulfides have been observed in these mixtures for the first time. The rate-determining and first step in the reaction appears to be…

A benchmark study on several closed-form solutions for the mean crushing strength and the cutting resistance of plated structures during collision or grounding is carried out by comparing theoretical solutions with experimental data. Based on expressions which have been derived for unstiffened structures, an extension…

The effect of annealing on the permeation of oxygen, nitrogen, and carbon dioxide through coextruded linear low-density polyethylene (LLDPE) films is studied. The results indicate that the permeability coefficient P of nitrogen does not show a definite dependence on the time of annealing, t a, whereas for the other ga…

Conformational polymorphism of an oligothiophene the title compound (T4S), is reported for the first time. Efficient synthesis of T4S produced, in addition to the triclinic, deep orange crystals reported previously, a second (yellow, monoclinic) form of T4S, whose structure as revealed by single‐crystal X‐ray diffract…

Strain‐dependent electrical conduction has been observed in the system NiO–CaO. x NiO·(1 ‐ x )CaO solid solutions are fabricated by a traditional solid‐reaction method. When the 0.03NiO·0.97CaO solid solution is annealed at 1000°C, excess NiO is excluded and precipitates on the surface or intergrain layers. When compr…

A new and effective method for developing ultralow-loss glasses for long-distance optical fiber systems is presented. The idea is based on the observed strong effect of a very small amount of alkaline or alkaline-earth impurities on structural relaxation of “frozen-in” density fluctuations. Efficiency of this method i…

Luminescence induced by fracture has been observed in rare earth element-doped hexacelsian ( BaAl 2 Si 2 O 8 ). The color of the luminescence varies depending on the kinds of doped rare earth element. Eu 2+ -doped hexacelsian exhibits a luminescence of blue or green color. Sm 2+ - and Sm 3+ -doped hexacelsians exhibit…

Electroless copper deposition has been shown to be a viable technique for the fabrication of very large scale integration (VLSI) interconnections. In particular, electroless deposition was found to be able to fill the high aspect ratio features in submicron VLSI technologies. In this work one‐ and two‐dimensional mode…

Intumescent chemical systems are designed to swell into a thick, robust foam upon exposure to heat, protecting the underlying material from fire by providing a physical barrier to heat and mass transfer. The mechanisms determining the fire-resistant properties of these materials are not well understood. Various approa…
