This paper presents an extensive literature review and assessment of corrosion failure mechanisms encountered during accelerated tests of microelectronic devices. The failure mechanism of primary emphasis is electrolytic metal migration. The metallurgies of interest are silver, gold, copper, and aluminum. Electrochemi…
The ability of a drop to stick to a solid surface is investigated when the surrounding fluid is in motion. The specific problem analysed consists of a small drop on a planar surface immersed in a second immiscible fluid which is flowing parallel to the solid surface at a constant rate of strain. An expression is obtai…
The formation of Al 2 TiO 5 has been studied in equimolar Al 2 O 3 ‐TiO 2 powder mixtures of ∼1μm particle sizes and moderate purity (∼99.8 wt%) at temperatures around 1300°C, where the free energy of formation is very small. Micro‐structural development and reaction kinetics indicate that different mechanisms operate…
The literature which describes the microstructural development during neutron irradiation of austenitic stainless steels is reviewed, with emphasis on solution annealed AISI 316 stainless steel. The main difference in primary damage caused by fission and fusion neutron irradiation is the considerably larger amounts of…
The effect of heat treatment in the range 633 K–933 K on the phase transformations among three types of phases, i.e. the CsCl (B2)-, rhombohedral (R)- and monoclinic (M)-phases in Ti-49.7, 50.2 and 50.6 at%Ni alloys have been investigated using the differential scanning calorimetry (DSC) method. It has been confirmed…
Abstract A blend system of linear low‐density polyethylene (LLDPE) (ethylene butene‐1 copolymer) with high‐density (linear) polyethylene (HDPE) is investigated by differential scanning calorimetry (DSC), wide‐angle x‐ray diffraction (WAXD), small‐angle x‐ray scattering (SAXS), Raman longitudinal‐acoustic‐mode spectros…
The perovskite solid solutions BaPb1-xBixO3 exhibit unique properties in both metallic and semiconducting phases. In the metallic phase (0 ≤ x ≤ 0.35) they are superconducting with high transition temperatures. It turns out that the high T c originates from extremely strong electron-phonon interaction. At the metal-se…
This report presents the assessed thermochemical measurements on rubidium compounds upon which the property values, Δf H0, Δf G0, S0, C0p, and H0(T)−H0(0) at 298.15 K and Δf H0(0 K) recommended in the ‘‘NBS Tables of Chemical Thermodynamic Properties’’ are based. Included in this set of thermochemical measurements, or…
Abstract
The kinetics of uptake, retention, and radiotoxicity of 125IUdR have been studied in proliferating mammalian cells in culture. The radioactivity incorporated into the DNA is directly proportional to the duration of incubation and to the extracellular concentration of 125I. The rate of proliferation of cells is related…
X-Ray photoelectron spectroscopy (XPS) was used to determine plasma induced chemical species on the surface of polyethylene (PE). Argon plasmas were found to have no detectable chemical effect on the PE surface, whereas oxygen and nitrogen plasmas created new chemical species which altered the chemical reactivity of t…
To crystallize, spherical colloidal particles must not have too broad a spread of size (or polydispersity). Here it is pointed out that the findings of recent calculations and computer simulations concerning the effects of polydispersity on the crystallization of hard spherical particles are simplified considerably if…
This paper reviews all the interactions of hydrogen and deuterium with silica-based optical fibers. Included in the discussion are H2overtone absorption, OH formation, increased UV and IR absorption, radiation effects on H2-treated fibers, the gas-in-glass laser and applications, the reduction of OH absorption by isot…
Diffusion induced grain boundary migration (DIGM) is a phenomenon in which the sideways migration of grain boundaries accompanies the diffusion of solute along them. This results in the deposition of solute in, or its removal from, the matrix through which the boundaries sweep. In this review, the detailed phenomenolo…

Accurate fractional coordinates, (harmonic) thermal parameters and lattice parameters are presented for KDP (KH2PO4) at 293 K, Tc + 5 K and Tc - 20 K, and for ∼95% deuterated DKDP (KD2PO4) at 293 K, Tc + 5 K and Tc - 10 K; and also for KDP and DKDP at 16.5 kbar (at 293 K). The fractional coordinates and thermal parame…
The intensity of the tryptophan fluorescence of the alpha subunits of guanine nucleotide-binding regulatory proteins increases when they bind guanosine 5'-O-(3-thio)triphosphate (GTY gamma S). The kinetics of the fluorescence enhancement and of the measured binding of [35S]GTP gamma S are well correlated. The addition…
