Abstract The negative electrical field around clay particles whose edge thickness is small relative to the Debye length of the diffuse double layer associated with the planar surfaces may spill over into the edge region. Such a spillover may affect B adsorption by the clay. This study was conducted to determine the ef…

For many electronic applications, the surface of a dielectric polymer must be modified to obtain the desired surface properties, such as wetting, adhesion, and moisture barrier, without altering the bulk properties. This paper reviews wet- process modifications of dielectric polymer surfaces and also presents unpublis…
On the basis of the interaction of dipolar molecules with a liquid surface we calculate the thermodynamics of the molecular orientation and related mechanical and electric effects for a monolayer of molecules on an air-liquid interface. It is shown that compressing the molecular area should lead to a weak first order…

A comparative study of the $^{29}\mathrm{Si}$ spin-lattice relaxation behavior (induced by trace amounts of paramagnetic dopants in the glass) in phase-separated ${\mathrm{Li}}_{2}$${\mathrm{Si}}_{4}$${\mathrm{O}}_{9}$ and monophasic ${\mathrm{Li}}_{2}$${\mathrm{Si}}_{2}$${\mathrm{O}}_{5}$ and ${\mathrm{Na}}_{2}$${\ma…
Abstract Sediments collected at various field locations may have chemical and physical constituents that influence test results and may contain organisms that cannot be readily removed. Thus, reference sediments are needed that can be formulated to match diverse freshwater and estuarine sediments encountered in compre…
A new araphid diatom genus, Synedropsis Hasle, Medlin et Syvertsen, is described from sea ice. The generitype, Synedropsis hyperborea (Grunow) Hasle, Medlin et Syvertsen from the Arctic, was first described as a species of Synedra, as was the antarctic Synedropsis fragilis (Manguin) Hasle, Syvertsen et Medlin. A secon…

Microscopy studies of coexistence droplets of (tilted) surfactant molecules absorbed at air-water interfaces have demonstrated that such droplets contain a variety of textures. In this paper we describe the observed droplet textures using the Landau free energy for tilted hexatic surfactant films, supplemented by a bo…
A major challenge facing the synthetic inorganic chemist is the synthesis of solid materials with specifically designed properties. However, small soluble molecular building blocks with well-defined reaction chemistries which would allow low-temperature assembly into crystalline solid state inorganic materials are not…
Hyper-Rayleigh scattering has been developed as a generally applicable technique for the determination of the first hyperpolarizability β of a wide class of molecules [Clays and Persoons, Rev. Sci. Instrum. 63, 3285 (1992)]. In this article, we show that it is possible to replace the low repetition rate, nanosecond pu…
The study of the effective thermomechanical response of active fibrous composites with shape memory alloy (SMA) fibers is the subject of this work. A 3-D constitutive response for the SMA fibers is formulated first. To model thermomechanical loading path dependence, an incremental approach is used assuming that within…
Morphology, composition, and growth defects of α′‐SiAION have been studied in a fine‐grained material with an overall composition Y 0.33 Si 10 Al 2 O 1 N 15 prepared from α‐Si 3 N 4 , AlN, Al 2 O 3 , and Y 2 O 3 powders. TEM analysis has shown that fully grown α′‐SiAloN grains always contain an α‐Si 3 N 4 core, implic…

The mechanism of TiO2 thin film deposition on single crystal TiO2 by chemical vapor deposition (CVD) using tetrakis(isopropoxo)titanium(IV) (TTIP) has been investigated. The structure of the rutile(100) surface has been shown to form a 1×3 reconstruction using reflection high-energy electron diffraction. Temperature p…
Quasi-elastic light scattering (QELS) was used to investigate quantitatively the mechanisms of nucleation, postnucleation growth, and dissolution in ensembles of both crystalline and amorphous aggregates of satellite tobacco mosaic virus (STMV), ferritin, apoferritin and pumpkin seed globulin. At low supersaturation c…
