Multilayer systems comprising brittle materials can exhibit substantially different behaviors under flexural and tensile loadings. The present article addresses the origins of such differences, with emphasis on the modeling of the flexural stress–strain response. Systems with both a deterministic tensile strength and…
The numerical approach, proposed by us in the accompanying papers, is applied here to simulate the plastic response of a 2D idealized elasto-plastic body under conditions of loading with constant strain rates. Various kinetic and structural aspects of plastic flow are extensively studied. The results of numerical simu…
The first synthesis of the corrole ring by self-condensation of a monopyrrolic unit is reported. The reaction occurs only in the presence of cobalt ions; it leads to the formation of (triphenylphosphine)(5,10,15-triphenyl-2,3,7,8,12, 13,17,18-octamethylcorrolato)cobalt(III), [Co(OMTPC)PPh3] and represents the first ex…

To obtain polystyrene grafted to mica, a free-radical initiator 2,2'-azobis(isobutyramidine hydrochloride) (AIBA) was attached by ion exchange to the surface of an ultrahigh specific surface area (ca. 100 m<sup>2</sup>/g) muscovite mica powder, and the resulting material was used as an initiator to polymer…
Aluminum (Al) and Al alloys exhibit unusual passivity when immersed in alkaline lithium (Li) salt solutions. This passivity is a result of precipitation of a continuous, polycrystalline talc coating. Talc coatings persist when removed from the Li salt solution and offer increased corrosion protection during exposure t…
The distribution of radial energy deposition around the track of carbon, aluminum, and iron ions with energy range from 10 MeV to 10 GeV inside silicon was calculated. A simple and direct approach was developed utilizing a corrected semianalytical model. The results of the present work agree very well with Monte Carlo…

Convection of adsorbed surfactant along a fluid particle surface can accumulate surfactant at the trailing end of the particle. The nonuniform surface tensions that result cause Marangoni stresses which retard the surface mobility. This is the second part of a two-part study on controlling the mobility of surfactant l…

Calculations of a total energy function are used to describe a theory of hysteresis effects in crystalline, ferromagnetic materials. This model is applied on the cubic structure of FeSi crystals, which are oriented in a (110)[001] texture. The magnetic energy of the crystal is separated in reversible and irreversible…
Summary The ElectroScan environmental scanning electron microscope (ESEM) enables wet samples to be observed by eliminating air but allowing water vapour into the sample chamber. However, evaporation from, and condensation on, the sample may occur during the pumpdown sequence used to reach this state, which means that…

During that time, contr…
The three-dimensional structure of a ligand-free closed form of the glucose/galactose binding protein from Salmonella typhimurium has been determined at a resolution of 1.9 A. The crystallographic R-factor for the refined structure is 17.9%. The model contains all the atoms of the 309 residues of the protein sequence,…
High-purity aluminium nitride (AlN) powders of submicron size were consolidated to almost theoretical density in minutes at 1800°C using a plasma-activated sintering (PAS) process. The structure and microchemistry of grain boundaries in this polycrystalline material (average grain size, about 0.43 μm), sintered withou…
Abstract The adsorption of cadmium and zinc ions on natural bentonite heat‐treated at 110°C or at 200°C and on bentonite acid‐treated with H 2 SO 4 (concentrations: 0·5 mol dm −3 and 2·5 mol dm −3 ), from aqueous solution at 30°C has been studied. The adsorption isotherms corresponding to cadmium and zinc may be class…
