The thermal conductivities of solid layers of thicknesses from 0.01 to 100 μm affect the performance and reliability of electronic circuits, laser systems, and microfabricated sensors. This work reviews techniques that measure the effective thermal conductivity along and normal to these layers. Recent measurements usi…
Cooperative magnetic interactions have been observed in α‐[MnPc][TCNE], which results from the reaction of manganese phthalocyanine with tetracyanoethylene. This is the latest in a series of molecule based materials found to exibit such unusual magnetic behaviour. The α polymorph displays very strong magnetic coupling…

The numerical approach, proposed by us in an associated paper, is further developed here to account for the processes of ordering and disordering in a 2D idealized elasto-plastic body. Study of the kinetic and structural aspects of such processes reveals various features characteristic of the glass transition and stru…
Simplified preparative procedures are described for the generation of α-[PW_(11)O_(39)Cr^(III)(OH_2)]^(4-) and α2-[P_2W_(11)O_(61)Cr^(III)(OH_2)]^(7-) anions which can be readily oxidized, chemically or electrochemically, to α-[PW_(11)O_(39)Cr^(V)O]^(4-) and α2-[P_2W_(17)O_(61)Cr^(V)O]^(7-). The oxidized complexes are…

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…
