The expansion factors for the mean-square end-to-end distance and radius of gyration are studied for the helical worm-like (HW) chain with the excluded-volume effects incorporated in the Yamakawa–Stockmayer scheme. In this scheme, approximate closed expressions for them are expressed in terms of the excluded-volume pa…

We review the crystallography, band structure, and optical, electrical, and magnetic properties of diluted magnetic semiconductors (DMS), with emphasis on ternary alloys of the type AII1−xMnxBVI (e.g., Hg1−xMnxTe). Considerable attention in the review is given to spectacular novel effects which arise from the selectiv…

Because the atmospheric corrosion products that form on the surface of Al, Zn, and AlZn hot-dip coatings on sheet steel are difficult to characterize, they have not been extensively studied In the past. In this study, the composition and structure of products formed in industrial and marine environments were identifie…

Ceramics of undoped SrTiO3 and BaTiO3 (at T > Tc) show a pronounced Maxwell-Wagner relaxation at ultra low frequencies. This indicates thin nonconducting barrier layers at the grain boundaries and some residual conductivity in the grain. Degradation of the ceramic starts when the electrical field, which develops at th…

The defect structure in 3 mol% Y‐TZP was studied by correlated internal friction, dielectric loss, and ionic conductivity experiments. A prominent mechanical and dielectric loss peak occurs in the temperature range between 380 and 550 K that depends on the frequency of measurement. The relaxation parameters were deter…

Abstract Model butanediol–MDI–polypropylene oxide polymers have been synthesized to explore the structure–property relationships in urethane/polyether polymers. The results of mechanical, thermal, and spectroscopic analyses agree remarkably well. The phase mixing in these polymers decreases with increasing hard‐segmen…

Electrical conduction phenomena in polyimide (Kapton) films were studied with particular attention devoted to the separation of interface and bulk phenomena. The measurements were carried out with a variety of methods in the temperature range of 50 to 270 °C at electrical fields of 104 to 6×105 V/cm and at time interv…

Abstract Various acidic compounds were tested as potential initiators of the cationic polymerization of L,L ‐dilactide. Regardless of solvent and temperature only trifluoromethanesulfonic acid and methyl triflate proved to be useful initiators. With methyl triflate as initiator L,L ‐dilactide polymerizes faster than d…
