Structural transformation from the herringbone structure to the preferentially oriented lamellae under the elongational flow has been studied by the two-dimensional small-angle X-ray scattering (2d-SAXS) technique. For this purpose, thermoplastic elastomer SBS (polystyrene- block -polybutadiene- block -polystyrene) tr…

The exact pattern of residual stresses will depend on the heat treatment temperatures employed, the depth of hardening and the type of quenchant. Process conditions that give rise to compressive residual stresses on the surface of heat-treated components are favourable. This type of residual stress delays the initiati…

A recently developed high coordination lattice based Monte Carlo method is applied to investigate the glass transition of free-standing atactic polypropylene thin films. In this method the short-range interactions are described by a rotational isomeric state model and the long-range interactions are obtained from a di…

We have applied the blue-violet laser in developing several technologies for the next-generation digital versatile disk (DVD). We are convinced that four items, i.e., large capacity, high data-transfer-rate, cyclability, and portability, are equally important. We have set targets for capacity and data-transfer-rate. S…

Due to the large compressibility of gas bubbles, layers of a bubbly liquid surrounded by pure liquid exhibit many resonances that can give rise to a strongly nonlinear behavior even for relatively low-level excitation. In an earlier paper [Druzhinin et al., J. Acoust. Soc. Am. 100, 3570 (1996)] it was pointed out that…

A methodology is demonstrated for creating responsive polymer surfaces that can alter their wetting characteristics when exposed to a humid environment. For this, we take advantage of the surface partitioning of block copolymers at the polymer/air interface and utilize a hydrophilic group at the end of the surface-act…

Solvent free emeraldine base/epoxy resin coating was prepared employing liquid aliphatic polyamine as the "solvent" for emeraldine base(EB) as well as the "hardener" for epoxy resin(EPR). EB/EPR Coatings with EB loading of 1-2wt% showed good corrosion prevention on mild steel either in 0.1 M HCl solution or in 3.5wt%…

The development of phase change optical recording requires better understanding of the crystallization kinetics of recording materials. Most of the existing simulation methods are based on two-dimensional crystallization models. In this work, we develop a new method to simulate the crystallization of phase change reco…

A mark simulation tool for fast-growth phase-change materials was developed to predict the formation and erasure of amorphous marks in phase-change discs that are based on doped Sb 2 Te compositions. One of the main challenges of such a simulation tool is the accurate determination of the input parameters. The thermal…

Ice IV was prepared in a reproducible manner on heating high-density amorphous ice (HDA) at pressure of 0.81 GPa up to ≈162 K at a slow rate of ≈0.5 K min -1, quenching thereafter to 77 K, and recovering the sample under liquid N 2 at 1 bar. Recovered ice IV was characterized by X-ray diffraction and it was free of HD…

Abstract The correlation between the modulus of elasticity, on the one side, and Vickers microhardness and total microhardness, on the other side, was analyzed in the case of ultrahigh molecular weight polyethylenes. An extension of the application of the power relation between microhardness and the modulus ( MH = aE…

We have probed the temperature and magnetic-field dependence of the thermopower and resistance of a p-type silver chalcogenide, Ag2−δTe. The application of a magnetic field causes not only a large magnetoresistance but also a giant magnetothermopower effect. The maximum change of thermopower is as high as 470 μV/K in…

The thermomechanical stability of a system composed of a metallic cap layer on top of a low-k thermosetting polymer film is investigated. It is observed that, when metal layers with high compressive stresses are used, a stress relaxation takes place during thermal anneal at temperatures above 300 °C through buckling o…
