Mechanism of Thermally Induced Morphological Reorganization and Lamellar Orientation from the Herringbone Structure in Cross-Linked Polystyrene-block-polybutadiene-block-polystyrene Triblock Copolymers

Shinichi Sakurai、Sakae Aida、Shigeru Okamoto 等 5 位作者2003-02-28Macromolecules

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…

Analysis of residual stresses in main crankshaft bearings after induction surface hardening and finish grinding

Janez Grum2003-02-28Proceedings of the Institution of Mechanical Engineers Part D Journal of Automobile Engineering

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…

Monte Carlo simulation on the glass transition of free-standing atactic polypropylene thin films on a high coordination lattice

Guoqiang Xu、Wayne L. Mattice2003-02-28The Journal of Chemical Physics

A recently developed high coordination lattice based Monte Carlo method is applied to investigate the glass transition of free-standing atactic polypropylene thin films.

A Review of Optical Disk Systems with Blue-Violet Laser Pickups

Takeshi Maeda、Motoyasu Terao、Takeshi Shimano2003-02-28Japanese Journal of Applied Physics

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…

Nonlinear wave interactions in bubble layers

С. В. Карпов、Andréa Prosperetti、Lev A. Ostrovsky2003-02-28The Journal of the Acoustical Society of America

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…

Smart Polymer Surfaces

Spiros H. Anastasiadis、Haris Retsos、Stergios Pispas 等 5 位作者2003-02-28Macromolecules

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…

Three Dimensional Crystallization Simulation and Recording Layer Thickness Effect in Phase Change Optical Recording

Zhaohui Fan、David E. Laughlin2003-02-28Japanese Journal of Applied Physics

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…

Determination of the Crystallisation Kinetics of Fast-Growth Phase-Change Materials for Mark-Formation Prediction

Erwin R. Meinders、M.H.R. Lankhorst2003-02-28Japanese Journal of Applied Physics

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…

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…

Giant magnetothermopower associated with large magnetoresistance in Ag2−δTe

Young Sun、M. B. Salamon、M. Lee 等 4 位作者2003-02-28Applied Physics Letters

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…

Compressive stress relaxation through buckling of a low-k polymer-thin cap layer system

Francesca Iacopi、Sywert Brongersma、Karen Maex2003-02-28Applied Physics Letters

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…
