ABSTRACTHigh performance polymer network gels consisting of tetra-arm poly(ethyleneglycol) (Tetra-PEG) gels were fabricated via a module assembling method and their mechanical properties and structure were investigated by stretching and compression measurements, dynamic mechanical measurements, and small-angle neutron scattering (SANS). It was found that Tetra-PEG gels are nearly-ideal polymer network with negligible fractions of defects and entanglements. SANS intensity functions indicated that the network structure was uniform free from spatial inhomogeneities. It is deduced that this uniform structure is ascribed to its unique preparation method, i.e., module assembling method (cross-end-coupling of tetra-functional macromers with complementary functional groups). Characteristic properties originated from the near-ideality as polymer networks are demonstrated, including its application to ion gels, i.e., polymer network in ionic liquid.

High Oxidation Resistance

Recently, the use of refractory metal silicides as low resistivity, high temperature and high oxidation resistance gate materials in large scale integrated circuits (LSI) has become an important approach in advanced MOS process development (1). This research is a systematic study on the structure and properties of molybdenum silicide thin film and its applicability to high performance LSI fabrication.

Abstract During nature evolution process, living organisms have gradually adapted to the environment and been adept in synthesizing high performance structural materials at mild conditions by using fairly simple building elements. The skin, as the largest organ of animals, is such a representative example. Conferred by its intricate organization where collagen fibers are arranged in a randomly interwoven network, skin collagen (SC), defined as a biomass derived from skin by removing non-collagen components displays remarkable performance with combinations of mechanical properties, chemical-reactivity and biocompatibility, which far surpasses those of synthetic materials. At present, the application of SC in medical field has been largely studied, and there have been many reviews summarizing these efforts. However, the generalized view on the aspects of SC as smart materials in non-medical fields is still lacking, although SC has shown great potential in terms of its intrinsic properties and functionality. Hence, this review will provide a comprehensive summary that integrated the recent advances in SC, including its preparation method, structure, reactivity, and functionality, as well as applications, particularly in the promising area of smart materials.
