      Polymers and composites (pages 7–9)

      Prof. Hermann Mark

      Article first published online: 15 SEP 2004 | DOI: 10.1002/adma.19900020102

      High performance composites used for example in the aerospace industry have come about through the application and development of the principles used to improve polymers. The interaction of crystallinity, crosslinking, and the incorporation of rigid chains is discussed and a critical view of the future given by one of the pioneers of modern polymer science.

    1. Electrochromic Materials for optical switching devices (pages 10–16)

      Dr. Klaus Bange and Dr. Thomas Gambke

      Article first published online: 15 SEP 2004 | DOI: 10.1002/adma.19900020103

      Adjustable adsorption and reflectance of visible and near infrared wavelength light is a property of electrochromic materials which make possible active optical filters, smart windows and a number of display technologies. The materials, both inorganic, e.g. WO3, and organic, e.g. viologens, are incorporated into electrochromic devices (ECDs). The different approaches to ECDs (see Figure) are discussed and thed materials used reviewed.

    2. Superconductivity—then and now (pages 16–22)

      Dr. Herbert Jaeger

      Article first published online: 15 SEP 2004 | DOI: 10.1002/adma.19900020104

      The discovery of high-Tc superconductors in 1986 resulted in a massive research effort which continues today. Superconducting materials have been known, however, since 1911. In this article, the historical background to superconductivity is traced, conventional and high-Tc materials are described and the theories which are applied to rationalize this phenomenon discussed, always with an eye on current and future applications, for example SQUIDs and levitating trains.

    3. The transduction of host-guest interactions into electronic signals by molecular systems (pages 23–32)

      Prof. David N. Reinhoudt and Dr. Ernst J. R. Sudhölter

      Article first published online: 15 SEP 2004 | DOI: 10.1002/adma.19900020105

      The integration of molecular receptors and field effect transistors (FETs) gives a device that can convert substrate activity into coherent electronic signals, thus connecting the chemical and electronic domains. The selective complexation of cationic species by receptor molecules (for example, see figure) can be incorporated into planar IC technology through use of a CHEMFET, a chemically sensitive FET. The chemistry and technology of this fascinating field are reviewed.

    1. A new effect in second harmonic generation by poled nematic films (pages 33–36)

      Shlomo Yitzchaik, Dr. Garry Berkovic and Prof. Valeri Krongauz

      Article first published online: 15 SEP 2004 | DOI: 10.1002/adma.19900020106

      Poled nematic films, where the asymmetric axis responsible for second harmonic generation (SHG) is not in the poling direction are reported. Liquid crystalline polymers containing dopant chromophores, or side chain groups with high molecular hyperpolarizabilies exhibit this effect which has potential applications in nonlinear optics.

    2. Phase behavior of discotic liquid crystalline polymers and related model compounds (pages 36–40)

      Wolfgang Kranig, Dr. Bernhard Hüser, Prof. Hans W. Spiess, Dr. Willi Kreuder, Prof. Helmut Ringsdorf and Herbert Zimmermann

      Article first published online: 15 SEP 2004 | DOI: 10.1002/adma.19900020107

      The phase behavior of liquid cyrstalline polymers and oligomer model compounds with alkylated tripheylenes (see figure) as the mesogenic core is studied using a combination of optical microscopy, DSC and 2H NMR. The information provided by NMR provides unique insights into the behavior of liquid crystalline phases.

    3. Control of polymorphism by ‘tailor-made’ polymeric crystallization auxiliaries. Preferential precipitation of a metastable polar form for second harmonic generation (pages 40–43)

      Dr. Eugen Staab, Prof. Lia Addadi, Prof. Leslie Leiserowitz and Prof. Meir Lahav

      Article first published online: 15 SEP 2004 | DOI: 10.1002/adma.19900020108

      Polar crystals can display pyroelectricity, piezoelectricity and frequency doubling leading to second harmonic generation. These metastable polar polymorphs can be selectively precipitated to the exclusion of stable, non-polar forms by the use of polymeric crystallization auxiliaries. The approach is based on the hypothesis that crystal nuclei assume structures very similar to those of the crystals into which they develop.

    1. Making A1 A15s (pages 43–45)

      Prof. Robert W. Cahn

      Article first published online: 15 SEP 2004 | DOI: 10.1002/adma.19900020109

      A15 Intermetallic superconductors do not receive as much media hype as the high-Tc ceramic variety but they are big business, especially in the superconducting magnets area. This rapidly growing research field which includes melt-spinning and rapid solidification technology is surveyed, and a report of the synthesis of Nb3Ge with critical currents of 5 × 1010 and 8 × 1010 A/M2 at fields of 0 and 15 T respectively is reviewed.

    2. Biomaterials hightlights IV. The “state of the art” (pages 45–49)

      Prof. Günther Heimke

      Article first published online: 15 SEP 2004 | DOI: 10.1002/adma.19900020110

      This edition of our regular series on biomaterials focused on the progress reported at two major conferences held in September, 1989, in Heidelberg, FRG. Aspects of the use of metals, cements, ceramics, glasses and coating in hard tissue replacement are discussed along with new developments in the study of cell attachment to implant surfaces.
