 3. Nonlinear competition heats up 
  -Four materials that transform light in unusual ways 
    are going head to head in the face to build the
    fastest devices - such as switches for optical 
    communications systems.

   have faster lanes for photons near their perimeters ensuring
   that - unlike step index fibers - all the photons arrive closer
   together.

 6. A Topographic View of Supercooled Liquids and Glass Formation 
   -Various static and dynamic phenomena displayed by glass-forming
    liquids, particularly those near the so-called "fragile" limit, emerge as manifestations of the multidimensional complex topography 
of the collective potential energy function.  These include non-Arrhenius viscosity and relaxation times, bifurcation between the alpha and beta-relaxation processes, and a breakdown of the stokes-einstein relation for self-diffusion.  This multidimensional viewpoint also produces an extension of the venerable Lindemann melting criterion and provides a critical evaluation of the popular "ideal glass state" concept.

 7. The Microscopic Basis of the Glass Transition in Polymers from Neutron Scattering Studies 
  -Recent neutron scattering experiments on the microscopic dynamics of polymers below and above the glass transition temperature Tg are reviewed.  The results presented cover different dynamic processes appearing in glases: local motions, vibrations, and different relaxation processes such as alpha and beta relaxation . For the alpha-relaxation, which occurs above Tg, it is posible to extend the time-temperature superposition principle, which is valid for polymers on a macroscopic scale, to the microscopic time scale.  However, this principle is not applicable for temperatures approaching Tg.  Below Tg, an inelastic excitation at a frequency of some hundred gigahertz (on the order of several wave numbers), the "boson peak", survives from a quasi-elastic overdamped scattering law at high temperatures,  The connection between this boson peak and the fast dynamic process appearing near Tg is discussed.

 8. Spatially Resolved Visible Luminescence of Self-Assembles Semiconductor Quantum Dots 
  -Ensembles of defect-free InAIAs islands of ultrasmall dimensions embedded in
   AlGaAs have been grown by molecular beam epitaxy.  Cathodoluminescence was used to directly image the spatial distribution of the quantum dots by mapping their luminescence and to spectrally resolve very sharp peaks from small groups of dots, thus providing experimental verification for the discrete density of states in a zero-dimensional quantum structure.  Visible luminescence is produced by different nominal compositions of InxAl(1-x)As-AlyGa(1-y)As

 9 Design and Application of  Electron-Transporting Organic Materials 
  -Operating lifetime is the main problem that complicated the use of polymeric light-emitting diodes (LEDs).  A class of electron transport (ET) polymers (polyaryl acrylate) and polyaryl ethers is reported in which moieties with high electron affinities are covalently attached to stable polymer backbones.  Devices based on poly(p-phenylenevinylene)PPV prepared with these materials exhibited a 30-fold improvement in stability and in one case, dramatically lower operating voltage relative to those having conventional ET layers.  The current-carrying cpacity of indium tin oxide PPV polymeric ET layer aluminum LEDs was also increased by a factor
of 30.  These improvements lead to an enhancement in power efficiency of nearly an order of magnitude.  Choosing polymers with high glass transition temperatures increases deivce lifetime.
