Sapphire Stars in Nanotube Support Role

On crystal surfaces, nanotubes self-guide themselves into dense structures with exciting potential applications as sensors or integrated circuits

27-Apr-2005 - USC researchers have found that sapphire surfaces spontaneously arrange carbon nanotubes into useful patterns - but only the right surfaces. Nanotubes are one-atom thick sheets of carbon rolled into seamless cylinders. They can be used to work as chemical sensors and transistors, like devices ...

Scientists Grow Thermoelectric Cobaltate Thin Films on Silicon

10-Mar-2005 - Thin films made of so-called thermoelectric materials could be used to convert heat directly into electric energy, or vise versa, for a variety of applications, including micro-chip-based chemical and biological sensors and more-efficient ways to cool computer chips. Thermoelectrics also hold ...

Playing with Light and Color

Assemblies of blue-green iridium and red europium complexes undergo energy transfer and emit white light

26-Jan-2005 - Complexes of the rare earth element (lanthanide) europium have the ability to emit red light over a longer time span after excitation by, for example, light of a suitable wavelength or the energy of a prior redox reaction. This luminescence makes them interesting candidates for applications ...
