Paper published in Applied Physics Letters

Our paper,  “Ultra-low thermal conductivity of ellipsoidal TiO2 nanoparticle films ”  was recently published in Applied Physics Letters (Applied Physics Letters 99, 133106 (2011)).  In this work, we show that films comprised of close-packed titania nanoparticles exhibit thermal conductivities that are lower than the theoretical minimum limit and show a dependency on nanoparticle orientation and alignment.
