Giant Nernst effect and bipolarity in the quasi-one-dimensional metal Li0.9Mo6O17.
TL;DR: The Nernst coefficient for the quasi-one-dimensional metal, Li{0.9}Mo{6}O{17}, is found to be among the largest known for metals, and is enhanced in a broad range of temperature by orders of magnitude over the value expected from Boltzmann theory for carrier diffusion.

Specific heat and thermal conductivity measurements for anisotropic and random macroscopic composites of cobalt nanowires.
TL;DR: The thermal conductivity for random composites (κ(R) follows a bulk-like behavior though it is greatly reduced in magnitude, exhibiting a broad maximum near 365 K indicating the onset of boundary-phonon scattering, and the specific heat measured with the heat flow parallel to the Co NW alignment is significantly reduced.
