Metallic transport in polyaniline
Article Abstract:
A report of the classic metallic transport data obtained from truly metallic polymers is presented. With polyaniline samples prepared using self-stabilized dispersion polymerization, it is found that for samples having room-temperature conductivities in excess of 1,000 S cm(super -1), the resistivity decreases monotonically as the temperature is lowered down to 5K and the infrared spectra are characteristic of the conventional Drude model even at the lowest frequencies measured.

Structural mechanism for sterol sensing and transport by OSBP-related proteins
Article Abstract:
The structure of the full-length yeast oxysterol-binding-protein (OSBP)-related proteins (ORPs) Osh4 at 1.5-1.9 Angstrom resolution in complexes with ergosterol, cholesterol, and 7-, 20- and 25-hydroxycholesterol is reported. It is found that a single sterol molecule binds within a hydrophobic tunnel in a manner consistent with a transport function for ORPs.
