The alpha-helical coiled-coil tropomyosin homodimer, alpha alphaTm, unfolds cooperatively with T1/2 = 47 degreesC, at neutral pH, 0.5 M NaCl. At pH 2, where each chain contains 55 positive charges, no cooperative unfolding occurs to at least 80 degreesC. The

Tungsten trioxide/bismuth vanadate heterojunction is one of the best pairs for solar water splitting, but its photocurrent densities are insufficient. Here we investigate the advantages of using helical nanostructures in photoelectrochemical solar water splitting. A helical tungsten trioxide array is
