Hydroxypropyl cellulose (HPC) is a widely commercialized derivative. While it typically used as binder or stabilizer for foods and pharmaceuticals, can also form cholesteric liquid crystal in aqueous solution. Moreover, at high HPC concentrations this lyotropic thermotropic mesophase known to reflect structural color. However, remains challenge retain vibrant coloration into the solid state. He...

Low-viscosity, aqueous solutions of hydrophilic linear polymers have been shown to be useful for the separation of DNA restriction fragments by capillary electrophoresis (CE). However, the choice of polymer type, size, and concentration remains largely empirical, because the mechanism of high-field electrophoretic DNA separations in polymer solutions is not well understood. To assist in elucida...

Phase separation of thermo-responsive polymers in solution is a complex process, whose understanding is essential to screen and design materials with diverse technological applications. Here we report on a method based on dynamic light scattering (DLS) experiments to investigate the phase separation of thermo-responsive polymer solutions and precisely define the transition temperature (TPS). Ou...

A new class of cyclometalated ruthenium complexes, Ru(C^N^N')(N^N'^N'')·Cl where N^N'^N'' = 4,4',4''-tricarboxy-2,2':6',2''-terpyridine and C^N^N' = substituted 6-phenyl-2,2'-bipyridine, for Dye Sensitized Solar Cells (DSSCs) is proposed. We have investigated the effect of different substituents (R = COOH, thiophen-2-yl, F and OCH(3)) on the ancillary C^N^N' ligand on the photophysical properti...
