Modulation of hydrophobic effect by cosolutes

Article Abstract:

A comparison of the hydration properties and self-association behavior in aqueous solution of three biologically relevant simple molecules that include tert-butyl alcohol (TBA), trimethylamine-n-oxide (TMAO), and glycine betaine (GB) is conducted to study hydrophobic behavior in water solution. Results indicate that, while TBA starts to self-aggregate at approximately X2 = 0.025, both TMAO and GB do no exhibit any significant self-aggregation up to the highest concentration considered.

Microviscosity in multiple regions of complex aqueous solution of poly(ethylene oxide)-poly(propylene oxide)-poly-(ethylene oxide)

Article Abstract:

A study is performed to investigate the microviscosity in multiple regions of complex solutions if poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide) by comparing the rotational correlations obtained for the coumarins having considerably different hydrophobic properties. The investigation fluorescence anisotropies do not show any correlations with the microphase transition to form cubic hydrogels.
