We have used femtosecond midinfrared spectroscopy to study the orientational mobility of water molecules in the hydration shells of hydrophobic groups. Our results show that hydrophobic groups are surrounded by a number of water molecules that display much slower orientational

We study the influence of the amphipilic compound tetramethylurea (TMU) on the dynamical properties of water, using dielectric relaxation spectroscopy in the regime between 0.2 GHz and 2 THz. This technique is capable of resolving different water species, their relative

Piliated Burkholderia (formerly Pseudomonas) cepacia from sputa of cys tic fibrosis patients in Toronto, Canada, were shown earlier to bind to purified mucins and to a protein receptor on epithelial cells via a 22-kDa adhesin located on unique cable pili.

We have developed what we call the 1-propanol(1P) probing methodology. By using it, we determined the relative hydrophobicity/hydrophilicity indices of 2-butoxyethanol, a typical hydrophobe; urea, a typical hydrophile; and trimethylamine-N-oxide, an amphiphile. By comparing these indices with those for other
