TL;DR: Experimental SFG data and molecular dynamics simulations demonstrate that ice-active sites within P. syringae feature unique hydrophilic-hydrophobic patterns to enhance ice nucleation, and the freezing transition is facilitated by the highly effective removal of latent heat from the nucleation site, as apparent from time-resolved SFG spectroscopy.

TL;DR: The combined use of SFG and ssNMR provides a more complete and quantitative picture of the structure, orientation, and dynamics of these surface-adsorbed peptides than could be obtained if either technique were used separately.

TL;DR: Strong linear dichroism related to the amide pi* orbital at 400.8 eV was observed in the nitrogen K-edge NEXAFS spectra for the adsorbed beta-strand peptides, suggesting that the peptide backbones are oriented parallel to the SAM surface with the side chains pointing toward or away from the interface.

TL;DR: Examination of the order of hydroxyl- and methyl-terminated phosphonate films deposited onto silicon oxide surfaces by the tethering by aggregation and growth method using complementary, state-of-art surface characterization tools shows that molecular order exists in the octadecylphosphonic acid and 11-hydroxyundecylph phosphonic acid SAMs.

TL;DR: From this multi-technique investigation it is clear that the majority of the oxygen detected within these amine-terminated SAMs arises from the presence of oxygen containing adsorbates such as tightly bound water.
