By contrast, Uda et al.49 showed using ATR-FTIR spectroscopy that the AFGP molecules adsorbed on the ice water interface undergo a conformational change from a flexible extended helix to an α-helix.
Based on a previous study, where we showed using DFT calculations and hard XAS that Ti is in its Ti4+ state in LN209, we conclude that Ti in LNF15 remains as Ti4+ throughout cycling.
Lalli & Asthagiri showed, using densely-packed 2D cultures of mammary epithelial cells, that collective migration was more sensitive to dcEF (responding to 50% weaker fields than dispersed cells), yet the resulting electrotactic alignment occurred with slower dynamics29.
This study showed, using MD simulations, that a free-standing nanoporous graphene membrane can provide a higher salt rejection, but lower water permeability as compared to frozen membrane.
