Polycation Interactions with Zwitterionic Phospholipid Monolayers on Oil Nanodroplets Suspensions in Water (D2O) Probed by Sum Frequency Scattering

Sylvie Roke, Nikolay Smolentsev

By combining dynamic light scattering (DLS) measurements and infrared (IR) spectroscopy with the interface- and bond-specificity of vibrational sum frequency generation scattering (SFS) spectroscopy, we probe several structural aspects of how zwitterionic ...

Developing Reactions of Strained Rings : Enantioselective Desymmetrization of meso-Diaminocyclopropanes and Annulation of Donor-Acceptor Aminocyclobutanes

Daniele Perrotta

Carbo- and heterocyclic structures containing nitrogen-substituted stereocenters are recurrent structural motifs in natural and bioactive compounds, therefore constituting a privileged class of synthetic targets. In this regard, substituted three- and four ...

Beyond the Hofmeister Series: Ion-Specific Effects on Proteins and Their Biological Functions

Halil Ibrahim Okur

Ions differ in their ability to salt out proteins from solution as expressed in the lyotropic or Hofmeister series of cations and anions. Since its first formulation in 1888, this series has been invoked in a plethora of effects, going beyond the original ...
