The hydrophobic-water interface plays a key role in biological interactions. However, both the hydrophobic-water interfacial molecular structure and the origin of the negative zeta potential of hydrophobic droplets in water are heavily contested. We report ...

Liquid flow along a charged interface is commonly described by classical continuum theory, which represents the electric double layer by uniformly distributed point charges. The electrophoretic mobility of hydrophobic nanodroplets in water doubles in magni ...

The structures of interfaces of nano- and microscale objects in an aqueous solution are important for a wide variety of physical, chemical, and biological processes. Vibrational sum frequency (SF) scattering has emerged as a useful and unique probe of the ...

The unique properties of water are critical for life. Water molecules have been reported to hydrate cations and anions asymmetrically in bulk water, being a key element in the balance of biochemical interactions. We show here that this behavior extends to ...

Hydrophobic oil droplets, particles, and air bubbles can be dispersed in water as kinetically stabilized dispersions. It has been established since the 19th century that such objects harbor a negative electrostatic potential roughly twice larger than the t ...

Aqueous interfaces are responsible for a plethora of processes. At the nanoscale, interfaces are overwhelmingly influenced by finite volume effects that are thought to impact both molecular level and macroscopic properties. Here, finite volume effects are investigated using electrophoretic mobility and vibrational sum frequency scattering of water nanodroplets in oil and oil nanodroplets in water, made from the same chemicals. Notably, there is a substantial difference in the orientational ordering of water
