Breaking the Air-Water Paradigm: Ion Behavior at Hydrophobic Solid-Water Interfaces
Xavier R. Advincula, Kara D. Fong, Yongkang Wang +4
Hydrophobic solid-water interfaces underpin processes in nanofluidics, electrochemistry, and energy technologies. Microscopic insights into these systems are often inferred from ou…
Wetting Transparency of Graphene: A macroscopic Window but Nanoscopic Mirror
Yongkang Wang, Yair Litman, Minhaeng Cho +2
Graphene supported on a substrate in contact with water underpins a wide range of processes and technologies, yet its wettability remains controversial. Understanding how substrate…
On the Slipperiness of Surfactants: Charge-Mediated Friction Control at the Molecular Scale
Kaili Xie, Julie Jagielka, Liang Peng +8
From soap-covered dishes to freshly cleaned floors, surfactants can make surfaces slippery; yet, the underlying mechanism remains poorly understood. Here, we identify the molecular…
Spontaneous Surface Charging and Janus Nature of the Hexagonal Boron Nitride-Water Interface
Yongkang Wang, Haojian Luo, Xavier R. Advincula +14
Boron, nitrogen and carbon are neighbors in the periodic table and can form strikingly similar twin structures-hexagonal boron nitride (hBN) and graphene-yet nanofluidic experiment…
Interfaces Govern Structure of Angstrom-scale Confined Water
Yongkang Wang, Fujie Tang, Xiaoqing Yu +6
Water plays a crucial role in geological, biological, and technological processes. Nanoscale water confinement occurs in many of these settings, including sedimentary rocks, water…
