Interfacial Water Responds Linearly to Charge yet Is Charge-Asymmetric
Yair Litman, Yongkang Wang, Stephen J. Cox +2
The organization of interfacial water shapes the electric double layer behavior in aqueous electrolytes. Asymmetries upon charge reversal are commonly attributed to specific ion ad…
How Good Is DFT for Solid-Liquid Interfaces? A Comparison With the Random-Phase Approximation for Water on Graphene
Xavier R. Advincula, Yair Litman, Jiuyang Shi +3
Simulations of water at solid interfaces routinely disagree on basic properties, from contact angle to friction, depending on the model used, whether an empirical force field or a…
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…
Reevaluating Anomalous Electric Fields at the Air-Water Interface: A Surface-Specific Spectroscopic Survey
