Faraday Discussions are a unique conference format that priorities discussion. At a Faraday Discussion, the primary research papers written by the speakers are distributed to all participants before the meeting – ensuring that most of the meeting is devoted to discussing the latest research.
This provides a genuinely collaborative environment, where discussion and debate are at the foreground. All delegates, not just speakers, are invited to make comments, ask questions, or present complementary or contradictory measurements and calculations.
See Useful Links for more information about this conference and about Faraday Discussions.

Themes
Dynamics and Nano-Rheology of Interfacial Water
While we have made progress in understanding the static properties of interfacial water, water is in motion for many naturally occurring phenomena (raindrops falling, rivers flowing, etc.) and technological applications (water traversing membranes in water purification, desalination). At the nanoscale, the description of water in terms of its macroscopic properties (density, viscosity, etc.) breaks down, and novel concepts and experimental approaches are needed to further our understanding.
Electrified / Charged Aqueous Interfaces
Interfaces are often charged, because of the intrinsic charge of the material interface and membrane interface, as well as the emergence of the counter charge as a response of the water pH. In electrochemistry, charge is applied to drive molecular orientation, charge transfer, and chemical transformation. These interfaces induce ion condensation, generating the electrical double layer – Stern layer and diffuse layer Although it is evident that the molecular organization at electrochemical, electrified interfaces determines the chemistry occurring at these interfaces, the description of these processes still occurs at a mean-field level. Is that sufficient?
Ice Interfaces
Ice is omnipresent in the environment and constitutes an entirely different aqueous interface than that of the liquid. Or does it? The ice-vapor interface starts to be disordered – with reportedly liquid-like properties – above 200 K, much lower than the melting point of bulk ice. This disordered layer is often called the quasi-liquid layer. This quasi-liquid layer plays a critical role in the lubrication of ice surface, gas uptake by ice, and growth of aerosols affecting climate change. Furthermore, ice nucleation process such as heterogeneous ice nucleation which is bound to the material interface affects the biological functions of animals in the cold sea as well as technology aiming at controlling friction of ice.
Soft Matter-Water Interface
Soft matter ranges from the biological membrane interface to the polymer interface. Biological interfaces often are unstable without water; water drives the self-assembly of biological structures, and through the interaction with interfacial water, their biological function emerges. Polymer interfaces allow control over the hydrophobicity/hydrophilicity, and the variation of the interfacial water properties e.g. pH and temperature, alters the formation of polymers, making polymer materials useful for drug delivery and coating. A particularly interesting soft matter-water interface is the interface that originates from liquid-liquid phase separation in aqueous solutions of polymers and intrinsically disordered proteins. All these interfaces have in common that molecular-level insights into the interactions of these interfaces with interfacial water remain unclear.
