Beschreibung
Water is a crucial element for life. However, there is still debate on why it is so important. This is because the mechanisms that control the effect of water on biological and nanoscopic solutes still need to be fully understood. Additionally, the challenges of renewable energy sources and water pollution are two major environmental concerns that need addressing: hydrated nano-interfaces could offer new solutions for applications such as desalination, decontamination, energy storage, and heterogeneous catalysis for green hydrogen production. This Colloquium will provide a broad introduction to these topics, connecting them with the unique properties of water [1, 2, 3]. Using Statistical Physics to create phenomenological models and multiscale computation can fill the knowledge gap and guide us toward new applications. For instance, it is possible to understand how hydration water modulates the folding, condensation, aggregation, and adsorption of proteins in solutions onto nanomaterials [4, 5]. This is a crucial element in designing new drugs or drug-delivery nanomedical devices. Another example is how this approach provides a way to explore the feasibility of using graphene nano-sponges and slit-pores for the physical filtration of water from pollutants [6, 7].
