2D Water in Clay Nanoconfinement: Tiny Space for Large Implications — •Vasily Artemov — Hamburg University of Technology

This talk presents recent advances in understanding the behavior of two-dimensional water in clay nanoconfinement, with a focus on its dielectric properties. Although clays are abundant, their crystal particles typically lack directional alignment. I will discuss an approach for self-assembling clay particles into large, scalable membranes in which the flakes are oriented parallel to each other, enabling a controlled and reproducible platform for studies of confined water at the nanoscale. Using this self-assembled nanofluidic platform, I will present experimental evidence of confinement-induced charge-separation effects that support electricity storage in water channels of 1 nm wide [1]. By combining insights from nanoscale physics, electrochemistry, and materials science, I will highlight how confinement within clay interlayers can influence ion transport, energy-storage phenomena, and our broader understanding of water at the interfaces.
