Title: *Water Transformations in Nanoscale Environments*

Abstract:

Extreme confinement may drastically affect the physical and chemical 
properties of water and its solutions. We will examine in this talk two 
fundamental problems related to this question. The first one is the 
equilibrium constant for water dissociation. Different studies have 
suggested it may change by orders of magnitude in confinement, either 
toward larger or lower values. The second problem deals with gas 
generation in aqueous electrochemistry. Bubble formation, common to many 
electrochemical transformations, has as a drawback the blockage of the 
electrodes and the drop of the currents. Nanoelectrodes have been 
regarded as way to bypass this limitation, but the experimental 
dependence of the current with respect to electrode size and potential 
remained ambiguous. In this talk we present results from molecular 
simulations at different scales that answer these questions.
