This paper describes theoretical calculations of the combined effect of bulk and interfacial rheological properties on dissolution behavior of a bubble in an infinite medium at saturated conditions. Either bulk or interfacial elasticity can stop the bubble dissolution process, and stability criteria are defined for the elastic cases. In the case of an elastic interface with dilation modulus E(d) and a bubble with an initial radius R(0) and initial interfacial tension sigma(0), the bubble is stabilized as it has shrunk to a relative radius of varepsilon=R/R(0)=exp(-sigma(0)/2E(d))). In case of an elastic bulk with modulus G a bubble will shrink until GR(0)=4sigma(0)varepsilon(3)/(1-5varepsilon(4)+4varepsilon(3)) is fulfilled. Bulk and interfacial viscosity can retard the dissolution process if their magnitude exceeds a certain critical value but will never completely stop bubble dissolution. Copyright 2001 Academic Press.

Silicon-based all-solid-state batteries offer high energy density and safety but face significant application challenges due to the requirement of high external pressure. In this study, a LiSi/Si-LiSi double-layered anode is developed for all-solid-state batteries operating free from external pressure. Under the cold-pressed sintering of LiSi alloys, the anode forms a top layer (LiSi layer) with mixed ionic/electronic conduction and a bottom layer (Si-LiSi layer) containing a three-dimensional continuous conductive network.

The standard Poisson-Boltzmann (PB) model for molecular electrostatics assumes a sharp variation of the permittivity and salt concentration along the solute-solvent interface. The discontinuous field parameters are not only difficult numerically, but also are not a realistic physical picture, as it forces the dielectric constant and ionic strength of bulk in the near-solute region. An alternative to alleviate some of these issues is to represent the molecular surface as a diffuse interface, however, this also presents challenges.
