| Abstract Scope |
Architected materials can be used to elicit and direct fluid flow with the ability to control multiphase interfaces [1]. If the characteristic length scale of unit cells comprising a lattice is small (below 1-2 mm), the distribution of a liquid through that lattice is dominated by surface tension effects. Thus, architected porous media can be designed and manufactured to leverage capillary flow and gas-liquid interfaces in three dimensions. We discuss design considerations for such materials and illustrate examples of applications, such as fabrication of novel electrochemical devices, structured composite materials, CO2 absorbers, and electrospray ionization. *** This work performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344 within the LDRD program 22-ERD-029.
