Research is being conducted on the development of phase change foams for thermal energy storage, with a focus on stabilization using cellulose nanofibrils and nanocrystals. The use of Pickering emulsion templating is being explored in this context, as well as in other applications such as environmental remediation and materials synthesis. The field appears to be broad, with various studies investigating different aspects of porous materials, nanocomposites, and sustainable biomass foams.
