The discussion centers around the use of sodium hydroxide (NaOH) in creating nanocontainers from lignin, specifically for encapsulating silica. One participant speculates about the potential application in producing paper cups, while another clarifies their intent to use lignin as a container for silica, with NaOH facilitating the encapsulation process. However, the conversation reveals a lack of expertise on the specific method for achieving this. The only known application of lignin and NaOH together mentioned is in paper-making. Overall, the participants express curiosity but ultimately find themselves unable to provide concrete assistance on the topic.
