Abstract: This application relates to a distributed software-defined network (“DSDN”) for dynamically configuring and managing a wireless communication network. A plurality of DSDN nodes are connected to each other via a plurality of communication paths. Each communication path directly connects two DSDN nodes.

Abstract: A method for producing carbon negative cementitious materials utilizing a carbon mineralization-based direct-air capture process. The method comprises a mineralization step wherein a mineral feedstock is contacted with an aqueous carbonate solution at a high initial pH to form a carbonated feedstock containing reactive silica, along with an alkaline solution containing dissolved aluminum. The resulting alkaline solution is then contacted with gaseous carbon dioxide to form a carbonate solution that can be recycled for use in the mineralization step. The dissolved aluminum in the alkaline solution precipitates during carbon dioxide capture and is subsequently redissolved in a hydroxide solution to form alumina. The alumina can be combined with the carbonated feedstock to create geopolymer concrete.
