Abstract An active fluid denotes a viscoelastic suspension of particles, cells, or macromolecules able to convert chemical energy into mechanical work by generating stresses on the microscale. Some active particles may produce smart materials (biopolymers) under the presence of CO2 and CH4. Biopolymers of bacterial origin, with their vast range of applications, biodegradability and eco- friendly manufacturing processes, are one of the alternatives for a more sustainable future. However, the cost of their production is a drawback. The main goal of this Post-Doctorate project is to study the rheology of these complex suspensions of microorganisms. In this project, three aspects of the problem will be studied: first, the fundamental physical processes involved in the flow of these active fluids. Second, the experiments to understand how the variables related to the constitutive models of the suspensions may enhance the efficiency of biopolymer production. Third, the study of active particle migration when different composites and substrates are added in order to enhance CO2 and CH4 absorption. | |
