Optimal energy dissipation in growing microorganisms and rectification columns

Urs von Stockar

This paper proposes a new point of view in analyzing the optimal Gibbs energy dissipation in growing microorganisms. Small Gibbs energy dissipation in growth would be of biological advantage because less resource is consumed and the biomass yield on these ...

Evaluation of advanced technologies based on integration techniques - Application on dividing wall column

Seifeldine Ahmed Fathalla

In order to separate a mixture into high purity products, Dividing Wall Distillation Columns (DWCs) have shown to be, in most cases, more convenient than using conventional distillation column sequence. In fact in DWCs the entire separation task occurs in ...

A unified framework for non-Brownian suspension flows and soft amorphous solids

Matthieu Wyart

While the rheology of non-Brownian suspensions in the dilute regime is well understood, their behavior in the dense limit remains mystifying. As the packing fraction of particles increases, particle motion becomes more collective, leading to a growing leng ...
