Abstract Crack defects produced during the operation of proton exchange membrane fuel cells (PEMFCs) have a significant impact on their service life. One common approach to extend working time is embed self-healing microcapsules in repair defects. In this study, we use extended finite element method (XFEM) investigate capture and control cracks by doped numerically simulate crack propagation pa...

Cell-free synthetic biology emerges as a powerful and flexible enabling technology that can engineer biological parts and systems for life science applications without using living cells. It provides simpler and faster engineering solutions with an unprecedented freedom of design in an open environment than cell system. This review focuses on recent developments of cell-free synthetic biology o...

We develop a performance model for a polymer electrolyte membrane based regenerative hydrogen-bromine fuel cell (rHBFC). The model includes four voltage loss mechanisms: ohmic loss through the membrane, hydrogen electrode activation, bromine electrode activation, and bromine electrode mass transport. We explore a large parameter space by looking at the dependences of each of these losses as a f...

We present a novel optical methodology including both instrumentation and theory aimed at retrieving the full viscoelastic information of cell membrane material properties. Red blood cells (RBC) are chosen for this study because of their simple structure, which consists of a bi-layer cell membrane supported by a cytoskeleton enclosing a homogeneous fluid. The full complex modulus of RBC in term...
