1. Composite cathodes consisting of LSM YSZ have been used to increase this triple phase boundary length. 2. Bubble column reactors are characterized by a high liquid content and a moderate phase boundary surface. 3. If multiple phases of matter are present, the chemical potentials across a phase boundary are equal. 4. In the diagram on the left, the phase boundary between liquid and gas does not continue indefinitely. 5. Such motion of a phase boundary , involving advancing and receding contact angles, is known as dynamic wetting. 6. Dislocations dissociate in the ?'- phase, leading to the formation of an anti-phase boundary . 7. This protein accumulates at the G1-S phase boundary and is degraded as cells progress through S phase. 8. Above the critical point and away from the phase boundary curve, and the temperature and pressure can be controlled independently. 9. The phase boundaries cause structural weakness in the resulting material, meaning that polymer blends are useful in only limited applications. 10. In addition, there is no surface tension in a supercritical fluid, as there is no liquid / gas phase boundary .
