Power-Efficiency Constraint for Chemical Motors
The mechanical movement driven by chemical gradients provides the primordial energy for biological functions. Its thermodynamic properties remains inclusive, especially for a dynamical change of energy demand in biological systems. In this article, we obtain a constraint relation between the changin...

| description | The mechanical movement driven by chemical gradients provides the primordial
energy for biological functions. Its thermodynamic properties remains
inclusive, especially for a dynamical change of energy demand in biological
systems. In this article, we obtain a constraint relation between the changing
output power and the conversion efficiency for a chemically fuelled rotary
motor analogous to the $\mathrm{F}_{0}$-motor of ATPase. We find the efficiency
at maximum power is half of the maximum quasi-static efficiency. These findings
shall aid in the understanding of natural chemical engines and inspire the
manual design and control of chemically fuelled microscale engines. |
