6 FAQs about [Ratchet energy storage]
What is an energy Ratchet?
In a chemical context this mechanism is generally referred to as an ‘energy ratchet’ 3a, 3l, 25 (alternatively termed a ‘flashing ratchet’ or ‘fluctuating potential ratchet’ in the physics literature 10).
Are energy ratchets spatially separated?
It appears that this sort of spatial separation of conditions in an energy ratchet has previously been employed without being recognised as such, for example in the voltage-driven deracemisation of a cage complex. 76 Further examples of systems that may involve such ratchet mechanisms are considered in Section 6.
Can energy ratchet mechanisms accelerate structure formation?
It appears to us that this mechanism has parallels with rate accelerations caused by ‘catalytic resonance’ (see Section 6.3.6), implying that energy ratchet mechanisms could also be applied to accelerate structure formation of other materials, such as colloids, 147b or select for specific crystalline assemblies. 147c
What is information ratchet mechanism?
Such ratchet mechanisms enable a catalyst to harness the energy released from the catalysed reaction to perform work. 2, 25 Synthetic molecular systems that operate through information ratchet mechanisms (using either light or chemical fuelling) are also increasingly being developed. 2, 3l
How do chemically fuelled information ratchets work?
Chemically fuelled information ratchets universally act as catalysts for the dissipation of a potential energy gradient in a fuel-to-waste process. 2, 4 As their reactivity is based on catalytic cycles, microscopic reversibility restricts how various parameters influence ratchet behaviour.
How does the energy Ratchet mechanism adapt the starting-material–product distribution?
The nonequilibrium distribution achieved by the energy ratchet mechanism stores ~0.6 kJ mol −1 after one cycle of carbodiimide fuelling and ~1 kJ mol −1 after a second cycle, illustrating adaptation of the starting-material–product distribution through progressivity of ratcheting cycles.
