‘One of the most striking developments in work on science and religion in recent years has been the increasing focus, not just on how science and religion relate to each other, but on how they each contribute to human flourishing. Briggs and Reiss have provided an excellent and much-needed conceptual framework for understanding “human flourishing”, and how scientific developments and spiritual wisdom contribute to it. They take us through the different dimensions of human flourishing (material, relational and transcendent); the pillars of human flourishing (truth, meaning, and purpose), and discuss how all this is working itself out in different aspects of the contemporary world. Their writing is accessible and gripping, full of striking anecdotes and pithy summaries of scientific research.’ (Professor Fraser Watts, Executive Secretary of the International Society for Science and Religion)

The outcome of an electron-transfer process is determined by the quantum-mechanical interplay between electronic and vibrational degrees of freedom.

Nonequilibrium vibrational dynamics are known to direct electron-transfer mechanisms in molecular systems; however the structural features of a molecule that lead to certain modes being pushed out of equilibrium are not well understood.

Herein, we report on electron transport through a porphyrin dimer molecule, weakly coupled to graphene electrodes, that displays sequential tunneling within the Coulomb-blockade regime.

The sequential transport is initiated by current-induced phonon absorption and proceeds by rapid sequential transport via a nonequilibrium vibrational distribution of low-energy modes, likely related to torsional molecular motions.

We demonstrate that this is an experimental signature of slow vibrational dissipation and obtain a lower bound for the vibrational relaxation time of 8 ns, a value dependent on the molecular charge state.
