Long lived states induced by extended illumination of carbonmonoxy-myoglobin
… of magnitude in time. The bound and unbound states of the system have different spectroscopic signatures and the kinetics of recombination can be measured by monitoring the time dependence of the absorption spectrum of the sample after photodissociation. After a period of intense illumination …

Structural Basis of the Tensile Strength of Protein Complexes Mediating Cell Adhesion
… was used to characterize the multiple bound states between C-cadherin ectodomains. The experiments showed two short-lived bound states associated with the two outermost ectodomains and two long-lived states associated with the full ectodomain. It is likely that the two short-lived states are …

Broken ergodicity in myoglobin
"Biomolecules need long-lived far from equilibrium states to function. These states have a high Gibbs free energy that is used for biologically important functions such as catalysis and they need to live for a sufficiently long time, comparable to reactant diffusion times that vary from 100 ns on …

Preserving hyperpolarised nuclear spin order to study cancer metabolism
… exponential decay of the polarisation with the longitudinal relaxation time constant T1. This work aimed to improve the combination of hyperpolarisation and metabolic NMR/ MRI by extending the observation timescale of the technique. Working with quantum mechanical properties of the detected …

Charge and energy transport in 0D/2D systems probed using linear and nonlinear spectroscopy
… MoS₂. We show that deeply trapped "dark" exciton states are responsible for the surprisingly long lifetime of band-edge photoluminescence in acid-treated single-layer MoS₂ . Temperature-dependent transient photoluminescence spectroscopy reveals an exponential tail of long-lived states extending …

Making Nuclear Magnetic Hyperpolarization Practical through Storage in Disconnected Eigenstates
… relaxation time, T1. Disconnected eigenstates provide a mechanism by which hyperpolarization can be stored for several times T1. This thesis contributes to the knowledge of these states in four important ways. First, the decay of hyperpolarized magnetization of gas is simulated in lung …
