Resonances in the cross-section, when seen as a function of neutron kinetic energy, could be understood by using the compound nucleus (CN) model of the reaction. The CN is left, on formation, in an energy level that depends on the energy brought in by the neutron, namely, the neutron-...
energy transfer is strongly dependent on the distance between the donor and the acceptor. Therefore, it serves, indirectly, to detectPPI. The exact distance at which FRET can occur depends on the donor/acceptor used, for those used to detect PPI this distance is less than 10 nm[67...
The consequence of the energy transfer on the performance of the overall efficiency of a model ZnO NP-based dye-sensitized solar cell (DSSC) has also been explored. We have demonstrated that the overall efficiency of a ZnO NP-based solar cell significantly depends on the presence of high-...
Forster resonance energy transfer (FRET) describes excitation energy exchange between two adjacent molecules typically in distances ranging from 2 to 10 nm. The process depends on dipole-dipole coupling of the molecules and its probability of occurrence cannot be proven directly. Mostly, fluorescence is...
Genetically encoded, Förster resonance energy transfer (FRET) biosensors enable live-cell optical imaging of signaling molecules. Small conformational changes often limit the dynamic range of biosensors that combine fluorescent proteins (FPs) and sensing domains into a single polypeptide. To address this...
This real-space view of delocalization can also describe the aromaticity of polycyclic aromatic compounds like pyrene (Fig.1), for which the Hückel rule is not valid. While the total number ofπelectrons is 16, there is still a plethora of possible rotations: e.g., on each six-membered ...
Although photons are neither emitted nor re-absorbed, the energetic considerations still hold. The probability forFRETrises with the overlap area of the two spectra – more energy wins through if the windows fit better. Also, the orientation of the molecules has an influence on the transfer ...

Therefore, net absorbance of energy depends on the difference in populations between the ground state and the excited state. Because the population ratio is determined by the appropriate Boltzmann expression (e−Δ/kT, where Δ is the energy difference between states and k is the Boltzm...
The Förster distance (R0) describes the physical distance between the two chromophores at which 50% of the maximal energy transfer occurs and it depends on the choice of RET components. R0 can be experimentally determined using flexible peptide linkers of known lengths to separate the two ...
