Excitation energy transfer between closely spaced multichromophoric systems: Effects of band mixing and intraband relaxation [PDF]

open access: yes, 2006
We theoretically analyze the excitation energy transfer between two closely spaced linear molecular J-aggregates, whose excited states are Frenkel excitons.

Dipole-dipole interaction between a quantum dot and graphene nanodisk [PDF]

open access: yes, 2012
We study theoretically the dipole-dipole interaction and energy transfer in a hybrid system consisting of a quantum dot and graphene nanodisk embedded in a nonlinear photonic crystal.

Optically controlled resonance energy transfer:Mechanism and configuration for all-optical switching [PDF]

open access: yes, 2008
In a molecular system of energy donors and acceptors, resonance energy transfer is the primary mechanism by means of which electronic energy is redistributed between molecules, following the excitation of a donor. Given a suitable geometric configuration

Calcium and energy transfer

open access: yesThe Journal of Physiology, 2005
A recent article in The Journal of Physiology by Gueguen et al. (2005) shows that an efficient metabolic coupling between mitochondrial creatine kinase (mtCK) or adenylate kinase (AK2), and ADP rephosphorylation via mitochondrial respiration is tissue specific: it is functioning in skinned muscle of oxidative type I and type IIa but not in IIx type ...

Energy transfer in molecular devices [PDF]

open access: yesPhysical Review E, 2014
Protein machines often exhibit long range interplay between different sites in order to achieve their biological tasks. We investigate and characterize the non--linear energy localization and the basic mechanisms of energy transfer in protein devices.

Study on the Characteristics of Expander Power Output Used for Offsetting Pumping Work Consumption in Organic Rankine Cycles

open access: yesEnergies, 2014
The circulation pump in an organic Rankine cycle (ORC) increases the pressure of the liquid working fluid from low condensing pressure to high evaporating pressure, and the expander utilizes the pressure difference to generate work.

Förster energy transfer between neighbouring chromophores in C-phycocyanin trimers [PDF]

open access: yes, 1993
The excitation-energy transfer in C-phycocyanin (C-PC) trimers and monomers isolated from phycobilisomes of Mastigocladus laminosus has been studied by polarization femtosecond laser spectroscopy. Excitation with 70-fs pulses at 615 nm gave rise to a 500-

Dexter energy transfer pathways [PDF]

open access: yesProceedings of the National Academy of Sciences, 2016
Significance Controlling the dynamics of excitons—including their transport, fission, fusion, and free carrier generation—presents a central challenge in energy science, optoelectronics, and photobiology. We develop a coupling-pathway theory for triplet energy transfer, a process controlled by the structure of the medium between donor and ...
