Energy-Saving Strategies of Axial Flow Fans for Direct Dry Cooling System
Energies, 2021 The operating conditions of axial flow fans are closely related to the thermo-flow characteristics of the mechanical draft direct dry cooling system. Moreover, the uneven distribution of cooling air driven by axial flow fans may lead to the deterioration

Engineering directed excitonic energy transfer [PDF]
, 2010 We provide an intuitive platform for engineering exciton transfer dynamics. We show that careful consideration of the spectral density, which describes the system-bath interaction, leads to opportunities to engineer the transfer of an exciton.

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