“…The long-lived T(1) state of the energy-donating ligands promoted an efficient thermally-assisted photosensitized emission of the Tb(III) acceptor ((5)D(4) level), resulting in a pure-green colored emission with a high photosensitized emission quantum yield (73%).…”

“…Results. 350 participants, having a mean age of 21.47 ± 1.36, were included in our study with 30.6% (107/350) being males and 69.4% (243/350) being females. 93.4% (327/350) of participants agreed that donating blood was healthy, but only 26% had donated blood in the past with 79.1% donating voluntarily. 65.7% (230/350) of the participants agreed to take part in Short Message Service based behavioral interventions to become voluntary blood donors with 69.7% (244/350) also agreeing that Short Message Service reminders will promote them to donate blood more often. …”

“…In this study, we demonstrate anti-platelet activity of nitrite at doses achievable through dietary interventions with comparison to similar doses with other NO donating agents. Unlike other NO donating agents, nitrite activity is shown to be potentiated in the presence of red blood cells in hypoxic conditions. …”

“…Our results suggest that depending on the orientation of the OH group with respect to the quinoline aromatic ring system, the presence of the formate molecule in a proton relay pathway facilitates a net proton transfer from the proton-donating OH group of 7HQ-N* via the methanol/formate bridge toward the quinoline N site.…”

Electron withdrawing groups were found to impact solvation free energy, transition dipole moment, static dipole difference, and absorbance more than electron donating groups. …”

“…Specifically, TDDFT calculations of the electron density difference between the S(1) excited state and S(0) ground state of PXX allowed us to identify the subtleties in the role of sites i.e., electron donating or withdrawing character on excitation. The replacement of two C(sp(2))-atoms with two N-atoms, in either electron donating or withdrawing positions, shifts the electronic transitions either to low or high energy, respectively. …”
