Electrode-assisted catalytic water oxidation by a flavin derivative

Abstract: The success of solar fuel technology relies on the development of efficient catalysts that can oxidize or reduce water. All molecular water-oxidation catalysts reported thus far are transition-metal complexes, however, here we report catalytic water oxidation to give oxygen by a fully organic compound, the N(5)-ethylflavinium ion, Et-Fl(+). Evolution of oxygen was detected during bulk electrolysis of aqueous Et-Fl(+) solutions at several potentials above +1.9 V versus normal hydrogen electrode. The catalysis was found to occur on glassy carbon and platinum working electrodes, but no catalysis was observed on fluoride-doped tin-oxide electrodes. Based on spectroelectrochemical results and preliminary calculations with density functional theory, one possible mechanistic route is proposed in which the oxygen evolution occurs from a peroxide intermediate formed between the oxidized flavin pseudobase and the oxidized carbon electrode. These findings offer an organic alternative to the traditional water-oxidation catalysts based on transition metals.

Negative and Positive Caregiving Experiences: A Closer Look at the Intersection of Gender and Relationship

Abstract: Using data from the 2004 wave of the National Long-Term Care Survey, we examined how negative and positive caregiving experiences differ by caregivers' gender and relationship to care recipients. We further considered how their caregiving experiences are affected by caregivers' demographic characteristics, care recipients' problem behavior and dependency, caregivers' involvement, reciprocal help from care recipients, and social support available for caregivers. We found that female and adult-child caregivers, in general, reported having had more negative experiences than male and spouse caregivers, respectively. Wife caregivers were least likely to report positive experiences. We also found different risk factors for negative and positive caregiving experiences, and these factors varied depending on caregivers' gender and relationship to the care recipient. The findings underscore the heterogeneity of caregiving experiences. To sustain informal care, state and local agencies need to tailor services to wife, husband, daughter, and son caregivers' unique needs.
