Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
Ni2DDA air cathodes improve photo-assisted Zn-air and Sn-air battery performance under light and elevated temperature up to 80 degC.
Caveat: Some round-trip efficiency values are internally inconsistent in the main text; conflicting text-reported values were retained separately.

Ni2DDA preserves electronic/valence structure at high temperature and shows thermal stability relevant to high-temperature photo-assisted batteries.

Ni2DDA is an electronically conductive pi-d conjugated Ni-MOF formed by Ni coordination to amino and hydroxyl sites of DDA.
Caveat: The main text contains a likely typo referring to Fe-O3-N monatomic sites in a Ni material.
p003-p004 · Results and Discussion · Figures 1-2 · Linked to 10 structured results
The narrow bandgap, p-type behaviour and photothermal response of Ni2DDA enable synergistic photoelectric/photothermal enhancement of OER and ORR kinetics.
Caveat: Photocurrent, ORR and several SI supporting plots are qualitative in the supplied text layer.
