Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
Carbon incorporation improves electrode stability under chronopotentiometry compared with carbon-free PS-CuO NDs.
Caveat: Potential drift for HS-CuO/C and PS-CuO/C is described qualitatively rather than tabulated numerically.

The hollow CuO/C shell gives HS-CuO/C NDs larger electrochemically active surface area and better OER activity than porous-shell CuO/C controls.
Caveat: ECSA is inferred from double-layer capacitance rather than independently measured geometric active-site density.

An inner Cu2O/CuO passive layer underneath the CuO/C hollow shell stabilises HS-CuO/C NDs during alkaline OER.
Caveat: The stabilising role is argued from post-test preservation and SAED phase assignment; no controlled removal of the passive layer is shown.
p003-p004 / 23809-23810 · Results and Discussion · Figure S7 · Linked to 2 structured results
A HKUST-1 Cu-MOF layer grown on Cu/Cu2O nanodendrites decomposes during Ar treatment and air calcination to form a nanostructured CuO/C hollow shell.
Caveat: The transformation mechanism is inferred from phase/composition and thermal route rather than in situ thermal monitoring.
p002 / 23808 · Introduction · Scheme 1 · Linked to 4 structured results
The highly conductive Cu core and carbon incorporation lower charge-transfer resistance and improve OER kinetics relative to carbon-free CuO controls.
Caveat: No direct four-probe/bulk electronic conductivity measurement is reported; the transport claim is supported by EIS and electrochemical performance.
