Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
The 0D Cu-HHTP electrode shows a higher transient photocurrent response than the 1D and 2D morphology electrodes.
Caveat: Photocurrent magnitudes are visual estimates from Fig. 4d; no tabulated numerical photocurrent values were found.

The 0D morphology gives the highest BET surface area, gravimetric capacitance and ECSA among the three Cu-HHTP morphologies.
Caveat: 1D and 2D capacitance values were read approximately from the figure; exact ECSA values are text-reported.

The 0D spherical Cu-HHTP morphology improves pellet conductivity relative to 1D rod and 2D sheet powders.
Caveat: Transport comparison is on pressed powder pellets, so pellet packing and interparticle contacts are part of the measured behaviour.

Changing the water/DMF solvent composition switches Cu-HHTP particle morphology from 1D rods in 100% DMF to 2D sheets in 60% H2O/40% DMF.
Caveat: The statement applies to the microwave route and the concentrations/conditions reported in this paper.

Temperature-controlled ultrasonication creates dispersed seed clusters, and subsequent microwave growth yields 0D spherical Cu-HHTP.
Caveat: Mechanistic inference is based on SEM time evolution, Tyndall effect and fragment observations, not in situ structural measurements.

The authors attribute the high 0D powder conductivity to isotropic electron transport between spherical particles formed from radially arranged 1D rods.
Caveat: The isotropic transport picture is mechanistic interpretation supported by morphology and comparative transport; it is not a direct tensor conductivity measurement.
