Open a family to keep every result attached to its sample, method and conditions.
Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
The Ni-CAT NWAs/CNF actuator combines large displacement, high strain, broad frequency response, high transduction efficiency and long cycling life in air.
Caveat: Device metrics are first-hand, but long-term cycling degradation is described qualitatively as negligible.

Ni-CAT nanowire arrays are successfully grown on CNF to form a core-shell Ni-CAT NWAs/CNF composite electrode.
Caveat: Single-paper assignment; no raw diffraction data available beyond figures/text.
p003 / article p.4019 · Synthesis and Characterization · Figures 1-2 · Linked to 4 structured results
Directly grown oriented Ni-CAT NWAs on CNF reduce ion/electron transport resistance relative to Ni-CAT powder.
Caveat: Comparison is based on equivalent-circuit interpretation of EIS.
p004 / article p.4020 · Electrochemical performance · Figure 3d · Linked to 4 structured results
The electrode capacitance includes EDLC behaviour, while actuator deformation is attributed to synergistic EDLC and redox pseudocapacitance-driven volume variation.
Caveat: Mechanistic assignment is inferred from CV shape/redox features and actuator response, not direct in situ ion imaging.
