Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
Optimised Zn,Ni-CAT-T4 delivers high areal capacitance and long cycle retention for supercapacitor electrodes.
Caveat: Capacitance calculation details are presented mainly as plots; exact best values are text-reported, while curve-only values remain approximate unless digitised later.
9 · 4. Conclusion · Linked to 5 structured results
The Zn,Ni-CAT-T4 symmetric all-solid-state device maintains high capacitance, cycling stability and enough series voltage to light an LED.
Caveat: Device bending data are SI-only and reported qualitatively from the available rendered SI/text; no raw curve data were supplied.
9 · 3.4. Energy storage performance of Zn,Ni-CAT · Figure 7 · Linked to 3 structured results
Zn incorporation preserves the parent Ni-CAT framework while enlarging the lattice spacing and shifting the (100) XRD peak to lower angle.
Caveat: No CIF was supplied; assignment relies on XRD/HRTEM and the authors' phase interpretation.
6 · 3.3. Optimization of bimetallic MOFs by microwave · Figure 4c-d · Linked to 6 structured results
Vapour-phase microwave pulse discharge provides rapid and controllable introduction of bimetallic Zn into conductive Ni-CAT, with total reaction time as short as 20 s for the best T4 sample.
Caveat: ICP repeatability table bodies are available in the rendered SI; overlong 25 s and 60 s treatments are only described qualitatively for morphology damage.
1 · Abstract · Linked to 8 structured results
Microwave-absorbing carbon cloth prevents Zn nanoparticle film deposition and favours Zn incorporation into the conductive Ni-CAT lattice, whereas glass supports Zn nanoparticle deposition.
Caveat: Mechanism is inferred from control substrate behaviour and EDS; direct atomic pathway evidence is not shown.
5 · 3.2. Microwave synthesis mechanism · Figure 3 · Linked to 2 structured results
Bimetallic Zn/Ni nodes promote electronic coupling, reduce charge-transfer limitations and improve ion diffusion, contributing to higher capacitance and rate capability.
Caveat: The paper uses EIS and XPS shifts as transport proxies; no direct four-probe electronic conductivity of films is reported in the main text.
