Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
Ag4TSHQ provides higher gravimetric capacitance and cycling retention than Ag4TTHQ under the tested three-electrode conditions.
Caveat: Electrode is a composite with PTFE/carbon black on carbon paper; discharge curve is described as suboptimal.
7 · Supercapacitor Performance of Ag4TXHQ Species · Figure 6c-e · Linked to 4 structured results
The authors note suboptimal discharge/capacitance retention and suggest improving crystallinity, electrolyte, potential window or metal ions.
7 · Supercapacitor Performance of Ag4TXHQ Species · Linked to 1 structured result
Pellet conductivity for the Ag4TXHQ series reflects inter-crystal transport and does not directly track intrinsic TRTS mobility or carrier density.
15 · Supporting figures and tables · Figure S10 · Linked to 2 structured results
Ag4TSHQ maintains the same structural topology as Ag4TTHQ after sulfur-to-selenium substitution.
Caveat: Ag4TSHQ model was constructed from Ag4TTHQ and refined against PXRD with restraints rather than solved ab initio from PXRD alone.
3-4 · X-ray Characterization and Crystal Structure Determination · Linked to 4 structured results
Mixed TTHQ/TSHQ ligand ratios tune the optical band gap from about 0.6 to 1.5 eV while retaining similar PXRD patterns.
Caveat: Several individual mixed-ligand gap values are read from figure labels rather than tabulated.
5 · Theoretical and Experimental Studies on the Bandgap Regulation through Atomic Change · Figure 4c · Linked to 5 structured results
Ag4TSHQ more effectively uses redox sites than Ag4TTHQ, with higher diffusion-controlled Faradaic contribution across scan rates.
Caveat: Capacitive contribution values are taken from stacked-bar figure labels.
6 · Supercapacitor Performance of Ag4TXHQ Species · Figure S15 · Linked to 4 structured results
Replacing sulfur with selenium increases short-range charge mobility by increasing scattering time and reducing backscattering.
Caveat: TRTS mobility assumes similar photon-to-free-carrier conversion ratios.
