The molecular weight was calculated from an average of four titrations and was used for calculating the reaction stoichiometry of the subsequent PSU syntheses. 2.2.2. Size-Exclusion Chromatography Size-exclusion chromatography (SEC) studies were performed on a 1260 Infinity II GPC-SEC analysis system...
DFT calculations based on first-principles confirmed that the co-doping of the N and P atoms can improve the conductivity of carbon materials and the adsorption capacity of the Sodium-ions, as well as reducing the diffusion barrier of Sodium-ions between graphite layers. The research team also ...
Moreover, nitrogen-doping N-SHC material also exhibits superior cycling long-term stability, where the N-SHC electrode maintains a high reversible capacity at 200 mAh g−1 with a capacity retention of 81% after 600 cycles. DFT calculations assessed the change of K ions’ absorption energy ...

Power titration measurements are generally conducted to evaluate the optimal pump laser power to linearly excite the sample. When the magnitude of the difference scattering signal increases linearly with laser fluence, the sample remains in the linear photoexcitation regime, not subject to multiphoton eff...
