    “…The model is used to study how the partially charged AIP and polarizable ASP lead to intriguing double-layer capacitance curves that are different from what the conventional Gouy–Chapman–Stern model describes. The model provides an alternative interpretation for recent capacitance data of Pt(111)–aqueous solution interfaces calculated from cyclic voltammetry. …”

    “…With the aim of critically assessing all three claims, we analyze data collected through observations of and interviews with expert players of the avatar-based video game League of Legends. Focusing on Daniel Stern’s (2010) notion of vitality, we analyze the participants’ descriptions of seeing and interacting with other avatars during performance. …”

    “…Due to the novel S(2–) ion-induced structural transformation, we found that the amorphous Eu(3+)-doped zinc/silicate phosphors demonstrate a C(LOD) sensitivity as low as 1.8 × 10(–7) M and a high Stern–Volmer constant (K(SV)) of 3.1 × 10(4) M(–1). …”

    “…These effects on channel gating are consistent with a reduction in negative surface potential due to titration of negative external surface charge. The Gouy-Chapman-Stern surface charge model incorporating specific proton binding provides an excellent fit to the dose-response curve for the shift in the midpoint of the h infinity curve with protons, yielding an estimate for total negative surface charge density of -1e/490 A2 and a pKH for proton binding of 5.16. …”

    “…The formation of naringin palmitate-BSA was revealed by fluorescence quenching, and the Stern-Volmer quenching constant (K(SV)) was found to decrease with increasing temperature, suggesting that a static quenching mechanism was involved. …”

    “…The choice of electrolyte is also critically important because the reaction rate is dependent on the counterion type, suggesting a role in enhancing the electric field at the sharp spikes and increasing N(2) concentration within the Stern layer. The energy efficiency of the reaction is estimated to be 5.25% at the current FE of 11.56%.…”

    “…Also, the detailed mechanistic investigation for their mode of action through spectral overlap, lifetime measurements, Stern–Volmer plots, and density functional theory calculations reveals that resonance energy transfer and photoinduced electron transfer processes, and electrostatic interactions are the key aspects for the turn-off response toward TNP by 1 and 2. …”

The acid/base equilibrium of RHG between its protonated open form (o-RHG) and deprotonated closed spiro-form (c-RHG) at the membrane interface was monitored with UV-vis absorption and fluorescence spectra. …”
