We develop a statistical mechanical theory of charge storage in quasi-single-file ionophilic nanopores with pure room temperature ionic liquid cations and anions of different size. The theory is mapped to an extension of the Ising model exploited earlier for the case of cations and anions of the...
size also generally decreases because of the increased attraction between the nucleus and the outermost electrons. These properties influence the formation and also the characteristics of anions as an atom, molecule or within a compound. Generally, the anions have opposite properties when compared to t...
where the Ni-Fe oxyhydroxide (OOH) is among the most active catalysts for alkaline OER. Electrolyte alkali metal cations have been shown to modify the activity and reaction intermediates, however, the exact mechanism is at question due to unexplained deviations from the cation size trend...
As with anions, many of the real samples analysed have been various water samples, fruit juices and beverages and food. An example of an unusual application of CE to the analysis of high salinity samples is shown in Figure 10. Sign in to download full-size image Figure 10. Separation of...
Full size image For multiple-site anions, e.g. 1,2,3-triazolide (3), SO2 can interact with two unequal N sites (labelled as 1 and 2 in Fig. 1) to produce two stable structures in the presence of Li+ (ESI Fig. S4b). Interestingly, these two absorption products can also interconve...
As the total charge of the permeating cations in the membrane is equal to the charge carried by the present lipophilic anions, different cations will actually compete with each other to enter or to leave the SLM in the case of mixed-salt solutions in the feed phase. Fig. 4 shows how the...
Structure of (NpO2)4Cl4(H2O)7(1).aProjection of the three-dimensional network of cation−cation-bonded NpVO2+square nets, with open channels along the [0 0 1] direction. Chloride anions and water molecules that reside inside the channels are omitted for clarity.bLocal coordination environm...
The theory is mapped to an extension of the Ising model exploited earlier for the case of cations and anions of the same size. We calculate the differential capacitance and the stored energy density per unit surface area of the pore. Both show asymmetry in the dependence on electrode potential...
Full size image Discussion We have applied femtosecond broadband SFG-VS to investigate the molecular conformation of spacer organic cations in 2D OIHP films and established a correlation among the conformation of the organic cations, the charge-carrier mobility, and broadband emission. It is found th...
which are generally relatively large compared with simple inorganic cations, account for the low melting points of the salts. Anions range from simple inorganic anions to large complex anions. The synthesis process is environmentally friendly and does not involve high pressures (usually ambient air) ...
