Properties of CaCl₂hydrate with an inorganic powder. Part 1.—Electrical conductivity of CaCl₂·nH₂O (n= 6.00–7.35) with α-Al₂O₃powder

Diffuse reflectance FT-IR spectroscopic study of interactions of α-Al2O3/molten alkali nitrate coexisting systems

“…Transport, thermodynamic, and spectroscopic properties have been studied by using different techniques such as electrical conductivity [6][7][8], differential scanning calorimetric (DSC) measurements [9][10][11][12][13], VIS spectroscopy [14], Raman scattering [15], EXAFS [16], and FT-IR [17]. The results have revealed that the structures and properties of the liquid phase in the interface with the solid phase are different from those of the bulk.…”

“…Deki et al [6][7][8][9][10][11][12][13][14][15][16] have been studying the structures and properties of the liquid phase in aqueous, nonaqueous, and molten salt electrolyte solutions with inorganic powder coexisting systems since the past decade. Transport, thermodynamic, and spectroscopic properties have been studied by using different techniques such as electrical conductivity [6][7][8], differential scanning calorimetric (DSC) measurements [9][10][11][12][13], VIS spectroscopy [14], Raman scattering [15], EXAFS [16], and FT-IR [17].…”

Solvent molecule mobilities in propylene carbonate-based electrolyte solutions coexisting with fumed oxide nanoparticles

“…Various studies have reported that the physical properties of a liquid in the neighborhood of a solid surface differ from those of the bulk solution [4][5][6][7][8]. Specifically, the physical properties of the solvent molecules within the pores of a porous material with a layered structure are very different from those in the bulk phase as a result of the extremely small pore volume and large specific surface area [9][10][11].…”

“…Yamada et al have reported that highly concentrated electrolytes improved the charge efficiency and breakdown voltage of LIBs [18]. Various measurement techniques such as thermodynamic measurements [5,19,20], spectrophotometric methods (e.g., Infrared and Raman spectrometries [6,19,[21][22][23][24], neutron scattering method [25], and X-ray scattering measurements [26]), and electrochemical measurement (e.g., electric conductivity measurement [7,19] and electrochemical impedance spectroscopy) has been used so far. Herein, we focus on NMR measurements in particular.…”

Anomalous properties of molten alkali nitrates coexisting with aluminum oxides by hetero-phase effect

“…Despite the success of this precision measurement method, it is still difficult to be applied to porous solid materials, because the incident light will probe only a single surface. Deki and Mizuhata et al have investigated the properties of the liquid phase in aqueous electrolyte solutions [5][6][7][8][9], hydrate [10][11][12][13], non-aqueous electrolyte solutions [14,15], and/or molten salt [16][17][18][19][20][21], coexisting with inorganic powders, and shown that the structures and properties of the liquid phase depend on the properties of the solid surface.…”
