“…To analyze the change of the average energy of hydrogen bonds in water using Raman spectrum the authors of this study suggested the use of quantitative characteristics of stretching bands as the ratio of the intensities of high-frequency and low-frequency regions of the stretching band (Figure a) χ 21 = I 2 / I 1 and the shift of mass center. − As it was calculated using temperature dependence of water Raman stretching band, the average energy of hydrogen bonds in water is equal to |−21.4| kJ/mol. Assuming that the high-frequency region of stretching band (with maximum 2 and intensity I 2 , Figure a) is caused by vibrations of hydroxyl groups with weak hydrogen bonds and the low frequency region (with maximum 1 and intensity I 1 ) caused by vibrations of groups with strong hydrogen bonds, then the parameter χ 21 characterizes the ratio of fractions of OH groups with weak and strong hydrogen bonds.…”

The use of detonation nanodiamond (DND) slurries in biomedical applications requires the understanding of interactions at the particle/solvent interphase. In this article, interactions of nanodiamond particles with molecules of protic solvents (water and water−ethanol mixture) were studied by the methods of laser Raman and fluorescence spectroscopy. It was found that nanodiamonds modified by carboxyl groups significantly decrease the average hydrogen bonds energy in protic solvents. In turn, the strength of hydrogen bonds at the DND/solvent interphase influences the fluorescent properties of nanodiamonds: the weaker the effect of the hydrogen bonds, the stronger is the fluorescence of DNDs in suspensions.

“…Instead, the solvent presumably forms a homogenous mixture through the samples, at least at the length scales investigated in our experiments. Those length scales are indeed too large to probe the solvent clusters that may form in water/ethanol mixtures [46][47][48] .…”

“…To further reveal the electrochemical stability of LN-SDS-n, room-temperature Raman spectra were collected as shown in Figure 1 b. A dramatic increase in v as (CH 3 ,CH 2 ) and v s (CH 3 ,CH 2 ) signals (2800–3000 cm −1 ) occurs as n ≥ 30, showing the existence of SDS [ 60 ]. However, the v (OH) band (3000–3800 cm −1 ) decreases in intensity as n increases to 90 and then increases at n equals 120.…”

Low-cost and ecofriendly electrolytes with suppressed water reactivity and raised ionic conductivity are desirable for aqueous rechargeable batteries because it is a dilemma to decrease the water reactivity and increase the ionic conductivity at the same time. In this paper, Li2SO4–Na2SO4–sodium dodecyl sulfate (LN-SDS)-based aqueous electrolytes are designed, where: (i) Na+ ions dissociated from SDS increase the charge carrier concentration, (ii) DS−/SO42− anions and Li+/Na+ cations are capable of trapping water molecules through hydrogen bonding and/or hydration, resulting in a lowered melting point, (iii) Li+ ions reduce the Krafft temperature of LN-SDS, (iv) Na+ and SO42− ions increase the low-temperature electrolyte ionic conductivity, and (v) SDS micelle clusters are orderly aggregated to form directional ion transport channels, enabling the formation of quasi-continuous ion flows without (r.t.) and with (≤0 °C) applying voltage. The screened LN-SDS is featured with suppressed water reactivity and high ionic conductivity at temperatures ranging from room temperature to −15 °C. Additionally, NaTi2(PO4)3‖LiMn2O4 batteries operating with LN-SDS manifest impressive electrochemical performance at both room temperature and −15 °C, especially the cycling stability and low-temperature performance.
