“…Actually, a temperature dependence of ε LB is also detected for both the solid (T < 0 °C) and the liquid (T > 0 °C) absorption at 2100−2650 cm −1 ; this is due to the strong sensitivity of ν LB to reveal the weakening of H-bonding interactions on increasing temperature within the ice or liquid water domain. 29,38 At low temperatures, the intensity of the band is proportional to ice concentration; the strong difference between pure water and water/DMSO solution shows that DMSO addition strongly reduces the amount of frozen water and shifts the melting temperature from 0 to −17 °C. 39 In Figure 5, the intensity of the water combination band for lipid suspensions is also shown; in the presence of lipid vesicles, we observe the same T ICE values of the relative solvent.…”

The properties of lipid membranes at low temperature are important for a number of biomedical and biotechnological applications, and the success of these applications depends on understanding the effects of temperature changes on intermolecular lipid-lipid and lipid-water interactions. Here, we use Fourier transform infrared spectroscopy to study lipid suspensions in water/dimethyl sulfoxide (DMSO) solutions in the -60 to 30 °C range. DMSO is a cryopreservative agent of cellular systems, and its action is largely related to its interaction with the lipid membrane, especially in the low-temperature regime. In the present work, we analyze the effects of solvent composition on the structural and thermotropic properties of cholesterol (chol)-loaded liposomes of palmitoyl-oleylphosphatidylcholine (POPC) because POPC/chol liposomes are suitable models of the plasmatic membrane. To this extent, we compare the properties of lipid vesicles suspended in water and water/DMSO solution at 0.10 DMSO mole fraction and we observe that the gel phase of the membrane has an increased thermal stability on DMSO addition. We estimate that the amount of unfrozen water at T = -60 °C is much reduced by the presence of DMSO, both in the gel- and the liquid-ordered phase of the membrane. Interestingly, we also evidence a reduced hydration of the lipid heads in the presence of DMSO when the vesicles are dispersed in a liquid solution, whereas the addition of DMSO does not alter the hydration state of phosphate and carbonyl groups in the frozen state of the membrane.

“…Additional tiny bands appear at 551, 765, and 2334 cm À1 (indicated by vertical arrows). These bands are associated with the Au-OH stretching mode, 32 e À (H 2 O), 33 and OH stretching, 34 respectively. The presence of these bands indicates that some water molecules are adsorbed on the Au surface.…”

“…Among the liquids that exist in nature, liquid water is probably the most complicated one, which demonstrates a number of anomalous properties [1,2]. The physical origins of the latter were discussed in works [3][4][5]. Water possesses unique properties of its behavior as a solvent [6][7][8].…”

На основi лiтературних даних проведено розрахунки та аналiз температурних i баричних залежностей термодинамiчного коефiцiєнта (∂V/∂T)P для води у станi рiдини. Проведено порiвняння вказаного коефiцiєнта для води та аргону. З урахуванням принципу вiдповiдних станiв пiдтверджено iснування областi термодинамiчної подiбностi мiж водою та аргоном. При цьому iснує область, в якiй зазначена подiбнiсть мiж водою та аргоном не спостерiгається i наявна особлива поведiнка термодинамiчних властивостей води. Так, у води крива температурної залежностi (∂V/∂T)P уздовж лiнiї рiвноваги рiдина–пара має точку перегину за температури (91,0 ± 0,2)∘C, чого не спостерiгається в аргонi. Iснування для води точки перегину кривої (∂V/∂T)P приводить до вiд’ємних значень (∂V/∂T)P при температурах, нижчих 3,98∘C. Крiм того, наявнiсть точки перегину на вказанiй температурнiй залежностi приводить до перетину температурних залежностей сiмейства iзобар (∂V/∂T)P у водi при температурi (42, 0 ± 0, 2)∘C. На вiдмiну вiд цього, кривi температурної залежностi (∂V/∂T)P аргону уздовж лiнiї рiвноваги рiдина–пара не мають вiдповiдної точки перегину.
