| 1 | Hydrophilic and hydrophobic competition in water-methanol solutions显示文摘We study the thermal behavior of the longitudinal spin-lattice,T1,and the transverse spin-spin,T2,relaxation times of the macroscopic magnetization in water/methanol solutions.Our aim is to investigate the reciprocal influence of hydrophobic effects on water properties and of hydrophilicity(via hydrogen bond,HB,interactions)on the solute.Using classical Nuclear Magnetic Resonance spectroscopy,we find a single characteristic correlation time r c that reflects all local structural configurations and characterizes the thermal motion effects of the magnetic nuclei on the spin-spin interaction.We find that in the supercooled regime the correlations are stronger,with respect to ambient temperature,because the HB interactions have a lifetime long enough to sustain a stable water network.However,increasing the temperature,progressively decreases the HB interaction lifetime and destroys the water clusters with a consequent decoupling in the dynamic modes of the system.In addition,at temperatures higher than about 265 K,the hydrophobicity becomes gradually stronger and governs the physical properties of the solutions. | Domenico Mallamace Sow-Hsin Chen Carmelo Corsaro Enza Fazio Francesco Mallamace HEugene Stanley | 2019 | Science China(Physics,Mechanics & Astronomy)2019，62，10： | 0 |
