5Experimental tests for a liquid-liquid critical point in water显示文摘Water is a fascinating material.Its composition is simple—one oxygen and two hydrogen atoms—but its chemistry and physics are extremely complex and exhibit 75 documented anomalies.Although these anomalies and their molecular origin are not completely understood,we know that hydrogen bonds play key roles in all of the phases of water.Moreover,there is experimental evidence that the polymorphism of the ice structure extends into the liquid phase and is associated with a liquid-liquid coexistence line.This is currently a topic of great interest in water research because there are indications that the end point of the coexistence line corresponds to a second critical point inside the supercooled liquid regime.We examine the recent progress in understanding water anomalies and the liquid-liquid phase transition hypothesis,including the results of recent experimental work and molecular simulations of both bulk and confined water.We examine experimental results that test whether the behavior of liquid water is consistent with the'liquid polymorphism'hypothesis that liquid water can exist in two distinct phases of differing densities.We also examine recent research on the anomalies of nanoconfined water and,in particular,on water in biological environments.We find that the concept of liquid polymorphism can also describe the properties of other liquids that have two characteristic length scales.Domenico Mallamace Carmelo Corsaro Francesco Mallamace H.Eugene Stanley 2020Science China(Physics,Mechanics & Astronomy)2020,63,12:0
6Preface to the special topic: New advances in water and water systems显示文摘Water and related systems play a central role in science and technology.Although water has unusual and anomalous behaviors,if compared with normal liquids,it is of fundamental interest in many research fields going from chemical-physics to life sciences.The first and well known example of these anomalies is the density maximum,at 277 K,intuited by Galilei[1]in 1612 and lately discovered in Florence[2].LiMei Xu Francesco Mallamace 2019Science China(Physics,Mechanics & Astronomy)2019,62,10:0
7Hydrophilic 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 2019Science China(Physics,Mechanics & Astronomy)2019,62,10:0
8The Boson peak interpretation and evolution in confined amorphous water显示文摘We study the evolution of the Boson peak for water confined in cement paste obtained by means of Inelastic Neutron Scattering from room temperature to the deep supercooled regime.We analyze the data in terms of a universal-like model,developed for glass forming liquids in the frame of the energy landscape.In such a way it is possible to discriminate between the fragile and strong glass forming character of supercooled liquids and the dynamical crossover,fragile to strong,between them.Hence,we confirm the link between the Boson peak and the water polymorphism.In particular,the main result is represented by a crossover from a local energetic minima configuration to that characteristic of saddle points on going towards the deep supercooled regime up to the dynamical arrest.Francesco Mallamace Carmelo Corsaro Domenico Mallamace Sow-Hsin Chen Emiliano Fratini Piero Baglioni 2019Science China(Physics,Mechanics & Astronomy)2019,62,10:0
9A study of the hydrogen bonds effect on the water density and the liquid-liquid transition显示文摘We study the hydrogen bonds effect on the water density as a function of temperature and pressure from the supercritical region to the metastable supercooled and amorphous phases.We identify two important thermodynamic thresholds,that is P^*≈2 kbar and r^*≈315 K,that separate two different water behaviors in terms of hydrogen bonding capability.For TFrancesco Mallamace Carmelo Corsaro Enza Fazio Sow-Hsin Chen Domenico Mallamace 2019Science China(Physics,Mechanics & Astronomy)2019,62,10:0
10The onset of the tetrabonded structure in liquid water显示文摘Water properties are dominated by the hydrogen bond interaction that gives rise in the stable liquid phase to the formation of a dynamical network.The latter drives the water thermodynamics and is at the origin of its well known anomalies.The HB structural geometry and its changes remain uncertain and still are challenging research subjects.A key question is the role and effects of the HB tetrahedral structure on the local arrangement of neighboring molecules in water.Here the hydrogen dynamics in bulk water is studied through the combined use of Neutron Compton Scattering and NMR techniques.Results are discussed in the framework of previous studies performed in a wide temperature range,in the liquid,solid,and amorphous states.For the first time this combined studies provide an experimental evidence of the onset of the water tetrahedral network at T^315 K,originally proposed in previous studies of transport coefficients and thermodynamical data;below this temperature the local order in water changes and the lifetime of local hydrogen bond network becomes long enough to gradually develop the characteristic tetrahedral network of water.Carla Andreani Carmelo Corsaro Domenico Mallamace Giovanni Romanelli Roberto Senesi Francesco Mallamace 2019Science China(Physics,Mechanics & Astronomy)2019,62,10:0
