Structures and Anomalies of Water
Chuang Yao, Xi Zhang, Yongli Huang +3
Introduction of the principles of the asymmetrical, short-range O:H-O coupled oscillater pair and the basic rule for water ice, which reconciles the structure and anomalies of wate…
Hydrogen-bond relaxation dynamics: Resolving mysteries of water ice
Yongli Huang, Xi Zhang, Chang Q Sun
We examined O:H-O bond relaxation under compression,heating,molecular undercoordination and claimed a universal resolution to the best-known mysteries of water ice such as ice foat…
A common supersolid low-density skin sliperizing ice and toughening water surface
Xi Zhang, Yongli Huang, Zengsheng Ma +4
Skins of water and ice share the same attribute of supersolidity characterized by the identical H-O vibration frequency of 3450 cm-1. Molecular undercoordination and inter-electron…
A Supersolid Skin Covering both Water and Ice
Chang Q Sun
The mysterious nature and functionality of water and ice skins remain baffling to the community since 1859 when Farady firstly proposed liquid skin lubricating ice. Here we show th…
Mpemba Paradox Revisited -- Numerical Reinforcement
Xi Zhang, Yongli Huang, Zengsheng Ma +1
Inspired by responses to the work (arXiv:1310.6514), we solved the one-dimensional, nonlinear Fourier initial and boundary condition problem using the finite element method. Examin…
O:H-O Bond Anomalous Relaxation Resolving Mpemba Paradox
Xi Zhang, Yongli Huang, Zengsheng Ma +1
We demonstrate that the Mpemba paradox arises intrinsically from the release rate of energy initially stored in the covalent H-O part of the O:H-O bond in water albeit experimental…
Mechano-freezing of the ambient water
Xi Zhang, Tingting Yan, Bo Zou +1
Raman spectroscopy examination of the 25 deg-C water freezing under compression revealed transition from 1.35 GPa to 0.86 GPa upon ice being formed at continued volume change. The…
Skin supersolidity slipperizing ice
Xi Zhang, Yongli Huang, a Zengsheng Ma +2
Consistency between theory predictions and measurements and calculations revealed that the skin of ice, containing water molecules with fewer than four neighbours, forms a supersol…
Mass-density and Phonon-frequency Relaxation Dynamics of Under-coordinated Water Molecules
Chang Q. Sun
The interplay between intra-molecular H-O covalent bond contraction, due to molecular under-coordination, and inter-molecular O:H expansion, due to inter-electron pair Coulomb repu…
Mass-density and Phonon-frequency Relaxation Dynamics of Water and Ice at Cooling
Chang Q. Sun
Coulomb repulsion between the bonding electron pair in the H-O covalent bond (denoted by "-") and the nonbonding electron pair of O (":") and the specific-heat disparity between th…
Hydrogen bond relaxation dynamics and the associated symmetric, volumetric, vibronic, and phase transitional anomalies of frozen H2O under compression
Chang Q Sun, Xi Zhang, Weitao Zheng
Coulomb repulsion between the unevenly-bounded bonding "-" and nonbonding ":" electron pairs in the "O2- : H+/p-O2-" hydrogen-bond is found to originate the anomalies of low-compre…
Hydrogen bond relaxation dynamics and the associated vibronic and volumetric anomalies of H2O upon frozen
Xi Zhang, Xiaojian Fu, Yu Wen +4
A combination of the extended Ice Rule of Pauling, Raman spectroscopy, and molecular dynamics calculations has enabled us to clarify the bonding origin of the anomalous volume expa…
Zone-resolved photoelectronic scoping of the local bonding and electronic dynamics at the graphite skin with and without atomic vacancy and the associated graphene edge states
Chang Q. Sun, Yanguang Nie, Jisheng Pan +4
A zone-resolved photoelectron spectroscopy (ZPS) has enabled us to gain the local and quantitative information and hence confirm our theoretical expectations on the bonding and ele…
