Structure Evolution of Graphene Oxide during Thermally Driven Phase Transformation: Is the Oxygen Content Really Preserved?

Pengzhan Sun, Yanlei Wang, He Liu +4

A mild annealing procedure was recently proposed for the scalable enhancement of graphene oxide (GO) properties with the oxygen content preserved, which was demonstrated to be attr…

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…

Ultrafast Liquid Water Transport Through Graphene-Based Nanochannels Measured by Isotope Labelling

Pengzhan Sun, He Liu, Kunlin Wang +3

Graphene-based laminates, with ultralong and tortuous nanocapillaries formed by simply stacking graphene flakes together, have great promises in filtration and separation. However,…

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…

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…
