Solvation Dynamics

Chang Q Sun, FRSC, FInstP, received his B.Sc. in 1982 from Wuhan University of Science and Technology and an M.Sc. in 1987 from Tianjin University and served on its faculty until 1992. He earned his Ph.D. in Surface Physics at Murdoch University in 1996 and then joined Nanyang Technological University.  Dr Sun has been working on the theme of Extraordinary Coordination Bonding and Nonbonding Electronics. He has pioneered theories of Chemical Bond Relaxation and Hydrogen Bond (O:H-O) Oscillator Pair Cooperativity and holds multiple patents on the Coordination-Resolved Electron and Multifield Phonon Spectrometrics. Original contributions include the following with atomistic, dynamic, local, and quantitative information on performance of bonds, electrons, and phonons under perturbation: 1.Revelation of the four-stage bonding dynamics and four valence states of oxidation.2.Reconciliation of atomic irregular-coordination, size dependency of nanostructures, single-bond multifield mechanics, lattice oscillation dynamics, and coordination-resolved catalysis.3.Resolution of anomalies of water and ice such as ice floating, friction, regelation and Mpemba paradox with clarification of quasisolid phase transition and undercoordination supersolidity.4.Clarification of the effect of charge (electron, proton, ions, lone pair, dipoles) injection by solvation on the hydrogen bonding network and solution properties through O:H nonbond, H↔H anti-HB, O:⇔:O super-HB, electrostatic shielding and screening. His contribution has been documented in four monographs published in Springer Series of Chemical Physics and their Chinese versions. He has published over 20 treatises in Chemical Reviews etc. He  was bestowed with the first rank of the 25th Khwarizmi Award in 2012 and the inaugural Nanyang Award in 2005.
