Biography
Focus has been given on the theme of Coordination Bond and Electronic Engineering since 1990 with the development of an original set of theoretical, experimental, and numerical strategies and multiple breakthroughs, which include:

Theoretical approaches:

1. Bond-band-barrier (3B) correlation theory has unified C, N, and O surface chemisorption on various solid surfaces and hetero-junction interface 3B dynamics;
2. Bond order-length-strength (BOLS) correlation theory has unified the unusual performance of undercoordinated defect, surface, and the size dependence and emergence (of new features) of atomic clusters;
3. Nonbonding electron polarization (NEP) for the size emergence of catalytic, ferromagnetic, and hydrophobic anomalies at defect sites and at small scales;
4. Hydrogen-bond asymmetric relaxation dynamics and physical anomalies of H2O under compression, thermal excitation, and molecular undercoordination;

Numerical algorithms:

5. Local-bond-average (LBA) approach for solid meso-mechano-thermo physical chemical dynamics;
6. Functionalization of the macroscopic performance to the bond-electron-energy attribute of a substance;
7. BOLS-TB algorithm for local bond relaxation and electron binding-energy shift in terms of quantum entrapment, localization, and polarization;

Experimental Innovations:

8. Zone-selective photoelectron spectroscopic (ZPS, US patent) purification of local bond relaxation & electron energetics pertaining to under- and hetero-coordinated atoms at the atomic scale;
9. Raman quantification of the length, energy, compressibility, Debye temperature, force constant & relaxation dynamics of bonds;
10. STM/S and VLEED quantification of 4-stage Cu3O2 bonding kinetics;

Breakthroughs:

11. Reproduction of the Mpemba paradox with revelation of hydrogen bond memory and water skin supersolidity;
12. Determination of the temperature dependence of the breaking limit of monoatomic chains, energy levels of an isolated atoms; specific heat per bond; and the bond strain and binding energy at graphene edges, graphite point defects and monolayer skin, etc;
13. PZT intense blue light emission, TiCN buffering for diamond-metal adhesion, photonic switches;
14. Unification of mesoscopic super-elasticity, plasticity, and rigidity, super-hydrophobicity, fluidity, lubricity, and solidity, and the meso-mechano-thermo physical chemistry of ZnO, graphene, Si, H2O, etc.

Contributions have been documented in a Monograph on Relaxation of the Chemical Bond (Springer Press, 2014) and some 10 themed reports published in Chemical Society Reviews’14, Surface Science Reports’13, Chemical Reviews’12, Science in China’ 12, Energy Env Science’11, Nanoscale’10, Progress in Materials Science’09 and 03, Prog in Solid State Chemistry’ 07 and 06, etc., in addition to 300 journal articles, and over 100 invited talks. Particularly, recent discoveries in water ice have been highly regarded by Chemistry World, Chemistry Views, Physics Today, IOP Physics, Time, The Telegraph, Daily Mails, etc. His theories have been adopted as teaching references by educational institutions globally.
