Revealing the multi-bonding state between hydrogen and graphene-supported Ti clusters [PDF]

open access: yesJ. Phys. Chem. C 2016, 120, 12974-12979, 2016
Hydrogen adsorption on graphene-supported metal clusters has brought much controversy due to the complex nature of the bonding between hydrogen and metal clusters. The bond types of hydrogen and graphene-supported Ti clusters are experimentally and theoretically investigated. Transmission electron microscopy shows that Ti clusters of nanometer-size are

Energy considerations show that low-barrier hydrogen bonds do not offer a catalytic advantage over ordinary hydrogen bonds [PDF]

open access: yesProceedings of the National Academy of Sciences, 1996
Low-barrier hydrogen bonds have recently been proposed as a major factor in enzyme catalysis. Here we evaluate the feasibility of transition state (TS) stabilization by low-barrier hydrogen bonds in enzymes. Our analysis focuses on the facts that ( i ) a low-barrier hydrogen bond is less stable than a regular ...

Hydrogen Bonds in Excited State Proton Transfer [PDF]

open access: yesPhys. Rev. Lett. 117, 163002 (2016), 2017
Hydrogen bonding interactions between biological chromophores and their surrounding protein and solvent environment significantly affect the photochemical pathways of the chromophore and its biological function. A common first step in the dynamics of these systems is excited state proton transfer between the non-covalently bound molecules, which ...

Hydrogen Absorption Properties of Metal-Ethylene Complexes [PDF]

open access: yes, 2007
Recently, we have predicted [Phys. Rev. Lett. 97, 226102 (2006)] that a single ethylene molecule can form stable complexes with light transition metals (TM) such as Ti and the resulting TMn-ethylene complex can absorb up to ~12 and 14 wt % hydrogen for n=
