Quantum chemical evaluation of protein control over heme ligation: CO/O2 discrimination in myoglobin

Article Abstract:

A distal histidine residue through steric and H-bonding interactions tunes control of O2 versus CO binding in myoglobin. It is concluded that H-bonding from the distal histidine also stabilizes a side-on bound metastable isomer of the O2 adduct. which may play critical role in photodynamics.

Anisotropic adsorption of molecular assemblies on crystalline surfaces

Article Abstract:

The anisotropic adsorption of molecular assemblies on crystalline surfaces is analyzed. Torque aligns both micelles and protein fibrils and the interaction energy is minimized when the assembly lies perpendicular to a symmetry axis of a crystalline substrate.

Fucntionalized single graphene sheets derived from splitting graphite oxide

Article Abstract:

A process that produces single sheets of functionalized graphene through thermal exfoliation of graphite oxide is described. The process yields a wrinkled sheet structure resulting from reaction sites involved in oxidation and reduction processes.
