Field Ionisation (FI) and Field Desorption (FD) were pioneered by H D Beckey in the late 1960’s as ionisation techniques that offered significant advantages over then current methods. The heart of the system is an emitter that has dendrites (cf conifers/evergreens) on it which have extremely small radii on their tips. These dendrites allow very high electric field strengths to be applied to a molecule.

With Ohio Supercomputer Center access, Sadhan Jana at the University of Akron simulated the equilibrium state of organization of 12 organic tie-molecules on the surface of MWCNT. The red dots represent oxygen, white represent hydrogen, and gray represent carbon atoms in tie molecules.

Most classical molecular dynamics (MD) simulations employ potential functions that do not account for the effects of induced electronic polarization between atoms, instead treating atoms as simple fixed point charges. Incorporating the influence of polarization in large-scale simulations is a critical challenge in the progress toward computations of increased fidelity, providing a more realistic and accurate representation of microscopic and thermodynamic properties.
