DNA Structure: What's in Charge?

Journal of Molecular Biology, 2000
DNA structure is well known to be sensitive to hydration and ionic strength. Recent theoretical predictions and experimental observations have raised the idea of the intrusion of monovalent cations into the minor groove spine of hydration in B-form DNA.

Structure and charge distribution of multiply charged C70

Chemical Physics Letters, 1994
Abstract Spin-restricted Hartree—Fock molecular orbitals calculations have been performed for C n 70 (−6 ⩽ n ⩽ + 6) at a MNDO type semi-empirical level based on the PM3 parameterization. The optimized geometries reveal interesting variations in bond lengths.

On neutron charge structure

Czechoslovak Journal of Physics, 1991
The aim of the present work is to investigate the charge structure of neutron by calculating its root mean square charge radius 〈rn2〉1/2 and the corresponding charge form factor,Gn(q), within the general framework of quark-parton model. The neutron (the nucleon in general) is considered to be disc-like in conformity with the idea of Lorentz invariance.

Surface charging of silicon dioxide/silicon structures

2011 - 14th International Symposium on Electrets, 2011
The surface of silicondioxide/silicon structures is charged with the tip of a cantilever in contact mode by application of a voltage. Then, the surface potential is measured contactless using the Kelvin option of an atomic force microscope. On the position of the charged domain a potential difference in relation to the uncharged region is found.
