Journal ArticleDOI
Reactive Molecular Dynamics study on the first steps of DNA-damage by free hydroxyl radicals
TL;DR: It is illustrated that the randomly distributed clusters of diatomic OH radicals that are primary products of megavoltage ionizing radiation in water-based systems are the main source of hydrogen abstraction as well as formation of carbonyl and hydroxyl groups in the sugar moiety that create holes in the Sugar rings.
Journal ArticleDOI
Reactive molecular dynamics study on the first steps of DNA damage by free hydroxyl radicals.
TL;DR: In this article, a large-scale molecular simulation based on bond-order ReaxFF was employed to simulate the chemical reaction and study the damage to a large fragment of DNA molecule in the solution by ionizing radiation.
Journal ArticleDOI
Multiscale QM/MM molecular dynamics study on the first steps of guanine damage by free hydroxyl radicals in solution.

TL;DR: A multiscale and hybrid quantum mechanical-molecular mechanical simulation is employed to study the interaction of OH radicals with a guanine-deoxyribose-phosphate DNA molecular unit in the presence of water, where all of the water molecules and the deoxyribosing fragment are treated with the simplistic classical molecular mechanical scheme.

Tailoring Magnetism in Quantum Dots
Journal ArticleDOI
Piezomagnetic Quantum Dots
TL;DR: A reentrant magnetic ordering is revealed with the increase of elliptical deformation and it is suggested that the piezomagnetic quantum dots can be used as nanoscale magnetic switches.
