Molecular Dynamics unravel the dependence of friction on the atomistic details of surfaces
Researchers at UCL in a collaboration study with Laurent Joly, from the University of Lyon, have investigated the friction properties of liquid water at the interface with graphene and with an hexagonal boron nitride sheet, using ab initio molecular dynamics for the...
Using a Single Molecule to Create a New Magnetic Field Sensor
A new way to use a single molecule as a magnetic field sensor has been discovered by LCN researchers at UCL and the University of Liverpool. In the study, published in Nature Nanotechnology, the scientists show how magnetism can manipulate the way electricity flows...
Stabilising Hard Axis Ferromagnetism by a Quantum Indian Rope Trick.
Random forces usually have a destabilising effect. A tightrope walker would rather not experience gusts of wind, for example. There are, however, cases where random forces can stabilize a system in state that would otherwise be unstable. The essential ingredient is...
