A partially melted ice nanoparticle at about -100 degrees Celsius

Nano ice melts at -100 degrees!

25th March 2011

Computer simulations provide a molecule’s eye view of the melting of ice nanoparticles, predicting melting at very low temperatures. The melting of ice is a very familiar process but its ubiquity belies its importance. It plays a ...

A view of the ice surface illustrating weakly, (red), intermediate (white) and strongly bound water molecules (blue). White molecules are at the external surface, grey lie sub-surface.

Large variation in ice surface vacancies

25th March 2012

Ice exhibits a phenomenon known as pre-melting which was first alluded to by Michael Faraday in his ‘regelation’ experiments at the Royal Institution in the 1850’s. A liquid like layer forms at the surface of ice, but ...

Simulating water slippage

25th January 2015

Friction is one of the main sources of dissipation. For instance, about one third of the world mechanical energy is dissipated into friction [1]. Understanding nanoscale friction at the interface between a liquid and a solid is also ...

Nanodroplets surfing on graphene

25th January 2016

The motion of atoms, molecules and clusters across the surfaces of materials is of critical importance to an endless list of phenomena.ion across surfaces generally involves motion on a vibrating but otherwise stationary substrate. H ...

QMC on 2D ice paper published at Phys. Rev. B

7th December 2016

In this work, Ji, Andrea and Gerit have worked together in re-evaluating the stability of so-called two-dimensional (2D) ice, one of the most interesting and controversial topics about ice in recent years. Recent experiments on ice ...
