FURTHER SIMULATIONS DETAILS To construct the NP, the ASE package1 was used: 6 atomic layers were used in the f1,0,0g family of directions; 9 layers in the f1,1,0g family; and 5 layers in the f1,1,1g family, except along the (1¯; 1¯; 1)¯ direction where no layers were used. As the equations of motion for the atoms in the NP were not integrated (i.e. they were fixed) no interaction potential was defined between them, and the adsorption energy Eads of a water monomer to the NP was therefore simply defined as the total energy after geometry optimization of a single water molecule at the center of the (111) face. The velocity Verlet algorithm was used to propagate the equations of motion of the water molecules, using a 10 fs time step.

  • Rosetta Craft Makes Historic Comet Rendezvous European Space Agency's Comet-Chasing Mission Arrives After 10-Year Journey
    NATURE | NEWS Rosetta craft makes historic comet rendezvous European Space Agency's comet-chasing mission arrives after 10-year journey. Elizabeth Gibney 06 August 2014 ESA/Rosetta/MPS for OSIRIS Team MPS/UPD/LAM/IAA/SSO/INTA/UPM/DASP/IDA Comet 67P/Churyumov–Gerasimenko, as seen by Rosetta from a distance of 285 kilometres. No one can deny that it was an epic trip. The European Space Agency's comet-chasing Rosetta spacecraft has arrived at its quarry, after launching more than a decade ago and travelling 6.4 billion kilometres through the Solar System. That makes it the first spacecraft to rendezvous with a comet, and takes the mission a step closer to its next, more ambitious goal of making the first ever soft landing on a comet. Speaking from mission control in Darmstadt, Germany, Matt Taylor, Rosetta project scientist for the European Space Agency (ESA), called the space mission “the sexiest there’s ever been”. Rosetta is now within 100 kilometres of its target, comet 67P/Churyumov–Gerasimenko (or 67P for short), which in July was discovered to be shaped like a rubber duck. After a six-minute thruster burn, at 11:29 a.m. local time on 6 August, ESA scientists confirmed that Rosetta had moved into the same orbit around the Sun as the comet. Rosetta is now moving at a walking pace relative to the motion of 67P — though both are hurtling through space at 15 kilometres per second. Unlike NASA’s Deep Impact and Stardust craft, and ESA’s Giotto mission, which flew by their target comets at high speed, Rosetta will now stay with the comet, taking a ring-side seat as 67P approaches the Sun, and eventually swings around it in August 2015.

  • What Makes a Good Descriptor for Heterogeneous Ice Nucleation on OH-Patterned Surfaces
    What Makes a Good Descriptor for Heterogeneous Ice Nucleation on OH-Patterned Surfaces Philipp Pedevilla Thomas Young Centre and London Centre for Nanotechnology, 17-19 Gordon Street, London, WC1H 0AH, United Kingdom and Department of Chemistry, University College London, 20 Gordon Street, London, WC1H 0AJ, United Kingdom Martin Fitzner and Angelos Michaelides∗ Thomas Young Centre and London Centre for Nanotechnology, 17-19 Gordon Street, London, WC1H 0AH, United Kingdom and Department of Physics and Astronomy, University College London, Gower Street, London, WC1E 6BT, United Kingdom (Dated: October 5, 2018) Freezing of water is arguably one of the most common phase transitions on Earth and almost always happens heterogeneously. Despite its importance, we lack a fundamental understanding of what makes substrates efficient ice nucleators. Here we address this by computing the ice nucleation (IN) ability of numerous model hydroxylated substrates with diverse surface hydroxyl (OH) group arrangements. Overall, for the substrates considered, we find that neither the symmetry of the OH patterns nor the similarity between a substrate and ice correlate well with the IN ability. Instead, we find that the OH density and the substrate-water interaction strength are useful descriptors of a material's IN ability. This insight allows the rationalization of ice nucleation ability across a wide range of materials, and can aid the search and design of novel potent ice nucleators in the future. I.

  • Public Request to Take Stronger Measures of Social Distancing Across the UK with Immediate Effect 14Th March 2020
    Public request to take stronger measures of social distancing across the UK with immediate effect 14th March 2020 (last update: 15th March 2020, 18:25) As scientists living and working in the UK, we would like to express our concern about the course of action announced by the Government on 12th March 2020 regarding the Coronavirus outbreak. In particular, we are deeply preoccupied by the timeline of the proposed plan, which aims at delaying social distancing measures even further. The current data about the number of infections in the UK is in line with the growth curves already observed in other countries, including Italy, Spain, France, and Germany [1]. The same data suggests that the number of infected will be in the order of dozens of thousands within a few days. Under unconstrained growth, this outbreak will affect millions of people in the next few weeks. This will most probably put the NHS at serious risk of not being able to cope with the flow of patients needing intensive care, as the number of ICU beds in the UK is not larger than that available in other neighbouring countries with a similar population [2]. Going for \herd immunity" at this point does not seem a viable option, as this will put NHS at an even stronger level of stress, risking many more lives than necessary. By putting in place social distancing measures now, the growth can be slowed down dramatically, and thousands of lives can be spared. We consider the social distancing measures taken as of today as insufficient, and we believe that addi- tional and more restrictive measures should be taken immediately, as it is already happening in other countries across the world.

At arrival the Comet was still far away from the Sun and relatively inactive allowing orbits close to the Comet (distance about 8 km). In November 2014, the Philae lander was deployed from the Rosetta orbiter onto the Comet's surface. After this historic event the orbiter continued its mission by escorting the Comet for approximately one and a half year throughout perihelion and beyond. As the Comet got closer to the Sun its activity increased creating new operational challenges along with interesting observation opportunities. Increasing comet activity, resulting in an increased dust envi- ronment near the nucleus, forced the Rosetta orbiter to follow trajectories further away from the Comet.
