Molecular Dynamics Simulations of Aluminum Foams under Tension: Influence of Oxidation

2018

For materials with high surface-to-volume ratio and high oxygen affinity, oxide layers will significantly change the material properties. However, oxidation effects have not been studied for metal nanofoams, which have many applications because of their light weight and high stiffness. We use molecular dynamics simulations to show that oxidized aluminum nanofoams possess significantly improved ductility without reduction in tensile strength. The Al−O interface leads to an increased defect nucleation rate at the oxide interface, preventing localized deformation. At the same time, the enthalpy of mixing between aluminium and oxygen decreases for increasing O concentrations, reaching a minimum at the stoichiometric ratio of Al 2 O 3 , resulting in stabilized bonds and increased strength.

“…Experiments synthesising nucleic acid bases and glycine in a reducing atmosphere containing CH4, CO, N2 and H2O used a shock-wave simulating an asteroid impact as an energy source. The shock wave generated in this high power laser experiment reaches velocities up to 60 km s -1 and with local pressures as high as 3.6 Mbar [190]. When experimentally simulating the conditions of an extraterrestrial body impact [191] it turns out that mixtures containing carbon, hydrogen, oxygen and nitrogen molecular form, e.g.…”

Ariel – a window to the origin of life on early earth?

et al. 2020

Is there life beyond Earth? An ideal research program would first ascertain how life on Earth began and then use this as a blueprint for its existence elsewhere. But the origin of life on Earth is still not understood, what then could be the way forward? Upcoming observations of terrestrial exoplanets provide a unique opportunity for answering this fundamental question through the study of other planetary systems. If we are able to see how physical and chemical environments similar to the early Earth evolve we open a window into our own Hadean eon, despite all information from this time being long lost from our planet's geological record. A careful investigation of the chemistry expected on young exoplanets is therefore necessary, and the preparation of reference materials for spectroscopic observations is of paramount importance. In particular, the deduction of chemical markers identifying specific processes and features in exoplanetary environments, ideally "uniquely". For instance, prebiotic feedstock molecules, in the form of aerosols and vapours, could be observed in transmission spectra in the near future whilst their surface deposits could be observed from reflectance spectra. The same detection methods also promise to identify particular intermediates of chemical and physical processes known to be prebiotically plausible. Is Ariel truly able to open a window to the past and answer questions concerning the origin of life on our planet and the universe? In this paper, we discuss aspects of prebiotic chemistry that will help in formulating future observational and data interpretation strategies for the Ariel mission. This paper is intended to open a discussion and motivate future detailed laboratory studies of prebiotic processes on young exoplanets and their chemical signatures.

“…These materials have a wide range of application in the laserplasma interaction experiments. They are used for the study of equations of state [2,3] and shock waves [4,5] , for increasing the efficiency of absorption of laser energy [6,7] and of its conversion into X-rays [8] , as bright neutron sources [9] , and to enhance electron acceleration by short laser pulses [10][11][12][13] . In the direct-drive approach towards inertial confinement fusion (ICF), foams of overcritical density have been suggested to be employed as absorbers for the fusion capsule being able to increase the ablation loading on the target surface [14] .…”

Porous materials have many applications for laser–matter interaction experiments related to inertial confinement fusion. Obtaining new knowledge about the properties of the laser-produced plasma of porous media is a challenging task. In this work, we report, for the first time to the best of our knowledge, the time-dependent measurement of the reflected light of a terawatt laser pulse from the laser-produced plasma of low-Z foam material of overcritical density. The experiments have been performed with the ABC laser, with targets constituted by foam of overcritical density and by solid media of the same chemical composition. We implemented in the MULTI-FM code a model for the light reflection to reproduce and interpret the experimental results. Using the simulations together with the experimental results, we indicate a criterion for estimating the homogenization time of the laser-produced plasma, whose measurement is challenging with direct diagnostic techniques and still not achieved.
