Job announcements relevant to people interested in electronic structure calculations…
Due to the large number of posts recently, there is currently a delay of several weeks between posts being submitted and the corresponding emails being distributed to all users. Please bear with us while we try to improve this. In the meantime – and until this notice is removed – it would assist us considerably if you could submit only important and/or urgent posts and thus help to reduce the size of the mail queue. Under no circumstances should you resend posts multiple times when you find the emails are not distributed immediately.
In light of the Russian military offensive in Ukraine, we request that announcements relating to events, jobs and other activities associated with institutions supported by the Russian and Belarusian states are not posted to the Psi-k forum.

Title of the Research: Atomistic simulations of adhesion of graphene-based coatings in combination with magnetic layers
Description: Drag reduction in automotive and aeronautical components is a key sustainability strategy to improve efficiency, reduce energy consumption, and cut greenhouse gas emissions. In parallel, self-cleaning coatings allow to increase performance and reliability, while reducing maintenance costs. These two effects are deeply intertwined, being based on low-friction/low-drag and possibly (super- )hydrophobic interactions between surfaces and gasses. Hence, the microscopic understanding of the energetics and dynamics at the interface between air and lowdrag coated surfaces under high-speed conditions (potentially up to the supersonic and hypersonic regimes) could help the design and optimization of novel low-drag materials for terrestrial, aerial, and space applications. In this project, we will leverage state-of-the-art ab initio atomistic simulations and multi-scale approaches to tackle the potential low-drag and self-cleaning properties of graphene-based coatings. the target substrates will be aluminum and alumina. Therefore, the candidate will investigate the adhesion of ferromagnetic compounds on Al/Al2O3 substrates protected with a top layer of h-BN/graphene, as innovative components that could produce magneto-friction effects for O2, slip condition for N2, and at the same time act as a potential radar-frequencies absorbing material. The candidate will have to perform ab initio calculations both in the gas-phase and in the condensed ones: bulk and hybrid. Experience with calculations with magnetic systems and/or using software packages such as ORCA, CP2K, MOLCAS, and QuantumEspresso will be considered a plus.
The project has been commissioned by international and national companies and it represents an opportunity to get in contact with their R&D area.
