The Ceramic and Cement-based materials Group ( https://cfm.ehu.es/C2M ) seeks a well-motivated postdoc to join a highly multidisciplinary project funded by the EU (H2020-FET-OPEN MIRACLE) which aims to design new concretes with radiative cooling capacity. In particular, the candidate will work in the computational (atomistic) description of the coupling of light with cementitious phases and how these materials can be tuned for enhancing their radiative cooling efficiency. The selected candidate will be hired by the Spanish National Research Council (CSIC) and the duration of the appointment will be of 2-3 years. The preferred starting date will be March 2021. The salary will be of approximately 35,000euros per year before taxes. The candidate should demonstrate previous experience in atomistic simulations (ab-initio and/or force field simulations). The following points are not required to apply, but they will be considered in the evaluation process as convenient. * Experience in cement-based materials and/or similar materials like clays and zeolites. * Experience in phonons and thermal properties of materials. * Previous knowledge on radiation-matter interactions. Suitable candidates are requested to submit: 1-A presentation letter with a declaration of interests (max. 1 page). 2- A Curriculum Vitae, including a list of publications. 3-Two reference letters and/or contact email of two potential referees. The application for the contract will be opened from the 1st of Dec 2020 to 1st March 2021, but it will be extended in case no appropriate candidate is found. Do not hesitate to contact Jorge S. Dolado by email ([email protected]) for further clarifications.
