Postdoctoral fellowship in solid-state NMR spectroscopy at CICECO – Aveiro Institute of Materials, Portugal within the Research Project PTDC/QEQ-QAN/6373/2014,financed by national funds through FCT/MEC and when applicable co-financed by FEDER under the PT2020 Partnership Agreement, under the following conditions:

Job description:

A 1-year postdoctoral position is readily available (with possibility for a 6-12 months extension) in NMR spectroscopy applied to functional sorbent materials at CICECO - Aveiro Materials Institute (www.ciceco.ua.pt), University of Aveiro. We are looking for candidates with self-initiative and previous NMR background, preferably, in solid-state NMR spectroscopy. The post-doctoral researcher should be independent working at the NMR spectrometer and able to program or/and adapt pulse sequences to run specific experiments to study selected nanoporous inorganic-organic hybrid materials (e.g., zeolite, modified mesoporous silicas, PMOs, MOFs); the main goal lies in gaining an atomic-level understanding of the surface interactions formed between these materials and strategically labeled gas mixtures, mimicking industrial flue gas streams relevant in post-combustion CO2 capture applications. In exceptional cases, the lack of relevant NMR experience can be compensated with a demonstrated knowledge in porous materials or quantum chemical calculations. He will work between different projects with the opportunity to tackle industrially relevant problems related to catalysis, environmental or pharmaceutical sciences, involving CICECO researchers & industrial partners.

Equipment: The successful candidate will take advantage of an interdisciplinary environment with privileged access to multiple solid-state characterisation equipments including 6 liquid/solid-state NMR spectrometers [Liquids: 300 and 500 MHz; Solids: 400, 500, 700 and 800 MHz magnets] with Bruker AV III HD consoles and a wide range of probes.

Scientific field: Materials Science; NMR spectroscopy

Academic Requirements / Qualifications:

- Prospective applicants should possess a PhD in Chemistry, Physics, Physical Chemistry, Materials, or related fields;

- Previous experience in NMR spectroscopy or pulse programming will be highly regarded (based on past peer-reviewed publications or any other equivalent indicator);

- Competencies in materials science or and/or computer modelling are also relevant skills for this position;

- Good English communication skills (oral + written) are mandatory;

- Applicants with experience in one or more of the topics below are greatly encouraged to apply.


a) NMR characterization or preparation/synthesis of functionalized/modified materials for gas capture applications;

b) Study of acid sites in crystalline and amorphous molecular sieves (e.g., zeolites);

c) DFT calculations of adsorbed molecules at surfaces and related computational methods.


Activity Outline: The project focus on the elucidation of CO2 adducts formed at gas partial pressures close to post-combustion CO2 capture applications. Specific gaseous NMR probes will be employed to study physi- and chemisorbed gas speciation in distinct nanoporous organic-inorganic hybrid systems available at CICECO institute. The study of surface species derived from flue gas contaminants is also envisaged. The NMR active nuclei of interest are 27Al, 11B, 17O, 13C, 1H, 2H, 19F among others. Good organizational skills are required to report the results to other researchers that will participate in group meeting discussions. The post-doctoral researcher, jointly with other researchers, will use an in-situ rotor packing apparatus to adsorb gases into the porous materials at variable-pressure and controlled temperature and moisture levels. We anticipate using 1D and 2D homonuclear and heteronuclear correlation techniques such as high-resolution/sensitivity enhancement techniques (e.g., RAPT, DFS, MQMAS/STMAS-related), 1H-based NMR methods, DQ-SQ correlation spectroscopy and double/triple resonance recoupling methods (e.g., RESPDOR, REAPDOR, TRAPDOR). Thus, familiarity with some of these techniques is a must but not mandatory. Some new techniques may need to be developed/implemented. Computational studies are also part of the project and can be performed in collaboration with CICECO senior modelers. It is expected that the determination of NMR parameters and other properties, via quantum mechanical calculations, will be necessary as well. The lab is equipped with several DFT codes to perform advanced computational studies (e.g., CASTEP, GAUSSIAN, VASP, Scienomics package, and a number of other related codes).

Place of work and supervision: The work will be carried out at CICECO –Aveiro Institute of Materials, University of Aveiro, Portugal, under the supervision of Dr. Luís Mafra.

Duration: The Post-doctoral grant will have an initial duration of 12 months, with the possibility to extend for 12 additional months, with a predicted starting date commencing by May 2017.

Grant amount: 1495 Euros/month (tax free) according to the official table for Research Grants from FCT - http://www.fct.pt/apoios/bolsas/valores, to be paid monthly via bank transfer.

Regulation: The fellowship is in accordance with Law Nº. 40/2004, 18th August (Research Fellow Statute) and Regulamento de Bolsas de Investigação da Fundação para a Ciência e Tecnologia — no. 234/2012, no. 326/2013 and no. 339/2015 ( http://www.fct.pt/apoios/bolsas/regulamento.phtml.pt ) and the Regulation of Scientific Research Grants from the University of Aveiro – Regulation n.º 341/2011, published in Diário da República, 2nd series, n.º 98, 20th Maio.

Opening date and deadline for applications: 29 of March to 19 of April, 2017.

Evaluation Criteria and Process: The evaluation criteria are: i) Final classification of Undergraduate (value: 2/20), Masters and Ph.D. (value: 3/20) degrees; ii) Previous international experience in related areas (value: 7/20); iii) Scientific publication record (value 5/20); The three candidates with better classification will be invited to an Interview (value 3/20). All eligible candidates will be ordered consecutively in terms of relative merit. The candidate rated highest in the relative merit list will be invited to fill the position. The candidates will be informed about the results by email.

Jury Composition: Luís Mafra, João Rocha and Zhi Lin.

Documents Required: i) Application letter mentioning the contacts of two or three references; ii) Curriculum Vitae; iii) 2-3 most relevant papers related to this position (other indicators of interest are welcome if necessary) iv) copy of ID card or passport; v) Academic degree certificate(s). The position will remain open until filled.

Applications should be sent by email to Dr. Luís Mafra (lmafra@ua.pt) within the time frame of the call.
