Postdoc in composite metamaterials for aeronautical application at the Federal Institute of Maranhão.

Posted on Sunday 30 de April de 2023

Professor Edson Miranda Jr. (http://lattes.cnpq.br/9782653543954493) has 1 (one) position open for a postdoctoral position in the area of DYNAMICS
AND VIBRATION OF COMPOSITE METAMATERIALS FOR AERONAUTICAL APPLICATION, in the Department of Mechanical and Materials of the Federal Institute of Maranhão (for the simulation part, it is not necessary to be full-time in São Luís-MA).

The position is to work in a project funded by CNPq, specifically with experiments and modelling of dynamical systems, wave propagation, and passive vibration control applied to aeronautical engines. The researcher will have the opportunity to collaborate with outstanding research groups, mainly, in
Brazil and Italy.

The candidate should have a doctorate degree in Mechanical Engineering or related areas.

Knowledge and experience on finite element modelling, wave propagation, periodic systems, mechanical vibration, composite materials, and signal processing are desired.

Knowledge of MATLAB and good English are mandatory.

Knowledge of COMSOL software, plane wave expansion (PWE) approach, and composite material manufacturing are differentials.

The scholarship is of R$ 4.500,00 (SET-C) from now (april/2023) until 11/17/2025 (the end of the project).

The interested should send the following documents to edson.jansen@ifma.edu. The documents are:

1) A detailed CV with research experience and average graduate degree results.

2) A motivation letter detailing how your research profile and interest relate to the project.

3) A recommendation letter from researcher or professor.

An online interview shall be scheduled after the evaluation of the documents.

Postdoctoral Research Scientist in perovskite solar cells

Posted on Monday 6 de June de 2022

The group of Prof. Carlos F. O. Graeff at Faculty of Sciences from São Paulo State University (UNESP), in Bauru (Brazil), is looking for 1 postdoctoral research scientist. The application deadline for the positions is 15/07/2022. The candidates are expected to design, produce and characterize perovskite solar cells (PSCs).

About the Project

The present project aims on comprehending the degradation mechanisms involved in PSCs, and on finding solutions to overcome the stability issues of these devices. Based on this premise, several chemical and physical aspects will be investigated which includes; synthesis of different perovskite light harvester materials, analysis of interfacial and defects phenomena, search for optimal electron and hole transport layers materials, use of promising novel techniques for materials and devices characterization and novel device configurations. These investigations will converge to the primary objective of this work which consists of proposing more stable and more efficient PSCs.

Key project aims

I. To optimize perovskite compositions in order to minimize defects during crystallization and thin-film deposition steps.
II. To design novel electron and hole transport layers as alternatives for the currently low stable used materials.
III. To characterize the structure, morphology and optical properties of nanomaterials as active components in PSCs;
IV. To study defects and their effects on PSCs by using advanced spectroscopic and electrical techniques such as photothermal deflection spectroscopy (PDS) and photo-CELIV.

Requirements and how to apply

– Ph.D. in Physics, Materials Science & Engineering, Chemistry, or related areas.
– Experience in fabrication and characterization of perovskite solar cells is necessary.
– Experience on a variety of film deposition methods (blade-coating, roll-to-roll, etc) will be positively evaluated.
– Previous experience with the characterization techniques PDS or CELIV is a plus.
– English knowledge (fluent in writing and speech).

Each selected candidate will receive a Post-Doctoral fellowship from the São Paulo Research Foundation (FAPESP) in the amount of R$ 8.479,20 monthly and a research contingency fund, equivalent to 10% of the annual value of the fellowship which should be spent in items directly related to the research activity

Candidates should contact Prof. Carlos F. O. Graeff (carlos.graeff@unesp.br) with a brief statement of research interest/cover letter, a CV, and contact information of 2-3 references. Students in their final year of Ph.D. training are encouraged to apply.
