Job Title: Junior Postdoc-Electrocatalysis; in situ electron microscopy characterization; deep learning frameworks for TEM image analysis​​

Department: Advanced Electron Nanoscopy

Description of Group/Project:

We are looking for a junior postdoc to support advanced characterization efforts within the framework of the IMPRESS project, a European initiative  finvolving international partners. This project aims to tackle the global challenge of reducing greenhouse gas emissions by developing innovative, sustainable energy solutions, specifically through the generation of green hydrogen via solar-driven photoelectrochemical (PEC) systems. In this position, you will apply advanced electron microscopy techniques, including STEM to investigate the structure and behavior of catalytic nanomaterials critical for green hydrogen and energy technologies. The candidate will design and perform real-time in-situ TEM experiments using gas and liquid sample environments, enabling the observation of materials under conditions that mimic actual operating environments. Working closely with partners in the IMPRESS project, you will analyze their materials and provide valuable insights to help optimize device performance. Additionally, you will support collaborators by assisting with in-situ TEM measurements, facilitating cutting-edge research in sustainability and energy fields. Part of the project will also include the development of deep learning frameworks for TEM image analysis.         

Main Tasks and responsibilities:

The main tasks would be:

·          Operate and optimize advanced STEM and FIB instrumentation for the nanoscale analysis of catalytic and energy-related nanomaterials, supporting the development of high-performance materials for green hydrogen production and energy storage.

·          Perform detailed STEM analyses on project-related materials provided by IMPRESS partners, contributing directly to the evaluation and development of novel PEC systems.

·          Design and implement in-situ TEM experiments using the available gas and liquid sample holders to study dynamic processes in real-time, under controlled environmental conditions relevant to catalysis and PEC operation.

·          Work closely with national and international collaborators by offering hands-on support and guidance for in-situ TEM experiments.

·          Train students and other researchers on in-situ (S)TEM.

AVAILABLE INSTRUMENTS

·          Thermo Fisher Spectra 300 (60-300 keV), double corrected and monochromated, Gatan Continuum EELS with K3 direct electron detector, segmented and pixelated detectors, Super-X EDS system.

·          Thermo Fisher Spectra ULTRA (30-300 keV), double corrected and monochromated, HR EELS, segmented and pixelated detectors, ULTRA-X EDS system.

·          Cooling, heating and biasing DENSsolutions ARCTIC sample holder

·          Liquid, biasing DENSsolutions STREAM sample holder

·          Gas/Vapour, heating/biasing DENSsolutions CLIMATE sample holder

·          FEI F20 200 KeV STEM, EELS + EDX

·          Fully Automated FIB Helios 5UX

·          FEI SEM Quanta and SEM Magellan

Requirements:

• Education: PhD in Physics, Materials Science, Nanoscience, Computer Engineering, Data Science.
• Knowledge: Deep expertise in electron microscopy, particularly STEM and EELS methods. Proven experience in designing and conducting in-situ TEM experiments. Familiarity with energy-related nanomaterials and catalysis is highly desirable.
• Professional Experience: Previous research experience in an academic or industrial setting involving advanced transmission electron microscopy for energy materials or catalysis, skills on in-situ TEM and AI ML/DL coding skills will be a plus. Experience collaborating in international, multidisciplinary projects is a plus. Hands-on experience working with large-scale research infrastructures, such as synchrotrons, is an advantage.
• Personal Competences: Strong problem-solving skills and the ability to work independently as well as part of a collaborative international team. Excellent communication skills to support project partners effectively and contribute to scientific discussions and reporting. Adaptability, attention to detail, and a proactive attitude toward research challenges are essential for success in this position.

Summary of conditions:

• Full time work (37,5h/week)
• Contract Length: Temporary
• Location: Bellaterra (Barcelona)
• Salary will depend on qualifications and demonstrated experience.
• Support to the relocation issues.
• Life Insurance.
