Post-doctoral Fellowship in Heterogeneous Kinetics

**Discipline : CERI EE**

**Line Manager**: Emmanouil Romanias & Liselotte Tinel

**Location **:IMT NORD EUROPE, CERI EE, 941 rue Charles Bourseul, 59500 Douai

**Type of contract **:CDD, 36 months of recruitment as post-doc / research engineer.

**CONTEXT**:
Public establishment belonging to IMT (Institut Mines-Télécom), placed under the supervision of the Ministry of Economy, Finance and Industrial and Digital Sovereignty, IMT Nord Europe has three main objectives: providing our students with ethically responsible engineering practice enabling them to solve 21st century issues, carrying out our R&D activities leading to outstanding innovations and supporting territorial development through innovation and entrepreneurship. Ideally positioned at the heart of Europe, 1 hour away from Paris, 30 min from Brussels and 1h30 from London, IMT Nord Europe has strong ambitions to become a main actor of the current industrial transitions, digital and environmental, by combining education and research on engineering and digital technologies.

Located on two main campuses dedicated to research and education in Douai and Lille, IMT Nord Europe offers research facilities of almost 20,000m² in the following areas:

- Digital science,
- Energy and Environment,
- Materials and Processes.

The Centre for Education, Research and Innovation in Energy and Environment (CERI EE) of the IMT Nord Europe institute, is a research center employing around 80 people including 30 faculty members. The main research activities of CERI EE deals with experimental atmospheric chemistry and physics of outdoor and indoor environments, by means of laboratory studies and field measurements. The center has a significant expertise in the study of the degradation of pollutants in the gas and heterogeneous phases deploying photochemical reactors, atmospheric simulation chambers and indoor experimental rooms, as well as pollutant and particle monitoring in outdoor and indoor environments.** CERI EE is included **in the list of Shanghai with top universities/research centers working in atmospheric science domain. CERI EE is also European topical center unit for reactive trace gases in-situ measurement (**CiGas**) within **ACTRIS**, equipped with cutting edge instrumentation for air pollutant monitoring, particle characterization, and a unique expertise in analytical development and method evaluation. Furthermore, **CERI EE takes part in many regional and multidisciplinary projects related with air quality and climate change, e.g. Labex CaPPA, CPER CLIMIBIO, CPER ECRIN.

**Scientific scope of the post-doctoral fellowship**

Solid particles in the atmosphere are ubiquitous and their environmental impact is manifold. Solid particles influence the Earth’s climate directly by scattering and absorbing solar radiation, and indirectly by influencing cloud formation and lifetime. Besides, mineral dust, the largest mass fraction of solid particles globally, acts as an efficient platform for the scavenging or conversion of gases, thus providing a media to transport atmospheric compounds over long distances. Certain organic particles, such as microplastics, can also have very long atmospheric lifetimes and act as sinks or sources for gaseous species. These heterogeneous photochemical processes not only influence the burden of atmospheric species but also modify the physicochemical properties of particles, thereby affecting their corresponding impacts on climate. However, the fundamental processes of these reactions are not well understood and their impacts remain therefore difficult to evaluate.

The objective of this postdoctoral fellowship is to investigate the heterogeneous interactions/reactions of selected organic and inorganic pollutants with different types of solid particles: microplastics, natural mineral dust and individual components of mineralogical origin, such as mineral oxides. Laboratory experiments will be conducted in state-of-the-art reactors (coated wall flow tube reactor, packed-bed reactor, optical DRIFT cell, Knudsen cell,) to determine accurate kinetic parameters such as initial and steady-state uptake coefficients, as well as mechanistic parameters like product yields and reaction pathways, combining both the gas phase and the adsorbed phase.

**Objective of the position**
- Investigate heterogeneous processes between inorganic and organic compounds with bulk aerosol surfaces (e.g. microplastics, mineral dust, mineral oxides).
- Use advanced experimental tools for the study of heterogeneous kinetic processes such as flow tubes, atmospheric simulation chambers, Knudsen cell.
- Supervise PhD students, write progress reports.
- Present the results in international and national conferences and publish them in high level peer-review journals.

**Required qualifications**
- PhD in Chemistry, Physical Chemistry, Atmospheric Sciences or in relevant fields.
- Extensive and solid background in chemical kinetics, atmospheric photochemistry, and
