Vos missions en quelques mots
PhD Context and Scientific Challenge:
Institute Mines Telecom Nord Europe has a large experience on the development and characterization of gas sensors (ammonia, hydrogen sulphide, formaldehyde, etc…) for outdoor/indoor/industrial air quality monitoring and biomedical applications.
Organophosphorus compounds constitute a family of chemicals widely used in agricultural, industrial, and military applications. Highly toxic with a potential impact on human health and the environment, they make the development of rapid, sensitive, and cost-effective detection technologies essential.
Chemiresistive sensors are a promising alternative due to their simple architecture, low power consumption, and potential integration into portable devices. IMT NE group is specialized in conducting polymers (CPs)-based chemiresistors. CPs exhibit some interesting properties, including tuneable conductivity, sensitivity to chemical interactions, and compatibility with low-temperature fabrication processes. However, CPs alone are not adapted for OPs sensing and their combination with organic and inorganic materials is necessary.
Recent researches have shown that carbon dots (CDs), a 0-dimensional carbon nanomaterial, improved gas sensing performances of (semi-)conductive materials for fluorescent sensors and chemiresistors. CDs have several advantages over inorganic semiconducting materials, such as low toxicity, low cost, ease of manufacture, and abundant active sites. More importantly, their functionalization (-COOH, -N, -S) could provide additional surface-active sites to capture OPs through the hydrogen bonds interactions and surface functional groups.
Combining CPs with CDs opens new opportunities to improve sensor sensitivity, selectivity, and stability through the unique electronic and surface properties of these nanomaterials.
Furthermore, the environmental challenges associated with the manufacturing of electronic devices now require the development of greener ink formulations and processing to reduce the use of hazardous solvents and minimise the environmental footprint of the fabricated sensors.
This PhD project is positioned within this framework and aims to develop a new generation of high-performance chemiresistive sensors based on hybrid CPs:CDs materials fabricated using environmentally friendly processing approaches.

Descriptif du service
The PhD position is available within the CERI EE (https://recherche.imt-nord-europe.fr/energie-environnement-ceri/), in the "Observations, Sources and Atmospheric Processes" (OSPA) research area. Research conducted within OSPA focuses on the physicochemical properties of trace elements in ambient air and their applications. The objective is to better understand the formation and transformation processes of air pollutants and to propose solutions tailored to the needs of society and economic operators. The team's core research themes aim for a better understanding of the physicochemical processes of formation and reaction of gaseous and particulate pollutants and an assessment of their impact on humans and the environment.
This PhD position fall into the framework of a starting academic collaboration between the CERI EE , principal investigator Dr Alberto GREGORI, and the Consiglio Nazionale delle Ricerche SCITEC (https://www.scitec.cnr.it/en/) with Dr Mariacecilia PASINI and Dr Benedetta M. SQUEO. In the framework of this collaboration, a research period in the POP Lab in Milan (Italy) will be possible and encouraged.
