Missions

The study of superheavy nuclei makes use of special beams and targets, the preparation of which requires a to associate disciplinary excellence of physicists and chemists. The IPHC is currently the reference laboratory for the synthesis of MIVOC compounds for the production of heavy metal beams for nuclear physics. For example, the isotopic 50Ti and 54Cr organometallic compounds prepared by the IPHC are used in experiments to produce a new atomic element Z=120 at Dubna (Russia). The isotopic compounds for experiments at the Grand Accélérateur National d'Ions Lourds (GANIL) in Caen are also prepared by our team. The success of this scientific research theme is the result of multidisciplinary collaboration conducted at international level.
The candidate will be in charge of the synthesis of MIVOC compounds for experiments conducted by IN2P3 researchers and their collaborations. He/she will be particularly involved in the development of new MIVOC compounds, with a focus on the magnesium, selenium, thorium, uranium and zinc elements discussed in the framework of the IN2P3 Stable Beam Master Project. He/she will also perform syntheses of MIVOC isotopic compounds for which synthesis protocols have already been established. In view of the cost of these highly enriched isotopic compounds, special attention will also be given to the development of protocols for the separation of isotopic synthetic residues, in particular based on ion exchange resins, in order to be able to recycle as much of these elements as possible. Developments in high-temperature methods have also led the team to produce isotopic metal pellets. The researcher will work to improve our protocols for preparing these samples in close collaboration with other MIVOC members.
The researcher will develop the synthesis of new molecules based on transition elements and/or lanthanide ions in close collaboration with the other members of the SynPA team. This part of the project will focus on new luminescent probes capable of generating an upward conversion of photons into solution, for which the team is currently one of the world leaders (Nature Commun. 2016, 7:11978; J. Am. Chem. Soc. 2017,139, 1456, J. Am. Chem. Soc. 2019, 141, 1568).

Activities

- participate in the "stable beams" master projet of the IN2P3,
- propose, when he/she deems it necessary, instrumental developments
- present his/her research through the publication of scientific and communication articles at national and international congresses.

Skills

Candidates must have a PhD in the field of organic chemistry,
He/she must have strong skills
- in organic synthesis,
- coordination chemistry and NMR and luminescence spectroscopy
- in high temperature reactions (calcination, chlorination or reduction)

The candidate must have a good knowledge of
- conventional methods of characterization
- synthesis techniques in an inert atmosphere
- techniques for purification of unstable compounds in air
- separation methods using ion-exchange resins

The candidate must:
- Good skills in scientific communication (fluent oral and written scientific English),
- Have at least 2 articles published as first author, including at least 1 in the field of the proposed position.
- Demonstrate autonomy
- Have good skills to work in an international collaboration (contributions to a collective project, meetings and missions outside the laboratory)

Work Context

The IPHC is a laboratory that combines disciplinary and multidisciplinary excellence with research and development conducted by its teams at the international level. The proposed post-doctoral program includes complementary activities in close partnership with two research teams:
- Team "From nuclei to the stars" (DNE) - Department of Subatomic Research (DRS)
Head. Benoît GALL
The team "from the nucleus to the stars" (DNE) is a group of experimental physicists who study stellar nuclear reactions, reaction mechanisms, perform spectroscopy of exotic nuclei and search for new isotopes or superheavy elements, and make spectroscopy when possible. The DNE Group also has a long tradition of instrumental developments.
- Team "Synthesis Analysis Team" (SynPA) - Department of Analytical Sciences (DSA)
Head. Loïc CHARBONNIERE
Synthesis Analysis Team (SynPA) is specialized in the synthesis of ligands and their use in coordination chemistry and organometallic chemistry. One of the main focuses of the team is to develop the synthesis of MIVOC compounds (volatile organometallic compounds), the other topics being dedicated to the use of complexes for imaging (MRI, microscopy, PET and SPECT).

Sharing working time is allocated equally between the two teams, with possible variations depending on service requirements or experimental activities.

Constraints and risks

He/she will have to perform his/her work in partners labs in France and abroad (Russia, Finland and Japan), according to the needs of the experiments. Duration as required for project progress (from 1 week to 1 month).

Additional Information

The application must include the following documents:
• A letter of motivation
• A detailed CV, with references internships or projects
• The pdf files of his two articles in first author that he will consider the most appropriate.
• Academic results of Master's years (for completed semesters)
• Letters of recommendation sent directly by referrals (not mandatory)

Desired experience: less than two years after the thesis
