|Intitulé du poste :||Post-doc in crystal growth : Crystal growth from a substrate to the bulk|
|Laboratoire/Institut :||Université Libre de Bruxelles – Free University of Brussel|
|Description du poste :||Geerts group works on crystal engineering and crystallization of molecular materials in specific conditions to control thin film structure and ultimately optoelectronic properties. See http://www.ulb.ac.be/sciences/chimpoly
Summary of “2Dto3D” research project: The occurrence of polymorphism is ubiquitous to various classes of organic compounds. Examples of polymorphism are known in numerous application fields, such as food, explosives, pigments, semiconductors, fertilizers, and pharmaceutical drugs. Polymorphs exhibit sometimes very different physical properties, chemical reactivity, and biological functions. Understanding and controlling polymorphism is therefore very important. Simple questions, such as “How many polymorphs has a given compound?” or “What drives polymorph selection?” remain unanswered yet. In this scientific context, scientists have started to explore the occurrence of substrate-induced polymorphism, i.e. the formation of polymorphs that exist only near solid substrates. In particular, 2Dto3D has the ambition to elucidate how positional and orientational order of molecules propagate from the substrate to the upper crystal layers. Epitaxy and absence of epitaxy are both considered. Chiral symmetry breaking is also used as a tool. In this manner, 2Dto3D will gain a fundamental understanding of polymorphism at the interface with solid substrates. For a recent review see: “Substrate-Induced and Thin-Film Phases: Polymorphism of Organic Materials on Surfaces” A. Jones et al. Adv. Funct. Mater. 2016, 26, 2233.
Candidate: A talented highly motivated young chemist or physicist with a Ph.D. in the field of crystal growth of organic molecules is actively searched. The candidate must have a sound knowledge of crystal structures, and diffraction methods. He/she must be hard at work, easy-going, rigorous, and have strong laboratory skills. He/she must be fluent in English and be able to write high-quality publications.
The position is for an initial duration of one year and could be extended upon mutual agreement.
To apply, candidates must send to Prof. Yves Geerts, a curriculum vitae, a letter explaining his/her motivations, a list of publications, and the name and email address of three reference persons. There is no application deadline. The position will be filled in as soon as possible.

Job Posting Title
Senior R&D Staff – SANS Instrument Scientist / NB50693637
End Posting Date
The Neutron Sciences Directorate (NScD) at Oak Ridge National Laboratory (ORNL) operates the High Flux Isotope Reactor
(HFIR), the United States’ highest flux reactor-based neutron source, and the Spallation Neutron Source (SNS), the world’s
most intense pulsed accelerator-based neutron source. Within this directorate, the Neutron Scattering Division (NSD)
operates the 30 instruments for neutron scattering research, studying a diverse range of materials using elastic and inelastic
neutron scattering, small angle neutron scattering (SANS), neutron reflectometry and neutron imaging techniques. Each year,
more than 1,000 experiments are carried out at HFIR and SNS in the physical, chemical, materials, biological and medical
sciences. Scientific research areas include quantum materials, soft matter and polymers, catalysis and interfacial chemistry,
materials and engineering, biological materials and systems and applications of computing, modeling and data analytics to
analysis of neutron scattering data. HFIR also provides unique facilities for isotope production and neutron irradiation. To

The Large Scale Structures Group of the Neutron Science Directorate (NScD) at Oak Ridge National Laboratory is seeking
an outstanding candidate as an Instrument Scientist who can participate on an SANS instrument team and build a robust
science user program. We are seeking candidates who are self-motivated, and have good interpersonal communication and
presentation skills. You should also demonstrate an ability to interact effectively with research staff at all levels, and to work
within a multidisciplinary team.
* Participate in user support, instrument development, and research activities at HFIR and/or SNS SANS instruments.
* Assist users as a local contact for experimental setup, data acquisition, user education as appropriate and will ensure
users are provided with analyzable data.
* Champion developments of neutron scattering instrumentation with various biological and/or soft condensed matter
characterization tools in order to further develop the user program in SANS at ORNL.
* Develop a high-quality personal research program that is well aligned with the mission of the NScD and exploit the myriad
of experimental opportunities at ORNL.
* Publish research results in scientific journals, maintain a strong commitment to the implementation of ORNL values and
ethics and ensure compliance with environmental, safety, health and quality program requirements.
* Ph.D. in Biollogy, Physics, Mathematics, Chemistry, Materials Science or related fields
* 5 or more years of experience with X-ray or neutron scattering post Ph.D
* Demonstrated ability to communicate research results in peer-reviewed publications.
* Demonstrated ability to work in a team environment tackling complex problems.
* Knowledge about the structure of biological and/or soft condensed matter is a distinct advantage.
* 6 or more years of relevant scattering experience.
* A track record of successful user support at a neutron or x-ray scattering facility is a distinct advantage.
* Ph.D.-level or post-doctoral experience at a neutron scattering or synchrotron facility is desired.
* Demonstrated ability to work with graduate students, post docs and other research scientists from academia and industry.
* Demonstrated ability to work with support and technical groups to advance sample environment, or data reduction or
analysis of SANS data.
