The Kacher Lab is currently looking for a dynamic researcher to aid in our efforts to understand the multiscale microstructural effects dictating the mechanical behavior of materials. As a team, we explore how microstructure and processing conditions affect bulk properties and local failure mechanisms using multiscale and in situ-based electron microscopy techniques. Currently, we are accepting applications for a post-doctoral position focused on understanding dislocation mechanics at the micro to nanoscale under a range of loading conditions. The work will involve in situ TEM using a custom-built quantitative micromechanical testing platform and post mortem analysis of dislocation/grain boundary interactions. The position is available beginning in August 2020 and will continue for one year from hire date, with yearly extensions to a second and third year possible depending on performance and funding.
Required Qualifications:
-
A Ph.D. in Materials Science and Engineering, Mechanical Engineering, Physics, or a related discipline.
-
Excellence in written and oral communication as evident by a strong publication and presentation track record.
-
Expertise in electron microscopy-based characterization
Desired Qualifications:
Strong candidates will have experience in at least some of the following areas:
- TEM-based dislocation characterization
- EBSD-based analysis of microstructure and defect structures
- FIB-based TEM sample preparation
- In situ TEM nanomechanical testing
- Fatigue testing and failure analysis
- Corrosion/stress corrosion cracking
Interested candidates should send a cover letter, CV including a list of publications and presentations, three potential references with phone numbers and emails included to Prof. Josh Kacher (josh.kacher@mse.gatech.edu). Reviews of applications will begin immediately and will continue until the position is filled.

Start date: September / October 2020
Locations: Grenoble (ESRF), Poitiers (PPrime), Paris (Ecole des Mines)
Understanding the deformation processes leading to the failure of polycrystalline structural materials is one of the key challenges in materials science. Significant progress has been achieved over the past decades, thanks to both cutting-edge experimental characterization techniques and computational methods. Still, the localization of plasticity in slip bands and the propagation of plasticity through a polycrystalline aggregate are not fully understood. The French ANR research project 3DiPolyPlast aims at improving our understanding of the multi-scale processes involved in plastic deformation by combining experimental observations with concomitant numerical simulation of strain localization. 3DiPolyPlast unites four leading research institutes covering the fields of X-ray characterization, electron microscopy and crystal plasticity modelling, respectively.

La Faculté des Sciences de Marseille propose deux postes d'Attaché Temporaire d'Enseignement et de Recherche (recrutement ATER).
1er recrutement ATER:
Sujet:
Comportement de films minces et de dispositifs de l'électronique souple sous sollicitation mécanique, élaboration de films minces thermoélectrique pour la récupération d'énergie.
Détails du poste:
La personne recrutée exercera ses activités de recherche prioritairement au sein de l'équipe MNO du département PHANO de l'IM2NP ou, à défaut au sein de l'équipe RDI du département MATER de l'IM2NP.
La personne recrutée développera des activités en science des matériaux avec une orientation tournée:
- Soit vers l'étude du comportement mécanique des films minces et des dispositifs de l'électronique ou du photovoltaïque (PV) flexible (équipe MNO), via principalement des expériences de diffraction des rayons X en rayonnement synchrotron (ESRF, SOLEIL, DELTA)
- Soit vers l'élaboration de films minces thermoélectriques non toxiques pour la récupération d'énergie dans les dispositifs microélectroniques (équipes RDI).
Plus d’information sur la durée du poste, la composante d'enseignement et les modalités d'application, sont disponibles dans le document téléchargeable suivant: « Fiche_de_poste_ATER_51831.pdf »
2nd recrutement ATER:
Sujet:
Imagerie de structure et de défauts dans des nano-objets sous sollicitation mécanique ou électrique.
Détails du poste:
La recherche portera sur l'étude de la structure (déformation, défauts,...) et des propriétés des nano-objets (nano-fils ou nano-plots) lorsqu'ils sont sous sollicitation, que se soit mécanique ou bien électrique. Pour cela nous utiliserons l'imagerie par diffraction cohérente des rayons-X en condition de Bragg (BCDI) ou bien l'imagerie à haute résolution par microscopie électronique en transmission (HR-MET).
la technique BCDI est une technique particulièrement novatrice qui permet de réaliser une image 3D des objets de petites tailles (quelques centaines de nm) pour révéler les variations de densité électronique et du champ de déplacement avec une résolution picométrique.
Par ailleurs, un nouveau porte-échantillon acquis récemment pour le MET à haute résolution TITAN à St Jérôme permet de sollicter électriquement des nano-objects et d'imager la déformation in situ.
De nombreuses données ont été collectées ces dernières années et des nouvelles expériences à l'ESRF et au TITAN sont prévues. L'analyse et la valorisation des ces expériences seront au centre de la recherche associé à ce poste.
Plus d’information sur la durée du poste, la composante d'enseignement et les modalités d'application, sont disponibles dans le document téléchargeable suivant: « Fiche_de_poste_ATER_56224.pdf »

The Department of Materials Science and Engineering of the Friedrich-Alexander-Universität (FAU) Erlangen-Nürnberg is inviting applications for three doctoral research positions to begin immediately.
Subject:
The successful applicants will work together with Prof. Erik Bitzek on studying the atomistic origins of materials failure in the context of:
(1) Semi-brittle fracture in the ERC-funded Project microKIc : Microscopic Origins of Fracture Toughness.
(2) Nanomechanics and small-scale plasticity within the research training group GRK 1896 “In Situ Microscopy with Electrons, X-rays and Scanning Probes".
(3) Properties of defects in complex intermetallic phases within the Collaborative Research Center SFB 1394 “Structural and Chemical Atomic Complexity: From Defect Phase Diagrams to Material Properties”.
Requirements:
Applicants should have a master’s degree with good to excellent marks in Physics, Material Science, Mechanical Engineering, Chemistry, or a related field. Experience in performing numerical simulations, preferably using Molecular Dynamics, and in scientific programming are advantageous. In addition, a solid background in mechanical behavior of materials, physical metallurgy and thermodynamics is highly desirable. Excellent oral and written communication skills and the ability to work well in a dynamic and collaborative research environment are essential.
Application:
The position is full-time, and payment follows the German TV-L 13 scale. The starting date is as soon as possible. The FAU Erlangen-Nürnberg intends to increase the number of women in research and teaching positions and, therefore, strongly encourages female researchers to apply. Disabled applicants will be preferentially considered in case of equivalent qualification.
Please send your application (including a cover letter describing your research interests, curriculum vitae, transcript of records as well as contact information of two references) to comp-mat-sci-jobs@ww.uni-erlangen.de.
