The studentship is part of a funded project on refractive optics for X-ray wavefront correction being jointly undertaken by the University of Oxford (A.M. Korsunsky) and Diamond Light Source (K. Sawhney and D. Laundy).
Diamond Light Source (http://www.diamond.ac.uk) is the UK’s national synchrotron science facility. The facility provides intense beams of X-rays delivered along beamlines to diverse experiments. Specialised X-ray optical components are used to focus the X-rays into sub-micrometre focal spots to obtain high photon flux density and high spatial resolution at the sample. Currently the smallest X-ray spots achievable at Diamond are sub 100 nanometre. Achieving such small focused X-ray beams places great demands on the quality of the X-ray focusing optics. The Optics Group at Diamond are developing micro-fabricated refractive optical components to correct for the fabrication errors in X-ray focusing optical components with the potential to obtain X-ray focal spots sizes of less than 10 nanometre in size. This would be of great benefit to the cutting edge experiments performed at the synchrotron.
The successful applicant will participate in the design and fabrication of this novel X-ray optics; evaluation of the optics, in particular performing sensitive measurements to characterise the new optics on B16, the Test Beamline. At Oxford, the student will become a member of Prof. Korsunsky’s group (MBLEM).
Applications should be made directly to University of Oxford, details here.
Informal enquiries are encouraged and should be addressed to Professor Alexander Korsunsky (firstname.lastname@example.org).

- Contact details for two academic or professional referees
Start in October 2017.
Application deadline: Friday 28th July, 2017, Interviews will be held in mid-August, 2017.
The last decade has seen a tremendous evolution of X-ray imaging and microscopy. This has been driven by the rapid development of third and fourth generation X-ray facilities and X-ray optics capable of producing coherent beams routinely below 100 nm in size. The high penetrating power, extreme sensitivity of X-rays to strain and defects and the tunability of these new sources to access X-ray fluorescence of much of the periodic table has enabled in situ or operando studies of nano-scale properties materials. It is worth also emphasizing that small X-ray beams may also be used to induce an electrical current or light emission in the nano-object enabling enhanced scanning probe and photo excitation studies.
Beyond a discussion of the methods which have been developed, and are still an object of active research (coherent diffraction imaging in forward or Bragg conditions, nano X-ray fluorescence imaging, micro-Laue diffraction …), this symposium aims to disseminate knowledge of these new tools to a broader community of materials scientists.
Call for Papers:
Abstract submission opens: September 29th 2017.

This symposium is intended as an international forum for the presentation and discussion of the latest scientific developments regarding the physics and mechanics of fracture. Rather than addressing specific engineering problems and approaches, this symposium will cover fracture of brittle and semi-brittle materials at a fundamental level, with a focus on crack nucleation and crack-microstructure interactions. We aim at bringing together specialists from the fields of solid state physics, materials science, continuum mechanics, statistical physics and mathematics to cover theory, multi-scale modeling and experiments related to
• Initiation of fracture and crack nucleation
• Grain boundary fracture and interface cracks
• Crack – obstacle interactions
• Interplay of fracture and plasticity
• Fracture of nanostructures and disordered materials
• Fracture of composites
• Statistical aspects of fracture
• Micromechanical and local approaches to fracture
A special joint session on advanced micro- and nanomechanical fracture testing methods is envisaged with the planned EPS mini-colloquium »Mechanical properties at small scales« organized by Gerhard Dehm, Olivier Thomas and Laurent Pizzagalli.
The conference will take place at the Technische Universität Berlin.
Conference fee :
Students: 100/130 €
Regular Participant: 220/250 €
Reductions for DPG-Members
Deadline for abstract submission : 01.12.2017

Subject: OkMC simulations of dislocation loop evolution in presence of dislocation lines in Fe/FeCr under irradiation.
The objective of this PhD is to simulate the evolution of defects in structural materials (stainless steels) such as Fe/FeCr under neutron and ion irradiation in order to evaluate the number and types of defects that interact with dislocation lines, which can lead to hardening of the material. Simulations will be mainly performed with the recently developed (at CIEMAT) code Object kinetic Monte Carlo based on GPU programming. This work will be carried out in the framework of the European H2020 project M4F (Multiscale modeling for fusion and fission materials), that will start in September 2017.
Required skills: Good background in C++ programming. Knowledge of CUDA programming will be highly appreciated. And a strong motivation!
If you are interested, please contact Dr. Christophe Ortiz (firstname.lastname@example.org).

The work will be focused on microstructural characterization and nanotribology experiments applying advanced micromechanical experiments (wear experiments, in-situ micro-mechanical testing) and characterization methods (scanning electron microscopy, focused ion beam microscopy and atom force microscopy).
Applications exclusively via email to email@example.com .
Please include a letter of motivation, a CV, if existing, a list of publications and up to two letters of recommendation. Applications will be accepted until a candidate is found.
