In-situ Laue diffraction on deforming micropillars

Single crystal deformation unveiling the characteristics of crystal glide and the role of defect propagation herein has been a matter of intense research more than 60 years ago. A manifold of different mechanical testing methods and crystal qualities were ...

EPFL2009

X-ray diffraction (XRD) techniques are widely used in determining crystallographic orientations. In this paper we describe a two-step method to determine the three-dimensional orientations of ferroelectric single crystals based on an improved rotating orie ...

Off-axis texture in nanostructured Ti1-xAlxN thin films

Alireza Karimi

Standard theta-2 theta and pole figure X-ray diffraction techniques were used to study structural properties and preferred orientation of nanostructured TiAIN thin films prepared using cathodic are deposition. Systematic collection of reflections from latt ...

Crystallization and halide phasing of the C-terminal domain of human KIN17

Here, the crystallization and initial phasing of the C-terminal domain of human KIN17, a 45 kDa protein mainly expressed in response to ionizing radiation and overexpressed in certain tumour cell lines, are reported. Crystals diffracting to 1.4 Å resolutio ...

Grain interactions in crystal plasticity

William Curtin

The plastic response of a sheet metal is governed by the collective response of the underlying grains. Intragranular plasticity depends on intrinsic variables such as crystallographic orientation and on extrinsic variables such as grain interactions; howev ...

Identification of nano-phases: relative merit of local analysis techniques (HRTEM, nanodiffraction, EDS/EELS)

Philippe Buffat

Information for phase identification may be gathered in the electron transmission microscope with spatial resolution down to the nanometre scale. Energy dispersive X-ray and electron energy loss spectrometries are based on inelastic electron/sample interac ...

Urotropin azelate: a rather unwilling co-crystal

Gervais Chapuis, Kurt Schenk

Urotropin (U) and azelaic acid (AA) form 1:1 co-crystals (UA) that give rise to a rather complex diffraction pattern, the main features of which are diffuse rods and bands in addition to the Bragg reflections. UA is characterized by solvent inclusions, par ...

Crystallographic excursion in superspace

Gervais Chapuis

After studying more than 100 different samples of calaverite Au1-pAgpTe2 (p 2CO3 resisted any attempt for a precise structural analysis. The appearance of satellite reflections was noted on single crystal diffractograms which led to the generalisation of t ...
