Chirality of structure and magnetism in the magnetoelectric compound Cu2OSeO3

Henrik Moodysson Rønnow, Arnaud Magrez, Jonathan White, Krunoslav Prsa, Ping Huang

Small-angle diffraction of polarized neutrons and resonant contribution to diffraction of synchrotron radiation have been applied to prove chirality of the crystal and magnetic structures of the magnetoelectric insulator Cu2OSeO3. Similarly to other chiral ...

Light Transport Matrix recovery for nearly planar objects

Martin Vetterli, Paolo Prandoni, Loïc Arnaud Baboulaz, Niranjan Thanikachalam

The light transport matrix has become a powerful tool for scene relighting, owing to the versatility of its representational power of various light transport phenomenon. We argue that scenes with an almost planar surface geometry, even with significant amo ...

Elastodynamics of a Two-Dimensional Square Lattice With Entrained Fluid-Part I: Comparison With Biot's Theory

Alessandro Spadoni, Vladimir Dorodnitsyn

In the present paper, the performance of Biot's theory is investigated for wave propagation in cellular and porous solids with entrained fluid for configurations with well-known drained (no fluid) mechanical properties. Cellular solids differ from porous s ...

Enhanced crystallinity in organic-inorganic lead halide perovskites on mesoporous TiO2 via disorder-order phase transition

Ulf Anders Hagfeldt

Organic-inorganic halide perovskite (OIHP) compounds are very interesting materials for device application in, for example, solar cells, electro-optics, and electronic circuits. In this report, we investigated OIHPs reported as CH3NH3PbI3-xClx (MAPbI 3-xCl ...

Up-scalable method to amplify the diffraction efficiency of simple gratings

Olivier Martin, Martin Stalder

An innovative class of coupling gratings for efficiently redirecting light beams is described. They are based on symmetric binary gratings equipped with an asymmetric high refractive index coating. This kind of structure exhibits a grating blaze effect and ...

Growth of Large and Highly Ordered 20 Crystals of a K+ Channel, Structural Role of Lipidic Environment

Henning Paul-Julius Stahlberg

2D crystallography has proven to be an excellent technique to determine the 3D structure of membrane proteins. Compared to 3D crystallography, it has the advantage of visualizing the protein in an environment closer to the native one. However, producing go ...

Simultaneous neutron transmission and diffraction contrast tomography as a non-destructive 3D method for bulk single crystal quality investigations

Steven Luc X Peetermans

Traditional neutron tomography allows to reconstruct the attenuation cross section, a measure for the material distribution, at high spatial resolution and non-destructively. However, it does not state anything about the ordering structure of the atoms ins ...

InAs1- xPx nanowires grown by catalyst-free molecular-beam epitaxy

Vasiliki Tileli

We report on the self-catalysed growth of vertical InAs1-xPx nanowires on Si(111) substrates by solid-source molecular-beam epitaxy. High-resolution transmission electron microscopy revealed the mixed wurtzite and zincblende structure of the nanowires. Ene ...

Powder crystallography of pharmaceutical materials by combined crystal structure prediction and solid-state H-1 NMR spectroscopy

David Lyndon Emsley

A protocol for the ab initio crystal structure determination of powdered solids at natural isotopic abundance by combining solid-state NMR spectroscopy, crystal structure prediction, and DFT chemical shift calculations was evaluated to determine the crysta ...

Electronic structure of Mg2Si by combining electron diffraction and first-principles calculations

Pierre Stadelmann

We have used accurate convergent beam electron diffraction to determine the structure factors of the reflections most sensitive to the valence-electron distribution in Mg2Si. The experimental values agree well with calculations of the structure factors bas ...
