 2018-03-0511:59 [PUBDB-2018-01373] Journal Article et al An investigation on shear banding and crystallographic texture of Ag–Cu alloys deformed by high-pressure torsion 2018-03-0115:02 [PUBDB-2018-01352] Journal Article et al Picometer polar atomic displacements in strontium titanate determined by resonant X-ray diffraction Nature Communications 9(1), 178 (2018) [10.1038/s41467-017-02599-6]   Physical properties of crystalline materials often manifest themselves as atomic displacements either away from symmetry positions or driven by external fields. Especially the origin of multiferroic or magnetoelectric effects may be hard to ascertain as the related displacements can reach the detection limit [...] OpenAccess: PDF PDF (PDFA); 2018-01-2212:32 [PUBDB-2018-00717] Journal Article et al Raman and fluorescence contributions to the resonant inelastic soft x-ray scattering on $LaAlO_{3}/SrTiO_3$ heterostructures Physical review / B 97(3), 035110 (2018) [10.1103/PhysRevB.97.035110]   We present a detailed study of the Ti $3d$ carriers at the interface of $LaAlO_{3}/SrTiO_3$ heterostructures by high-resolution resonant inelastic soft x-ray scattering (RIXS), with special focus on the roles of overlayer thickness and oxygen vacancies. Our measurements show the existence of interfacial Ti $3d$ electrons already below the critical thickness for conductivity [...] OpenAccess: PDF PDF (PDFA); 2018-01-1211:04 [PUBDB-2018-00603] Journal Article et al Characterization of $\mathrm{A^{III}B^V}$ superlattices by means of synchrotron diffraction topography and high-resolution X-ray diffraction Journal of applied crystallography 50(4), 1192 - 1199 (2017) [10.1107/S1600576717008846]   New possibilities are presented for the characterization of A$^{III}$B$^V$ mixed superlattice compounds by the complementary use of synchrotron diffraction topography and rocking curves. In particular, using a synchrotron white beam and the section diffraction pattern of a 5 µm slit taken at a 10 cm film-to-crystal distance, it was possible to reproduce a set of stripes corresponding to interference fringes.

Structural insight into the interacting surfaces is a prerequisite to understand the interaction characteristics as well as the underlying physical mechanisms. [...] Published on 2017-02-09. Available in OpenAccess from 2018-02-09.: PDF PDF (PDFA); Restricted: PDF PDF (PDFA); 2018-01-1117:09 [PUBDB-2018-00569] Journal Article et al pH-sensitive N,N-(dimethyl)-N-alkanamine-N-oxides as gene delivery vectors Chemical papers 71(9), 1739 - 1748 (2017) [10.1007/s11696-017-0171-2]   N,N-(Dimethyl)-N-alkanamine-N-oxides C$_n$NO (n = 12 and 16) are amphiphiles that exist in neutral as well as in cationic forms depending on pH of aqueous solutions. C$_n$NO with a neutral lipid DOPE (dioleoylphosphatidylethanolamine) can form liposomes with positive surface charge in acidic pH solution.

Nano-polycrystalline stishovite, recently synthesized from Earth-abundant silica glass, proved to be a super-hard, ultra-tough material, which could provide sustainable supply of high-performance ceramics.

In order to identify other toughening mechanisms which may operate simultaneously, we evaluated effect of crack deflection on fracture toughness.

Brannerite content in the ceramics ranged between ∼20 and 90 vol.%.

In the CRVO structure, the RE atoms are known to share the site occupation with Ca atoms at two or three among four Ca sites, with partial occupancy values depending on the choice of the RE atom.
