Upon decompression, the high pressure crystalline phaseremains almost unchanged until it transforms to the liquid state at around 2.3 GPa.

We elucidate details of the magnetic structure, showing the ratio of ellipticity of the spin helix is larger than previously thought, at 2.58(3), and reveal both a right-handed chirality and an out-of-plane component of the magnetic moments in the spin helix.

In particular, submonolayer and nanogranular systems expose highly interesting electrical, plasmonic, and catalytic properties.

Recently, there has been a high demand for harder and tougher optical windows that are able to endure severe conditions [...] OpenAccess: PDF; 2017-03-2111:50 [PUBDB-2017-01428] Journal Article Roth, S. V. Study of pattern transition in nanopatterned Si(100) produced by impurity-assisted low-energy ion-beam erosion Applied physics / A 123(4), 225 (2017) [10.1007/s00339-017-0756-1]   In this work, formation of self-organized Si nanostructures induced by pure Fe incorporation during normal incidence low-energy (1keV) Ar$^{+}$ ion bombardment is presented. It has been observed that the incorporation of Fe affects the evolution of the surface topography [...] Restricted: PDF; 2017-03-1509:30 [PUBDB-2017-01375] Journal Article et al Opening a nodal gap by fluctuating spin-density wave in lightly doped La$_{2−x}$Sr$_x$CuO$_4$ Physical review / B 95(10), 104512 (2017) [10.1103/PhysRevB.95.104512]   We investigate whether the spin or charge degrees of freedom are responsible for the nodal gap in underdoped cuprates by performing inelastic neutron scattering and x-ray diffraction measurements on La$_{2−x}$Sr$_x$CuO$_4$, which is on the edge of the antiferromagnetic phase. We found that a fluctuating incommensurate spin-density wave (SDW) with a bottom part of an hourglass dispersion exists even in this magnetic sample [...] OpenAccess: PDF; 2017-03-1313:36 [PUBDB-2017-01362] Journal Article et al Application toward Confocal Full-Field Microscopic X-ray Absorption Near Edge Structure Spectroscopy Analytical chemistry 89(3), 2123 - 2130 (2017) [10.1021/acs.analchem.6b04828]   Using X-ray absorption near edge structure (XANES) spectroscopy, information on the local chemical structure and oxidation state of an element of interest can be acquired. Conventionally, this information can be obtained in a spatially resolved manner by scanning a sample through a focused X-ray beam [...] 2017-03-1313:28 [PUBDB-2017-01361] Journal Article et al Simplex Volume Maximization (SiVM): A matrix factorization algorithm with non-negative constrains and low computing demands for the interpretation of full spectral X-ray fluorescence imaging data Microchemical journal 132, 179 - 184 (2017) [10.1016/j.microc.2017.02.001]   Technological progress allows for an ever-faster acquisition of hyperspectral data, challenging the users to keep up with interpreting the recorded data. Matrix Factorization, the representation of data sets by bases (or loads) and coefficient (or score) images is long used to support the interpretation of complex data sets. [...] Restricted: PDF;
