Deconstructing complex assem-blies of paints horizontally across a picture and vertically through it provides insight into the detailed production process of the art work and on the painting techniques and styles of its maker.

Two-photon polymerization lithography is a mask-less technique with down to 100 nm resolution that provides full geometric freedom [...] OpenAccess: PDF PDF (PDFA); 2019-03-1113:10 [PUBDB-2019-01441] Journal Article et al Synchrotron-based crystal structure, associated morphology of snail and bivalve shells by X-ray diffraction Radiation physics and chemistry 127, 155 - 164 (2016) [10.1016/j.radphyschem.2016.06.024]   Synchrotron-based high-resolution X-ray powder diffraction spectra from the body parts of a snail and bivalve (CaCO$_3$), have been recorded with Pilatus area detector. Experiments were performed at Desy, Hamburg, Germany, utilizing the Resonant and Diffraction beamline (P9), with 15 keV X-rays (λ=0.82666 Å).

The thermodynamic stability of the premartensite phase and its relation to the martensitic phase is still an unresolved issue, even though it is critical to the understanding of the functional properties of MSMAs [...] OpenAccess: PDF PDF (PDFA); 2019-03-1111:56 [PUBDB-2019-01438] Journal Article Upadhyay, C. Magnetodielectric Relaxation in $Ho_{2}Ti_{2}O_{7}$ and $Dy_{2}Ti_{2}O_{7}$ Spin Ice Restricted: PDF PDF (PDFA); 2019-03-1111:39 [PUBDB-2019-01436] Journal Article et al Néel transition in the multiferroic $\mathrm{BiFeO_{3}-0.25PbTiO_{3}}$ nanoparticles with anomalous size effect Journal of applied physics 125(2), 024102 (2019) [10.1063/1.5052177]   The role of size reduction on the structural parameters, antiferromagnetic transition temperature (T$_N$), and spin reorientation transition temperature of BiFeO$_3$-0.25PbTiO$_3$ (BF-0.25PT) has been studied. Rietveld analysis using high resolution synchrotron x-ray powder diffraction data confirms that the space group of BF-0.25PT solid solutions is monoclinic Cc and not rhombohedral R3c for both bulk and nanocrystalline powders.

We use bulk sensitive hard x-ray photoelectron spectroscopy (HAXPES) and density functional theory based on the Green's function technique to demonstrate the importance of electron-electron correlations of both the Ni 3d (U$_{Ni}$) and Mn 3d (U$_{Mn}$) electrons in explaining the valence band of this multiply correlated material [...] OpenAccess: PDF PDF (PDFA); 2019-03-1111:18 [PUBDB-2019-01433] Journal Article et al “Sacrificial protection in action!”: ultra-high stability of palladesite mineral towards the oxygen reduction reaction Journal of materials chemistry / A 7(3), 979 - 984 (2019) [10.1039/C8TA10640A]   It is of the utmost importance to design an oxygen reduction electrocatalyst with high durability and good activity for large scale utilization in industry. Although several materials have been developed at the laboratory scale with extremely good activity, the durability of most of these materials is not sufficient enough to scale them up.
