The compressional behaviour of a natural allanite from Lago della Vecchia (upper Cervo valley, Italy) metagranitoids[A1(Ca0.69Fe2+0.31)Σ1.00A2(Ca0.46Ce0.24La0.12Sm0.02Pr0.05Nd0.09Th0.02)Σ1.00M1(Al0.65Fe3+0.34Ti0.02)Σ1.01M2(Al0.99)M3(Fe3+0.54Fe2+0.36Mg0.06Ti4+0.02Al0.01)Σ0.99 Si1,Si2,Si3(Si2.80Al0.20)Σ3.00O11(OH,O)] has been investigated up to 16 GPa (at 298 K) by means of in situsynchrotron single-crystal X-ray diffraction. Experiments have been conducted under hydrostatic conditions, using a diamondanvil cell and the mix methanol:ethanol:water = 16:3:1 (up to 10 GPa) and neon (up to 16 GPa) as pressure-transmittingmedia.

As many metals are essential for plants, excess or deficiency of them or alteration of their uptake, translocation, sequestration or physiological use can have severe consequences for plant growth and fitness. Therefore, investigating the distribution and speciation of metals in tissues is essential to understand plant physiology. [...]

Objectives: Our first objective was to review the evidence describing the appearance and microstructure of theneonatal line in human deciduous teeth and to link this with known changes in neonatal physiology occurring atand around birth. A second objective was to explore ways to improve identification of the neonatal line bymapping the pre- and postnatal distribution of Ca, Sr and Zn in deciduous cuspal enamel and superimposingthese maps onto transmitted light micrographs that included a clear true section of the neonatal line.Materials and methods: We used synchrotron X-ray fluorescence to map elemental distributions in pre- andpostnatal enamel and dentine.

A fossil Cenozoic late instar strepsipteran larva is described and evaluated phylogenetically. The single specimen is embedded in Eocene Baltic amber. [...]

A new measurement protocol was used for microscopic chemical analysis of surface oxide films with lateral resolution of 1 μm.The native air-formed oxide and an anodic passive film on austenite and ferrite phases of a 25Cr-7Ni super duplex stainless steelwere investigated using synchrotron hard X-ray photoemission electron microscopy (HAXPEEM). Pre-deposited Pt-markers, incombination with electron backscattering diffraction mapping (EBSD), allowed analysis of the native oxide on individual grains ofthe two phases and the passive film formed on the same area after electrochemical polarization of the sample.

Photoprocesses of the endohedral fullerene ions Sc$_3$N@C$_{80}^+$ and Sc$_3$N@C$_{80}^-$ in the gas phase have been investigated in the photon energy ranges 30--50 eV and 280--420 eV. Single and double ionization as well as single ionization accompanied by the release of a C$_2$ dimer were observed as a function of the photon energy for the positive parent ion and double detachment was measured for the negative parent ion. [...]

We present a lattice QCD spectroscopy study in the isospin singlet, strangeness $-2$ sectors relevant for the conjectured $H$ dibaryon. We employ both hexaquark and two-baryon interpolating operators to isolate the ground state in the rest frame and in moving frames. [...]
