Paracelsian, $BaAl_{2}Si_{2}O_{8}$, under high pressure: three new phase transitions and three new high-pressure phases
XX Meeting of the International Mineralogical Association, MelbourneMelbourne, Australia, 13 Aug 2018 - 17 Aug 20182018-08-132018-08-17
Minerals of the feldspar group are the most common minerals in the Earth’s crust. Due to their high geological relevance, numerous X-ray diffraction studies at non-ambient conditions (high temperature (HT) and / or pressure (HP)) have been performed with detailed studies focused on orthoclase, sanidine, microcline, albite, and anorthite. [...]

Structural investigations of spider attachment hairs
Verhandlungen der Deutschen Physikalischen Gesellschaft e.V., BerlinBerlin, Germany, 11 Mar 2018 - 16 Mar 20182018-03-112018-03-16
The hairy attachment system of spiders enables these animals to walkupside-down on rough and smooth surfaces without the use of glue.These outstanding biological structures comprise of pads includinghundreds to thousands of specially designed hairs that are made ofcomposite materials consisting of proteins and reinforcing chitin fibres.The goal of our study is to gain an in-depth understanding of thestructure-function mechanism of the attachment and detachment processesof single hairs to a surface. X-ray Tomographic Microscopy andScanning X-ray nanobeam diffraction are ideal tools to reveal the innerstructure of the spider hairs and allow to determine the gradient of themechanical properties which is essential for the attachment process.With both techniques we found that the shaft of the attachment hairis hollow.

Searches for electroweak production of supersymmetric gauginos and sleptons with the ATLAS detector
25th International Conference on Supersymmetry and the unification of fundamental Interactions, SUSY17, Tata Institute of fundemental research,MumbaiTata Institute of fundemental research,Mumbai, India, 11 Dec 2017 - 15 Dec 20172017-12-112017-12-15
Many supersymmetric models feature gauginos and also sleptons withmasses less than a few hundred GeV. These can give rise to direct pairproduction rates at the LHC that can be observed in the data samplerecorded by the ATLAS detector [...]

Parton densities from a parton branching solution of QCD evolution equations
QCD@LHC 2017, QCD@LHC 2017, DebrecenDebrecen, Hungary, 28 Aug 2017 - 1 Sep 20172017-08-282017-09-01
QCD evolution equations can be recast in terms of parton branching processes. We present a newnumerical solution of the equations and show, that this method reproduces the semi-analytical solutions.We discuss numerical effects of the kinematic boundary of resolvable branchings on the resultingparton distribution functions.

Latest results on diffraction at HERA
6th International Conference on New Frontiers in Physics, ICNFP17, KolymbariKolymbari, Greece, 17 Aug 2017 - 26 Aug 20172017-08-172017-08-26
Recent results on diffraction from the H1 and ZEUS experiments at HERA are presented. Measurement of open charm production in diffractive DIS has been performed by the H1 experiment using the event topology, given by ep→eXY, where the system X, containing at least one D*(2010) meson, is separated from a leading low-mass proton dissociative system Y by a large rapidity gap.

In-situ Crystallization Cell: Developments and First Results of the Model System $Al(acac)_{3}$
18. Conference of the GDCh Division Solid State Chemistry and Materials Research, InnsbruckInnsbruck, Austria, 19 Sep 2016 - 21 Sep 20162016-09-192016-09-21
In-situ investigations of the crystallization of solids are still necessary for the understanding and the rational synthesis of precursors, intermediates and products with special or even improved properties.[1] With our crystallization cell,[2] the detection and the control of different reaction parameters during chemical reactions in fluid media can be achieved. The modifications of the cell allow in-situ experiments with X-ray diffraction (XRD).[2] The crystallization of Al(acac)3 (acac = acetylacetonate) as model system was investigated to demonstrate the performance of the cell.
