The experiment was performed at a temperature of 400 K under continuous gas flow conditions of pure Ar and Ar/CO mixtures.

For a protein in an aqueous environment, for instance, hydrogen bonds between the protein and surrounding water molecules strongly affect its folding and thereby also its function.

Thereby, limiting thenumber of degrees of freedom is critical for selective targeting and understanding of theunderlying processes [...] External link: Fulltext 2019-09-0509:45 [PUBDB-2019-03228] Journal Article et al Aerodynamically stabilized Taylor cone jets Physical review / E 100(3), 031101 (2019) [10.1103/PhysRevE.100.031101]   We introduce a way to stabilize steady micro/nanoliquid jets issuing from Taylor cones together with coflowing gas streams. We study the dripping-jetting transition of this configuration theoretically through a global stability analysis as a function of the governing parameters involved [...] OpenAccess: PDF PDF (PDFA); 2019-09-0310:50 [PUBDB-2019-03190] Contribution to a book Betzel, C. Megahertz serial crystallography Hamburg : DESY, Photon Science 2018 : Copy deadline: December 2018, 76 – 79 (2018) Barely two weeks after the European XFEL opened its doors to users, the first user experiment was performedby a DESY-led international team of over 120 researchers. The European XFEL is the first hard X-ray FEL in the world capable of producing femtosecond pulses at a megahertz repetition rate.

Cool chemistry with spatially separated molecular species Hamburg : DESY, Photon science 2018 : Copy deadline: December 2018, 64 – 65 (2018) Molecules are the entities defining the world around us, the building blocks of chemistry and biology. Everybody knows what a molecule is, but it’s far from trivial to define exactly what is a ‘molecule’ [...] 2019-09-0213:17 [PUBDB-2019-03171] Journal Article Hammad Mekky Koua, F. Structural changes in the acceptor site of photosystem II upon Ca$^{2+}$/Sr$^{2+}$ exchange in the Mn$_4$CaO$_5$ Cluster Site and the Possible Long-Range Interactions Biomolecules 9(8), 371 (2019) [10.3390/biom9080371]   The Mn4CaO5 cluster site in the oxygen-evolving complex (OEC) of photosystem II (PSII) undergoes structural perturbations, such as those induced by Ca$^{2+}$/Sr$^{2+}$ exchanges or Ca/Mn removal. These changes have been known to induce long-range positive shifts (between +30 and +150 mV) in the redox potential of the primary quinone electron acceptor plastoquinone A (QA), which is located 40 Å from the OEC.

However, mixed populations of these intermediates and moderate resolution limit the interpretation of the data from current experiments.

To process the data, the diffraction patterns must first be indexed, equivalent to determining the orientation of each crystal. [...] Fulltext: publ.
