• Why productive lakes are larger mercury sedimentary sinks than oligotrophic brown water lakes 

  Schütze, Martin; Gatz, Philipp; Gilfedder, Benjamin‐Silas; Biester, Harald (Limnology and Oceanography, 2020-12-25)

  Abstract Mercury accumulation in lake sediments is a widespread environmental problem due to the biomagnification of Hg in the aquatic food chain. Soil Hg concentrations, catchment vegetation, erosion, and lake productivity ...

• The polymict carbonaceous breccia Aguas Zarcas: A potential analog to samples being returned by the OSIRIS‐REx and Hayabusa2 missions 

  Kerraouch, Imene; Bischoff, Addi; Zolensky, Michael E.; Pack, Andreas; Patzek, Markus; Hanna, Romy D.; Fries, Marc D.; Harries, Dennis; Kebukawa, Yoko; Le, Loan; Ito, Motoo; Rahman, Zia (Meteoritics & Planetary Science, 2021-02-02)

  Abstract On April 23, 2019, a meteorite fall occurred in Aguas Zarcas, Costa Rica. According to the Meteoritical Bulletin, Aguas Zarcas is a brecciated CM2 chondrite dominated by two lithologies. Our X‐ray computed tomography ...

• Petrogenesis of main group pallasite meteorites based on relationships among texture, mineralogy, and geochemistry 

  McKibbin, Seann J.; Pittarello, Lidia; Makarona, Christina; Hamann, Christopher; Hecht, Lutz; Chernonozhkin, Stepan M.; Goderis, Steven; Claeys, Philippe (Meteoritics & Planetary Science, 2019-09-29)

  Abstract Main group pallasite meteorites are samples of a single early magmatic planetesimal, dominated by metal and olivine but containing accessory chromite, sulfide, phosphide, phosphates, and rare phosphoran olivine. ...

• XGANDALF – extended gradient descent algorithm for lattice finding 

  Gevorkov, Yaroslav; Yefanov, Oleksandr; Barty, Anton; White, Thomas A.; Mariani, Valerio; Brehm, Wolfgang; Tolstikova, Aleksandra; Grigat, Rolf-Rainer; Chapman, Henry N. (Acta Crystallographica Section A, 2019-08-30)

  Serial crystallography records still diffraction patterns from single, randomly oriented crystals, then merges data from hundreds or thousands of them to form a complete data set. To process the data, the diffraction ...

• pinkIndexer – a universal indexer for pink‐beam X‐ray and electron diffraction snapshots 

  Gevorkov, Yaroslav; Barty, Anton; Brehm, Wolfgang; White, Thomas A.; Tolstikova, Aleksandra; Wiedorn, Max O.; Meents, Alke; Grigat, Rolf-Rainer; Chapman, Henry N.; Yefanov, Oleksandr (Acta Crystallographica Section A, 2020-01-10)

  A crystallographic indexing algorithm, pinkIndexer, is presented for the analysis of snapshot diffraction patterns. It can be used in a variety of contexts including measurements made with a monochromatic radiation source, ...
