Journal ArticleDOI
Microplankton trace element contents: implications for mineral limitation of mesozooplankton in an HNLC area
Stephen B. Baines,Xi Chen,Stefan Vogt,Nicholas S. Fisher,Benjamin S. Twining,Michael R. Landry +5 more
TL;DR: In this paper, elemental microanalysis (SXRF) of single-celled plankton was used to determine their trace metal contents during a series of semi-Lagrangian drift studies in an HNLC upwelling region, the Costa Rica Dome (CRD).
Journal ArticleDOI
Unsupervised cell identification on multidimensional X-ray fluorescence datasets.
TL;DR: A novel approach to locate, identify and refine positions and whole areas of cell structures based on elemental contents measured by X-ray fluorescence microscopy that can obtain consistent identification of whole cells, even when cells are overlapping, without training by explicit annotation.
Journal ArticleDOI
Elemental profiling of single bacterial cells as a function of copper exposure and growth phase
TL;DR: The elemental composition of single cells of Nitrosomonas europaea was studied via synchrotron X-ray fluorescence microscopy (XFM) as a function of inhibition by divalent copper (Cu(II)) and batch growth phase to find out the impact of Cu inferred from specific oxygen uptake rate (sOUR) measurements at the two physiological states.
Journal ArticleDOI
Broadband X-ray ptychography using multi-wavelength algorithm
Yudong Yao,Yi Jiang,Jeffrey A. Klug,Youssef S. G. Nashed,Christian Roehrig,Curt Preissner,Fabricio Marin,Michael Wojcik,Oliver Cossairt,Zhonghou Cai,Stefan Vogt,Barry Lai,Junjing Deng +12 more
TL;DR: In this article, a multi-wavelength reconstruction algorithm has been developed to deal with the broad bandwidth in ptychography, which is more accurate in the physical model, and also considers the spot size variation as a function of energy due to the chromatic focusing optics.
Journal ArticleDOI
MicroXRF tomographic visualization of zinc and iron in the zebrafish embryo at the onset of the hatching period
TL;DR: The reconstructed volumetric data revealed distinct differences in the elemental distributions, with zinc predominantly localized to the yolk and yolk extension, and iron to various regions of the brain as well as the myotome extending along the dorsal side of the embryo.
