Journal ArticleDOI
Solution Synthesis of Germanium Nanocrystals: Success and Open Challenges
Daniele Gerion,Natalia Zaitseva,Cheng Saw,Maria Francesca Casula,Sirine Fakra,Tony van Buuren,Giulia Galli +6 more
TL;DR: In this paper, a two-step synthesis route that yields nanometer-size crystalline germanium in the form of a black powder is presented, which relies on high temperature decomposition of tetraethylgermane (TEG) in organic solvents.
Journal ArticleDOI
Iron-reducing bacteria accumulate ferric oxyhydroxide nanoparticle aggregates that may support planktonic growth.
Birgit Luef,Sirine Fakra,Sirine Fakra,Roseann Csencsits,Kelly C. Wrighton,Kenneth H. Williams,Michael J. Wilkins,Kenneth H. Downing,Philip E. Long,Luis R. Comolli,Jillian F. Banfield +10 more
TL;DR: Planktonic microbial communities sampled from an aquifer in Rifle, Colorado, USA, close to the peak of iron reduction following in situ acetate amendment are characterized and cell surface Fe(III) accumulation may be a general mechanism by which FeRB can grow while in planktonic suspension.
Journal ArticleDOI
Correlative Cryogenic Spectromicroscopy to Investigate Selenium Bioreduction Products
Sirine Fakra,Sirine Fakra,Birgit Luef,Birgit Luef,Cindy J. Castelle,Cindy J. Castelle,Sean W. Mullin,Sean W. Mullin,Kenneth H. Williams,Kenneth H. Williams,Matthew A. Marcus,Matthew A. Marcus,Denise Schichnes,Denise Schichnes,Jillian F. Banfield,Jillian F. Banfield +15 more
TL;DR: An apparatus that allows the correlation of cryogenic transmission electron microscopy (cryo-TEM) and synchrotron hard X-ray microprobe (SHXM) data sets to precisely determine the distribution, valence state, and structure of selenium in biofilms sampled from a contaminated aquifer near Rifle, CO is developed.
Journal ArticleDOI
Surface Structure of CdSe Nanorods Revealed by Combined X-ray Absorption Fine Structure Measurements and ab Initio Calculations
Deborah M. Aruguete,Matthew A. Marcus,Liang-shi Li,Andrew Williamson,Sirine Fakra,Franciois Gygi,Giulia Galli,A. Paul Alivisatos +7 more
TL;DR: In this paper, orientation-specific surface-sensitive structural characterization of colloidal CdSe nanorods with extended X-ray absorption fine structure spectroscopy and ab initio density functional theory calculations is presented.
Selenium accumulation in flowers and its effects on pollination. New Phytol
Colin F. Quinn,Christine N. Prins,John L. Freeman,Amanda M. Gross,Laura J. Hantzis,Ray J. B. Reynolds,Soo In Yang,Paul A. Covey,Gary Banuelos,Ingrid J. Pickering,Sirine Fakra,Matthew A. Marcus,H. S. Arathi,Elizabeth A. H. Pilon Smits +13 more
TL;DR: In this paper, the authors investigated floral Se distribution and speciation in flowers, and the effects of floral Se on pollen quality and plant-pollinator interactions in Stanleya pinnata and Brassica juncea.
