TL;DR: In this paper, the impact of commercial metal oxide nanoparticles (NPs) on wheat grown in a solid matrix, sand, was investigated using dynamic light scattering and atomic force microscopy (AFM).

TL;DR: It is shown that c-type cytochromes of a dissimilatory metal-reducing bacterium, Shewanella oneidensis MR-1, are essential for the reduction of U(VI) and formation of extracelluar UO 2 nanoparticles and this is the first study to the authors' knowledge to directly localize the OM-associated cyto Chromes with EPS, which contains biogenic UO2 nanoparticles.

TL;DR: In this article, X-ray absorption fine structure (XAFS) measurements were used at the U L3-edge to directly determine the pH dependence of the cell wall functional groups responsible for the absorption of aqueous UO22+ to Bacillus subtilis from pH 1.67 to 4.80.

TL;DR: Findings demonstrate the similarities between commercial NPs and MPs of CuO or ZnO in wheat plants, with greater root toxicity correlating with smaller particle size, as well as the influence of factors from the sand and the plant on the aggregation or dissolution of both types of particles.

TL;DR: In this paper, the local atomic environment of Cd bound to the cell wall of the gram-positive bacterium Bacillus subtilis was determined by X-ray absorption fine structure (XAFS) spectroscopy.
