AI Article Synopsis

  • The study examines how various metals (Br, Ca, Cl, etc.) are distributed in the root system of the wetland plant Phragmites australis and the role of Fe nanoparticles in affecting metal mobility.
  • Researchers used advanced synchrotron techniques to analyze samples collected from the Yangtze River intertidal zone in July 2013.
  • Findings reveal that Fe nanoparticles are found in the root epidermis and their presence is linked to higher levels of other metals, indicating their significant role in metal scavenging within the plant's root system.

Article Abstract

This study investigates the distributions of Br, Ca, Cl, Cr, Cu, K, Fe, Mn, Pb, Ti, V and Zn in Phragmites australis root system and the function of Fe nanoparticles in scavenging metals in the root epidermis using synchrotron X-ray microfluorescence, synchrotron transmission X-ray microscope measurement and synchrotron X-ray absorption near-edge structure techniques. The purpose of this study is to understand the mobility of metals in wetland plant root systems after their uptake from rhizosphere soils. Phragmites australis samples were collected in the Yangtze River intertidal zone in July 2013. The results indicate that Fe nanoparticles are present in the root epidermis and that other metals correlate significantly with Fe, suggesting that Fe nanoparticles play an important role in metal scavenging in the epidermis.

Size-Effect Enriched Phase Diagram in -Type Skutterudite Superconductor IrSb.

Pressurized IrX (X = P and As) stands out as the sole -type superconductors among dozens of filled-skutterudites that are primarily characterized by -type charge carriers. The emergence of superconductivity is proposed to be intimately related to the inharmonic rattling phonons originating from the filled atoms. Here, we explore the impact of the size effect of the rattling atoms by substituting X with Sb, whose radius is 30 and 17% larger than those of P and As, respectively.

Unlabelled: During infection, bacterial pathogens rely on secreted virulence factors to manipulate the host cell. However, in gram-positive bacteria, the molecular mechanisms underlying the folding and activity of these virulence factors after membrane translocation are not clear. Here, we solved the protein structures of two secreted parvulin and two secreted cyclophilin-like peptidyl-prolyl isomerase (PPIase) ATP-independent chaperones found in gram-positive streptococcal species.

Synchrotron X-ray microtomography (S-µCT) is a highly valuable technique for investigating organ function and pathologies. However, its application is often limited by high radiation doses and the occurrence of ring artifacts. While S-µCT utilizing sparse-view projections can effectively decrease radiation doses, the reconstructed images frequently exhibit severe streaking artifacts, which are exacerbated by ring artifacts, ultimately compromising reconstruction accuracy, image quality, and resolution.

Fourth-generation synchrotron sources promise an enormous increase in the spatial coherence of X-ray radiation. In the EUV to soft X-ray range, the spatial coherence could reach almost 100% in both the horizontal and vertical directions. Identifying and understanding potential sources of degradation in the spatial coherence of X-rays transported along the beamline is critical to enable optimal performance for the experiments at the beamlines.

Background: K-edge subtraction (KES) imaging is a dual-energy imaging technique that enhances contrast by subtracting images taken with x-rays that are above and below the K-edge energy of a specified contrast agent. The resulting reconstruction spatially identifies where the contrast agent accumulates, even when obscured by complex and heterogeneous distributions of human tissue. This method is most successful when x-ray sources are quasimonoenergetic and tunable, conditions that have traditionally only been met at synchrotrons.
