Sea urchin immune cells and associated microbiota co-exposed to iron oxide nanoparticles activate cellular and molecular reprogramming that promotes physiological adaptation.

The innate immune system is the first player involved in the recognition/interaction with nanomaterials. Still, it is not the only system involved. The co-evolution of the microbiota with the innate immune system built an interdependence regulating immune homeostasis that is poorly studied.

Sulfonated Pentablock Copolymer (Nexar) for Water Remediation and Other Applications.

This review focuses on the use of a sulfonated pentablock copolymer commercialized as Nexar in water purification applications. The properties and the use of sulfonated copolymers, in general, and of Nexar, in particular, are described within a brief reference focusing on the problem of different water contaminants, purification technologies, and the use of nanomaterials and nanocomposites for water treatment. In addition to desalination and pervaporation processes, adsorption and photocatalytic processes are also considered here.

Impact of Doping on Cross-Sectional Stress Assessment of 3C-SiC/Si Heteroepitaxy.

In this paper, we used micro-Raman spectroscopy in cross-section to investigate the effect of different doping on the distribution of stress in the silicon substrate and the grown 3C-SiC film. The 3C-SiC films with a thickness up to 10 μm were grown on Si (100) substrates in a horizontal hot-wall chemical vapor deposition (CVD) reactor. To quantify the influence of doping on the stress distribution, samples were non-intentionally doped (NID, dopant incorporation below 10 cm), strongly n-type doped ([N] > 10 cm), or strongly p-type doped ([Al] > 10 cm).
