New article by Torres et al. in Nanomaterials

Synthetic amorphous silica is one of the most used nanomaterials, and numerous toxicological studies have studied its effects. Most of these studies have used an acute exposure mode to investigate the effects immediately after exposure. However, this exposure modality does not allow the investigation of the persistence of the effects, which is a crucial aspect of silica toxicology, as exemplified by crystalline silica. Read More

New article by Châtel et al. in NanoImpact

Production of Manufactured Nanomaterials (MNMs) has increased extensively due to economic interest in the current years. However, this widespread use raises concern about their impact on human and environment. Read More

New article by Slomberg et al. in Royal Society of Chemistry

Short-term, aqueous aging of a commercial nanocomposite TiO2 UV filter with a protective SiO2 shell was examined in abiotic simulated fresh- and seawater. Read More

New article by Marchioni et al. in The Journal of Physical Chemistry

Article on "Thiolate-Capped Silver Nanoparticles: Discerning Direct Grafting from Sulfidation at the Metal-Ligand Interface by Interrogating the Sulfur Atom" by Marchioni, M., Battocchio, C., Joly, Y., Gateau, C., Nappini, S., Pis Read More

PhD position on invertebrate nanotoxicology at Université de Genève

Candidates should hold a Master degree comparable to a Swiss University M.Sc in biology, biochemistry, environmental science or equivalent. The candidate should have a strong interest in scientific research and the aquatic environment. Read More

New article by Auffan et al. in Environmental Science: Nano

Silver nanomaterials with different shapes (spheres, plates, wires, rods, cubes) are valued by industries and scientists for their shape-dependent properties which make them useful for diverse applications. In a safer-by-design perspective, controlling the shape of silver nanomaterials could be an option to increase their properties while lowering either their hazard or their exposure potentials.

New article by Fiorentino et al. in Geoscientific Model Development Discussions

Homogeneous reactivity has been extensively studied over the past years through outdoor air-quality simulations. However, indoor atmospheres are known to be largely influenced by another type of chemistry, that is reactivity with surfaces. Read More

New article by Dussert et al. in Nanomaterials

Synthetic amorphous silica (SAS) is used in numerous applications and included in many daily products to which humans are exposed via inhalation, ingestion, or skin contact. Read More

New article by Stimpson et al. in Biomacromolecules

Interactions between polysaccharides, specifically between cellulose and hemicelluloses like xyloglucan (XG), govern the mechanical properties of the plant cell wall. This work aims to understand how XG molecular weight (MW) and the removal of saccharide residues impact the elastic modulus of XG–cellulose materials. Read More

New article by Nasiri et al. in Applied Clay Science

The flourishing market of nanocomposite food packaging has raised concerns about the safety of these materials. While several works on this issue have been published in recent years, they main focus in these studies was found to be on the possible migration of the nanoparticle its constituents. Read More
