The risk of chemical mixtures to ecosystems is often assessed by applying the model of concentration addition or response addition combined with species sensitivity distribution (SSD) curves. Mixture effect predictions have been shown to be consistent only ...

The synthesis and full characterization of a well-defined silica-supported :Si-O-W(Me)(5) species is reported. Under an inert atmosphere, it is a stable material at moderate temperature, whereas the homoleptic parent complex decomposes above -20 degrees C, ...
Enzymic haem and non-haem high-valent iron-oxo species are known to activate strong C-H bonds, yet duplicating this reactivity in a synthetic system remains a formidable challenge. Although instability of the terminal iron-oxo moiety is perhaps the foremos ...
The paper provides the first estimate of the role of abiotic and anthropogenic variables driving both alien plant species richness and composition covering the whole region of the European Alps. To establish and spread in a new area, alien plants must be a ...
Interspecies variation in sensitivity to synthetic chemicals can be orders of magnitude large. Species traits causing the variation can be related to toxicokinetics (uptake, distribution, biotransformation, elimination) or toxicodynamics (interaction with ...
Dodecaborates, i.e. the [B12H12]2- containing species, are often observed as main intermediates in the hydrogen sorption cycle of metal borohydrides, hindering rehydrogenation. In the decomposition process of Y(BH4)3, yttrium octahydrotriborate, i.e. Y(B3H ...
Cerium(III) and cerium(IV) both form formate complexes. However, the species in aqueous solution and the solid-state structures are surprisingly different. Ce(III) shows only mononuclear complexes in aqueous solution, whereas Ce(IV) forms a stable hexanucl ...
In grassland communities, plants can be classified as dominants or subordinates according to their relative abundances, but the factors controlling such distributions remain unclear. Here, we test whether the presence of the arbuscular mycorrhizal (AM) fun ...
The present invention generally relates to microfluidics, and to spray drying and other drying techniques. Various embodiments of the invention are generally directed to systems and methods for drying fluids contained within a channel such as a microfluidi ...
A very high percentage (around 70%) of the agronomic area in Switzerland is covered by grasslands at various altitudes where environmental conditions, management, community structure and productivity vary widely. As heat waves and drought are predicted to ...
