TL;DR: The solubility-driven toxicity and antibacterial activities of Ag NWs suspension and its ultracentrifuged particle-free supernatant were equal, and the latter indicated that the toxic effects of ~80–100 nm Ag nanostructures to Escherichia coli were solely dependent on their dissolution and no shape-induced/related effects were observed.
Abstract: Silver nanoparticles are extensively used in antibacterial applications. However, the mechanisms of their antibacterial action are not yet fully explored. We studied the solubility-driven toxicity of nm (mean primary diameter × length) silver nanowires (NWs) to recombinant bioluminescent Escherichia coli as a target representative of enteric pathogens. The bacteria were exposed to silver nanostructures in water to exclude the speciation-driven alterations. Spherical silver nanoparticles (83 nm mean primary size) were used as a control for the effect of NPs shape. Toxicity of both Ag NWs and spheres to E. coli was observed at similar nominal concentrations: the 4h EC50 values, calculated on the basis of inhibition of bacterial bioluminescence, were 0.42 ± 0.06 and 0.68 ± 0.01 mg Ag/L, respectively. Dissolution and bioavailability of Ag from NWs and nanospheres, analyzed with AAS or Ag-sensor bacteria, respectively, suggested that the toxic effects were caused by solubilized Ag

TL;DR: The first significant P-rich deposits appear in the global rock record during the Paleoproterozoic around 2 Ga, however the specific triggers that led to apatite precipitation are still under debate as mentioned in this paper.

TL;DR: The mechanism of the Horner−Wadsworth−Emmons (HWE) reaction has been investigated using high level quantum mechanical calculations on a realistic model system as mentioned in this paper.
Abstract: The mechanism of the Horner−Wadsworth−Emmons (HWE) reaction has been investigated using high level quantum mechanical calculations on a realistic model system. The solvation contribution has been evaluated using the PCM/DIR method. In the free, anionic system, the rate-determining step was found to be the ring closure of an oxyanion to an oxaphosphetane. Solvation was found to have a drastic influence on the reaction path. In most solvated systems, the bimolecular formation of the oxyanion intermediate may be rate limiting. Previously postulated isomerization side paths were investigated. Several effects that could rationalize experimentally observed trends for (E)/(Z)-selectivities have been identified.
