It is now widely accepted that describing and labeling of chemicals as developmental toxicants on a purely qualitative basis does not make sense. Agents possessing the potential to induce reproductive or developmental toxicity present a risk of human harm only under certain conditions. This critical fact cannot be properly communicated with a simple designation as "positive" or "negative". Rath...

A concise synthesis of Pd nanoparticles encapsulated in a sponge-like carbonaceous support (Pd/C) was achieved by mixing a solution containing water, ethylene glycol and Pd(II) with diphosphorus pentoxide, leading to excellent catalytic performance of Pd/C towards the reduction of the model aromatic nitro compound.

new forms of vanadium oxide nanoporous were fabricated using a simple chemical synthesis method. vanadium pentoxide (v2o5) nanoporous were synthesized by sodium metavanadate as precursor and ethylene glycol as surfactant. the samples were characterized by high resolution transmission electron microscopy (hrtem), field effect scanning electron microscopy (fesem) and x-ray diffraction (xrd), four...

In a previous paper we (Diggle and Gage, 1954) have referred to published statements that the toxicity of ozone is increased if oxides of nitrogen are present and we have suggested the hypothesis that if, in fact, this is so, then the increased toxicity is likely to be due to the presence of nitrogen pentoxide, to which the lower oxides of nitrogen are converted by ozone. As a first step to est...

The title compound, C(10)H(12)N(2)O(2), was synthesized by cyclization of 3-(1-ethyl-pyrrole-2-carboxamido)propanoic acid in the presence of polyphospho-ric acid and diphospho-rus pentoxide. In the crystal structure, adjacent mol-ecules are linked by N-H⋯O hydrogen bonds, forming chains extending along the b axis.
