Thermische Autoxydation und thermische Polymerisation des Styrols. Der Mechanismus der Startreaktion
1964
Die thermische Autoxydation des Styrols wurde bei verschiedenen Sauerstoffpartial drucken und in verschieden konzentrierten Losungen in Chlorbenzol mit Hilfe einer WARBURG-Apparatur gemessen. Aus den kinetischen Beziehungen folgt, das sich zuerst aus swei Styrolmolekulen ein Zwischenprodukt bildet, das von molekularem Sauerstoff unter Radikalbildung dehydriert wird. The thermal autoxidation of styrene was carried out in a WARBURG apparatus in different concentrations in chlorobenzene and under different partial pressures of oxygen. In consequence of the kinetic relations an intermediate is formed by two styrene molecules and this intermediate is dehydrated by molecular oxygen under the form…
A synergic nanoantioxidant based on covalently modified halloysite–trolox nanotubes with intra-lumen loaded quercetin
2016
We describe the preparation and properties of the first example of a synergic nanoantioxidant, obtained by different functionalizations of the external surface and the inner lumen of halloysite nanotubes (HNTs). Trolox, a mimic of natural α-tocopherol, was selectively grafted on the HNT external surface; while quercetin, a natural polyphenolic antioxidant, was loaded into the inner lumen to afford a bi-functional nanoantioxidant, HNT–Trolox/Que, which was investigated for its reactivity with transient peroxyl radicals and a persistent 1,1-diphenyl-2-picrylhydrazyl (DPPH˙) radical in comparison with the corresponding mono-functional analogues HNT–Trolox and HNT/Que. Both HNT–Trolox and HNT/Q…
Evaluating the neurotoxic effects of lactational exposure to persistent organic pollutants (POPs) in Spanish children.
2012
Although the brain continues developing in the postnatal period, epidemiological studies on the effects of postnatal exposure to neurotoxic POPs through breast-feeding remain mostly inconclusive. Failure to detect associations between postnatal exposure and health outcomes may stem from the limitations of commonly employed approaches to assess lactational exposure. The aim of the present study was to assess whether lactational exposure to polychlorinated biphenyl-153 (PCB-153), dichlorodiphenyldichloroethylene (DDE), or hexachlorobenzene (HCB) as estimated with a physiologically based pharmacokinetic (PBPK) model, is associated with decrements in mental and psychomotor development scores of…
