Dioxygen reacts with the gold(I) hydride (IPr)AuH under insertion to give the hydroperoxide (IPr)AuOOH, a long-postulated reaction in gold catalysis and the first demonstration of O2 activation by Au-H in a well-defined system. Subsequent condensation gave the peroxide (IPr)Au-OO-Au(IPr) (IPr = 1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene). The reaction kinetics are reported, as well as the...


 Osteoma osteóide (OO) é definido como um tumor ósseo osteoblástico, benigno, acometendo com maior frequência pacientes jovens do sexo masculino. Devido à sua raridade e sintomatologia inespecífica, o diagnóstico OO no pé pode ser postergado confundido doenças levando ausência correto por anos.
 Neste relato, apresentamos caso de paciente masculino 22 anos osteoma tálus que teve seu ...

Fast and effective analytical screening tools providing new suitable authenticity markers applicable to a large number of samples are required efficiently control the global olive oil (OO) production, allow rapid detection low levels adulterants even with fatty acid composition similar OO. The present study aims develop authentication models for comprehensive illegal blends OO including differe...

We demonstrate that oxygen-oxygen (OO) collisions at the LHC provide unprecedented sensitivity to parton energy loss in a system whose size is comparable those created very peripheral heavy-ion collisions. With leading and next-to-leading order calculations of nuclear modification factors, we show baseline absence partonic rescattering known with up 2% theoretical accuracy inclusive OO Surprisi...
