متن کاملThe Trapped Heavy Noble Gases in Recently Found Martian Meteorites
Introduction: Noble gases in Martian meteorites are an important source of our knowledge of composition and evolution of the volatile inventory of Mars [1]. Ancient (ALH 84001), fractionated (nakhlites), and recent atmosphere (shock-produced glass in shergottite EETA 79001) as well as at least one component originating from the interior (Chassigny) have been identified based on analyses of the ...
متن کاملMicrowave observation of the "recently found" polar OCS dimer.
Recently Afshari et al. reported on the detection of a new infrared band which was assigned to the "long-anticipated polar isomer of the OCS dimer" [J. Chem. Phys. 126, 071102 (2007)]. The authors report here the microwave confirmation of their results. The lowest energy, nonpolar isomer of (OCS)2 has long been known from IR spectroscopy, while the polar form has only been deduced from qualitat...
متن کامل2C-B: a new psychoactive phenylethylamine recently discovered in Ecstasy tablets sold on the Swiss black market.
This study sought to identify, by means of several analytical methods (GC-MS, HPLC-DAD, CE-DAD, FTIR, and NMR), 4-bromo-2,5-dimethoxyphenethylamine (2C-B), which was found in two sets of tablets obtained from the Swiss black market. Unequivocal identification of 2C-B was only achieved by a combination of mass spectrometric and NMR analysis. Quantitation of 2C-B was performed by HPLC-DAD and CE-...
متن کاملNew horizon in platelet function: with special reference to a recently-found molecule, CLEC-2
Platelets play a key role in the pathophysiological processes of hemostasis and thrombus formation. However, platelet functions beyond thrombosis and hemostasis have been increasingly identified in recent years. A large body of evidence now exists which suggests that platelets also play a key role in inflammation, immunity, malignancy, and furthermore in organ development and regeneration, such...
