a r t i c l e i n f o Keywords: pressure-induced phase transition postperovskite super-Earth 10 solar giants first principles The fate of MgSiO 3 post-perovskite under TPa pressures is key information for understanding and modeling interiors of super-Earths-type exoplanets and solar giants' cores. Here, we report a dissociation of MgSiO 3 post-perovskite into CsCl-type MgO and P2 1 /c-type MgSi...

Exoplanet research focusing on the characterization of super-Earths is currently limited to the handful of targets orbiting bright stars that are amenable to detailed study. This Letter proposes to look at alternative avenues to probe the surface and atmospheric properties of this category of planets, known to be ubiquitous in our galaxy. I conduct Markov Chain Monte Carlo light-curves analyses...

A procedure for the efficient extraction and separation of rare earths and other valuable elements from used NdFeB permanent magnets is presented. In a first step, an iron free leachate is prepared from an used magnet using nitric acid. Cobalt is separated through a liquid–liquid extraction in aqueous nitrate media using as organic phase the ionic liquid trihexyl(tetradecyl)phosphonium nitrate ...

purpose : granular cell tumors (gct) are benign unusual neoplasms which have been proven to have a schwann cell phenotype. they rarely occur in the eye region. case reports : we report three cases of gct in the ocular adnexa including palpebra, subconjuctiva and orbit which rarely occur. patients are, a young girl with the lesion in orbit and presentation of proptosis, a middle aged man with th...

introduction penetration of a bicycle brake handle into the orbit is a rare and serious type of trauma. globe subluxation due to such trauma has not been previously reported. case presentation a 10-year-old girl presented after falling from a bicycle, which resulted in the handbrake penetrating her right upper eyelid. on examination, the globe was subluxated anteriorly, there was no light perce...

With Google Earth being widely used by the general public and professionals, Virtual Globes are revolutionizing the way in which scientists conduct their research and the general public uses geospatial-related data and information. NASA Goddard Earth Science Data and Information Service Center (GES DISC) developed a service-oriented online scientific data analysis system to provide customable o...

Although most of the rare earth metals were discovered in Sweden, the industrialisation started in the Austrian Empire. This was due to the fact that the Swedish chemist Jons Fridrik Bahr (1815–1875) from Uppsala went to Heidelberg in Germany in 1855 to analyse some rare earth minerals by the spectroscope discovered recently by chemistry professor Robert Bunsen (1811– 1899) and his colleague ph...
