Silicon Isotope Fractionation between Silicate and Metal from an Enstatite Meteorite: Implications for Earth’s Core Formation
Introduction: The presence and amount of Si in Earth's core has important implications for models of the processes and chemistry of core segregation. A metal core containing 5 to 7 wt. % Si can be produced when assuming continuous accretion and equili-bration along the silicate liquidus terminating at ~35 GPa and ~3,000 K, and with a concomitant increase in fO 2 from 4 to 2 log units below IW [...
متن کاملItqiy: II. a short story about its noble gases and oxygen isotopes
Introduction: Itqiy is a unique coarse-grained, metal-rich enstatite meteorite that was recovered from Western Sahara in July 2000 [1,2]. The dominating mineral phase is a low Ca pyroxene that partly resembles EL chondritic enstatite. The other main constituent (about 25 vol%) is kamacite, which shows EH chondritic compositional characteristics. Additionally, a few tiny intergrowths of differen...
متن کاملKhatyrka, a new CV3 find from the Koryak Mountains, Eastern Russia
A new meteorite find, named Khatyrka, was recovered from eastern Siberia as a result of a search for naturally occurring quasicrystals. The meteorite occurs as clastic grains within postglacial clay-rich layers along the banks of a small stream in the Koryak Mountains, Chukotka Autonomous Okrug of far eastern Russia. Some of the grains are clearly chondritic and contain Type IA porphyritic oliv...
متن کاملSulfur-rich Carbonaceous Nanoglobules in the Tagish Lake Meteorite
Introduction: Understanding the distribution, chemistry, and structure of C in carbonaceous chondrites (CC) is fundamental to revealing information on early solar chemical evolution. The Tagish Lake CC has generated much interest partly because of its pristine nature and high C content [1,2,3]. Unique to the Tagish Lake CC are hollow carbonaceous nanoglobules [4]. These particles are morphologi...
متن کاملSolar cell efficiency enhancement using a hemisphere texture containing metal nanostructures
One major problem of the conventional solar cells is low conversion efficiency. In this work, we have proposed a new design including hemisphere texturing on top and metallic plasmonic nanostructure under the silicon layer to enhance the optical absorption inside the photosensitive layer. The finite-difference time-domain (FDTD) method has been used to investigate the interaction of light wi...
