HETEROGENEOUS CONDENSATION OF PRESOLAR TITANIUM CARBIDE CORE-GRAPHITE MANTLE SPHERULES

Chigai T.; Yamamoto T.; Kozasa T. (2002)

Abstract— We investigate heterogeneous nucleation and growth of graphite on precondensed TiC grains in the gas outflows from carbon-rich asymptotic giant branch (AGB) stars employing a newly-derived heterogeneous nucleation ...
LATE CRETACEOUS TO EARLY PALEOGENE PALEOMAGNETIC RESULTS FROM SIKHOTE ALIN, FAR EASTERN RUSSIA: IMPLICATIONS FOR DEFORMATION OF EAST ASIA

Otofuji Y.i.; Shibata T.; Matsumoto M.; Yamamoto T.; Morimoto C.; Kulinich R.G.; Matsuda T.; Itaya T.; Zimin P.S.; Matunin A.P.; Sakhno V.G.; Kimura K. (1995)

Welded tuffs in the Bogopol and Sijanov groups were sampled at 27 sites from 12 caldera formations in the Sikhote Alin mountain range around Kavalerovo (44.3°N, 135.0°E) for chronological and paleomagnetic studies. KAr age ...
SUBSTITUTION MECHANISM OF AL IONS IN MGSIO3 PEROVSKITE UNDER HIGH PRESSURE CONDITIONS FROM FIRST-PRINCIPLES CALCULATIONS

Yamamoto T.; Yuen D.A.; Ebisuzaki T. (2003)

Large-scale first-principles density functional theory (DFT) calculations have been carried out to investigate how Al3+ can be incorporated into MgSiO3 perovskite under high pressure and to study the resultant change in ...
