Analysis of Dawn spacecraft Framing Camera image data allows evaluation of the topography and geomorphology of features on the surface of Ceres. The dwarf planet is dominated by numerous craters, but other features are also common. Linear structures include...

Isolation of a neutral boron-containing radical stabilized by a cyclic (alkyl)(amino)carbene.

Angewandte Chemie (International ed. in English)

Bissinger P, Braunschweig H, Damme A, Krummenacher I, Phukan AK, Radacki K, Sugawara S.
PMID: 24917474

Utilizing a cyclic (alkyl)(amino)carbene (CAAC) as a ligand, neutral CAAC-stabilized radicals containing a boryl functionality could be prepared by reduction of the corresponding haloborane adducts. The radical species with a duryl substituent was fully characterized by single-crystal X-ray structural...

The YPrO3+δ system is a nearly ideal model system for the investigation of oxide defect creation and annihilation in oxide ion conductor related phases with potential applications as solid state electrolytes in solid oxide fuel cells. The formation, structure,...

Olivine in an unexpected location on Vesta's surface.

Nature

Ammannito E, De Sanctis MC, Palomba E, Longobardo A, Mittlefehldt DW, McSween HY, Marchi S, Capria MT, Capaccioni F, Frigeri A, Pieters CM, Ruesch O, Tosi F, Zambon F, Carraro F, Fonte S, Hiesinger H, Magni G, McFadden LA, Raymond CA, Russell CT, Sunshine JM.

Olivine is a major component of the mantle of differentiated bodies, including Earth. Howardite, eucrite and diogenite (HED) meteorites represent regolith, basaltic-crust, lower-crust and possibly ultramafic-mantle samples of asteroid Vesta, which is the lone surviving, large, differentiated, basaltic rocky...

Plant functional types do not predict biomass responses to removal and fertilization in Alaskan tussock tundra.
