Phase compositions and equilibria in the CaO-Al2O3-Fe2O3-SO3 system, for assemblages containing ye'elimite and ferrite Ca-2(Al,Fe)O-5

Phase equilibria in the CaO-Al2O3-Fe2O3-SO3 system have been studied, mainly at 1325 degrees C. In particular the solid solution compositions of ye'elimite Ca-4(Al6O12)SO4 and brownmillerite (C-2(A,F)) phases have been analysed and used to estimate the com ...

Synthesis and equation of state of perovskites in the (Mg, Fe)(3)Al2Si3O12 system to 177 GPa

Susannah McGregor Dorfman

Natural and synthetic pyrope-almandine compositions from 38 to 100 mol% almandine (Alm38-Alm100) were studied by synchrotron X-ray diffraction in the laser-heated diamond anvil cell to 177 GPa. Single-phase orthorhombic GdFeO3-type perovskites were synthes ...

Evaluation of silicate minerals for pH control during bioremediation: Application to chlorinated solvents

David Andrew Barry, Christof Holliger, Alessandro Brovelli, Elsa Marina Lacroix

Accurate control of groundwater pH is of critical importance for in situ biological treatment of chlorinated solvents. This study evaluated a novel approach for buffering subsurface pH that relies on the use of silicate minerals as a long-term source of al ...

In-situ grown horizontal carbon nanotube membrane

Mihai Adrian Ionescu, Dimitrios Tsamados, Hoël Maxime Guérin

We present the successful fabrication of horizontally grown and dense carbon nanotube (CNT) membranes in situ. A TiN/Al2O3/TiN stack is first patterned to be employed as a support for the CNT growth. Iron is then evaporated with a 45 degrees tilt angle on ...

Window layer with p doped silicon oxide for high V-oc thin-film silicon n-i-p solar cells

Christophe Ballif, Franz-Josef Haug, Jordi Escarre Palou, Céline Pahud, Rémi Biron

We investigate the influence of the oxygen content in boron-doped nanocrystalline silicon oxide films (p-nc-SiOx) and introduce this material as window layer in n-i-p solar cells. The dependence of both, optical and electrical properties on the oxygen cont ...

Ruthenium-Catalyzed Synthesis of 1,5-Dichlorides by Sequential Intermolecular Kharasch Reactions

Rosario Scopelliti, Kay Severin, Aurélien Godinat, Katrin Anne Thommes, Charlotte Buron

Sequential intermolecular atom transfer radical addition reactions of activated dichlorides Cl2CRR′ (R = CN, CO2Et, R′ = H, CN, CO2Et) with two olefins catalyzed by [Cp*RuCl2(PPh3)] in the presence Mg allow the synthesis of linear 1,5-dichlorides. Differen ...

Microstructural development of early age hydration shells around cement grains

Karen Scrivener, Emmanuel Gallucci, Prakash Chandra Mathur

An important microstructural aspect of the early hydration of Portland cement (K) is the formation of a shell of hydration products around cement grains. There is, at present, limited information on the mechanism of formation of the shell and of the chemis ...

Molecular wiring of LiMnPO4 (olivine) by ruthenium(II)-bipyridine complexes

Michael Graetzel, Shaik Mohammed Zakeeruddin, Ladislav Kavan

LiMnPO4 (olivine) was surface-modified by two different complexes: Ru-bis(4,4'-diethoxycarbonyl-2,2'-bipyridine)(4,4'-dicarboxylate-2,2'-bipyridine) and Ru-bis(4-carboxylic acid-4'-carboxylate-2,2'-bipyridine)(4,4'-dinonyl-2,2'bipyridine). These complexes ...

A multiscale approach to model the anisotropic deformation of lithospheric plates

Roland Logé

The association of experimental data showing that the plastic deformation of olivine, the main constituent of the upper mantle, is highly anisotropic and the ubiquitous seismic anisotropy in the upper mantle, which indicates that olivine crystals show cohe ...

Structural reactivation in plate tectonics controlled by olivine crystal anisotropy

Roland Logé

Reactivation of structures inherited from previous collisional or rifting events, especially lithospheric-scale faults, is a major feature of plate tectonics. Its expression ranges from continental break-up along ancient collisional belts to linear arrays ...
