Controlled Synthesis of Carbon-Encapsulated Copper Nanostructures by Using Smectite Clays as Nanotemplates [PDF]

open access: yes, 2012
Rhomboidal and spherical metallic-copper nanostructures were encapsulated within well-formed graphitic shells by using a simple chemical method that involved the catalytic decomposition of acetylene over a copper catalyst that was supported on different ...

ELECTRIC FIELD GRADIENT AT Fe2+SITES IN TRIOCTAHEDRAL LAYER SILICATES

open access: yesLe Journal de Physique Colloques, 1979
We have examined a series of sheet silicates, both in single crystal form in an applied magnetic field (biotite, chlorite, vermiculite) and as powders in the magnetically ordered state (greenalite, berthierine). It is found that VZZ is negative in the 1 : 1 minerals, that η ≤ 0,2 and that the Z-axis is close to the c-axis of the silicate. These results

Mineralogy and chemistry of altered Icelandic basalts: Application to clay mineral detection and understanding aqueous environments on Mars [PDF]

open access: yes, 2012
We used a suite of techniques, including those emulating compositional data sets obtained from Mars orbit and obtainable at the Mars surface, to examine aqueous alteration of basaltic rocks from Iceland as a mineralogic and geochemical analog for ...
