The temperature dependence of the cation distribution in CuAl2O4 spinel has been determined from 600 to 1100°C on quenched specimens by powder X-ray diffraction, and from room temperature to 1000°C by in-situ high-temperature powder neutron diffrac

Generalized ellipsometry allows complete extraction of the dielectric function tensor, including orientation, from measurement of skew-cut single crystal orthorhombic absorbing materials. As an example, Stibnite (Sb2S3) is studied to determine fundam

The compounds tetrakis(trimethylsilyl)methane C[Si(CH3)3]4 (TC) and tetrakis(trimethylsilyl)silane Si[Si(CH3)3]4 (TSi) have crystal structures with the molecules in a cubic closed-packed (c.c.p.) stacking. At room temperature both structures have spa

Two-dimensional 31P spin diffusion MAS NMR experiments on polycrystalline Cd3(PO4)2, using a broad-banded dipolar recoupling scheme, are reported. Quantitative analysis of the 31P spin diffusion experiments as a function of mixing times yields unambi

It is demonstrated on a polycrystalline powder sample of Cd3(PO4)2, given a known single-crystal X-ray structure, that two-dimensional 31P double-quantum single-quantum MAS correlation experiments allow unique assignment of multiple 31P resonances to

Magnetic and mineralogical data were obtained on a sequence of titanomagnetite - titanomaghemite solid solutions from four basalt samples (0 to 70 Ma) dredged from four sites along a traverse normal to the mid-Atlantic Ridge. Data which characterized

CRYSTALLINE DIMETHYLAMINOMETHANE-DIPHOSPHONIC ACID: THE EXISTENCE OF ANHYDROUS AND MONOHYDRATE FORMS

There has been some discrepancy in the literature as to whether solid dimethylarninornethanediphosphonic acid existed as the anhydrous form or the monohydrate. We report the synthesis and characterization of both forms. 31P solid-state NMR data are g

A new global approach, called 'Generalized Ellipsometry', is now capable to characterize the optical and structural properties of general anisotropic layered systems, including absorption, and can be applied, in general, to determine the linear respo
