INTERIOR WOR(L)DS (vol. 2)
No full textThe traditional idea of Interior Architecture as design of home spaces has now become old-fashioned. Interior Architecture is increasingly adapting to the needs of contemporary society where spatial typologies are getting more and more hybrid.
The book contains a series of reflections of new approaches to interior architecture and the key words that govern it
The quantitative analysis of OH in vesuvianite: a polarized FTIR and SIMS study
No full textA well-characterized suite of vesuvianite samples from the volcanic ejecta (skarn or syenites) from Latium (Italy) was studied by single-crystal, polarized radiation, Fourier-transform infrared (FTIR) spectroscopy and secondary-ion mass-spectrometry (SIMS). OH-stretching FTIR spectra consist of a rather well-defined triplet of broad bands at higher-frequency (3,700-3,300 cm(-1)) and a very broad composite absorption below 3,300 cm(-1). Measurements with E//c or E perpendicular to c show that all bands are strongly polarized with maximum absorption for E//c. They are in agreement with previous band assignments (Groat et al. Can Mineral 33:609, 1995) to the two O(11)-H(1) and O(10)H(2) groups in the structure. Pleochroic measurements with changing direction of the E vector of the incident radiation show that the orientation of the 0(11)-H(l) dipole is OH(boolean AND)c similar to 35 degrees, in excellent agreement with the neutron data of Lager et al. (Can Mineral 37:763, 1999). A SIMS-based calibration curve at similar to 10% rel. accuracy has been worked out and used as reference for the quantitative analysis of H(2)O in vesuvianite by FTIR. Based on previous SIMS results for silicate minerals (Ottolini and Hawthorne in J Anal At Spectrom 16:1266, 2001; Ottolim et al. in Am Mineral 87:1477, 2002) the SiO(2) and FeO content of the matrix were assumed as the major factors to be considered at a first approximation in the selection of the standards for H. The lack of vesuvianite standards for quantitative SIMS analysis of H(2)O has been here overcome by selecting low-silica elbaite crystals (Ottolini et al. in Am Mineral 87:1477, 2002). The resulting integrated molar absorption FTIR coefficient for vesuvianite is epsilon(i) = 100.000 +/- 2.000 l mol(-1) cm(-2). SIMS data for Li, B, F, Sr, Y, Be, Ba REE, U and Th are also provided in the paper
