We are carrying out detailed study of the X-ray and infrared (IR) properties of a sample of local (d < 70Mpc) luminous infrared galaxies (LIRGs) using XMM-Newton and Spitzer (imaging and spectroscopy)...
Single crystals (0.1(R)C0.5 mm) of natural heulandite from Nasik (India) were treated in M NaCl solution at 423 K for 12 weeks, yielding almost fully Na-exchanged heulandite (composition: Ca K [Al ...
Twenty-nine chlorites, seventeen lithium-free micas, and twenty-two lithium-bearing micas from diverse localities have been studied by X-ray diffraction, microprobe, and optical second harmonic genera...
To explain the large values of the quadrupole splittings and line widths in the M鰏sbauer spectrum of oxybiotite, a formalized analysis of the distribution of effective charges in the anion network was...
An X-ray diffraction analysis of a barium-vermiculite shows it to have a triclinic unit cell with the following dimensions a = 5.33, b = 9.26, c = 12.47 侌, 兛 = 100.75亱 兝 = 93.5亱 and 兞 = 90亱. The propo...
Lysine and vermiculite form a stable, ordered, interlamellar complex which has a well defined superlattice structure with respect to the ab-plane of vermiculite. The lysine molecules lie at a low angl...
Small angle X-ray scattering curves have been obtained for a series of Na Wyoming Bentonite clay samples containing 10% clay by weight and NaPO3 in concentrations ranging from 0 to 100 meq/l. From the...
