Application of μ-XAFS for the determination of the crystallization ratio in a series of vitro-ceramic materials containing industrial waste

Atomic spectrometry update. X-ray fluorescence spectrometry

“…The XRF data indicated the formation of a complete 2:1 monolayer whereas XAS suggested the presence of more than one structure of titanium oxide after use. Pinakidou et al 303 studied EXAFS spectra of Fe in a series of vitrified Fe and Pb rich industrial waste samples that contained toxic ash. XRF mapping in combination with m-XAS of samples containing 50% and 60% ash demonstrated that annealing at temperatures above 600 1C induced loss of homogeneity and the formation of Fe rich micro-crystalline ''islands''.…”

Two-step hard X-ray focusing combining Fresnel zone plate and single-bounce ellipsoidal capillary

“…However, single-bounce capillaries proposed by Balaic et al (1995) show a great potential in developing nanofocusing techniques. Parabolic and elliptical capillaries have a large focal distance and very high reflectivity (Balaic et al, 1995;Huang & Bilderback, 2003; Bartoll et al, 2004;Bjeoumikhov et al, 2005;Pinakidou et al, 2006). In a typical process the predetermined capillary profile is achieved by 'pulling' an originally straight uniform glass tube with accurate control of mechanical movements and heating parameters.…”
