“…Therefore, it is probable that the large amount of Na + mass transport during annealing occurred by grain boundary diffusion. Hence, the reason for the significant decrease in the Na + levels after MB degradation was leaching of the watersoluble sodium species 73 from the surface-exposed grain boundaries. This leaching would alter both the composition and pH of the MB solution and thus affect MB degradation.…”

The present work reports data for the mineralogical and chemical properties of anatase thin films individually doped or codoped with chromium and vanadium, fabricated by sol-gel spin coating on glass substrates and annealing at 450 °C for 2 h. X-ray photoelectron spectroscopy data indicated the presence of Ti(4+), Ti(3+), Cr(3+), and possibly Cr(4+) in the Cr-doped thin films; Ti(4+), Ti(3+), V(3+), V(4+), and possibly V(5+) in the V-doped thin films; and Ti(4+), Ti(3+), Cr(3+), Cr(4+), V(3+), V(4+), and possibly V(5+) in the codoped thin films. While the thermodynamically stable valences Ti(4+), Cr(3+), and V(5+) would be expected to have formed, the presence of the nonequilibrium valences Ti(3+), Cr(4+), V(3+), and V(4+) is considered to have resulted from intervalence charge transfer for the Cr-doped and V-doped systems but from multivalence charge transfer (MVCT) for the codoped system. The latter phenomenon, which is introduced as a new conceptual term, describes the nature of the mutual exchange of electrons during valence changes of both dopant (Cr, V) and matrix (Ti) ions during annealing. In the present case, MVCT appears to be a transient metastable condition that acts during annealing, but subsequent UV irradiation can alter its effects.

“…The use of 4-sec-butyl-2- (-methylbenzyl) phenol (BAMBP) as a cesium extractant is discussed by Egan, et al (1964) and Ross and White (1964) also report the use of BAMBP. Crowther and Moore (1963) used 2thenoyltrifluoroacetone for liquid-liquid extraction of cesium.…”
