The effects of P-poisoning of CexZr1-xO2 on the transient oxygen storage and release kinetics
(2013)The present work reports on the investigation of the effects of chemical poisoning of CexZr1-xO2 solids by phosphorous (P) on the kinetics of oxygen storage and release (OSR) of the thus derived P-contaminated solids, as ...

Elemental composition of bone minerals in women with breast cancer treated with adjuvant tamoxifen
(1996)Oestrogen levels play a major role in conditioning the rates of bone changes in women. Tamoxifen is a synthetic oestrogen antagonist commonly used as an adjuvant therapy for breast cancer. The goal of the present study was ...

Experimental and theoretical studies on physico-chemical parameters affecting the solubility of phosphogypsum
(2009)Phosphogypsum is a waste by-product of the phosphate fertilizer industry, which is usually disposed in the environment because of its restricted use in industrial applications. Physico-chemical conditions existing in stack ...

New evidence that tamoxifen does not induce osteoporosis: A nuclear activation analysis and absorptiometry study
(1992)The possibility of increased risk for osteoporosis in breast cancer patients treated with tamoxifen was investigated. 26 patients aged 41-65 years without skeletal metastases were studied. All patients were treated with ...

Redox chemistry of sulphate and uranium in a phosphogypsum tailings dump
(2010)The present study aims to assess the effect of redox conditions existing within the tailings dump on the stability of phosphogypsum (e.g. sulphate reduction) and uranium(VI). Phosphogypsum sampling and in-situ measurements ...

Spatial dependence of ultrafast carrier recombination centers of phosphorus-implanted and annealed silicon wafers
(2002)In this letter, the spatial dependence of the carrier recombination centers induced in phosphorus-implanted and annealed silicon wafers have been examined. Ultrafast time-resolved reflectivity measurements of a set of ...

Suppression of the oxygen storage and release kinetics in Ce0.5Zr0.5O2 induced by P, Ca and Zn chemical poisoning
(2011)The present investigation concerns for the first time the understanding of the individual and combined effects of phosphorous with calcium or zinc deposited on a Ce0.5Zr0.5O2 solid followed by calcination in 20%O2/He at ...

Uranium chemistry in stack solutions and leachates of phosphogypsum disposed at a coastal area in Cyprus
(2008)The effect of the matrix composition (main constituents) on the concentration and chemical behavior of uranium in phosphogypsum stack solutions and leachates has been investigated. Solid and aqueous samples were taken from ...
