It is well-known that heavy metals brought by intensive pig slurry applications accumulate in the soil; because of their potential impact on the environment, studying their behaviour is of utmost interest. The Solepur process has been developed in Brittany (France) where pig farming causes serious environmental problems; it enables the soil to be used as a(More)

Experimental structure functions for (Na(2)O)(0.35) [(P(2)O(5))(1 - x)(B(2)O(3))(x)](0.65) glasses, where x = 0.0, 0.2, 0.4, 0.6, 0.8 and 1.0, have been measured by high-energy x-ray diffraction up to wavevectors of 28 Å( - 1) to obtain atomic pair distribution functions with high real space resolution. The experimental diffraction data have been used to(More)
Experimental structure functions for (Na2O)0.35[(P2O5)1−x(B2O3)x ]0.65 glasses, where x = 0.0, 0.2, 0.4, 0.6, 0.8 and 1.0, have been measured by high-energy x-ray diffraction up to wavevectors of 28 Å −1 to obtain atomic pair distribution functions with high real space resolution. The experimental diffraction data have been used to guide constrained reverse(More)
Using density-functional molecular dynamics simulations we analyzed the cooling-rate effects on the physical properties of GeS2 chalcogenide glasses. Liquid samples were cooled linearly in time according to T (t) = T0 − γt where γ is the cooling rate. We found that our model leads to a promising description of the glass transition temperature Tg as a(More)
