Investigation of the synthesis and properties of ternary V-Cu-Ce Oxides of Composition VxCuxCe1-2xO2

Attipa, Christothea; Theocharis, Charis R. (2009)

Aco-precipitation method has been used to prepare ternary mixed oxides based on ceria with the general formula VxCuxCe 1-2xO2, where x was varied between 0.05 and 0.45. The structural and surface properties as well as the ...

Modelling precipitation in Sweden using multiple step markov chains and a composite model

Lennartsson, J.; Baxevani, Anastassia; Chen, D. (2008)

In this paper, we propose a new method for modelling precipitation in Sweden. We consider a chain dependent stochastic model that consists of a component that models the probability of occurrence of precipitation at a ...

N2O decomposition over ceria-promoted Ir/Al2O3 catalysts: The role of ceria

Pachatouridou, E.; Papista, E.; Delimitis, Andréas; Vasiliades, Michalis A.; Efstathiou, Angelos M.; Amiridis, Michael D.; Alexeev, O. S.; Bloom, D.; Marnellos, G. E.; Konsolakis, M.; Iliopoulou, E. (2016)

The impact of CeO2 in the Al2O3-20wt% CeO2 support prepared by the co-precipitation method on the Ir particle size, morphology and oxidation state, and in turn on the deN2O catalytic activity (1000ppmN2O) of supported Ir ...

Precipitation of a water-soluble ABC triblock methacrylic polyampholyte: effects of time, pH, polymer concentration, salt type and concentration, and presence of a protein

Patrickios, Costas S.; Sharma, L. R.; Armes, S. P.; Billingham, N. C. (1999)

The solution behavior of a low molecular weight ABC triblock methacrylic polyampholyte with the structure (dimethylaminoethyl methacrylate)8-(methyl methacrylate)12-(methacrylic acid)16 was investigated by turbidimetry. ...

Protein complexation with acrylic polyampholytes

Patrickios, Costas S.; Hertler, Walter R.; Hatton, T. Alan (1994)

The interaction of dilute mixtures of proteins and ABC triblock methacrylic polyampholytes at different values of pH was investigated turbidimetrically. The onset of interaction was manifested by large changes in turbidity ...

A spatiotemporal precipitation generator based on a censored latent Gaussian field

Baxevani, Anastassia; Lennartsson, J. (2015)

A daily stochastic spatiotemporal precipitation generator that yields precipitation realizations that are quantitatively consistent is described. The methodology relies on a latent Gaussian field that drives both the ...
