CORROSION RESISTANCE OF CERIUM-CONVERSION COATINGS FORMED FROM CERIUM(III) SALTS ON ALUMINIUM ALLOY 7075-T6

open access: yesStudia Universitatis Babes-Bolyai Chemia, 2020
Cerium conversion coatings were explored as an alternative to chromate conversion coatings for corrosion protection of aluminium alloy 7075-T6. Conversion coatings were formed in a conversion bath of 0.05 M cerium salt and 0.25 M hydrogen peroxide at ...

Modulation of Cerium Carbonate Crystal Growth by Polyvinylpyrrolidone using Density Functional Theory

open access: yesActa Chimica Slovenica, 2022
Cerium carbonate crystal morphology is predicted using density functional theory (DFT) simulations in this paper. In the nucleation phase, the ketone group in polyvinylpyrrolidone (PVP) will preferentially bind to Ce3+ to form complexes and provide ...

Monometallic cerium layered double hydroxide supported Pd-Ni nanoparticles as high performance catalysts for lignin hydrogenolysis [PDF]

open access: yes, 2020
Monometallic cerium layered double hydroxides (Ce-LDH) supports were successfully synthesized by a homogeneous alkalization route driven by hexamethylenetetramine (HMT).

Cerium oxide nanoparticles: properties, biosynthesis and biomedical application

open access: yesRSC Advances, 2020
Nanotechnology is the branch of science which deals with particles ranging between 1–100 nm. These particles are called nanoparticles, and they exhibit unique electronic, optical, magnetic, and mechanical properties, which make them different from the ...

How Cerium and Lanthanum as Coproducts Promote Stable Rare Earth Production and New Alloys

open access: yesJournal of Sustainable Metallurgy, 2022
The largest outputs of rare earth mining are the low-value byproducts cerium and lanthanum, which burden rare earth supply chains because they must be separated from more desirable rare earths used in magnet production.

Influence of the Cerium Concentration on the Corrosion Performance of Ce-doped Silica Hybrid Coatings on Hot Dip Galvanized Steel Substrates

open access: yesInternational Journal of Electrochemical Science, 2013
The aim of this work was to investigate the effect of the cerium concentration on the morphology and anticorrosion performance of cerium-silane hybrid coatings on hot dip galvanized (HDG) steel substrates.

Vibrational and electronic entropy of β-cerium and γ-cerium measured by inelastic neutron scattering [PDF]

open access: yes, 2002
Time-of-flight (TOF) inelastic neutron-scattering spectra were measured on β-cerium (double hcp) and γ-cerium (fcc) near the phase-transition temperature. Phonon densities of states (DOS) and crystal-field levels were extracted from the TOF spectra.

Doniach diagram for ordered, disordered and underscreened Kondo lattices [PDF]

open access: yes, 2007
The Doniach's diagram has been originally proposed to describe the competition between the local Kondo effect and the intersite RKKY interactions in cerium compounds.

Synthesis and catalytic performance of CeOCl in Deacon reaction [PDF]

open access: yes, 2013
Surface chlorinated CeO2 is an efficient material for HCl oxidation, which raises the question whether an oxychloride phase could be also active in the same reaction.
