Reversible Topochemical Exsolution of Iron in BaFe2+2(PO4)2

24.10.2014 | Rénald David, Houria Kabbour, Dmitry Filimonov, Marielle Huvé, Alain Pautrat, Olivier Mentré, Angewandte Chemie International Edition, 2014

Abstract BaFe2+2(PO4)2 was recently prepared and identified as the first 2D‐Ising ferromagnetic oxide with an original reentrant structural transition driven by high‐spin Fe2+ ions arranged in honeycomb layers. Both long‐term air exposure and moderate temperature (T>375 °C) leads to ...

Oxidation behavior of chromium‐rich Fe‐based alloys containing HfC carbides at 1100 °C

24.10.2014 | E. Conrath, P. Berthod, Materials and Corrosion, 2014

Three HfC‐containing iron‐based alloys were successfully elaborated by foundry. The alloys, all containing 27 wt% Cr, 0.25 or 0.50 wt% C and 4 to 6 wt% Hf, are composed of a dendritic matrix and of HfC carbides of two types: pre‐eutectic blocky carbides and interdendritic script‐like HfC ...

Impact of oxygen transport properties on the kinetic modeling of polypropylene thermal oxidation. II. Effect of oxygen diffusivity

23.10.2014 | Alexandre François‐Heude, Emmanuel Richaud, Alain Guinault, Eric Desnoux, Xavier Colin, Journal of Applied Polymer Science, 2014

ABSTRACT The kinetic model, established in a previous article (François‐Heude et al., J. Appl. Polym. Sci., in press) to predict the homogeneous oxidation in iPP films typically thinner than 100 µm, is now extended to simulate the oxidation profiles in thicker plates by coupling the oxygen ...

CexOy– (x = 2–3) + D2O Reactions: Stoichiometric Cluster Formation from Deuteroxide Decomposition and Anti-Arrhenius Behavior

21.10.2014 | Jeremy A. Felton; Manisha Ray; Sarah E. Waller; Jared O. Kafader; Caroline Chick Jarrold, Journal of Physical Chemistry A, 2014

Reactions between small cerium oxide cluster anions and deuterated water were monitored as a function of both water concentration and temperature in order to determine the temperature dependence of the rate constants. Sequential oxidation reactions of the CexOy– (x = 2, 3) suboxide cluster anions ...

Impact of oxygen transport properties on polypropylene thermal oxidation, part 1: Effect of oxygen solubility

18.10.2014 | Alexandre François‐Heude, Emmanuel Richaud, Alain Guinault, Eric Desnoux, Xavier Colin, Journal of Applied Polymer Science, 2014

ABSTRACT A general kinetic model is proposed to describe the polypropylene thermal oxidation of thin polypropylene films in a wide range of temperatures (from 60 to 200°C) and oxygen partial pressures (from 0.02 to 5 MPa) using a single set of parameters. This model was calibrated with several ...
