In the present work, new kinetics to describe the creaming stability of oil-in-water emulsions determined by backscattering measurements （BS） is proposed. The emulsions assayed exhibited a different backscattering profiles regarding creaming destabilization hyperbolic and sigmoid one. Hyperbolic behavior can be described by a second order kinetics, where k_h could be equaled to a rate constant that describes the creaming process and its values would indicate the stability of emulsions. While for the sigmoid BS pattern, kinetics with two terms, is adequate to describe the creaming process in contrast to kinetics previously reported in the literature. The kh value has the same meaning as before, and ks indicates the delaying effect on the creaming rate.

Perovskites as host structures of cations were used in order to generate in situ active and stable catalysts for ethanol steam reforming. For this purpose,La_(1-x)Mg_xAl_(1-y)Ni_yO_3(x = 0.1; y = 0,0.1,0.2,0.3) perovskites were synthetized by the citrate *** segregation is evident for a substitution level higher than 0. 2. The segregation of Ni as NiO generated species interacts with different metal-support after the reduction step. The y = 0.1 catalyst presents the highest H_2 yield value about 85% during reaction time,with low mean values of CH_4 and CO selectivities of 3.4% and 11%,respectively and a low carbon formation. The better performance of y = 0.1 catalyst could be attributed to the minor proportion of segregated phases,thus a controlled expulsion of Ni is successfully reached.

The 2-oxoglutarate and Fe （ll）-dependent dioxygenase （2OGD） superfamily includes oxidative enzymes with an active site con- taining two histidines and （in most cases） one aspartic or glutamic acid residue. This conserved motif is termed the 2-His-1-carboxylate facial triad, chelates iron, and is housed within a double-stranded β-helix fold, also known as the DSBH, jelly-roll, cupin, or Jumonji C fold （Martinez and Hausinger, 2015）. The reactions catalyzed by 2OGDs （also called 2ODDs, 2ODQs, and 2OGXs） include but are not limited to demethylation, demethylenation, hydroxytation, halogenation, desaturation, ring cleavage, ring closure, and epimerization （Farrow and Facchini, 2014）.
