Bio-nanohybrid catalysts based on L-leucine immobilized in hydrotalcite and their activity in aldol reaction
(2016-06-05)
Article
Accés obertNanohybrid materials based on L-leucine (L-Leu) and hydrotalcites (HT) were prepared by the ion exchange and reconstruction method, under mild synthesis conditions. The location, amount and the form of the immobilized L-Leu ... -
Dielectric, calorimetric and mesophase properties of 1 ''-(2 ',4-difluorobiphenyl-4 '-yloxy)-9 ''-(4-cyano-biphenyl-4 '-yloxy) nonane: an odd liquid crystal dimer with a monotropic mesophase having the characteristics of a twist-bend nematic phase
(2014-10-21)
Article
Accés restringit per política de l'editorialThis paper reports a novel liquid crystal phase having the characteristics of a twist-bend nematic phase formed by a non-symmetric ether-linked liquid crystal dimer. The dimer 1 ''-(2',4-difluorobiphenyl-4'-yloxy)-9 ... -
Dispersion of gamma-alumina nano-sized spherical particles in a calamitic liquid Crystal. Study and optimization of the confinement effects
(2014-03-01)
Article
Accés obertWe report an experimental study on confined systems formed by butyloxybenzylidene octylaniline liquid crystal (4O.8) + gamma-alumina nanoparticles. The effects of the confinement in the thermal and dielectric properties ... -
Dynamic characterization of crystalline and glass phases of deuterated 1,1,2,2 tetrachloroethane
(2015-10-07)
Article
Accés obertA thorough characterization of the gamma, beta, and glass phases of deuterated 1,1,2,2 tetrachloroethane (C2D2Cl4) via nuclear quadrupole resonance and Molecular Dynamic Simulations (MDSs) is reported. The presence of ... -
Percolation thresholds in chemical excitable media.
(American Physical Society, 1998-08-31)
Article
Accés obertThe behavior of chemical waves advancing through a disordered excitable medium is investigated in terms of percolation theory and autowave properties in the framework of the light-sensitive Belousov-Zhabotinsky reaction. ... -
The influence of nano-architectured CeOx supports in RhPd/CeO2 for the catalytic ethanol steam reforming reaction
(2015-09-15)
Article
Accés obertThe ethanol steam reforming (ESR) reaction has been tested over RhPd supported on polycrystalline ceria in comparison to structured supports composed of nanoshaped CeO2 cubes and CeO2 rods tailored toward the production ... -
