The challenge of converting biomass polysacharides into levulinic acid through heterogeneous catalytic processes
(John Wiley & Sons Ltd, 2020-03)
The differences between a biorefinery and an oil refinery are determined by the higher oxygen content of the biorefinery´s biomass, its high degree of functionalization, its low thermal stability, its polar components, ...
Energetic topography in adsorption onto heterogeneous surfaces
(Multi-Science Publishing, 2007-07)
The adsorption of gases onto heterogeneous surfaces has been reviewed, highlighting models capable of taking energetic topography effects into account. The basic ideas are contained in the fundamental Generalized Gaussian ...
Aligning biodiversity conservation and agricultural production in heterogeneous landscapes
(Ecological Society of America, 2020-04-14)
Understanding the trade-offs between biodiversity conservation and agricultural production has become a fundamental question in sustainability science. Substantial research has focused on how species’ populations respond ...
Middle Eocene deformation and sedimentation in the Puna- Eastern Cordillera transition (23°-26°S): Control by preexisting heterogeneities on the pattern of initial Andean shortening
(Geological Society of America, 2007-03)
The Quebrada de los Colorados Formation, at the north end of Calchaquí Valley in Salta Province, northwest Argentina, preserves evidence of syndepositional deformation since the middle Eocene (ca. 40 Ma) that includes (1) ...
Space and time dynamical heterogeneity in glassy relaxation. The role of democratic clusters
(IOP Publishing, 2009-05)
In this work we review recent computational advances in the understanding of the relaxation<br />dynamics of supercooled glass-forming liquids. In such a supercooled regime these systems<br />experience a striking dynamical ...
Spatial heterogeneity and woody species distribution in a Schinopsis balansae (Anacardiaceae) forest of the Southern Chaco, Argentina
(Universidad de Costa Rica, 1998)
XPS studies on the Cu(I,II)-polyampholyte heterogeneous catalyst: An insight into its structure and mechanism
(Elsevier Science, 2011-04-01)
A complex between Cu(II) and a polyampholyte synthesized from methacrylic acid, imidazole and ethyleneglycol diglycidyl ether was used as a heterogeneous catalyst for hydrogen peroxide activation and degradation of ...
