Jimena A. Olmos-Asar,Marcelo M. Mariscalive generally covariant integration measure densities (volume elements) defined in terms of auxiliary antisymmetric tensor gauge fields. Here gravity couples in a non-conventional way to two distinct scalar fields providing a unified Lagrangian action principle description of: (i) the evolution of b

Oscar A. Oviedo,Ezequiel P. M. Leivaironmental consequences. Biorefinery development reports two important goals in the transition towards a bio-based economy: (i) the displacement of fossil-based products by biomass-based ones and (ii) the setting up of a strong bio-based industry. In this sense, research is being addressed into bio-

Experimental and Simulated Electron Microscopy in the Study of Metal Nanostructures a direct way the structure and composition of nanostructures at a sub-Angstrom resolution. Specifically, with the use of ultra-high resolution high angular annular dark field scanning transmission electron microscopy (HAADF-STEM) in the study of metal nanoalloys, it is now possible to describe in d

Density-Functional Theory of Free and Supported Metal Nanoclusters and Nanoalloysst in basic science as well as in current technology where they find many applications for their unique properties: from chemical sensing (artificial noses) to heterogeneous catalysis, from magnetic recording to opto-electronic devices. First-principles theoretical approaches (i.e., approaches based

Closed-Shell Metal Clusters evolve in the intermediate size regime between molecular species and solids, and trying to create building blocks for new materials . The latter requires clusters, and cluster assemblies, that are stable under normal conditions. This is challenging. Taking the viewpoint of the solid state, metal

Spin-Fluctuation Theory of Cluster Magnetismory overview of the experimental situation, we present the theoretical framework, which is based on a Hubbard–Stratonovich functional-integral formulation of the corresponding canonical and grand-canonical equilibrium partition functions. The theory is applied to Fe, Co, and Ni clusters by using the
