Of all the different areas in computational chemistry, density functional theory (DFT) enjoys the most rapid development. Even at the level of the local density approximation (LDA), which is computationally less demanding, DFT can usually provide better answers than Hartree-Fock formalism for large systems such as clusters and solids. For atoms and molecules, the results from DFT often rival those obtained by ab initio quantum chemistry, partly because larger basis sets can be used. Such encouraging results have in turn stimulated workers to further investigate the formal theory as well as...

hemistry is the science about breaking and forming of bonds between atoms. One of the most important processes for organic chemistry is breaking bonds C–H, as well as C–C in various compounds, and primarily, in hydrocarbons. Among hydrocarbons, saturated hydrocarbons, alkanes (methane, ethane, propane, hexane etc. ), are especially attractive as substrates for chemical transformations. This is because, on the one hand, alkanes are the main constituents of oil and natural gas, and consequently are the principal feedstocks for chemical industry. On the other hand, these substances are known ...

La editorial de Ecologistas en Acción inaugura la colección Socioayuda con ’Sal de la máquina’, del madrileño afincado en Barcelona Sergio Legaz, con portada e ilustraciones del dibujante Miguel Brieva. "En un mundo como el actual, construido en su mayor parte por las mismas máquinas, tener un conocimiento de la Máquina es el poder más grande que existe”. Por primera vez en la historia de la tecnología, un objeto ha colonizado completamente nuestro espacio vital, interfiriendo en todas nuestras actividades cotidianas. Los smartphones o ’teléfonos inteligentes’ se han...
