What can explain the great success of this and other invasive ants? It is known that social insects (bees, ants, wasps and termites) live in colonies in which all members cooperate in the work. Natural conditions in the various colonies compete for the same resources and...
Organisation of polyfluorinated platinum nanoparticles
Metal nanoparticles are of great interest because of their size at nanometer scale which provides them with new properties, different from those of bulk metal. In this work some materials formed by small platinum nanoparticles...
New recoverable metathesis catalysts
The preparation of several organic-inorganic hybrid materials by sol-gel process derived from Hoveyda-type monomers is described. One of them presents a nitro group at the para position with respect to the alkoxy moiety. These materials were treated with Grubbs catalysts to generate the...
