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...
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...
Using several analytical and spectroscopic technologies, the structure of diverse complexes of Pt(II) with pyrazole ligands has been determined. The results of these structural analyses have been obtained from a series of NMR studies of
Ligands are either atoms, ions, or molecules that bond to a central metal, generally involving formal donation of one or more of its electrons. In this research, scientists have synthesized and characterized two new ligands N-pirazole and...
Based on a combined experimental and computacional study, authors of this work analized the effectiveness of some groups of molecules derivated from pirazol, used as precatalists in organic synthesis developed by Heck reactions.
Roadside sediments, in which high amounts of sediments have been detected, are an environmental concern of great interest due to the possible transmission of their pollutants from traffic activities and road maintenance to humans and environment. This work analyzes leaching tests applied to...
Electronic tongues are systems capable of providing chemical analytical information in real time and in-situ. This study successfully explores the possibility of using different potentiometric electronic tongues in environmental monitoring applications with remote...
Most of the materials and functional systems developed by nanotechnology are based on molecules. An example of these are the [2]rotaxanes, which present physical and chemical properties potentially useful for Informatics and Medicine. In this thesis, a powerful computational strategy is outlined and...
