Study of highly efficient molecules to improve organic synthesis
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.
How did heavy metal get to the road?
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 for remote environmental monitoring
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...
"Computerized" nanomolecules
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...
New on-line analyser of harmful composes in biogas
Researchers of the Group of Waste Gas Treatment at the Department of Chemical Engineering of the UAB have developed an analyser for the detection of sulfide ion in liquid and hydrogen sulfide in gas samples, especially designed to be used in the control of biofílters...
Electroactive nanoparticles: a better view of environment and DNA
Nowadays the search for better and cheaper analysis techniques is an important issue in genetics and environmental sciences. This thesis is centered on two objectives: application of electrochemical stripping analysis, and development of new DNA and...
New molecules with ionic liquid crystal properties
Ionic liquid crystals are a class of liquid crystals composed of ions. These compounds are interesting due to their properties as liquid crystals and to their ion conductivity. In this work we have prepared two new families of molecules which show these characteristics.
Intermatrix synthesis of metal nanoparticles
Meta nanoparticles (MNPs) have interesting applications due to their special chemical and physical properties. This work describes the development of a polymer stabilized with MNPs (PSMNPs), using the membranes of ionic exchange as a nanoreactor.
