Abstract:

Covalent Organic Frameworks (COFs) are a novel class of highly stable, purely organic crystalline frameworks made of molecular building blocks. For example, the condensation of boronic acids with appropriate polyols in principle allows the design of precisely controllable structures since their chemical and physical properties can be easily tuned through the selection of the building blocks. The young research field of COFs has attracted scientists due to their extraordinary and versatile properties, however, strategies to control the topology and the properties of the backbone as well as the

Abstract:

The two main subjects of this thesis are the realization of supramolecular self-assembled monolayers at surfaces and the formation of surface-supported two-dimensional covalent organic frameworks. Both topics, albeit different, yield long-range ordered open-pore networks with quite different stabilities, depending on the strength and type of bonds holding them together. The surface of choice is mainly graphite, which is considered an inert substrate. Graphite yields pristine clean, very large and flat surfaces when cleaved, facilitating the observation in real space of the molecular networks a

Abstract:

There is an increasing necessity for the pharmaceutical industry to develop enantiomerically pure drugs. Up till now, production of enantiomerically pure molecules has been provided by harvesting them from plants or utilising homogeneous catalysis and biocatalysis. None of these methods are efficient means of production, and attention is now being directed towards heterogeneous enantioselective catalysis as the preferred technique. This is on account of the high product yield and ease of separation of catalyst from the reaction mixture. Over the past few decades, a great deal of research has b

For many applications of industrial relevance, solids providing enhanced porosity such as activated carbons or zeolites have been the key drivers of progress in the past century. Albeit these materials marked an entire era of research, scientists have contributed immense effort to mimic porosity in an artificial way.

Abstract:

Dissertação de mestrado integrado em Engenharia Biológica (área de especialização em Tecnologia do Ambiente)<br>Biotoxins are metabolites produced by some microalgae species that can reach high concentrations when a massive proliferation of them occur. These kind of compounds are especially dangerous when concentrated in digestive glands of seafood. In general, biotoxins do not affect mollusks, however, the presence of biotoxins turns the mollusks unappropriated for human consumption. In this way, it is very important to improve monitoring methods of biotoxins in water in order to generate an
