Nanostructured polymeric coatings based on chitosan and dopamine-modified hyalu...

In a marine environment, specific proteins are secreted by mussels and used as a bioglue to stick to a surface. These mussel proteins present an unusual amino acid 3,4-dihydroxyphenylalanine (known as DOPA). The outstanding adhesive properties of these materials in the sea harsh conditions have been attributed to the presence of the catechol groups present in DOPA. Inspired by the structure and composition of t...

Biomimetic miniaturized platform able to sustain arrays of liquid droplets for ...

The development of high-throughput and combinatorial technologies is helping to speed up research that is applicable in many areas of chemistry, engineering, and biology. A new model is proposed for flat devices for the high-throughput screening of accelerated evaluations of multiplexed processes and reactions taking place in aqueous-based environments. Superhydrophobic (SH) biomimetic surfaces based on the so-...

Miniaturized droplets-based microarray of chemical and biological high-throughp...

Publicado em "Journal of Tissue Engineering and Regenerative Medicine, vol. 7, supp. 1 (2013) ; The development of high-throughput and combinatorial technologies is helping to speed up research that is applicable in many areas of chemistry, engineering and biology. We propose a simple, versatile high-efficient and new superhydrophobic platform, which permits to arrange of quasi-spherical aqueous-based droplets...

Polymeric layer-by-layer films composed by natural polymers and based on the ad...

Publicado em "Journal of Tissue Engineering and Regenerative Medicine", vol. 7, supp. 1 (2013) ; Some marine species, such as mussels, can strongly attach themselves to rocks in the diffficult conditions of the sea. In fact, marine mussels secrete adhesive proteins that show a high adhesion to both inorganic and organic surfaces in aqueous environments. These proteins have an amino acid designated as 3,4-dihyd...

Nos trabalhos em lingüística encontram-se recorrentemente análises que incidem sobre formas verbais que, conjuntamente com o Sintagma Nominal e ou com o Sintagma Preposicional, constituem entidades que se caracterizam por mostrarem algumas formas de solidariedade, nomeadamente ao nível da variação das marcas gramaticais que as constituem. Um caso paradigmático destas ocorrências é o das expressões fixas (ou fra...

Determinação e cognição

Os estudos de lingüística, ao mesmo tempo que descrevem e analisam as formas disponíveis em cada sistema, assentam essa descrição em propostas metateóricas de forma a delimitar uma compreensão sobre o funcionamento das línguas naturais. Ao definir um conjunto de hipóteses, a lingüística constrói os mecanismos abstractos que regulam a produção e o reconhecimento de formas. No quadro teórico onde me situo (Teoria...
