Functionalization of nickel nanowires with a fluorophore aiming at new probes f...
Pinheiro, Paula C.; Sousa, Célia T.; Araujo, João P.; Guiomar, A. J.; Trindade, TitoThis work reports research on the development of bimodal magnetic and fluorescent 1D nanoprobes. First, ferromagnetic nickel nanowires (NiNW) have been prepared by Ni electrodeposition in an anodic aluminum oxide (AAO) template. The highly ordered self-assembled AAO nanoporous templates were fabricated using a two-step anodization method of aluminum foil. The surface of the NiNW were then modified with polyethy...

Structural behaviour of log timber walls under lateral in-plane loads
Branco, Jorge M.; Araújo, João P.The present works intends to represent a further step in the knowledge of timber loghouses through an experimental approach, from which only few information is available. The main part of the experimental work is based on in-plane static tests conducted on timber log walls with distinct transversal stiffness, two vertical compression levels and different values of slenderness. Monotonic and cyclic tests were pe...
Lateral resistance of log timber walls subjected to horizontal loads

Comportamento sísmico de um sistema log-house
Araújo, João P.; Branco, Jorge M.O presente trabalho pretende contribuir para o conhecimento do sistema construtivo “Log-house” através de uma vasta análise experimental e de análises numéricas. A campanha experimental, realizada previamente, teve por objectivo de estudar o comportamento no plano das paredes em troncos de madeira quando sujeitas a acções monotónicas e cíclicas, de acordo com a EN 12512:2001. Apresenta-se ainda um caso de estud...
Comportamento sísmico de um sistema log-house
Araújo, João P.Dissertação de mestrado (ciclo de estudos integrado em Engenharia Civil) ; A madeira, enquanto material de construção, já ocupou no passado um lugar de destaque. Contudo, o aparecimento de outros materiais, como o aço e o betão, levou quase ao seu abandono total para fins estruturais. Excepção a esta tendência viveu-se nos países do Norte e Centro da Europa, sendo exemplo o sistema construtivo “Log-house”. Est...
