Dois em Um: Educação Visual de Todos como Pilar da Sustentabilidade do Patrimón...
Oliveira, ElisabeteBy this Research, we verify the Visual Education double structural capability: (1) in the core-Currículum of everyone until adolescence; (2) in its corpus of projects, assuming the value of Immaterial Cultural Patrimony. In (1), we document pioneer Good Practices, for environment improvement through Visual Art-Design Education, in Eco-compatibilization with natural and built environment emergence. In (2), we va...
Application of a risk management methodology in industrial projects: a case stu...
Oliveira, Elisabete; Tereso, Anabela Pereira; Santos, ClaúdioAll projects are subjected to varying degrees of uncertainty and risk because they are unique. Risk management of a set of specialties that make up an industrial project is one of the most difficult challenges. It is up to the project manager to develop the ability to predict events, seize opportunities or assess threats, allowing mitigation measures to be implemented in a timely manner. The main objective of t...
Convocarte, nº5 (Dez. 2017): Arte e Activismo Político: Perspectivas da Históri...
Dias, Fernando; Cruzeiro, Cristina Pratas; Harvey, Mark; Alves, Margarida Brito; Elias, Helena; Valente, Catarina; Braz, Ivo; Ramos Guadix, Juan CarlosDepois do editorial anterior, em reflexões sobre o lugar do saber e da verdade na cultura actual, enquanto problematização política, assumimos a estranheza por a Universidade estar a deixar de ser um lugar crítico e, portanto, político. Este editorial, do segundo volume com dossier temático sobre Arte e Activismo, propõe-se, em continuidade, a reflectir sobre o lugar da Universidade, atendendo às suas recentes ...
An unusual highly emissive water-soluble iridium lissamine-alanine complex and ...
Oliveira, Elisabete; Santos, Sérgio M.; Núñez, Cristina; Capelo, José Luis; Lodeiro, CarlosThe interaction of iridium(III) with a new lissamine rhodamine B sulfonyl derivative, bearing alanine as a building block, (1) with an orange emission in water results in a green highly emissive Ir@1 complex at room temperature. The new Ir@1 complex can sense the toxic Hg2+ metal ion and cysteine. Based on such properties, a new sophisticated molecular logic gate with three inputs was designed.

From yellow to pink using a fluorimetric and colorimetric pyrene derivative and...
Pinheiro, Daniela; Castro, Catherine S. de; Melo, J. Sérgio Seixas de; Oliveira, Elisabete; Nuñez, Cristina; Fernández-Lodeiro, Adrián1st International Caparica Conference on Chromogenic and Emissive Materials; A new simple and multifunctional fluorescent probe based on pyrene linked through an imine bond to a hydroxyphenol unit was synthesised, fully characterized and investigated in solution. Additionally, its behaviour in the presence of several ions (H+, Zn2+, Cd2+, Cu2+, Ni2+, Pb2+, Fe2+, Hg2+ and Al3+) was investigated in CH2Cl2. It was...
Cyanide and fluoride colorimetric sensing by novel imidazo-anthraquinones funct...
Batista, Rosa Maria Ferreira; Oliveira, Elisabete; Costa, Susana P. G.; Lodeiro, Carlos; Raposo, M. Manuela M.Novel imidazo-anthraquinones functionalized with indole and carbazole have been synthesised and characterised and their evaluation as colorimetric chemosensors was carried out in acetonitrile as well as in acetonitrile/H2O (97:3) in the presence of several anions such as F-, Cl-, Br-, I-, CN-, NO3-, ClO4-, AcO-, BzO-, NO3-, ClO4-, HSO4- and H2PO4-. Additionally, their behaviour in the presence of H+ and OH- was...
Rhodamine-Appended Bipyridine: XOR and OR Logic Operations Integrated in an Exa...
Nunez, Cristina; Santos, Sergio M.; Oliveira, Elisabete; Santos, Hugo M.; Capelo, Jose Luis; Lodeiro, CarlosA new bipyridyl derivative 1 bearing rhodamineB as visible fluorophore was designed, synthesized and characterized as a fluorescent and colorimetric sensor for metal ions. Interaction with Cu2+, Zn2+, Cd2+, Hg+, and Hg2+ ions was followed by UV/Vis and emission spectroscopy. Upon addition of these metal ions, different colorimetric and fluorescent responses were observed. Off-on-off (Cu2+, Zn2+, and Hg2+) and o...
Columnar discotic Pt(II) metallomesogens as luminescence multifunctional materi...
Cuerva, Cristian; Campo, Jose A.; Ovejero, Paloma; Rosario Torres, M.; Oliveira, Elisabete; Santos, Sergio M.; Lodeiro, Carlos; Cano, MercedesA new family of Pt(II) luminescent metallomesogens based on dicatenar pyridylpyrazolate ligands [Pt(pz(R(n,n)py))(2)] (R(n,n) = C6H3(OCnH2n+1)(2), n = 4-18) has been prepared, and their mesomorphic and photophysical properties are described. The compounds were isolated as red (n = 4-8) or yellow (n = 10-18) solids at room temperature, but the first ones were converted to yellow crystals by slow evaporation of a...
Corrole and Corrole Functionalized Silica Nanoparticles as New Metal Ion Chemos...
Santos, Carla I. M.; Oliveira, Elisabete; Fernandez-Lodeiro, Javier; Barata, Joana F. B.; Santos, Sergio M.; Faustino, M. Amparo F.Corrole macrocycles are very appealing dyes for incorporation into light harvesting devices. This work shows the sensorial ability of 5,10,15-tris(pentafluorophenyl)corrole 1 and its monoanionic species toward Na2+, Ca2+, Cu2+, Cd2+, Pb2+, Hg2+, Ag+, and Al3+ metal ions in toluene and acetonitrile. The photophysical studies toward metal ions were carried out by absorption and emission spectroscopy. From all met...
