New membranes for CO2 electrochemical reduction
Teixeira, António P. S.; Teixeira, Fátima C.; Rangel, C. M.; Messias, S.; Martins, R.; Mendes, J. M.; Reis Machado, Ana S.The use of CO2 as a valuable feedstock to obtain new useful fuels and materials, such as CO, alcohols, formic acid and hydrocarbons, has become an important research field that can contribute to valuable strategies in carbon resource utilization, such as the Electrochemical CO2 Reduction (ECR). The process is carried out in electrolyzers, which have a membrane as a key component to separate the two-half cells, ...
Facilitator factors to develop a healthy ageing Social Prescribing local system...
Ribeiro, S.; Lopes, J. O.; Santos, O.; Capitão, C.; Martins, R.; Virgolino, A.; Alarcão, V.; Nogueira, P.; Henriques, A.; Seabra, P.; Arriaga, M.Social Prescribing (SP) is an approach which aims of improving health and well-being and connecting patients to community services. Examples of these services include physical activity and cultural activities. Despite its benefits, SP has still not been fully implemented in Portugal. This case study is part of a larger study on Social Prescribing Local System (SPLS) implementation, which comprised a quantitativ...

Rational Approach to Design Gold Nanoparticles for Photothermal Therapy: the ef...
Ferreira-Gonçalves, T.; Nunes, D.; Fortunato, E.; Martins, R.; de Almeida, A.P.; Carvalho, L.; Ferreira, D.; Catarino, J.; Faísca, P.; Ferreira, H.A.Among the unique characteristics associated to gold nanoparticles (AuNPs) in biomedicine, their ability to convert light energy into heat opens ventures for improved cancer therapeutic options, such as photothermal therapy (PTT). PTT relies on the local hyperthermia of tumor cells upon irradiation with light beams, and the association of AuNPs with radiation within the near infrared (NIR) range constitutes an a...

Podcasting e as tendências de recentralização do áudio na mediação contemporânea
Paisana, M.; Martins, R.Este livro aprofunda o fenómeno da «Nova Comunicação», isto é, a forma como as ciências da comunicação contemporâneas estudam os fenómenos comunicativos. Em A Nova Comunicação argumenta-se que no atual modo de comunicação, a mediação, as dietas mediáticas, a matriz mediática e o sistema mediático atingem um novo nível de transformação. Transformação essa que leva ao modelo de comunicação contemporâneo - a «comu...
Screen-printed, flexible, and eco-friendly thermoelectric touch sensors based o...
Figueira, J.; Bonito, R. M.; Carvalho, J. T.; Vieira, E. M. F; Gaspar, C.; Loureiro, Joana; Correia, J. H.; Fortunato, E.; Martins, R.; Pereira, L.Despite the undoubtable interest in energy conversion, thermoelectric (TE) materials can be approached from a temperature-sensitive perspective, as they can detect small thermal stimuli, such as a human touch or contact with cold/hot objects. This feature offers possibilities for different applications one of them being the integration with scalable and cost-effective, biocompatible, flexible, and lightweight t...
Concept paper on novel radio frequency resistive switches
Kiazadeh, A.; Deuermeier, J.; Carlos. E.; Martins, R.; Matos, S.; Cardoso, F. M.; Pessoa. L.For reconfigurable radios where the signals can be easily routed from one band to another band, new radio frequency switches (RF) are a fundament. The main factor driving the power consumption of the reconfigurable intelligent system (RIS) is the need for an intermediate device with static power consumption to maintain a certain surface configuration state. Since power usage scales quadratically with the RIS ar...
Da lei à prática: contributo da intervenção precoce para o desenvolvimento das ...
Carvalho, O.; Neves, M.; Martins, R.; Pascoinho, J.; Galinha, Sónia Maria Gomes AlexandreO estudo "Da Lei à Prática: Indicadores para a Inclusão", pretende apresentar os resultados da aplicação de um inquérito por questionário adaptado do “Índex para a Inclusão” de Booth e Ainscow (2002) em que se mediram um conjunto de indicadores para a inclusão. O inquérito foi aplicado no grupo “Espaço 54 – Grupo de Apoio à Educação Inclusiva” e responderam 155 elementos. O instrumento constitui um recurso para...
