Circularity Micro-Indicators to Building and Construction Sector: Plastic Produ...

Matos, J.; Martins, C.I.; Simões, C.L.; Simões, R.

The civil construction sector has been a large contributor for the continuous global increase in the consumption of plastics. However, while the properties of plastics make them very suitable for several civil construction applications, their sustainability is a concern, mostly because current approaches for design and manufacturing do not properly consider their entire lifecycle and end-of-life management. The...

Matos, J.; Martins, C.I.; Simões, C.L.; Simões, R.

O setor da Construção Civil é um dos maiores contribuintes da atualidade para o aumento continuo no consumo global dos plásticos. No entanto, apesar das propriedades dos plásticos se adequar a várias aplicações neste setor, a sua sustentabilidade é uma preocupação, principalmente porque as aplicações plásticas atuais são projetadas e fabricadas sem uma prudente reflexão sobre o seu ciclo de vida e a sua gestão ...

In situ Trametes versicolor laccase biocathode performance assessment in dual-c...

Ottoni, Cristiane; do Valle Trotta, Caterina; Martins, Gilberto; Matos, J.; Maiorano, Alfredo Eduardo; Brito, António G.; Peixoto, L.

White-rot fungi (WRF) synthesize ligninolytic extracellular oxidative enzymes such as laccase (Lcc), which has been described as one of the most interesting types of redox enzymes that can improve microbial fuel cell (MFC) performance. Therefore, and in order to test that performance, WRF Trametes versicolor MUM 04.100 was immobilized in nylon sponge and fixed in the MFC cathode chamber, while Lcc activity, bio...


Projeto LouMu - Muografia no Lousal

Teixeira, Pedro; Blanco, A.; Caldeira, Bento; Tomé, B.; Matos, J.; Borges, José Fernando; Cazón, L.; Lopes, L.; Afonso, L.; Pinto, M.; Pimenta, M.

A viabilidade da muografia como técnica de sondagem tem sido demonstrada em diversos trabalhos ao redor do mundo, desde os seus primeiros passos. A muografia com muógrafos em ambiente subterrâneo tem um lado fácil devido à ausência da radiação de fundo, mas, por outro lado, o fluxo de muões é muito menor em comparação com o que é medido na superfície. É uma questão de condições geológicas e subterrâneas, deteto...


Muography in the university and in the museum

Afonso, L.; Alexandre, I.; Andringa, S.; Assis, P.; Blanco, O.; Bezzeghoud, M.; Borges, J.; Caldeira, B.; Cazon, L.; Costa, J.; Dobrilla, P.; Duarte, M.

The LouMu team joins together specialists in particle detectors and in cosmic ray analyses, geophysicists and science communicators to muograph an underground gallery of an old mine, now open to visitors of a science museum. The muon telescope is made of Resistive Plate Chambers (RPCs) developed to operate stably and with low consumption at remote locations, and it has been tested in the Coimbra University, bef...


A New Concept of Jig Rotary Holder System for 3-Axis CNC Milling Machine Operat...

Silva, Francisco J. G.; Campilho, R.D.S.G.; Sousa, Vitor F. C.; Coelho, Luis F. P.; Pinto Ferreira, Luís; Pereira, Maria Teresa; Matos, J.

This study aims to develop a new jig holding system that is able to be controlled by a Computer Numeric Control (CNC) installed on three-axis machining centers, which can drastically improve the productivity in machining operations, enabling the machining of unparallel plans in the same setup. An action research methodology was adopted for this work, which, through a practical approach, intends to generate tran...


Bioprospection, study and application of bioactive compounds from microalgae an...

Matos, J.

Microalgae and seaweeds, a natural source of highly valuable bioactive compounds, are considered one of the most promising and innovative sources of novel functional foods that can favourably affect human health. This study focused on the bioprospection of bioactive compounds from freeze-dried biomasses and extracts of selected microalgae (Chlorella vulgaris, Arthrospira platensis, Isochrysis galbana, Tetraselm...


Tale of Two Cities: How Nature-Based Solutions Help Create Adaptive and Resilie...

Cui, Mengmeng; Ferreira, Filipa; Fung, Tze Kwan; Matos, J.

Nature-based solutions (NbS) are increasingly recognized as viable tools for sustainable urban water management. This article explores the implementation of NbS in two distinct cities, Singapore and Lisbon, to demonstrate that NbS can work in very different contexts and spark new thoughts on the urban–nature relationship and to identify commonalities that drive and enable the implementation of NbS in different ...


Food system sustainability metrics: Policies, quantification, and the role of c...

Matos, J.; Lopes, R. J.

The rise of global attention toward sustainability and sustainable development (SD) has provided increased incentives for research development and investment in these areas. Food systems are at the center of human needs and global population growth sustainability concerns. These drives and the need to provide quantified support for related investment projects led to the proliferation of sustainability metrics a...

Bioactive and nutritional potential of Alaria esculenta and Saccharina latissima

Afonso, C.; Matos, J.; Guarda, I.; Gomes-Bispo, A.; Gomes, R.; Cardoso, C.; Gueifão, S.; Delgado, I.; Coelho, Inês; Castanheira, Isabel; Bandarra, N.M.

The brown seaweed species Alaria esculenta and Saccharina latissima are commercial edible resources in Norway. There are knowledge gaps regarding these species. Accordingly, they were characterized and their bioactivity and bioaccessibility evaluated. The fatty acid (FA) analysis revealed anω-3/ω-6 ratio of almost 2 in A. esculenta vs 1 in S. latissima. The FAs 18:4ω-3 (stearidonic acid) and 20:5ω-3 (eicosapent...
