Green exfoliation of 2D nanomaterials using cyrene as a solvent
Moreira, Pedro; Mendes, João; Calmeiro, Tomás; Nunes, Daniela; Carvalho, David; Kelly, Adam; Águas, Hugo; Fortunato, Elvira; Martins, RodrigoLiquid-phase exfoliation (LPE) is a versatile and scalable method for producing high-quality two-dimensional materials (2DMs). However, commonly used solvents such as dimethylformamide (DMF) or N-methyl-2-pyrrolidone (NMP) are highly toxic, limiting their potential for large-scale industrial applications. In this study, we address this challenge using Cyrene (dihydrolevoglucosenone), a nontoxic and biodegradabl...
Future weather generator for building performance research: An open-source morp...
Rodrigues, Eugénio; Fernandes, Marco S.; Carvalho, DavidMathematical morphing of historical weather data to match the projected climate change scenario is a commonly used method to generate future weather files for building energy simulation. It is known for preserving the local weather characteristics, which is particularly important when designing or analyzing high-performance buildings. Researchers may use one of the available morphing tools. Unfortunately, curre...
Blockchain Protocols and Edge Computing Targeting Industry 5.0 Needs
Oliveira, Miguel; Pereira, Filipe; Carvalho, David; Felgueiras, Carlos; Chauhan, Sumit“Industry 5.0” is the latest industrial revolution. A variety of cutting-edge technologies, including artificial intelligence, the Internet of Things (IoT), and others, come together to form it. Billions of devices are connected for high-speed data transfer, especially in a 5G-enabled industrial environment for information collection and processing. Most of the issues, such as access control mechanism, time to ...
Effects of climate change on aquaculture site selection at a temperate estuarin...
Pereira, Humberto; Picado, Ana; Sousa, Magda C.; Brito, Ana C.; Biguino, Beatriz; Carvalho, David; Dias, João MiguelAquaculture is one of the food industries that most evolved in recent years in response to increased human demand for seafood products, which has led to a progressive stock threat in nature. With a high seafood consumption per capita, Portugal has been exploring its coastal systems to improve the cultivation of fish and bivalve species with high commercial value. In this context, this study aims to propose the ...
A Review on the Current Status of Numerical Weather Prediction in Portugal 2021...
Monteiro, Maria José; Couto, Flavio; Bernardino, Mariana; Cardoso, Rita; Carvalho, David; Martins, João; Santos, João; Argain, José; Salgado, RuiEarth system modelling is currently playing an increasing role in weather forecasting and understanding climate change, however, the operation, deployment and development of numerical Earth system models are extremely demanding in terms of computational resources and human effort. Merging synergies has become a natural process by which national meteorological services assess and contribute to the development of...

Design e envelhecimento humano : conceitos aplicados à pessoa idosa
Carvalho, David; Paiva, Bartolomeu Adalberto FigueiredoBaseados no crescente envelhecimento populacional e no Design orientado para a inclusão, pretendemos contribuir para a reflexão sobre as necessidades da população idosa, mais concretamente sobre a inovação transposta para equipamentos de apoio a pessoas de idade avançada. O envelhecimento da pessoa representa uma conquistada da sociedade, e simultaneamente um desafio: o envelhecimento e um problema complexo que...
Comparison of different wind products and buoy wind data with seasonality and i...
Alvarez, Inés; Gomez-Gesteira, Moncho; deCastro, Maite; Carvalho, DavidOcean surface winds are essential factors in determining oceanographic and atmospheric processes that can affect ocean circulation and wave generation. Accurate surface wind datasets are needed, therefore, to enable the proper analysis of these processes. Wind data from six databases (National Centers for Environmental Prediction reanalysis (NCEP Reanalysis II), European Centre for Medium-Range Weather Forecast...
A sensitivity study of the WRF model in wind simulation for an area of high win...
Carvalho, David; Rocha, Alfredo; Gómez-Gesteira, Moncho; Santos, Carlos SilvaThe performance of the Weather Research and Forecast (WRF) model in wind simulation was evaluated under different numerical and physical options for an area of Portugal, located in complex terrain and characterized by its significant wind energy resource. The grid nudging and integration time of the simulations were the tested numerical options. Since the goal is to simulate the near-surface wind, the physical ...
Wind resource modelling in complex terrain using different mesoscale–microscale...
Carvalho, David; Rocha, Alfredo; Santos, Carlos Silva; Pereira, R.Wind resource evaluation in two sites located in Portugal was performed using the mesoscale modelling system Weather Research and Forecasting (WRF) and the wind resource analysis tool commonly used within the wind power industry, the Wind Atlas Analysis and Application Program (WAsP) microscale model. Wind measurement campaigns were conducted in the selected sites, allowing for a comparison between in situ meas...
