França, Alexandre S. (author), Brêda, Gabriela C. (author), De Oliveira, Kleber T. (author), Almeida, Rodrigo V. (author), Hollmann, F. (author), de Souza, Rodrigo O.M.A. (author)A visible-light-driven photocatalytic decarboxylation of palmitic acid and related fatty acids is described in this study. Remarkable decarboxylation rates have been observed with full conversion in less than 20 min. In this study, we have<br/>demonstrated that sunlight irradiation, even on cloudy days, can deliver similar results to traditional...journal article 2023

Foss, Ollie (author), Blenkinsopp, Chris E. (author), Bayle, P.B. (author), Martins, Kévin (author), Schimmels, Stefan (author), Almeida, Luis Pedro (author)Pressure on the coastline is escalating due to the impacts of climate change, this is leading to a rise in sea-levels and intensifying storminess. Consequently, many regions of the coast are at increased risk of erosion and flooding. Therefore coastal protection schemes will increase in cost and scale. In response there is a growing use of...journal article 2023

du Fossé, I. (author), Mulder, J.T. (author), Almeida, Guilherme (author), Spruit, Anne G.M. (author), Infante, Ivan (author), Grozema, F.C. (author), Houtepen, A.J. (author)One of the most promising properties of lead halide perovskite nanocrystals (NCs) is their defect tolerance. It is often argued that, due to the electronic structure of the conduction and valence bands, undercoordinated ions can only form localized levels inside or close to the band edges (i.e., shallow traps). However, multiple studies have...journal article 2022

(author), de Souza, Rodrigo O.M.A. (author)The fatty acid photodecarboxylase from Chlorella variabilis NC64A (CvFAP) promotes the elimination of CO<sub>2</sub> from fatty acids (C<sub>n</sub>) producing the corresponding hydrocarbon (<sub>Cn-1</sub>). Therefore, this enzyme is of great biotechnological interest since it can be used in alternative biofuel production routes matching the...journal article 2022

Wang, Z. (author), Almeida, José Humberto S. (author), Ashok, Aravind (author), Wang, Zhonglai (author), Castro, Saullo G.P. (author)Variable-angle filament-wound (VAFW) cylinders are herein optimized for minimum mass under manufacturing constraints, and for various design loads. A design parameterization based on a second-order polynomial variation of the tow winding angle along the axial direction of the cylinders is utilized to explore the nonlinear steering-thickness...journal article 2022

Design, modeling, optimization, manufacturing and testing of variable-angle filament-wound cylindersAlmeida, José Humberto S. (author), St-Pierre, Luc (author), Wang, Z. (author), Ribeiro, Marcelo L. (author), Tita, Volnei (author), Amico, Sandro C. (author), Castro, Saullo G.P. (author)This work demonstrates the potential of manufacturing variable-angle composite cylinders via filament winding (FW), called VAFW. The proposed design strategy allows different filament angles along the axial direction by dividing the cylinder into regions of constant angle called frames. Designs using two, four, or eight frames are herein...journal article 2021

(author)The calibration of hydrological models without streamflow observations is problematic, and the simultaneous, combined use of remotely sensed products for this purpose has not been exhaustively tested thus far. Our hypothesis is that the combined use of products can (1) reduce the parameter search space and (2) improve the representation of...journal article 2018
