Low-cost portable sensor for uplastics differentiation
Penso, C. M.; Paiva, M. C.; Viana-Gomes, J.; Rocha, J.L.; Gonçalves, L. M.Na última década, os μplásticos tornaram-se um dos principais problemas de poluição nos oceanos, cursos de água e rios, atraindo atenção devido aos efeitos nocivos que provocam no meio ambiente e na saúde. Os métodos atuais para quantificação de μplásticos incluem imagiologia hiperespectral, espectroscopia de Raman e espectroscopia de infravermelho por transformadade Fourier (FTIR). No entanto, estes equipament...
Fast building – increasing the geometrical freedom of textile reinforced concre...
Monteiro, Filipa Maria Barbosa Faria; Cruz, Fábio Quintas; Neves, Ana Rita Rodrigues; Barajas, Diddyer Alexander Prada; Rocha, J.L.; Pereira, E. N. B.[Excerpt] Introduction Textile technology is highly innovative, and several techniques are already being used to act as building parts for fast building, interior design, architectural details and offshore structures. However, such potential still fails when complex geometrical structures or multifunctionality are required.
Effects of struvite recovered from wastes in crop cultivation
Oliveira, Verónica; Monteiro, M.C.H.; Rocha, J.L.; Ferreira, Célia D.Struvite recovered from wastes has been considered a promising second generation fertiliser. Themain objective of this work is to evaluate the effecls of struvite fertilisation on i) ryc (Secale cereale L.) cultivation (through a 45-d pot experiment), in terms of macronutrients, micronulrients and heavy metals and ii) on soil fertility (through a 30-d incubation experiment) in terms of available phosphorus and ...
